Distribution and Positive Predictive Value of Follicle Stimulating Hormone Levels 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.

Early breast development in girls: the power of greyscale sonography and sonoelastography.

Accurate distinction between central pubertal precociousness (PP) and premature thelarche (PT) is important to guide treatment. Both greyscale ultrasonography (US) and sonoelastography can be used to examine breast tissue. The aim of this study is to investigate the performance of breast US and strain elastographic (SE) in the diagnosis of increased breast volume in girls. Sixty-three girls with breast development up to 8 years of age and diagnosed with PP and PT were included in the prospective study. Basal luteinizing hormone (LH), follicle-stimulating hormone (FSH), and estradiol (E2) values were obtained. Each bud was considered as a unit in US. Mediolateral (ML) and anteroposterior diameters (AP) were measured, and US grading was performed. Breast SE was examined, and strain index (SI) was calculated. US and laboratory findings were compared. Of the 121 buds examined, 39 (32.2%) were with PP (6.97 ± 2.44 years) and 82 (67.8%) were with PT (6.51 ± 2.52 years). Diameters were correlated with bone age, LH, FSH, and US grade. The mean AP showed a moderate difference in favour of PP between the groups (P < .06). The mean ML was higher in PP (P < .01). There was a difference in mean SI values (P < .004). Sensitivity and specificity were 71% and 61% for ML and 72% and 56% for SI, respectively. Both ML and US grading may help discriminate PP from PT. The role of sonoelastography requires further investigation. Ultrasound and SE show significant differences between PP and PT, but these are not sufficiently reliable to be of clinical use. The contribution of sonoelastography requires further study before it can be recommended. However, SI of breast tissue can be helpful in distinguishing PP and PT from other causes of early increase in breast volume.

ASSOCIATION OF POLYCYSTIC OVARY SYNDROME AND THYROID DYSFUNCTION AMONG REPRODUCTIVE WOMEN: A CROSS-SECTIONAL STUDY

Objective: Polycystic ovarian syndrome (PCOS) is became most common problem in the reproductive age group women who seem to be adversely affected by associated thyroid dysfunction. Ovarian failure and pregnancy-related complications leaded by both factors. The study helps to explore the incidence and etiology of diverse thyroid conditions among PCOS individuals. Methods: This prospective single‑center study with 40 female patients with hyperandrogenism, hirsutism, oligo‐anovulation, and polycystic ovaries patients were defined as having PCOS according to the revised 2003 Rotterdam criteria and Ferriman–Gallwey score with comprised the study population. Normal female subjects were studied as the control population who had normal thyroid function and without PCOS. By measuring of serum thyroid-stimulating hormone (TSH), free thyroxine levels (free T3 and free T4), follicle-stimulating hormone (FSH), luteinizing hormone (LH), estrogen, progesterone, and testosterone can evaluate thyroid function. Along with ultrasound was performed to confirm the PCOS. By SPSS version 19 Chi-square test and t-test were determined. Results: This case–control study revealed that a statistically significant higher prevalence of PCOS patients was found to have higher mean TSH values that were 5.33±2.51 μIU/mL, the mean for T3 and T4 was 154±138 μg/dL and 11.27±8.47 μg/dL, respectively. The mean FSH values were 07.27±4.49 μIU/mL, the mean LH was 84.27±38.49 μIU/mL, the mean estrogen 342±202 pg/mL, the mean progesterone values were 14.2±8.9 ng/mL and the mean testosterone levels were 69.73±9.28 ng/mL. Conclusion: Thyroid dysfunction shows a high prevalence in PCOS patients. Dysfunction can be treated which helps to manage infertility associated with PCOS.

(303) The Predictive Role of Baseline Hormone Profile Evaluation for the Likelihood of Having a Child in Infertile Men

Abstract Introduction Sex hormone profile evaluation is commonly used in male infertility assessment to identify potential hormonal imbalances and underlying issues that can impact sperm production, sperm quality, or reproductive organ function. Objective To evaluate the likelihood of having a child in subfertile and infertile men within five years based on their serum hormone levels on their initial encounter for infertility evaluation/treatment. Methods We identified a retrospective cohort from the Subfertility, Health, and Assisted Reproduction (SHARE) study (compiled 1996-2017) linked with familial information from the Utah Population Database (UPDB) including all men with a measured value of albumin, follicle-stimulating hormone (FSH), luteinizing hormone (LH), Free testosterone (T), total, and bioavailable T, sex hormone binding globulin (SHBG), and estradiol (E). We included men who had a semen analysis (SA) within 1 year of their hormone measurement. The primary outcome of the study was any evidence of childbirth, and the secondary outcome was the time from baseline hormone evaluation to childbirth. All men were followed for 60 months after their recorded hormone value for evidence of childbirth. Using Cox proportional hazards models, we modeled the likelihood of having a child and the time to childbirth (using linear regression) against the quintile of hormone distribution. Results A total number of 1298 men who underwent hormone profile evaluation and SA were included in this study. The mean age for the total cohort was 33 (29-37) years old. Men who had a child at the end of the study period (31 (28-36)) were significantly younger than men without a child at the end of the study with a mean age of (35.5 (32-40.25)) (p &amp;lt; 0.001). The mean sperm concentration for the total cohort was 7.6 (1-27.4) (M/ml) and the mean total progressive motile count was 9 (0.9-47) (M). Overall, semen parameters showed no significant differences between men who had a child at the end of the study follow-up versus men who did not. Our models showed that prolactin serum levels in quantile 7 have the highest ratio (2.236 (0.919-5.44) p=0.076) for the likelihood of having a child. Total testosterone in quantiles 3 and 5 showed an increased likelihood of having a child (2.119 (1.176-3.821) (p=0.012), (2.518 (1.412-4.491)) (p=0.002), respectively. Albumin in quantiles 5-9 followed a similar pattern with the highest ratio in quantile 8 (3.551 (1.486-8.487)) (p=0.004). Our results did not show meaningful patterns between semen parameters, serum hormone levels, and time to having a child. Conclusions The outcomes of this study indicate that prolactin, total testosterone, and albumin serum levels on the first visit in men with infertility concerns are associated with an increased likelihood of having a child. Abnormal semen analysis outcomes are not well associated with hypoandrogenism in infertile men. Our study shows that baseline serum prolactin, total testosterone, and albumin levels can be used to estimate the likelihood of having a child in subfertile and infertile men. These findings can provide the basis for further studies to determine an optimal screening method for male-factor infertility related to abnormal hormone levels.

Zinc oxide resveratrol nanoparticles ameliorate testicular dysfunction due to levofloxacin-induced oxidative stress in rats.

The present work is aimed to assess the protective influence of zinc oxide resveratrol nanoparticles against oxidative stress-associated testicular dysfunction. The number of 50 male albino rats were randomly separated into five groups (n = 10): Group I, control: rats gavage distilled water orally; Group II, Levofloxacin: rats that administered Levofloxacin (LFX) softened in distilled water at a dosage of 40mg/kg-1 BW orally every other day; Group III, Zn-RSV: rats administered with Zn-RSV (zinc oxide resveratrol in distilled water at a dose 20mg/kg-1 BW orally every other day; Group IV, (LFX + Zn-RSV): rats that were administered with Levofloxacin along with Zn-RSV nPs; Group V, Levofloxacin + Zn: rats were administered with Levofloxacin and Zno at a dose of 20mg/kg-1 BW orally every other day as mentioned before. This study lasted for 2months. Sera were collected to assess luteinizing hormone (LH), follicle-stimulating hormone (FSH), and testosterone values. Testicular tissues were utilized to evaluate levels of superoxide dismutase (SOD), nitric oxide (NO), malondialdehyde (MDA), and catalase (CAT). Semen samples were utilized to measure their quality (motility, concentration, and vitality). Histopathological and immune histochemical techniques investigated the morphological changes in the testis. Rats treated with Levofloxacin showed significantly lower levels of serum LH, testosterone, FSH, testicular enzymatic NO, catalase, SOD, BAX, and BCL-2 immune reactivity and sperm quality but significantly greater testicular malondialdehyde and caspase-3 immuno-reactivity Compared to both control and zinc oxide resveratrol treatment. Zinc oxide resveratrol nanoparticles ameliorated the harmful side effects of Levofloxacin. Improvements were more pronounced in the co-treatment (LFX + Zn-RSV) Zinc oxide resveratrol group than in the co-treatment (LFX + Zno) Zinc oxide group. Zinc oxide resveratrol nanoparticles could be a possible solution for levofloxacin oxidative stress-induced fertility problems.

Long-Term Protective Effects of Lamotrigine in a Rat Ovarian Ischemia-Reperfusion Model

Ovarium torsion is a gynecological emergency that is common in women of reproductive age and requires early diagnosis and intervention. In this study, we aimed to investigate the long-term anatomical, histological and biochemical protective effects of lamotrigine in ovariums in the ischemia – reperfusion (I–R) model created experimentally in rats. A total of 40 female Sprague-Dawley rats, 14 weeks old, weighing 220-270 grams were used in the study. The subjects were randomly distributed to form 4 groups named SHAM group, I - R group, I - R + Lamotrigine (LTG) group and R + LTG group. Under general anesthesia, the ovaries of the rats were reached and ischemia was created for 3hours with vascular clamps. 20mg / kg LTG was administered intraperitoneally (ip.) to group 3 30minutes before ischemia and to group 4 30minutes before reperfusion. At the third hour of ischemia, the vascular clamps were opened and the abdomen of the rats was closed according to the surgical procedure. The rats were followed up for 28 days postoperatively and the ovarium tissues taken on the 28th day were examined anatomically and histologically. Biochemically, estradiol (E2), follicle stimulating hormone (FSH) and antimullerian hormone (AMH) levels were measured from blood samples taken from their hearts. Granulosa cells with diffuse vaculations were observed in degenerative follicles in group I-R. Again in this group, severe hemorrhage, fibrosis and edematous areas were observed in the ovarium stroma (Ovarian Histopathological Scoring (OHS): 7). In the I - R + LTG group, OHS was statistically significantly lower than the I - R group (OHS: 2; p <0.000). In the R + LTG group, although the OHS score was calculated to be lower than the I - R group, there was no statistically significant difference (OHS: 6; p> 0.05). The protective effect of LTG against experimentally created ischemia and reperfusion damage was determined anatomically and histologically. No protective effect of LTG was observed in terms of FSH, E2 and AMH values measured from the blood sera of rats. These findings may provide a basis for future studies using LTG to treat ovarian ischemia-reperfusion injury.

The Importance of Discordant Follicle Stimulating Hormone and Inhibin B Levels in Primary Infertile Men: Findings from a Cross-Sectional Study.

We aimed to investigate the relationship between follicle stimulating hormone (FSH) and inhibin B (InhB). Data from 1,230 consecutive men presenting for primary couple's infertility were analyzed. Health-significant comorbidities were scored with Charlson comorbidity index. Quartiles of FSH and InhB were considered to determine threshold values. Descriptive statistics and logistic regression models tested association between FSH and InhB values. Overall, 1,080 (87.8%) men had concordant FSH and InhB values. Conversely, 150 patients (12.2%) had discrepancies in FSH and InhB, with 78 (6.3%) and 72 (5.9%) men reporting both low and high FSH and InhB values, respectively. Infertile men with discordant values were younger (median [interquartile range] 38.0 years [34-41 years] vs. 36.0 years [31-40 years]); had smaller testicular volume (TV) (12 mL [10-15 mL] vs. 15 mL [12-20 mL]); and, had more frequently a sperm DNA fragmentation test >30% (179 [59.1%] vs. 40 [78.4%]) than those with concordant values (all p<0.05). Moreover, a higher frequency of previous cryptorchidism (27.3% vs. 11.9%), lower sperm concentration (3.0 million/mL [0.9-11.0 million/mL] vs. 13.8 million/mL [3.1-36.0 million/mL]), lower progressive sperm motility rates (12.0% [5.0%-25.3%] vs. 20.0% [7.0%-36.0%]), and greater rates of non-obstructive azoospermia (36.4% vs. 23.9%) were found in men with discordant FSH and InhB values (all p≤0.005). At multivariable logistic regression analysis, higher body mass index (odds ratio [OR], 1.08; p=0.001), smaller TV (OR, 0.91; p<0.001), and a history of cryptorchidism (OR, 2.49; p<0.001) were associated with discordant FSH and InhB values. More than one out of ten infertile men had discordant FSH and InhB values in the real-life setting showing worse clinical profiles than those with concordant levels. Smaller TV and history of cryptorchidism could be used as clinical markers to better tailor the need to test InhB.

Effects of chronic exposure to soluble fractions of spent engine oil on the fertility of male Wistar rats

Objective: This study aimed to investigate the effects of chronic exposure to water-soluble fractions (WSFs) of spent engine oil (SEO) on male fertility in adult male rats. Materials and Methods: The study included 40 rats, which were randomized into 4 groups (n = 10) and treated for 45 days with different SEO concentrations. Group A (the control) received distilled water, while Groups B, C, and D were given 0.2 ml of 10%, 50%, and 100% concentrations of WSF of SEO, respectively, via oral gavage. Results: The study found no significant differences in the gonadometric indices, sperm motility, livability, and sperm concentration among the groups, except for slight changes in the weight and length of the testis and the mean diameter of both testes. However, the study found significant changes in the red blood cell, white blood cell, mean corpuscular hemoglobin, and neutrophil values following exposure to SEO. The mean values of testosterone, luteinizing hormone, and follicle-stimulating hormone did not show any significant alterations in the experimental groups compared to the control group. Conclusion: It was concluded that chronic exposure to SEO-soluble fractions can adversely affect the body’s physiological and biochemical processes, but it does not appear to have any significant effect on the fertility of male rats. However, further studies are needed to confirm these findings and to investigate the much longer-term effects of SEO exposure on male fertility.

Relationship between elevated serum decorin levels and acne vulgaris in women with PCOS.

The primary aim of this study was to investigate the serum levels of decorin, a small leucine-rich proteoglycan, in women diagnosed with polycystic ovary syndrome (PCOS) and concurrently presenting with moderate to severe acne vulgaris. Sixty patients with acne vulgaris symptoms, subsequently diagnosed with PCOS according to the revised Rotterdam criteria, were enrolled in the study. Acne severity was assessed using the acne global severity scale (AGSS), with patients fitting AGSS category 4 (moderate) and 5 (severe) grouped into two separate cohorts of 30 individuals each. The moderate acne group comprised patients with few inflammatory lesions and a minor nodule alongside predominantly non-inflammatory lesions, whereas the severe group contained patients with multiple nodules and a mix of non-inflammatory and inflammatory lesions. A control group of twenty healthy women without acne vulgaris or PCOS was also established. The study measured serum testosterone, follicle-stimulating hormone (FSH), Luteinizing Hormone (LH), and insulin levels, and calculated insulin resistance via the Homeostasis Model Assessment of Insulin Resistance (HOMA-IR) formula. Quantitative sandwich enzyme immunoassay was employed to determine decorin levels from venous blood samples. While age, body mass index (BMI), serum FSH, LH, testosterone, and HOMA-IR values demonstrated similarity between the moderate and severe acne cohorts, comparisons between the control and both acne groups (AGSS-4 and AGSS-5) revealed significantly elevated values in the latter, excluding age, BMI, and FSH. Importantly, the serum decorin levels in both acne groups were substantially higher than in controls. A significant positive correlation was observed between serum decorin levels and both HOMA-IR (r=7.88, p<0.01) and testosterone (r=0.813, p<0.01). This study suggests that elevated circulating decorin levels play a pivotal role in the manifestation of acne vulgaris in women with PCOS.

Pre-germ cell neoplasia in-situ in a patient with complete androgen insensitivity syndrome

Abstract Introduction/Objective Complete androgen insensitivity syndrome is a disorder of sex development in 46, XY individuals with external female genitalia and undescended testes, often presenting with inguinal hernia in infancy and/or primary amenorrhea in adolescents. Given the increased risk for the development of germ cell neoplasms in the ectopic testis, early gonadectomy or orchidopexy may be indicated. Methods/Case Report We report a 21-year-old patient assigned female at birth (46, XY) with a history of bilateral inguinal hernia repairs (age 2) and later with lack of menarche (age 16). Additional work-up showed an elevated testosterone level (394 ng/mL) and normal luteinizing and follicle stimulating hormone values. On pelvic ultrasound, retained intraabdominal gonads were identified, but female sex organs were absent. During a gonadal relocation procedure, the gonads appeared irregular in shape with multiple cysts and small nodules, and bilateral gonadectomy was performed. Grossly, the gonads measured 4.9 and 4.3 cm with a smooth external surface and a lobulated cut surface with multiple cysts, up to 1.6 cm, containing clear, serous fluid. Histologic sections showed most seminiferous tubules were lined only by Sertoli cells with only occasional spermatogonia. Leydig cell hyperplasia and areas of ovarian-like stroma were seen. OCT4 immunostain highlighted the nuclei of individually disposed germ cells in the base of tubules (singly dispersed, non-linear pattern), raising concern for germ-cell neoplasia in-situ (GCNIS). However, the histology and staining pattern were better interpreted as diagnostic of germ cells with delayed maturation and pre-GCNIS. Additionally, OCT4 showed rare single cells within the stroma and considered to represent residual undifferentiated gonadal tissue. After gonadectomy, the patient was started on hormone replacement therapy. Results (if a Case Study enter NA) NA Conclusion This case highlights the potential pitfalls in the interpretation of OCT4 immunostain to avoid misdiagnosis of germ cell neoplasia.

Re-assessment of the close relationship between serum FSH levels and semen quality: a retrospective cohort study of 11,929 Chinese men.

To establish a medically valuable normal reference interval of follicle-stimulating hormone (FSH) levels in males with normal semen and to assess the predictive value of FSH in males exhibiting semen abnormalities. The study involved male patients who underwent their initial serum sex hormone test and semen test between October 2013 and June 2023. The reference interval was identified as the 95% confidence interval (CI) of FSH values in the patients with normal semen parameters. Then, in the total study population, receiver operating characteristic (ROC) curves were performed to evaluate the discriminatory ability of FSH for oligozoospermia and non-obstructive azoospermia (NOA). Besides, multivariable logistic regression was performed to investigate the association of FSH with oligozoospermia and NOA adjusted by age. A total of 11,929 patients were finally enrolled in the study. The normal reference interval of FSH ranged from 1.70 IU/L to 7.60 IU/L (median: 3.98 IU/L) based on 4595 patients with normal semen routine parameters. In the total patients, ROC curves showed FSH to have a "fair" discriminatory ability for oligozoospermia (area under receiver operating characteristic curve (AUC) 0.747, threshold 7.32 IU/L, accuracy 0.734, positive predictive value (PPV) 0.754, negative predictive value (NPV) 0.726), while ROC curves showed FSH to have a "excellent" discriminatory ability for NOA (AUC: 0.921, threshold 10.18 IU/L, accuracy 0.903, PPV 0.593, NPV 0.972). Besides, multivariable logistic regression showed that FSH ≥ 7.32 IU/L was associated with a 8.51-fold increase in the risk of oligozoospermia adjusted by age, while FSH ≥ 10.18 IU/L was associated with a 38.93-fold increase in the risk of NOA. Our findings indicated that the reference interval for FSH in males with normal semen was 1.70-7.60 IU/L and found that FSH was capable of effectively discerning oligospermia and NOA.

Comparison of testosterone, FSH, LH and E2 hormone levels in infertility suspected males with COVID-19 infection.

Coronavirus disease 2019 (COVID-19) is an infectious disease that has many adverse impacts on many systems including reproduction. The direct effects of COVID-19 on urogenital system are still open to argue. This study aimed to compare testosterone, follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E2) hormone levels in COVID-19 infected male individuals with infertility suspicion. One hundred five control (healthy) and 105 COVID-19 infected males aged between 20 to 54 years old were enrolled in the study. All patients were either diagnosed with primary or secondary infertility suspicion. The COVID-19 infection was diagnosed via reverse-transcription polymerase chain reaction test. Blood samples from patients were analyzed from the control and COVID-19 group to measure serum testosterone, FSH, LH, and E2 levels. Hormone levels were statistically compared between groups with the Independent T test. In control and COVID-19 patients, no significance was determined for FSH and LH hormone values. Testosterone hormone were significantly decreased and E2 level was statistically increased in COVID-19 patients compared to that in the control group (P < .001). COVID-19 is a viral disease that affects organ including gonads. COVID-19 infection decreased testosterone levels and increased E2 levels, which leading to disorders in male and female reproductivity.

Does Platelet-Rich Plasma Treatment Increase In Vitro Fertilization (IVF) Success in the Infertile Population?

Platelet-rich plasma (PRP) is obtained by centrifuging the platelet-rich portion of the patient's own blood. The objective of our study is to retrospectively examine the impact of intraovarian PRP injection on infertile women with diminished ovarian reserve, specifically focusing on the oocyte count, oocyte quality, and endometrial thinning. A retrospective assessment was conducted on cases who had intraovarian PRP injection at the in vitro fertilization (IVF) unit of the Obstetrics and Gynecology Department of Gazi University School of Medicine hospital. The review encompasses the period from 1 January 2015 to 30 June 2020. The endometrial thickness, follicle count of greater than 14 millimeters, estradiol levels, follicle-stimulating hormone (FSH) levels, and antral follicle count were assessed during the menstrual cycle both prior to and within a period of 1-6 months following the PRP procedure. Twenty nonpregnant patients who had IVF before and 4-6 months after PRP were admitted to the post-PRP IVF cycle. The quantification of oocytes and M2 oocytes was conducted both prior to and subsequent to PRP treatment. Among 120 cases, only 60 cases who fulfilled inclusion criteria were analyzed.The basal endometrial thickness, basal follicle number (>14 mm), estradiol value, oocyte count, and M2 oocyte count exhibited a statistically significant increase following the administration of PRP injection (p<0.001). The basal FSH value exhibited a notable drop following the administration of PRP injection, with a statistically significant difference(p=0.002). In the pregnant group, the number of oocytes obtained with oocyte pick-up (OPU) increased by 300%, and in the nonpregnant group, the increase was 125% only. The number of M2 oocytes obtained with OPU increased by 250% in the pregnant group, while it was 93% in the nonpregnant group. Ultimately, the affordability of PRP production and its considerable theoretical efficacy have the potential to substantially decrease the expenses associated with assisted reproductive technology procedures. In the present scenario, the administration of an intraovarian PRP injection may be contemplated as a therapeutic intervention for women exhibiting diminished ovarian reserve.

Serum prolactin and gonadal hormones in hemodialysis women: a meta-analysis

BackgroundA meta-analysis followed by PRISMA 2020 statement was performed aiming to present a whole prolactin and sex hormone profile in hemodialysis women.MethodsLiteratures were searched in PubMed, Cochrane library, Embase, and Web of science before March 11, 2023. Trial sequential analysis (TSA) was performed to test the conclusiveness of this meta-analysis. Egger’s test and trim-and-fill analysis was used to test publication bias. We took standardized mean difference (SMD) as pool effect of hormones values including prolactin (PRL), follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2) and progesterone (P). This study was registered in PROSPERO and the number was CRD42023394503.ResultsTwenty-two articles from 13 countries were analyzed. Combining the results of TSA and meta-analysis, we found that compared with healthy control, hemodialysis women had higher PRL, follicular FSH and LH values and lower P levels (PRL: I2 = 87%, SMD 1.24, 95% CI: 0.79–1.69, p < 0.00001; FSH: I2 = 0%, SMD 0.34, 95% CI: 0.13–0.55, p = 0.002; LH: I2 = 39%, SMD 0.64, 95% CI: 0.34–0.93, p < 0.00001; P: I2 = 30%, SMD − 1.62, 95% CI: -2.04 to -1.20, p < 0.00001). What’s more, compared with women after renal transplantation, hemodialysis women had higher PRL levels (I2 = 0%, SMD 0.51, 95% CI: 0.25–0.78, p = 0.0001). There was not enough evidence to draw a conclusion on the comparison of hormones between regular and irregular menses hemodialysis women. Egger’s test and trim-and-fill analysis didn’t show significant publication bias.ConclusionsHemodialysis women had higher serum PRL, follicular phase FSH, LH and lower serum P values compared with healthy control. PRL values of hemodialysis women were also higher than that of women after renal transplantation.

The predictive effect of serum AMH and FSH levels alone or in combination on fertility outcome

Objective: To explore the roles of anti-mullerian hormone (AMH) and follicle stimulating hormone (FSH) in predicting clinical pregnancy. Materials and Methods: Forty patients who were decided on IVF/ICSI due to different infertility etiologies were included in the study. The patients were divided into two groups according to their AMH and FSH values as having a good prognosis or a poor prognosis. The clinical pregnancy and miscarriage rates of 33 cycles with good prognosis and 17 cycles with poor prognosis were compared. Results: In the good prognosis group, the FSH value was significantly lower than the poor prognosis group (5.98±1.04 mIU/mL vs. 13.6±3.07 mIU/mL, p&lt;0.01), while the serum AMH level was significantly higher. (3.80±1.32 ng/mL vs 0.54±0.02 ng/mL, p&lt;0.01). The rate of chemical pregnancy in the group with good prognosis was twice as high and significant compared to the group with poor prognosis (12 (36.3%) vs 5 (29.4%), p&lt;0.02). In terms of clinical pregnancy rates, the group with good prognosis showed a higher frequency (33.3% vs. 23.5%, p&lt;0.001), while miscarraige rates were higher in the group with poor prognosis (9.0% vs. 25%, p&lt;0.003). Conclusions: Evaluation of AMH and FSH together is critical in determining clinical pregnancy rates.

The effects of human amnion membrane-derived mesenchymal stem cells conditioned medium on ionizing radiation-induced premature ovarian failure and endoplasmic reticulum stress-related apoptosis mechanism

ObjectivesPremature ovarian failure (POF) is defined as the cessation of menstrual periods for at least 4–6 months before the age of 40 years, accompanied by FSH values measuring over 40 IU/L for a month. Radiation therapy, one of the cancer treatment methods, is known to accelerate ovarian aging by reducing and eliminating the number of primordial follicles in the ovarian follicle pool. Ionizing radiation has been reported to cause POF. The objective of this study is to investigate the impact of mesenchymal stem cell conditioned medium (hAMSCs-CM), which is isolated from the amniotic membrane of human placenta, on premature ovarian failure (POF) caused by whole-body irradiation. The study will focus on the ER stress and apoptosis mechanisms in the process. Study DisaynA POF model was created by exposing rats to 7 Gy of whole-body irradiation. Serum-free hAMSCs-CM were then administered via the tail vein. Follicle count was performed on the ovaries, and immunohistochemistry was used to determine the expressions of GRP78, CHOP, IRE-1, caspase-12, caspase-9, caspase-3. TUNEL was also carried out, and levels of serum FSH, LH, E2, AMH, and oxidative stress marker 8-OHdG were measured. Results and ConclusionThe application of hAMSCs-CM has been found to have a positive impact on follicles affected by radiation. After treatment, the number of primordial, primary, secondary, and graafian follicles, which had previously decreased due to radiation, showed an increase. Furthermore, the number of atretic follicles, which had been increasing due to radiation, showed a decrease. ER is one of the targets affected by ionizing radiation. After ionizing radiation, the expressions of ER stress-related markers and apoptosis markers increased in the ovary. After hAMSCs-CM administration, the expressions of these markers and number of TUNEL-positive cells decreased. Following irradiation, anti-mullerian hormone (AMH) and estradiol (E2) levels decreased, while follicle stimulating hormone (FSH) and luteinizing hormone (LH) levels increased. After administration of hAMSCs-CM, AMH and E2 levels increased, while FSH and LH levels decreased.Amnion membrane-derived mesenchymal stem cell conditioned medium can play a therapeutic role in ionizing radiation-induced premature ovarian failure by reducing endoplasmic reticulum stress and apoptosis.

Minipuberty assessment in newborns with hypoxic ischemic encephalopathy treated with therapeutic hypothermia: a single-center case-control study.

The aim of our single-center case-control study is to evaluate whether minipuberty occurs in patients with hypoxic ischemic encephalopathy (HIE) who underwent therapeutic hypothermia (TH). We intend to conduct this evaluation by confronting the values of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) and the values of testosterone in males and estradiol in females between newborns with HIE and in subsequent TH and healthy controls. We enrolled 40 patients (age: 56-179 days; 23 males), of whom 20 met the inclusion criteria for the case group and who underwent TH. A blood sample was taken from each patient at approximately 10 weeks of age to evaluate FSH and LH from the serum samples of all patients and to evaluate 17-beta estradiol (E2) and testosterone levels, respectively, from the serum samples of female and male patients. It was found that minipuberty occurred in the case group patients, with no significant differences reported from the control group and with hormonal serum levels comparable to healthy infants of the control group (FSH 4.14 mUI/ml ± 5.81 SD vs. 3.45 mUI/ml ± 3.48 SD; LH 1.41 mUI/ml ±1.29 SD vs. 2.04 mUI/ml ±1.76 SD; testosterone in males 0.79 ng/ml ± 0.43 SD vs. 0.56 ng/ml ± 0.43 SD; 17-beta estradiol in females 28.90 pg/ml ± 16.71 SD vs. 23.66 pg/ml ± 21.29 SD). The results of the present study may pave the way for further research and the evaluation of more possible advantages of TH.

Testicular Effect of Selenium Nanoparticles on Monosodium Glutamate Induced Alteration in Male Albino Rats.

&lt;b&gt;Background and Objective:&lt;/b&gt; The flavor enhancer Monosodium Glutamate (MSG) is mostly utilized in Asian and West African cuisines, especially in West African and Asian dishes. However, due to its availability, largely without labeling, in many food products, unintentional overuse of this food additive may occur. The objective of this study was to find out how selenium nanoparticles affected the toxicity of MSG in male albino rats' testicles. &lt;b&gt;Materials and Methods:&lt;/b&gt; As 35 Wistar male rats partitioned into 5 groups: G1: Control rats, G2: Received Se-NPs at 0.4 mg kg&lt;sup&gt;1&lt;/sup&gt; b.wt., orally, G3: Injected with MSG at a daily dose of 4 g kg&lt;sup&gt;1&lt;/sup&gt; b.wt., intraperitoneally (IP), G4: Ingested a daily oral dose of Se-NPs for 7 successive days and on the 7th day, received the first dose of MSG IP 4 g kg&lt;sup&gt;1&lt;/sup&gt; b.wt., then received both treatments till the end of the study and G5: Administered a daily oral dose of 4 g kg&lt;sup&gt;1&lt;/sup&gt; MSG, followed by Se-NPs at a daily dose of 0.4 mg kg&lt;sup&gt;1&lt;/sup&gt; b.wt., the experiment continued for 28 days. Serum testosterone hormone, Follicle Stimulating Hormone (FSH), Luteinizing Hormone (LH), the levels of serum lipid peroxidation (MDA), reduced Glutathione (GSH), Glutathione Peroxidase (GSH-Px), superoxide dismutase (SOD) and Lactate Dehydrogenase (LDH) were estimated and samples from testis were separated for histological analysis. &lt;b&gt;Results:&lt;/b&gt; The MSG treatment induced a significant decline in the values of serum testosterone, FSH, LH, GSH, GSH-Px and SOD. It also increased the values of serum MDA and LDH and spermatic arrest. While, the administration of Se-NPs orally before MSG treatment resulted in a decline in the values of serum MDA and LDH, an elevation in the values of serum GSH, GSH-PX and SOD, testosterone, FSH, LH and reappearance of sperm. &lt;b&gt;Conclusion:&lt;/b&gt; The use of Se-NPs as a protector exhibited more improvement in values of estimated hormones and oxidative stress markers than using it as a therapy.

Follicle-stimulating hormone and Inhibin B as predictors of successful sperm retrieval in men undergoing testicular sperm extraction: A review of 44 cases and meta-analysis.

The aim of the study and meta-analysis was to evaluate the predictive value of follicle-stimulating hormone (FSH) and inhibin B in sperm retrieval in men with non-obstructive azoospermia NOA. A total of 44 patients with a mean age of 36.1 years (SD=+/- 6.17) was included. We had 19 patients with successful sperm retrieval and 25 with failure. All patients had a normal karyotype. There was no difference between groups regarding patients mean age, prolactin or FSH. Patients with successful sperm retrieval had a significantly higher inhibin B level (134.62(+/-64,35) vs. 72.36(+/-67.78), p=0.006) and, paradoxically a higher body weight (92.38(+/-11.38) vs. 83.76(+/-11.90), p=0.027). The forest plots showed that a higher FSH level was significantly correlated with a negative success rate. Ahigher Inhibin B level was associated with a higher successful sperm retrieval (p=0.00001 respectively, p=0.0002). Surgical sperm retrieval could be, in some cases, the only chance to have a biological offspring.

Abstract #1375340: Correlation of Follicle Stimulating Hormone and Luteinizing Hormone Levels with HbA1c in Post-Menopausal Females

Menopause in female is a normal physiological process however, it is also a well-established risk factor for CVD and osteoporosis. Few studies suggest that low FSH is associated with adiposity and diabetes in post-menopausal women. Aim of this study was to explore correlations of follicle stimulating hormone (FSH) and luteinizing hormone (LH) levels with HbA1c level in post-menopausal females. The study was conducted at of Dr. S.N. Medical College, Jodhpur, India. Otherwise healthy postmenopausal women attending hospital for preventive health checkup were included in study. Postmenopausal status was confirmed by the absence of menses for at least 12 months. Known case of T2D/T1D, subjects on hormone replacement therapy, acutely sick were excluded from study. The baseline fasting blood samples were collected. Samples was assayed for FSH, LH, HbA1c and standard biochemical profile (glucose, lipid profile, Live function tests and renal function tests) using standard methods. The participants were classified as having diabetes or prediabetes using ADA criterias. Total 229 postmenopausal women were enrolled. Mean age of subjects was 63.2±9.9 years. Mean Hba1c was 6.2±1.4 gm% and subjects were further divided in to non-diabetes (68/229), prediabetes (104/229) and diabetes group (57/229) according to Hba1c levels. Mean LH was 25.8±15.6, FSH was 61.1±30.1 and LH/FSH ratio was 0.47±0.35. Mean LH was 31.4±15.8, 26.0±16.3, 19.5±12.6 in non-diabetes, prediabetes and diabetes group respectively. Mean FSH was 75.9±29.3, 59.6±27.6, 46.9±29.0 in non-diabetes, prediabetes and diabetes group respectively. The LH and FSH values in non-diabetes and diabetes group were statistically significant (p<0.01). In this study low FSH and LH levels were associated with higher level of HbA1c and increased risk of T2D.
