Does the presence of blind-ended vas deferens and spermatic vessels in laparoscopic exploration of non-palpable testes conclusively indicate testicular absence?

The purpose of this study was to determine whether the presence of blind-ended vas deferens and spermatic vessels (VDSV) during laparoscopic exploration of non-palpable testes (NPT) indicates testicular absence or atrophy. A retrospective analysis was conducted on clinical data of patients diagnosed with NPT and treated with surgical intervention at our center from April 2013-April 2023. The dataset encompassed information such as the children's age, affected side, size of the contralateral testis, surgical procedures employed, outcomes, and histopathological examination results. All patients underwent physical examination and ultrasonography preoperatively, followed by a combination of laparoscopic exploration and exploration through inguinal or scrotal incisions during surgery. Long-term follow-up was conducted postoperatively. A total of 476 cases comprising 504 NPT were included in this study: 302 cases on the left side, 146 cases on the right side, and 28 cases bilaterally. All patients underwent surgical treatment within 6-126 months (median 13 months). During laparoscopic exploration, blind-ended VDSV were found in 90 testes (72 on the left side, 18 on the right side), while exploration through inguinal or scrotal incisions revealed 52 (57.8%) testicular nodules with atrophy, which were excised, leaving 38 (42.2%) without any findings. Histopathological examination of atrophic nodules revealed fibrosis as the most common finding in 41 cases (78.8%), followed by involvement of the vas deferens in 33 cases (63.5%), calcification in 24 cases (46.2%), epididymis in 23 cases (44.2%), and hemosiderin deposition in 7 cases (13.6%). Fibrosis, calcification, hemosiderin deposition, involvement of the vas deferens, and epididymis were found in combination in 47 specimens (90.4%). Seminiferous tubules (SNT) were found in 3 specimens (5.7%), and germ cells (GC) were found in 1 specimen (1.9%). The presence of blind-ended VDSV during laparoscopic exploration of NPT does not necessarily indicate testicular absence or disappearance. It is possible that atrophic testicular nodules are located within the inguinal canal or scrotum. This understanding contributes to the management of non-palpable testes. Considering their unpredictable malignant potential, we recommend excision.

Activation of SIRT1/Nrf2/HO-1 and Beclin-1/AMPK/mTOR autophagy pathways by eprosartan ameliorates testicular dysfunction induced by testicular torsion in rats

Testicular torsion carries the ominous prospect of inducing acute scrotal distress and the perilous consequence of testicular atrophy, necessitating immediate surgical intervention to reinstate vital testicular perfusion, notwithstanding the paradoxical detrimental impact of reperfusion. Although no drugs have secured approval for this urgent circumstance, antioxidants emerge as promising candidates. This study aspires to illustrate the influence of eprosartan, an AT1R antagonist, on testicular torsion in rats. Wistar albino rats were meticulously separated into five groups, (n = 6): sham group, eprosartan group, testicular torsion-detorsion (T/D) group, and two groups of T/D treated with two oral doses of eprosartan (30 or 60 mg/kg). Serum testosterone, sperm analysis and histopathological examination were done to evaluate spermatogenesis. Oxidative stress markers were assessed. Bax, BCL-2, SIRT1, Nrf2, HO-1 besides cleaved caspase-3 testicular contents were estimated using ELISA or qRT-PCR. As autophagy markers, SQSTM-1/p62, Beclin-1, mTOR and AMPK were investigated. Our findings highlight that eprosartan effectively improved serum testosterone levels, testicular weight, and sperm count/motility/viability, while mitigating histological irregularities and sperm abnormalities induced by T/D. This recovery in testicular function was underpinned by the activation of the cytoprotective SIRT1/Nrf2/HO-1 axis, which curtailed testicular oxidative stress, indicated by lowering the MDA content and increasing GSH content. In terms of apoptosis, eprosartan effectively countered apoptotic processes by decreasing cleaved caspase-3 content, suppressing Bax and stimulating Bcl-2 gene expression. Simultaneously, it reactivated impaired autophagy by increasing Beclin-1 expression, decreasing the expression of SQSTM-1/p62 and modulate the phosphorylation of AMPK and mTOR proteins. Eprosartan hold promise for managing testicular dysfunction arising from testicular torsion exerting antioxidant, pro-autophagic and anti-apoptotic effect via the activation of SIRT1/Nrf2/HO-1 as well as Beclin-1/AMPK/mTOR pathways.

Management of intraspecific aggression in two bull giraffes (Giraffa camelopardalis ssp. rothschildi).

Maintaining nonbreeding individuals in zoological collections may sometimes necessitate housing bachelor groups. In turn, intact cohabiting males may express increased intraspecific agonistic behaviors, and management intervention may be indicated. Where castration is deemed inappropriate (e.g., future breeding, or anesthesia and surgery-related risk), the immune contraceptive gonadotrophin-releasing hormone (GnRH) is increasingly used as an alternative. When intraspecific aggression (sparring) in two bull giraffes housed as a bachelor pair at Knowsley Safari, UK, escalated in frequency and intensity (despite management interventions), further mediation was warranted to moderate sparring behaviors. The Ex situ Program recommendation was for one giraffe, the (slightly) older, outwardly mature (darker, strong musth) individual, to be treated with the GnRH vaccine Improvac® (Zoetis). To gauge the efficacy of vaccination, behavioral observations were conducted during each vaccination phase to identify changes in the frequency of sparring behaviors. In addition, fecal samples were collected by keepers and sent to Chester Zoo's Endocrine Diagnostic Laboratory for analysis to compare androgen levels between the pre- and postvaccination phases. Testicular atrophy was investigated using both visual inspection and photographic images. The GnRH vaccine Improvac® initially appeared to be associated with reduced aggressive behaviors in the two bull giraffes. Sparring behaviors decreased in frequency after each vaccination phase, although these did not significantly diminish until phase 4. Physiological markers were inconclusive as testosterone concentrations varied throughout the phases, although levels remained low after the fourth vaccination phase. Approximately 8 months following the initial vaccination with Improvac®, the unvaccinated bull exhibited heightened aggression, resulting in physical aggression and injury to the vaccinated bull. As a result, both bulls are now on an Improvac® vaccination schedule, which has enabled them to remain housed together as a bachelor pair.

Outcomes from a new modified single needle laparoscopic percutaneous extraperitoneal closure and cut off for pediatric inguinal hernia

Inguinal hernia is a prevalent surgical condition in pediatric patients. Despite the efficacy of current treatment modalities, a certain recurrence rate still persists. Hence, our objective in this study is to introduce an innovative surgical technique designed to minimize surgical complications. We conducted a retrospective analysis on 809 pediatric cases that underwent laparoscopic repair with our innovative technique for inguinal hernia from June 2020 to June 2022. Demographic information, perioperative details, and postoperative follow-up outcomes were thoroughly assessed. All surgeries were conducted laparoscopically under general anesthesia. The procedure commenced by encircling the hernia sac with two sutures under laparoscopic guidance. Subsequently, the sac was exteriorized from the body using the two sutures, followed by ligation and excision of the hernia sac. The research findings demonstrate that the duration of unilateral and bilateral procedures was recorded as 15.9 ± 4.8 and 21.7 ± 3.9 min, respectively. Incision infection occurred in 7 patients (0.87%), and Male Complicated Inguinal Hernia (MCIH) was observed in 2 patients (0.23%). Notably, there were no occurrences of iatrogenic cryptorchidism, testicular atrophy, or recurrence (0%) during the follow-up period. In conclusion, our novel modification shows a notable reduction in postoperative recurrence rates and alleviates the impact of the procedure on the positioning of the testis or uterus. This modified technique is both safe and valuable, thus warranting broader adoption and promotion.

Clinical characteristics and outcome of children with acute cryptorchid testicular torsion: A single-center, retrospective case series study

BackgroundCryptorchidism and testicular torsion (TT) are relatively common conditions in clinical practice; however, sparse information about cryptorchid TT is available in the current literature. MethodsWe retrospectively reviewed the clinical characteristics, treatment modalities, and long-term outcomes of pediatric patients treated for acute cryptorchid TT. ResultsWe found eight patients with unilateral acute cryptorchid TT with a prevalence of 8.9% (8/90) among all TT cases. The left testis was affected in six patients. The median age of patients at the time of the surgery was 65 months (interquartile range (IQR) 4–136 months). The median duration of symptoms was 16 h (IQR 9–25 h), while the median time to treatment was 60 min (IQR 59–63 min). The most common symptoms were pain (abdominal and inguinal) and inguinal mass with no palpable testis in the ipsilateral hemiscrotum. Preoperative color Doppler ultrasonography revealed absent or decreased testicular blood flow in the affected testes in 7/8 of patients. Various degrees of testicular torsion (median 540°, min 360°, max 1260°) were found during surgery. A necrotic testis that led to orchidectomy was found in 4/8 of patients. The median follow-up period was 42.6 months (IQR 12.5–71.2 months), revealing only one patient with testicular atrophy. The final testicular salvage rate was 35%. ConclusionsGreater awareness among caregivers and primary care physicians about acute cryptorchid TT is required to improve their timely diagnosis and treatment. A physical examination of the external genitalia and inguinal regions should be mandatory to attain a proper diagnosis and treatment without delay.

The Male Reproductive Toxicity Caused by 2-Naphthylamine Was Related to Testicular Immunity Disorders.

2-naphthylamine (NAP) was classified as a group I carcinogen associated with bladder cancer. The daily exposure is mostly from cigarette and E-cigarette smoke. NAP can lead to testicular atrophy and interstitial tissue hyperplasia; however, the outcomes of NAP treatment on spermatogenesis and the associated mechanisms have not been reported. The study aimed to investigate the effect of NAP on spermatogenesis and sperm physiologic functions after being persistently exposed to NAP at 5, 20, and 40 mg/kg for 35 days. We found that sperm motility, progressive motility, sperm average path velocity, and straight-line velocity declined remarkably in the NAP (40 mg/kg) treated group, and the sperm deformation rate rose upon NAP administration. The testis immunity- and lipid metabolism-associated processes were enriched from RNA-sequence profiling. Plvap, Ccr7, Foxn1, Trim29, Sirpb1c, Cfd, and Lpar4 involved in testis immunity and Pnliprp1 that inhibit triglyceride and cholesterol absorption were confirmed to rise dramatically in the NAP-exposed group. The increased total cholesterol and CD68 levels were observed in the testis from the NAP-exposed group. Gpx5, serving as an antioxidant in sperm plasma, and Semg1, which contributes to sperm progressive motility, were both down-regulated. We concluded that the short-term exposure to NAP caused reproductive toxicity, primarily due to the inflammatory abnormality in the testis.

Comparison of Outcome of SAC Ligation Versus No SAC Ligation in Pediatric Patients Undergoing Inguinal Orchidopexy for Incompletely Descended Palpable Testes: A Randomized Control Trial

Background and Objective: The case of undescended Testis (UDT) is one of the most common condition presented to a pediatric surgeon. The standard procedure to rectify UDT is known as Orchidopexy. The main objective of this study is to examine and compare the results of orchidopexy surgeries conducted with or without sac ligation in palpable undescended testis of pediatric patients.Methods: This randomized controlled trial was done over a period of 12 months (July 2018 to July 2019) atthe Department of Pediatric Surgery, Children's Hospital & Institute of Child Health, Lahore. The selection of cases was made dependent upon fulfillment of departmental criteria and approval by ethical review committee. Consequently, 280 cases divided into two equal groups i.e. Group-A and Group-B (140 cases in each group) were shortlisted for the study after detailed scrutiny. The allotment of patient to above mentioned groups was randomized by lottery method. The patients in Group-A underwent orchidopexy with ligation of sac while the patients of Group-B were operated without sac ligated. The surgeries were performed under general anesthesia by consultant surgeons of same caliber and competence. Moreover, in order to quantify and analyze the results of surgeries parameters such as Mean Operative Time, Postoperative Manifestations and recurrence of UDT were recorded on proforma. Subsequently, SPSS version 25 statistical software was utilized for calculating the mean and standard deviation of numerical variables such as age and operative time. Additionally, the frequency and percentage of variables such as recurrent UDT were also calculated. Chi-square test was applied to recurrent UDT and development of inguinal hernia. It is highlighted that P-value ≤0.05 was taken as significant.Results: Among 140 patients of sac ligation group, 40.7% were 1-4 years old and among 140 patients of nosac ligation group, 42.9% were 1-4 years old. In sac ligation group, 60.0% patients had right undescended testis while in no sac ligation group, 67.1% patients had right undescended testis. In sac ligation group, the mean operative time was 37.81 + 8.82 minutes while in non-sac ligation group; the mean operative time was24.34 + 4.12 minutes. In sac ligation group, no patient had post-operative hernia while in non-sac ligation group, 1.4% patients had post-operative hernia (p=0.15). In sac ligation group, 1.4% patients had recurrent UDT while in non-sac ligation group, 2.1% patients had recurrence. (p= 0.65)Conclusion: Study concluded that non-sac ligation technique is more effective than sac ligation technique interms of operative time and should be preferred for patients by surgeons.Keywords: Orchidopexy, undescended testes, testicular atrophy, inguinal hernia, recurrence

The ball's in your court: Trends, causes, outcomes, and costs of patient transfer for pediatric testicular torsion

BackgroundThe transfer of pediatric patients with testicular torsion from community hospitals to pediatric centers can be a time and resource-intensive step toward emergent surgical intervention. ObjectiveWe sought to describe trends of patient transfer in our state and compare clinical outcomes and health system costs between patients transferred and treated primarily at a pediatric center. Study DesignThis retrospective cohort study compared patients aged 1-18 years who presented directly to a pediatric center to those transferred for acute testicular torsion from 2018-2023. Exclusion criteria included age <1 year, non-urgent surgery, and admission from clinic. Patient age, BMI, Tanner stage, ASA class, insurance coverage, and presentation time were covariates. Group characteristics and times from symptom onset to initial ED presentation to surgery were compared via two-sided Student’s t-tests. Clinical outcomes (orchiectomy, testicular atrophy) were compared via Fisher’s exact tests. Costs from transferring hospitals were estimated from costs at our institution, and medical transport costs were extrapolated from contract prices between transport agencies and the pediatric center to compare total episode-of-care cost. ResultsA total of 133 cases (37 primaries, 96 transfers) met inclusion criteria. Transfers increased over the study period (67% to 75%). There were no significant differences in age, Tanner stage, ASA score, BMI, or time of day of presentation between groups. Median transfer distance was 12 miles (IQR 7-22) and time was 1 hour (IQR 1-2). More than half of cases (53%) were transferred due to hospital policy regarding surgical treatment of minors, and 25% due to lack of urology coverage. Time from initial ED site to OR was nearly doubled for the transfer group (median 4.5 vs 2.5 hours, p=0.02). Despite a higher rate of orchiectomy in the primary group (43 vs 22%, p=0.01), this difference was not significant after stratification by symptom duration. The estimated average cost of care for patients transferred was twice that of primary patients ($15,082 vs $6,898). DiscussionTransfer of pediatric patients in our state for testicular torsion has increased in recent years. Hospital policies and local urology coverage are primary drivers of patient transfer which nearly doubled time to surgical intervention and more than doubled cost of care. Clinical outcomes were driven by delayed presentation. ConclusionTransfer of pediatric patients for testicular torsion nearly doubles time to surgical intervention and more than doubles cost of care. Restrictive hospital policies and gaps in rural hospital urology coverage present opportunities to improve the quality and efficiency of care for these children.

SURGICAL REPAIR FOLLOWING TRAUMATIC TESTICULAR RUPTURE : OUTCOME OF 3 CASES

Scrotal traumas are relatively uncommon. Most are blunt trauma caused by a direct blow to the scrotum. Early surgical exploration has considerably improved the prognosis of testicular trauma and reduced the rate of orchiectomy. Ultrasound has also improved the management of scrotal trauma. But there is controversy over the accuracy of ultrasound in predicting the presence or absence of testicular rupture. Its important to acknowledge the potential long-term repercussions such as testicular atrophy and infertility. We report three clinical cases, all young and victims of scrotal trauma with unilateral testicular rupture, all three of whom benefited from scrotal exploration with testicular preservation.

Undescended Testes Growth Potential in Relation to Testis Position from Diagnosis until Puberty.

Background: Testicular volume (TV) and testicular atrophy index (TAI) were used to determine criteria for normal, hypotrophic and atrophic undescended testes (UDT). Objectives: This study aimed to determine changes in TV and TAI in patients with different types of UDT. Materials and Methods: 182 boys (aged 0.3-14.0 years) with 212 UDTs were assessed twice 24 months apart. Testes were unilateral (UCT) or bilateral canalicular (BCT) and intra-abdominal (IAT). Results: At the beginning of the observation, the highest TAI was observed in IAT and the lowest in the BCT group (38.1 vs. 12.5%, p < 0.05). After 2 years, the highest TAI was observed in the BCT and IAT groups (20.5 and 19.1%), while the lowest was in the UCT group (12.0%, p < 0.05). At the beginning and after 2 years, the highest TAI was observed in boys aged < 6 years (25.0%, 18.2%) and the lowest in pubertal boys aged 12-14 years (5.9%, 7.3%, p < 0.05). A total of 78.3% of patients at the beginning and 86.8% at the end of the observation had TAI < 30%. Furthermore, 7% of boys at the beginning and 3% at the end of the observation had TAI > 50%. IATs have the highest testicular growth potential (TGP), while BCTs have the lowest (120.0 vs. 28.6%, p < 0.05). The highest TGP was in boys aged < 3 years (100%, p < 0.05) and boys aged 12-14 years (98.1%, p < 0.05), while the lowest was in boys aged 9-10.9 years (19.5%, p < 0.05). Conclusions: We revealed the continuous growth of UDTs until puberty independently of their position. IATs revealed high growth potential.

Stripping versus ligation of vas deferens in microscopic denervation of spermatic cord in men with chronic orchialgia: A multicenter study.

Microdenervation of the spermatic cord (MSCD) is an effective treatment modality for men with intractable scrotal content pain. For patients not interested in preserving fertility, some centers advocate ligation of the vas during denervation, while others prefer stripping of the vas deferens to preserve the vasal artery, hence preserving vasculature to the testis and possibly decreasing post-operative congestion pain. To compare outcomes of patients with chronic orchialgia, who underwent MSCD by either stripping or ligating the vas deferens. A retrospective chart review of 85 patients who underwent MSCD from 2017-2023 was performed. Patients' demographics including history of prior surgical procedures were recorded. Response to surgery was evaluated as either complete resolution of pain, partial resolution of pain, or no improvement in pain. Eighty-five patients underwent MSCD with a median (interquartile range, IQR) age of 36 (25.5-46.5) years and median duration of pain of 16 (6-31) months. Thirty-seven patients underwent stripping of vas, while 48 underwent ligation of vas during MSCD. Median follow up was 12 months. Twenty-one (43.5%) patients had prior inguinal scrotal surgery in the ligation group compared to 5 (13.5%) in the stripping group, p=0.003. The etiology of pain was similar between the groups. The response to MSCD between the two groups was similar, 67.6% of patients who underwent stripping had complete resolution of pain versus 66.7% of those who had ligation (p=0.968), with similar rates of post-operative complications (p-value=0.132). In men with intractable chronic scrotal content pain with no interest in preserving fertility, ligation, or stripping of the vas deferens yields similar outcomes with regard to pain resolution. Both techniques are safe with no reports of any testicular atrophy.

Comparison between staged laparoscopic technique in children with high intra-abdominal undescended testis: a systematic review and meta-analysis.

This study performed a systematic review and meta-analysis to compare the outcomes of the staged laparoscopic Fowler-Stephens Laparoscopic Orchiopexy (FSLO) and Staged Laparoscopic Traction Orchiopexy (SLTO) in patients with intra-abdominal testes (IAT). This study reviewed literature published from 2016 to 2024. A systematic literature search was conducted on three databases: PubMed, ScienceDirect, and Google Scholar, using keywords (High intra abdominal testis) AND (("Fowler Stephens laparoscopic orchiopexy" OR (FSLO)) OR (Staged Laparoscopic traction orchiopexy OR (SLTO)). Non-randomized trials and observational studies comparing staged laparoscopic FSLO and SLTO, without any time range restriction are included. Studies without FLSO orchidopexy as a control, case reports, case studies, duplicate publication, no full text and non-English studies are excluded. This study used the PRISMA protocol, the Jadad Scale, and the Newcastle Ottawa Scale (NOS) to evaluate the included studies. To analyze statistical data, the Review Manager (RevMan) software was used. The Chi-squared test was used to calculate statistical heterogeneity in the meta-analysis. There were 240 patients from 5 studies (109 in the SLTO group and 131 FSLO in group). The primary outcome of this study is testicular descent and atrophy. There were no significant differences in testicular descent (RR:1.08[0.96 - 1.23],p<0.20,I 2:0%) and atrophy rate (RR:0.45[0.19 - 1.09],p<0.08,I 2:0%). Secondary outcomes are the duration of operation in both the first and second stages. Statistical analysis reveals a significantly lower first-stage operation time in the FSLO group (MD:9.31[7.08,11.55], p<0.05;I 2:94%). At the same time, lower second-stage operation times are significantly reported in the SLTO group (MD:-4.05[-7.99,-0.12],p<0.05; I 2:60%). In terms of testicular descent and testicular atrophy the SLTO technique yields similar results to the FSLO technique. Both techniques have advantages and disadvantages, and we recommend SLTO as the first choice in children with a high IAT of <4 cm. CRD42023412407.

Therapeutic Potential of 4-Hexylresorcinol in Preserving Testicular Function in Streptozotocin-Induced Diabetic Rats.

It is known that many diabetic patients experience testicular atrophy. This study sought to investigate the effect of 4-hexylresorcinol (4HR) on testicular function in rats with streptozotocin (STZ)-induced diabetes, focusing on testicular weight, sperm motility, histological alterations, and serum testosterone levels to understand the efficacy of 4HR on testes. Our findings reveal that 4HR treatment significantly improves testicular health in diabetic rats. Notably, the STZ group exhibited a testicular weight of 1.22 ± 0.48 g, whereas the STZ/4HR group showed a significantly enhanced weight of 1.91 ± 0.26 g (p < 0.001), aligning closely with the control group's weight of 1.99 ± 0.17 g and the 4HR group's weight of 2.05 ± 0.24 g, indicating no significant difference between control and 4HR groups (p > 0.05). Furthermore, the STZ/4HR group demonstrated significantly improved sperm motility compared to the STZ group, with apoptotic indicators notably reduced in the STZ/4HR group relative to the STZ group (p < 0.05). These results underscore the therapeutic potential of 4HR for maintaining testicular function under diabetic conditions.

Gender affirming hormone therapy and transgender women fertility: Histologic predictors of germ cell presence.

Evaluate histological changes in testicular parameters after hormone treatment in transgender women. Cross-section study with patients who underwent gonadectomy at Hospital de Clínicas de Porto Alegre from 2011 to 2019. Hormone treatment type, route of administration, age at initiation and duration were recorded. Atrophy parameters were observed: testicular volume, tubular diameter, basal membrane length, presence of spermatogonia and spermatids (diploid and haploid spermatozoid precursors). Eighty-six patients were included. Duration of hormone treatment is associated with testicular atrophy and spermatogenesis arrest. Other characteristics of hormone treatment such as age of initiation, route of administration and type of treatment were not associated with testicular histological changes. Testicular volume may predict spermatogenesis arrest. Basal membrane length and tubular diameter ratio is an interesting predictor of germ cell presence. Cross-sex hormone treatment affects testicular germ cell presence. Basal membrane length and tubular diameter ratio reduces inter variability of measurements and better exemplify how atrophic seminiferous tubules are. Fertility preservation should be addressed by healthcare providers in order to recognize gender affirming treatment impact on transgender health.

Proteomic biomarkers in seminal plasma as predictors of reproductive potential in azoospermic men.

Azoospermia, characterized by an absence of sperm in the ejaculate, represents the most severe form of male infertility. While surgical sperm retrieval in obstructive azoospermia (OA) is successful in the majority of cases, patients with non-obstructive azoospermia (NOA) show retrieval rates of only about 50% and thus frequently have unnecessary surgery. Surgical intervention could be avoided if patients without preserved spermatogenesis are identified preoperatively. This prospective study aimed to discover biomarkers in seminal plasma that could be employed for a non-invasive differential diagnosis of OA/NOA in order to rationalize surgery recommendations and improve success rates. All patients signed written informed consent, underwent comprehensive andrological evaluation, received human genetics to exclude relevant pathologies, and patients with azoospermia underwent surgical sperm retrieval. Using label-free LC-MS/MS, we compared the proteomes of seminal plasma samples from fertile men (healthy controls (HC), n=8) and infertile men diagnosed with 1) OA (n=7), 2) NOA with successful sperm retrieval (mixed testicular atrophy (MTA), n=8), and 3) NOA without sperm retrieval (Sertoli cell-only phenotype (SCO), n=7). Relative abundance changes of two candidate markers of sperm retrieval, HSPA2 and LDHC, were confirmed by Western Blot. We found the protein expression levels of 42 proteins to be significantly down-regulated (p ≤ 0.05) in seminal plasma from SCO NOA patients relative to HC whereas only one protein was down-regulated in seminal plasma from MTA patients. Analysis of tissue and cell expression suggested that the testis-specific proteins LDHC, PGK2, DPEP3, and germ-cell enriched heat-shock proteins HSPA2 and HSPA4L are promising biomarkers of spermatogenic function. Western blotting revealed a significantly lower abundance of LDHC and HSPA2 in the seminal plasma of men with NOA (SCO and MTA) compared to controls. The results indicate that certain testis-specific proteins when measured in seminal plasma, could serve as indicators of the presence of sperm in the testis and predict the success of sperm retrieval. Used in conjunction with conventional clinical assessments, these proteomic biomarkers may assist in the non-invasive diagnosis of idiopathic male infertility.

Follow‐up results regarding fixation of contralateral testis after testicular torsion in children

AbstractThe aim is to investigate the possible advantages and disadvantages of contralateral testicular fixation (CTF) for boys with testicular torsion (TT) by long‐term clinical follow‐up results. A retrospective cohort study was conducted on TT boys at Children’s Hospital of Chongqing Medical University from September 2005 to December 2020. The baseline characteristics, intraoperative findings, and clinical follow‐up results were compared between TT patients underwent orchiopexy with or without CTF, and orchiectomy with or without CTF, respectively. The χ2 test and the Fisher’s Exact test were used to compare dichotomous outcomes, and the Mann‐Whitney U test was used to compare continuous outcomes without normal distribution. A total of 140 cases were included in this study. The bell clapper deformity was found in 30.4% of all torsed testes underwent orchiopexy, 16.4% during contralateral testicular exploration, and only 10.9% in bilateral sides. Contralateral testicular volume, adverse events, and paternity rates were comparable between patients underwent orchiopexy with or without CTF, and no subsequent contralateral TT observed during follow‐up. However, those patients underwent orchiectomy without CTF had more incidence of scrotal discomfort than those had orchiectomy with CTF (P = 0.027). In addition, one boy suffered subsequent contralateral TT after orchiectomy without CTF. The incidence of bell clapper deformity was lower in this research than that of literature reports. CTF would not induce testicular volume loss, atrophy or scrotal pain. Contralateral testicular discomfort and even subsequent TT could be more easily observed during follow‐up in patients without CTF. We still recommend routine surgical fixation of contralateral testicle during surgery.

Retrospective analysis of laparoscopic and open orchidopexy for non palpable intra-abdominal testes in a tertiary care centre

Purpose: Patients with non-palpable testes has numerous treatment options, the most effective treatment is still controversial. Laparoscopy has nowadays gained the trust as the most reliable modality for the management of impalpable testis. The aim of our study was to retrospectively analyse the laparoscopic and open orchidopexy procedures and report the outcome of our series. Material and methods: 120 patients with 130 non palpable testes with a mean age of patients about 2.7 years who had undergone orchidopexy by open and laparoscopic methods over past 8 years. Results: Mean age of open group was similar to laparoscopic group (2.7 ± 1.7 vs 2.5 ± 1.5 years; p &gt; 0.05). 10 patients (8.33%) presented with bilateral non palpable testes. 10 testes from the open group and 8 from the laparoscopic group were of vanishing variety. Fowler -Stephens staged procedure was done for 4 testes in laparoscopic group. The mean operative time was more in the laparoscopic group than the open (63min vs 47min). Laparoscopic orchidopexy group had generally lesser use of analgesics. The mean hospital stay between the open and laparoscopic groups was 2.1 vs 1.3 days (p &lt;0.05). 12 cases of testicular atrophy were noted, 7 from the open group and 5 from the laparoscopic group. Conclusion: Results of open and laparoscopic orchidopexy procedures were fairly constant. Although, laparoscopy gives significantly less morbidity, is less painful, has lesser hospital stay and is cosmetically better. Keywords: cryptorchidism; laparoscopy; orchidopexy; testis

The Safety and Effectiveness of Single-Stage, Vessel-Preserving, Laparoscopic Orchiopexy for Intra-Abdominal Testes in Pediatric Patients: A 10-Year Single-Center Experience.

Objectives: Intra-abdominal testes are located in a variety of intra-abdominal positions, most less than 2 cm from the internal ring. Various surgical techniques of laparoscopic orchiopexy have been described to date. The aim of this study was to evaluate the safety and long-term efficacy of a single-stage, vessel-preserving, laparoscopic orchiopexy for intra-abdominal testes in pediatric patients. Methods: A retrospective search of the medical records of 32 children (34 testes) who underwent single-stage, vessel preserving, laparoscopic orchiopexy for intra-abdominal testes between 1 January 2014 and 31 December 2023 was performed. Single-stage laparoscopic orchiopexies were performed in all patients for whom sufficient length of the spermatic cord was achieved during the procedure. The volume of each patient's testes was measured using ultrasound before and 6 months after laparoscopic orchiopexy. The main outcome of this study was testicular volume before and after the procedure. The secondary outcomes were the occurrence of early and late complications, the duration of surgery, and the length of hospital stay. Results: The median age at the time of surgery was 10 months (interquartile range-IQR 9, 13). The majority of the children (n = 24; 75%) were less than 12 months old at the time of surgery. A normal testis was found in 24 patients (70.6%), while a hypotrophic testis was visible in 10 cases (29.4%). The majority of the testes were located near the internal ring (n = 19; 55.9%), while in the remaining cases, the testes were located near the iliac blood vessels. The median duration of the surgical procedure was 37.5 min (IQR 33, 42.5). The duration of hospitalization was one day for all the children. No intraoperative complications were observed. One child had a wound infection at the site of the umbilical trocar, which was treated conservatively. In two cases (5.5%), testicular atrophy was detected during long-term follow-up. In three cases, the testis was found in a higher position in the scrotum during the follow-up period, but in two cases, the position was normal during the follow-up period, while in one case, the position in the scrotum remained unchanged. At long-term follow-up with a median of 35 months (IQR 19, 60.5), the overall success rate was 94.5%. The median testicular volume at 6-month follow-up increased from 0.31 mL (IQR 0.28, 0.43) to 0.40 mL (IQR 0.33, 0.53) (p = 0.017). Conclusions: Single-stage, vessel-preserving, laparoscopic orchiopexies for intra-abdominal testes are safe and effective in pediatric patients in whom adequate spermatic cord length can be achieved during the procedure.

Evaluation of histopathological patterns and testicular biopsies in infertile male and its relationship with some hormones in Kirkuk/Iraq

Infertility affects between 15% to 20% of couples worldwide, making it a major concern. Testing abnormalities may result in non-obstructive, permanent azoospermia. Infertility affects between 15% to 20% of couples worldwide, making it a common cause for worry. Testing abnormalities may result in non-obstructive, permanent azoospermia. Testicular biopsy is the only procedure available for diagnosing azoospermia. The current study included a cohort of 30 people who had been clinically diagnosed with azoospermia. Additionally, a cohort of 20 healthy male volunteers was enlisted from Kirkuk, Iraq's private laboratories and recruited from Azadi Teaching Hospital. The findings of this study indicate that Sertoli-cell-only-syndrome (39.996%) displayed the highest prevalence in testicular biopsies and it categorized Johnson score2, Testicular atrophy emerged as the second most frequently encountered condition (23.331%) it categorized as the Johnson scoring 1. Followed by germ cell maturation arrest (16.665%) as Johnson score8-3, followed by hypospermatogenesis (9.999%) as Johnson scoring 7, followed by Seminiferous tubule hyalinization (6.666%) as Johnson scoring 1, Subsequently, there was an observed occurrence of normal spermatogenesis, amounting to 3.333%. The study's results indicated that within our particular geographic region, the Sertoli-cell-only syndrome (SCOS) exhibited the highest prevalence among the 30 specimens examined, which were testicular biopsies obtained from infertile males. Furthermore, it was observed that individuals diagnosed with azoospermia showed a statistically significant increase in serum luteinizing hormone levels, while experiencing a statistically significant decrease in testosterone levels.

Testicular Vascularization after Pediatric Inguinal Hernia Repair: A Systematic Review and Meta-Analysis.

The effect of pediatric inguinal hernia repair (IHR) on testicular vascularization remains unclear. Manipulating the spermatic cord during surgery may reduce blood flow due to edema and vasoconstriction. This can lead to testicular atrophy. The study aims to review current knowledge of testicular vascular impairment following IHR in children. A systematic literature search was conducted in PubMed/Medline, Embase, Cochrane Library, and Web of Science. Methodological quality was assessed using validated tools. Data were extracted, and a pooled data analysis was performed. Ten studies were included in the systematic review. Six of these studies were eligible for meta-analysis. This revealed a significant decrease in testicular vascularization during the short-term follow-up (1 day-1 week) after IHR using the open surgical approach. This decrease was not present after laparoscopic intervention. There was no more increased resistance in the vessels at long-term follow-up (1 month-6 months), suggesting that the impaired vascularity is only temporary. There seems to be a short-term transient vascular impairment of the testis after open IHR in children. This might be of clinical relevance to prefer the laparoscopic approach for IHR in children, even though the open approach is the gold standard, in contrast to adult IHR. The impact on testicular function and sperm quality later in life remains unclear. Comparative studies of both techniques are needed to determine if there is a significant difference in testicular vascularity. Long-term studies are necessary to assess the impact of transiently reduced vascularity on sperm quality and fertility later in life.
