The prevalence of abnormal semen parameters in male partners of women with anovulatory polycystic ovarian syndrome: a retrospective case-control study.

Polycystic ovary syndrome (PCOS) is the leading cause of anovulatory infertility, often requiring ovarian stimulation in affected women attempting to conceive. Male partner semen quality and shared lifestyle factors can significantly impact reproductive outcomes. However, current international guidelines lack evidence-based recommendations on the necessity and timing of semen analysis for the fertility management of anovulatory PCOS women. In a retrospective case-control study, semen analysis results of male partners of 187 anovulatory PCOS women scheduled for ovarian stimulation were analyzed and compared to a control group of 76 male partners of women with bilateral tubal occlusion. The prevalence of semen analysis results with at least one parameter classified as "borderline" and "pathological" among male partners of women with PCOS eligible to undergo ovarian stimulation was 51.3% and 22.5%, compared to 44.7% and 13.2% in the control group, respectively (p = 0.027). In the PCOS group, male body mass index (odds ratio, OR 1.478, p < 0.001), and smoking status (OR 6.228, p < 0.001) were significant predictors of pathological sperm test results, while no association was observed with any female characteristics (p > 0.05). The high frequency of pathological sperm analysis results provides lacking epidemiological data on semen quality in this population, emphasizing the critical need for early male fertility evaluation prior to ovarian stimulation in PCOS women. Moreover, our findings indicate that the risk prediction for abnormal semen quality cannot be based on the female's data.

Role of varicocelectomy in infertile patients with clinical varicocele and isolated sperm defects

ObjectiveThis study investigated the outcomes of microsurgical subinguinal varicocelectomy (MV) on semen and hormonal parameters in cases with isolated sperm defects (oligo-, astheno-, or terato-zoospermia). MethodsRetrospective review of charts of patients who underwent MV for clinically palpable varicocele between 2011 and 2019 at our institution was undertaken. All patients diagnosed with isolated oligo-, astheno-, or terato-zoospermia in the preoperative semen analysis were included. Men with azoospermia, history of genitourinary infection, or utilizing peri-operative fertility medications were excluded. Collected data included patient demographics, and results of routine semen analysis, DNA fragmentation, and hormone parameters (follicle stimulating hormone, luteinizing hormone, testosterone, and estradiol) before MV and up to 6 months postoperatively. ResultsA total of 331 patients with isolated sperm defects were included. Postoperatively, 83.3 % of isolated oligozoospermic patients showed a significant improvement in sperm concentration. Among isolated asthenozoospermic men, 76.7 % and 66.0 % showed postoperative significant improvement of total and progressive motility, respectively. For the teratozoospermic group, 70 % of patients showed a significant improvement in normal morphology. No changes were observed in other semen or hormone parameters that were examined. ConclusionMV is a valid and effective treatment modality for patients with isolated sperm defects that significantly corrects their respective semen abnormality and improves their chances of natural conception.

P-381 Fertility preservation in patients with testicular cancer

Abstract Study question Do the clinical stage and histological characteristics of testicular cancer affect sperm quality? Summary answer Sperm concentration, motility and normal morphology significantly decreased in patients with testicular cancer. However, semen parameters were not significantly associated with tumor histology. What is known already Testicular cancer is rare in most countries, with an incidence ranging from ∼1/100,000 to 10/100,000, and represents about 1% of all cancers in men, but about 60% of all cancers in young males aged between 15 and 35 years. Additionally, the incidence of testicular cancer has doubled in the last 20-40 years. While it is clear that chemotherapy treatment can negatively impact infertility, it is increasingly recognized that male-factor infertility may play a significant role in the overall health status of men, and men with infertility may be at higher risk of developing testicular cancer. Study design, size, duration Retrospective data from 284 males, diagnosed with testicular cancer, undergoing to semen cryopreservation before surgery or chemo- or radiotherapy treatments, from January 2016 to June 2022 at Maternal and Child Department, Gynecology and Obstetrics Unit, Couple Sterility Center at Federico II, University of Naples, were included in the study. Participants/materials, setting, methods All patients signed their informed consent to cryopreservation. In order to have an internal control group coming from the same region, results of semen analysis from male partners of couples with certain female factors (bilateral tubal imperviousness or in case of egg donation) were included in the study. After semen collection and liquefaction, the semen specimens were cryopreserved following manufacturer’s protocol with media conteining TEST-yolk buffer. Main results and the role of chance Overall, taking in to consideration the semen cryopreservation, per WHO 2021 criteria, we observed that the majority of semen parameters of patients with testicular cancer resulted between 5°percentile and 25° percentile. The unique parameter over the 50°percentile was the semen volume. Comparing results from male partners of couples with certain female factors and testicular cancer patients several features were significant different. Especially, semen volume resulted significantly increased in cases respect to the control (p = 0,011). Instead, from microscopic evaluation semen concentration, percentage of total sperm motility and % of spermatozoa with normal morphology appeared significantly decreased in patients with testicular cancer (p = 0,000; p = 0,000; p = 0,002). Based on Histopathological Classification of Testicular Tumors the 59% (168/284) were classified as classic seminoma, 14% (41/284) mixed germ cell tumors including seminomatous and nonseminomatous cell tumors, 13% (38/284) nonseminomatous mixed germ cell tumors, 12% (35/284) nonseminomatous germ cell tumors including 4 cases of teratoma and 30 cases of embryonal carcinoma and 2 cases of cariocarcinoma. However, abnormal semen parameters were not significantly associated with tumor histology. Limitations, reasons for caution No information about semen quality after thawing and ICSI outcome could represent the main limitation for a complete information of the preservation program in these patients. Wider implications of the findings We presented our monocentric experience of oncofertility preservation program with especially attention to testicular cancer patients. Presented data emphasizes the importance of semen monitoring in young men and the fertility preservation in management of the patient. Trial registration number not applicable

Comparative Evaluation of Prostatic Smear and Semen Analysis in The Diagnosis of Chronic Prostatitis

Abstract Background Chronic prostatitis is one of the most common medical problems among andrology and urology patients. Besides being the primary problem in many cases, it seems to play an important contributing role “major or minor” in a significant proportion of patients whether at the level of fertility, sexology or venerology. Consequently, effective management of the prostatic pathology has a great impact on the overall successful management of such andrologic problem. Aim of the Work to provide an objective comparison between traditional prostatic discharge analysis and traditional semen analysis as regards detection of pus cells in cases of prostatitis as well as to assess the possible advantage(s) of applying some modifications to enhance the diagnostic value of the previous techniques. These would include preliminary centrifugation of expressed prostatic discharge and preliminary peroxidase staining of semen sample before microscopic examination. Patients and Methods This pilot study included 40 patients suffering from prostatitis except acute prostatitis. The patients were recruited from the outpatient clinic of Venerology and Andrology department of Ain Shams University Hospitals in the period from February 2021 to November 2021. Results The current study included 40 patients suffering from any kind of prostatitis except acute prostatitis. Their age ranged between 30 and 50 years old with a mean age of 39.60 ± 4.52 years. Duration of disease ranged from 4-18 months with a mean of 7 ± 3.1 months. Most of patients were married (38, 95%). Main symptoms presented among studied patients were groin pain (37.5%), groin pain and painful micturition (20%) and groin pain, painful micturition and sexual problems (42.5%) Conclusion prostatic smear examination revealed higher sensitivity in detection of infection compared to semen analysis especially if combined with centrifugation. In addition, peroxidase positive cell testing revealed a significant role in detection of infection if the diagnosis is made solely on semen analysis results.

Retrospective study investigating the performance of the SQA-vision analyser compared with manual semen analysis

The objective of this study was to compare the results of semen analysis using the manual method and the SQA-Vision sperm analyser after four years of practice and with a large cohort of patients. This was a comparative study of 1130 cases collected for semen analysis between October 2019 and October 2023, which were analysed simultaneously and independently by different operators using the manual microscopic method and an SQA-V automated analyser. For each sample, sperm concentration, progressive motility, motility, normal morphology, and round cells count were performed. There was no significant difference between the SQA-V method and manual assessment for all sperm parameters (Mann–Whitney test p > 0.05). According to the parameter studied, there was a strong correlation (rho = 0.81) and a very high correlation (rho = 0.98) between manual assessment and the SQA-V method. In the analysis of sperm concentration, the sensitivity and specificity were 0.90 and 0.99, respectively. The sensitivity and specificity for the analysis of sperm progressive motility were 0.98 and 0.99, respectively, while the sensitivity and specificity for the analysis of sperm motility were 0.87 and 0.99, respectively. The sensitivity and specificity for the analysis of normal morphology were 0.88 and 0.99, respectively. Regarding the analysis of round cells, the sensitivity and specificity were 0.98 and 0.99, respectively. The results of this retrospective study indicate that the SQA-V system offers satisfactory performance for routine sperm analysis.

Testicular ultrasound measurement of testicular volume and epididymis diameters: Prediction of semen quality in a prospective study

AbstractPurposeTo identify the most predictive ultrasound parameters for the assessment of male infertility by a multiparametric study.Materials and MethodsA total of 64 males were recruited in the study group and 14 men in the control group. At first, grey-scale and color and Power Doppler ultrasonographic imaging was used to analyze testicular morphological characteristics and detect intratesticular abnormalities. Various ultrasound parameters of B-mode US and strain-elastography were related to total sperm count (TSC).ResultsThe prevalence of varicocele was not significant (P = 0.33), though presented a 2.53-fold odds ratio The strain ratios of both testes, the volume of the left testis and the size of the left appendix were most associated with the results of semen analysis according to a Variable Importance in the Projection (VIP) score of &gt;1. The first latent variable from the PLS analysis explained a significant amount of variance in TSC, concentration, and motility parameters (P &lt; 0.0002) and showed that bilateral strain ratio, the size of the testis, and the volume of left appendix were the most significant US predictors of the pathological semen and sperm cell features.ConclusionsOur results showed that B-mode US with strain elastography is among more sensitive US approaches in evaluating male fertility.

Spermatogenesis induction audit over a 5-year period at a UK male fertility centre

Background: This audit aimed to evaluate and measure the outcomes of spermatogenesis induction over a 5-year period. Men with primary, as well as central hypogonadism, received gonadotrophin therapy to stimulate sperm production and fertility outcomes, including live birth rates. Predictors associated with live births, were measured retrospectively. Methods: Men with severe oligospermia (sperm concentration &lt;5million/ml), having gonadotrophin prescriptions for a minimum of 6 months, were identified via the electronic prescription system. They were asked to complete a service evaluation questionnaire. Results: Men with persistent azoospermia were more likely to have a diagnosis of PH (Odds ratio 22.5, p&lt;0.001) and smaller testicular size (Odds ratio 8.8, p&lt;0.001), compared to men with successful spermatogenesis. Twenty-eight per cent (13/47) had partners, who conceived spontaneously and delivered healthy babies. Nine per cent (4/47) had a live birth after ART. Live birth rate was higher in men with CH compared to PH, with 17 of 45 (38%) men with CH having a partner that successfully delivered a baby. Conclusion: Men with mainly central hypogonadism and female partners with no known subfertility are most likely to achieve conception and live birth. Patient education on the results of semen analysis or female factors affecting fertility could improve overall outcomes.

Distribution and Positive Predictive Value of Follicle Stimulating Hormone Among Nonazoospermic Men.

Our goal was to characterize the distribution of follicle stimulating hormone (FSH) in fertile and subfertile nonazoospermic men, and to determine the ability of various FSH thresholds to predict fertility status. We performed a retrospective cohort study of 1389 nonazoospermic men who presented for fertility evaluation. Men with at least 2 semen analyses and 1 FSH level were included. Men were dichotomized into fertile and subfertile groups based on total motile sperm count. FSH was evaluated within a multivariable model, and positive predictive values (PPVs) for subfertility were used to assess the clinical utility of various FSH thresholds. One thousand fifteen (80%) men were classified as fertile and 274 (20%) as subfertile. Age, presence of varicocele, and testosterone levels were not statistically different between the groups. Median FSH was 4.0 vs 6.0 (P < .001) among fertile vs subfertile men. Multiple FSH thresholds ranging from 2.9 to 9.3 performed similarly in predicting fertility status (PPV 0.49-0.59). Only FSH thresholds above the 95th percentile (12.1) had PPVs greater than 0.7. The highest PPV (0.84) was seen at an FSH of 20.8 (99th percentile). While there were significant differences in FSH levels among fertile and subfertile nonazoospermic men, multiple FSH cutoffs between 2.2 and 9.3 performed poorly for prediction of fertility status as determined by total motile sperm count. It was not until the 95th percentile FSH value that a clinically useful level of predictability for subfertility was reached, indicating that FSH should not be used as a standalone test of fertility status. Nonetheless, FSH testing remains clinically useful and may be most informative in the setting of extreme values or discordant FSH and semen analysis results.

(093) The Continued Use of Testosterone Does Not Interfere with Human Chorionic Gonadotropin-Mediated Return of Spermatogenesis

Abstract Introduction Depression of spermatogenesis is a significant problem in the hypogonadal patient on testosterone therapy (TTh). We commonly prescribe human chorionic gonadotropin (hCG) concomitantly in these men to prevent testicular atrophy and to maintain some degree of spermatogenesis. When a pregnancy is desired, we increase the hCG to 3000 units subcutaneously three times weekly. Traditionally, testosterone therapy is discontinued during this high-dose hCG treatment. However, the question remains as to whether these men can continue TTh with the use of hCG, thus bypassing the need to stimulate pituitary hormones. Objective To investigate whether patients with low testosterone, in an effort to avoid hypogonadal symptoms, can continue their testosterone therapy when using hCG in an effort to reestablish normal spermatogenesis. Methods We studied 260 patients who had been prescribed hCG at a university hospital within the observation range of 01/01/2021–12/31/2022. Two cohorts were evaluated: hCG + TTh and hCG without TTh. Dosage information, other medications, comorbidities, demographic information (including age and race), as well as laboratory results of hormones and semen analyses were captured into a patient database. Baseline laboratory values for each patient were documented prior to being prescribed hCG, followed by subsequent values for each of these variables in the months following this prescription. One-way ANOVAs were employed using SPSS to analyze the longitudinal impacts of hCG on testosterone, total sperm count, and total motile count. For the analysis of testosterone values, we separated patients based on whether they were concomitantly prescribed and taking testosterone therapies (TTh). Results When assessing the baseline testosterone in patients on TTh compared to the following four follow-up visits (n=154) since taking hCG, the f-ratio of the one-way ANOVA was 9.13256 (p-value &amp;lt; 0.00001). In the same assessment for patients not on TTh (n=37), the f-ratio value is 4.93955 (p-value = 0.0011). Lastly, when analyzing total sperm count across all patients with documented semen analyses (SA) across four follow-up visits (n=64) since taking hCG, the f-ratio value is 2.66654 (p-value = 0.034). Both cohorts experienced improvements across these two metrics. Our data did not show any statistically significant differences in the two groups in total motile count across the follow-up visits. Conclusions Our findings confirm strong improvements in testosterone and total sperm count, regardless of whether or not adjunctive TTh was used. These results highlight the efficacy of hCG longitudinally in promoting hormonal and reproductive recovery in hypogonadal men, warranting further investigation into its long-term effects and clinical applications. These data provide valuable insights that can assist healthcare professionals in providing informed guidance to patients regarding the anticipated therapeutic outcomes of hCG treatment, including expected timeline and magnitude.

Camel filariasis (Dipetalonema evansi) and its association with clinical balanoposthitis with reference to prominent changes in clinical findings, serum testosterone, semen analysis, and testicular histopathology

BackgroundCamel filariasis induced variable clinical syndromes characterized by fever, lethargy, localized dermal lesions, loss of condition, and testicular and scrotal swelling. The objective of the present work focused on clarifying the diagnostic importance of clinical findings, serum testosterone, and semen analysis as well as blood smear and testicular histopathology as a differential tool between only balanoposthitis without filariasis male camels group (OnlyBpgr) and balanoposthitis-filariasis infected male camels group (BpFlgr). The study also monitored the associations between the severity of ticks’ infestations in investigated male camels and the occurrence of balanoposthitis only or balanoposthitis with filariasis.Results and conclusionsThe study reported significant correlation between serum testosterone, serum cortisol, and sperm vitality and abnormalities percentages. The study included male camels (n = 250) classified into three groups: healthy control group (Contgr; n = 30), OnlyBpgr (n = 210), and BpFlgr (n = 10). These male camels were clinically and laboratory examined, and skin scraping tests and testicular histopathology were conducted. The study confirmed the association of the changes in clinical findings, whole blood picture, serum testosterone, serum cortisol, and semen analysis, with OnlyBpgr and BpFlgr. These changes were more prominent in BpFlgr than in OnlyBpgr. Skin scraping test results revealed a higher severity of live ticks’ infestation in BpFlgr than in OnlyBpgr because, unlike OnlyBpgr, all camels in BpFlgr (n = 10) were suffering from live ticks’ infestation. It also concluded the higher efficacy of histopathology of testicular tissues in male camels as a diagnostic tool for adult filaria in balanoposthitis-affected male camels than blood smear because all cases of camel filariasis in the current work were negative for microfilaria on microscopic examination of diurnal blood smear as well as testicular histopathology revealed detection of adult filaria in all camel filariasis associated with balanoposthitis. Strong correlation relationships were demonstrated between serum testosterone, serum cortisol, and semen analysis results. Positive correlations were reported between serum testosterone levels and sperm vitality percentages. However, negative correlations were stated between serum testosterone and each of serum cortisol and sperm abnormalities either in Contgr, OnlyBpgr, or BpFlgr.

Chromosomal analysis of single sperm cells from infertile couples with severe oligoteratozoospermia: A cross-sectional prospective study.

In this cross-sectional prospective study, advanced next-generation sequencing technology was used to compare the molecular karyotyping of individual human sperm cells in infertile couples with severe oligoteratozoospermia (i.e., low sperm count and motility) to those of infertile couples with normal semen. Fourteen infertile couples who were patients at Ramathibodi Hospital in Bangkok, Thailand, were recruited from January to November 2023, and they were categorized into two groups based on semen analysis results. The study group comprised couples with severe oligoteratozoospermia, whereas the control group exhibited normal semen. Individual sperm cells from the semen samples were isolated by the micromanipulation technique for subsequent whole-genome amplification and next-generation sequencing, where the primary outcome was the aneuploidy rate. Seventy individual sperm cells were isolated with a 90% success rate for amplification. The next-generation sequencing results showed that the aneuploidy rate was 25%-75%, with a mean of 48.28% in the study group. In contrast, the control group exhibited aneuploidy rates of 0-75%, with a mean of 15.15%. The difference between the two groups was statistically significant (odds ratio: 5.8, 95% confidence interval: 1.30-26.03). Sperm cells of the study group showed a threefold higher aneuploidy rate than those in the control group, even though the sperm cells were selected by micromanipulation for their normal morphology. Comprehensive counseling is recommended to address elevated aneuploidy rates that potentially surpass those of the general infertile population. Guidance on preimplantation genetic testing is also recommended to ensure the transfer of embryos with normal chromosomes.

Evaluating male sexual function and reproductive health during Omicron outbreak in China.

There are currently no studies exploring omicron infection and male sexual function and semen quality. Our aim was to estimate changes in sexual function and semen quality in men recovering from infection since the COVID-19 Omicron pandemic started in China in late 2022. We collected 1540 questionnaires and assessed male function before infection and acute phase after infection by using International Index of Erectile Function-5, Premature Ejaculation Diagnostic Tool, and Arizona Sexual Experience Scale. We also collected the before and after semen analysis results of 247 male patients. During the acute phase after infection, the proportion of erectile dysfunction was significantly higher than before infection, but ejaculatory function was not significantly altered; In addition, semen analysis showed significant difference in semen concentration, semen activity and PR a+b sperm forward movement after infection compared to pre-infection.: COVID-19 Omicron can affect erectile function as well as sexual experience in male patients in the acute phase. Decreased sexual function due to COVID-19 Omicron may be related to body temperature and anxiety during infection.

Recommendation to diagnose male factor infertility based on routine semen analysis results

It is apparent that sperm parameters like concentration, motility and morphology are not definitive/adequate fertility measures as sperm is a heterogeneous mixture, and sperm quality is determined by only what is visible in the microscopic field. Objective was to assess the quality variation among different aliquots of an ejaculate and present a concept that may allow interpreting the results in such a way as to determine the clinical usefulness of the semen analysis more accurately.A laboratory-based cross-sectional study was conducted at Teaching Hospital Jaffna’s Semiology laboratory from July to September 2023 after obtaining Institutional Ethical Review committee approval, analysing 102 semen ejaculates collected through masturbation. The sample was analysed using a Makler counting chamber, and Data was analysed using SPSS version 24, with statistical significance set at P&lt; 0.05.The three different aliquots obtained from the same ejaculate revealed no significant difference from each other for all three variables like Concentration (P=0.957), Progressive Motility (P=0.810) and Motility (P=0.832). Similarly, the mean and fifth percentile plus 95% confidence level were not significantly different (P= 0.782, P= 0.328, P= 0.370).When using the Makler counting chamber, the mean value calculated from one aliquot per ejaculate counted on three strips of ten squares should be acceptable, and at least two different ejaculates should be analysed when interpreting the results based on World Health Organization (WHO, 2021) reference limits.

Testicular appendix (hydatid of Morgagni) torsion in adult urological management: evaluation of treatment outcomes

Introduction. Testicular appendix (hydatid of Morgagni) torsion (TAT) is relatively rare in patients over 18 years of age. To date, there are no systematised data on the long-term results of TAT treatment depending on the diagnostic and therapeutic tactics undertaken. Accordingly, there are no clear algorithms for the management of such patients.Objective. To evaluate and compare long-term results of various treatment options for patients with testicular appendix torsion over the age of 18 years.Materials &amp; methods. The age of patients is from 18 to 46 years. We analysed the treatment results of TAT-patients in three comparison groups: those who received conservative treatment for uncomplicated course of the disease (group 1, n = 17), early surgical treatment for complicated course (group 2, n = 16), and patients who were operated on for complicated course if conservative therapy was ineffective (group 3, n = 17). The exclusion criteria were concomitant scrotal pathology (hydrocele, funicular hydrocele, varicocele, epididymitis); severe somatic pathology (diabetes mellitus, hypertension, heart attack, stroke). Evaluation of long-term results was carried out 9 – 12 months after the acute episode. Scrotal ultrasound (US) and Doppler US of testicular vessels were compared, endocrine status (levels of total testosterone, luteinising hormone, follicle-stimulating hormone) and reproductive function were studied based on the results of semen analysis and MAR-test.Results. Analyses of long-term clinical data revealed recurrent orchalgia in 29.4% of patients in group 3. Also, in group 3, US revealed testicular asymmetry in 47.1% of patients accompanied by hypotrophy of the affected testis up to 20.8% of the volume compared to the contralateral testis. There were no significant changes and differences in groups 1 and 2. Evaluation of endocrine function showed no significant difference of the studied groups from the control normative indicators. Semen analysis parameters were not significantly changed in groups 1 and 2. In group 3, asthenozoospermia was found in 23.5% of cases, and teratozoospermia was detected in 29.4% of patients.Conclusion. Conservative treatment for TAT without inflammatory changes does not lead to impaired spermatogenesis and structural changes of both the testis and its appendix in the long-term follow-up period and is the most accepted in practice. Early surgical intervention for inflammatory changes shows similar long-term results. Prolonged conservative treatment for TAT in secondary orchoepidididymitis with delayed surgery significantly worsens long-term results. This fact also demonstrates the need for early surgery in complicated TAT.

Effect of Medicago sativa seed powder (Plus vitamin E vs. vitamin E alone) on semen analysis in men with idiopathic infertility: A double blind randomized clinical trial

Ethnopharmacological relevanceDifferent parts of the alfalfa plant (Medicago sativa L.), especially its seeds, have been introduced as a semen quality enhancer in the folk medicine of different regions of Iran as well as in the traditional Persian medicine (PM) books. The seeds of this plant are also used in many combined medicines to treat male infertility in PM. Aim of the studyThis study was designed to investigate the effect of M. sativa seed powder plus vitamin E vs. vitamin E alone on semen analysis of men with idiopathic infertility. Materials and methodsIn this randomized clinical trial, 60 participants were randomly divided into two groups and then received M. sativa seed powder (6 g daily) or placebo for three months, as add-on to vitamin E (100 U). Results of semen analysis (sperm total count, motility, and morphology as well as semen volume) of these two groups and their changes were compared before and after treatment as the primary outcome. The number of pregnancies after one month and probable side effects were also assessed. ResultsAfter 12 weeks, sperm total count changed from 36.2 ± 21.8 × 106/ml to 48.5 ± 19.1 × 106/ml in M. sativa and from 39.5 ± 23.5 × 106/ml to 41.2 ± 20.9 × 106/ml in placebo, percentage of normal morphology changed from 1.8 ± 0.8% to 2.6 ± 1.2 % in M. sativa and from 2.0 ± 0.9% to 2.6 ± 1.2% in placebo and percentage of motile sperm changed from 36.5 ± 11.8 % to 39.7 ± 12.0% in M. sativa and from 39.3 ± 10.1 % to 38.1 ± 12.1% in placebo. The improvements in M. sativa group are significantly better than placebo group (P = 0.00, 0.01 and 0.04, respectively). However, semen volume decreased in both groups, but its changes were not significant. The number of pregnancies was four in the intervention and zero in placebo group. One case with abdominal bloating and one with respiratory allergy withdrew from the intervention group. No other adverse effect was reported. ConclusionsIn this study, significant improvement was detected in sperm parameters (except semen volume) of men with idiopathic infertility in M. sativa plus vitamin E group in compare to vitamin E alone after 12 weeks. These findings suggest that the M. sativa, as a complementary therapy, may have a beneficial effect on semen quality. More clinical trials with larger sample size are needed.

Detection of chromosome aberrations in 17 054 individuals with fertility problems and their subsequent assisted reproductive technology treatments in Central China.

How do the types and frequency of chromosome aberrations in couples in central China affect fertility and ART treatment? Men with chromosome aberrations or polymorphisms have an increased risk of semen quality impairment and infertility, and couples affected by reciprocal translocations had a lower pregnancy rate compared with other chromosome aberrations. Karyotyping is crucial for patients affected by infertility as chromosome aberrations play an important role in the etiology of male infertility. However, the influence of chromosome aberrations and polymorphisms on sperm motility and morphology remains controversial. Data on ART treatment outcomes in infertile couples affected by chromosome aberrations are insufficient. We conducted a retrospective study involving 17 054 patients affected by infertility who underwent karyotyping in our center between January 2020 and May 2022. Karyotyping was performed on 17 054 patients with reproductive failure. All patients were from the central regions of China. The following data were collected from a medical records system using patient identification numbers: couples' ages, history of pregnancy and childbirth, type of infertility, years of infertility, cause of infertility, chromosome karyotypes, semen analysis results, assisted reproductive techniques performed, and treatment outcomes of ART. The incidence of chromosome aberrations was 2.04%; 2.49% in men and 1.57% in women. By analyzing the relationships between chromosome aberrations/polymorphisms and abnormal semen parameters, we found that there were significantly higher rates of asthenozoospermia, oligospermia, and teratozoospermia among men with Robertsonian translocations and sex chromosomal structural aberrations compared with those with normal karyotypes. Higher rates of asthenozoospermia and teratozoospermia were also observed among men with autosomal reciprocal translocations. The incidence of chromosome aberrations in azoospermic men (13.75%), and in men with cryptozoospermia or severe oligospermia (6.97%) was significantly higher than that in men with mild oligospermia or normospermia (0.88-2.12%). In addition, we found that the progressive movement of sperm is impaired in men with Chromosome 21 polymorphisms compared with men with normal karyotypes (39.46% ± 20.51% vs 48.61% ± 18.76%, P = 0.026). The percentage of morphologically normal forms was lower in the chromosomal polymorphism group than in the normal karyotype group (5.01% ± 2.41% vs 5.59% ± 2.14%, P = 0.001), especially in men with polymorphisms on Chromosome 9 (enlarged Chromosome 9 heterochromatin [9qh+]: 4.48% ± 2.22% vs 5.59% ± 2.14%, P = 0.006; pericentric inversion of Chromosome 9 [inv(9)]: 5.09% ± 3.11% vs 5.59% ± 2.14%, P = 0.008). ART treatment was successful in 36.00% of couples affected by chromosome aberrations. However, couples affected by reciprocal translocations achieved a lower pregnancy rate (24.07%), which may be due to the lower euploidy rates (27.31%) when compared with that in other chromosome aberrations. First, although the initial cohort was large, chromosome aberrations were identified in a small number of patients. Second, the observational nature of the study design is limiting. Third, the couples affected by infertility in this study were all outpatients that did not undergo identical comprehensive examinations except for karyotyping, leading to the incomplete collection of medical records. Also, the population included in this study mainly focused on couples affected by infertility, which may not be included in the European Association of Urology (EAU) recommendation on male infertility. Men with chromosome aberrations or polymorphisms have an increased risk of semen quality impairment and infertility. Constitutional chromosome analysis is recommended for men affected by infertility and severe oligospermia or azoospermia to facilitate early and appropriate guidance for the most suitable treatment. Carriers of chromosome aberrations can achieve acceptable pregnancy outcomes through IVF. However, couples affected by reciprocal translocations have lower pregnancy rates, and more treatment cycles are needed before a successful pregnancy.

The Variability of Semen Parameters With Sexual Abstinence Using Mail-in Sperm Testing Is Similar to That Seen With Traditional In-Office Semen Analysis.

The impact of ejaculatory abstinence on semen parameters using in-office semen analyses has been well-established; however, their variability has not been evaluated in men using mail-in semen analysis kits. Our study aims to describe how the sperm parameters using mail-in semen analysis tests change with abstinence and validate their equivalence to those seen with in-office semen analysis tests. We retrospectively reviewed the semen analysis results of men using mail-in semen analysis tests provided by Give Legacy, Inc (Legacy) facilities from 2019 to 2021. We collected their demographic information, abstinence duration, and semen parameters (conventional and kinematic) from their records. Semen samples were categorized as normozoospermic and oligozoospermic based on concentration. The shape of the relationship between abstinence duration and semen parameters was assessed via generalized additive models. We have collected 3,469 unique samples provided by 2,609 (75%) normozoospermic men and 860 (25%) oligozoospermic from all over the United States. In normozoospermic men, longer periods of sexual abstinence were linked to higher levels of sperm concentration, total sperm count, and total motile sperm. However, there was a decline in both total and progressive motility. Conversely, in oligozoospermic men, extended periods of abstinence led to a rapid decline in total motile sperm, as well as total and progressive motility. There was no significant correlation observed between sexual abstinence and variations in sperm morphology. Our study shows that variability of sperm parameters with abstinence, as measured through mail-in semen analysis tests, is comparable to the patterns observed with conventional in-office sperm testing.

Impact of semen oxidative stress on sperm quality: initial results from Vietnam.

This study aimed to determine the relationship between oxidative stress (OS) measured by the oxidation-reduction potential (ORP) and the results of semen analysis among men from infertile couples. This cross-sectional study included 166 men from infertile couples, determined according to the World Health Organization guidelines. The general characteristics, semen analysis, sperm chromatin dispersion assay, and ORP of all subjects were evaluated and analyzed statistically. Among 166 men from infertile couples, individuals with OS had a significantly higher DNA fragmentation index (DFI) than men without OS (22.37% ± 11.67% vs. 17.98% ± 8.98%). The sperm concentration, total sperm count, motility rate, and normal morphology were negatively correlated, while and an abnormal head and neck-tail were positively correlated with ORP. There was also a positive association between the DFI and OS level. The optimal ORP threshold for determining sperm quality was 0.77 mV/106 sperm/mL (sensitivity, 50.4%; specificity, 93.5%; positive predictive value, 52.9%; negative predictive value, 32.3%). Determining the ORP suggests that OS has an adverse effect on the total sperm count, sperm motility, sperm concentration, morphology, vitality, and DNA fragmentation index.

Semen's parameters after varicocelectomy surgery with mast cell stabilizers treatment in infertile varicocele patients: Randomized clinical trial study.

Varicocele is one of the most common causes of male infertility in which testicular function is progressively damaged. This study aims to investigate the effect of varicocelectomy and mast cell stabilizers on reducing sperm DNA fragmentation in infertile patients with varicocele. In this randomized clinical trial, after obtaining ethical approval and informed consent, infertile patients with varicocele were randomly assigned to three groups: varicocelectomy, 1 mg ketotifen, and varicocelectomy plus with 1 mg ketotifen for 3-month follow-up. Semen analysis and estimation of DNA fragmentation index (DFI) were obtained from all people in the studied time periods. In this study, 420 infertile patients with varicocele were included with an average age of 31.6 years. The results showed that sperm morphology, sperm motility, sperm count, and sperm DFI had significant differences after the intervention (p < 0.05). Also, the results of semen analysis for each group showed that there was a significant improvement in sperm morphology, motility, count, and DFI index of infertile people with varicocele after the intervention (p < 0.05). But the difference was statistically higher in the varicocelectomy plus with 1 mg ketotifen group than in the other groups (p < 0.01). The evidence and results of this study showed that the use of varicocelectomy plus ketotifen in infertile people with varicocele was more effective in improving Semen parameters than the use of mast cell stabilizers or varicocelectomy alone.

Computer-assisted semen analysis in large falcons (Falco spp.) and comparison to results of conventional semen analysis

Numerous raptor species including some falcon species are facing continuous population decline in the wild and some are threatened by extinction. To support these species, captive breeding and reintroduction programs are attempted. Besides conservation, some large falcon species are commonly used in falconry and therefore bred commercially. Assisted reproduction is established in falcon breeding since the 1970s and semen analysis is an integral part to enable assessment of breeding males, inclusion or exclusion of semen donors and quality control of semen prior to artificial insemination. Conventional methods for semen analysis are widely used, but are time consuming and depend on the investigator's experience and ability. Computer-assisted semen analysis (CASA) would offer an objective, fast and reproducible alternative, but as they have not been established in large falcon species, this was the aim of this study. To this end, we examined in 3 breeding seasons 109 semen samples of gyr-saker hybrid falcons (n=2) and peregrine falcons (n=4) in 940 fields of view using the Minitube CASA SpermVision and compared these results to results of conventional methods of semen analysis. We used a preprogrammed setting and adapted two settings of CASA according to specific semen characteristics of falcons. Sperm velocity, motility and viability parameters were recorded successfully using CASA. Correlation of conventional and computer-assisted motility analysis improved during the process of adaptation of CASA settings, but both methods differed significantly due to misinterpretation of round bodies and semen impurities by CASA. Viability values of conventional and computer assisted viability analysis using SYBR-PI correlated significantly while sperm concentration did not at all. CASA failed to replace conventional semen analysis regarding sperm motility and sperm concentration using 3 different settings, as a reliable differentiation between spermatozoa, spermatids and round bodies was not achieved. Using CASA, sperm velocity parameters were measured in spermatozoa of captive-bred large falcons for the first time and may be used as orientation values.
