Article Abstract
Background: Following microsurgical vaso-epididymal anastomosis (VEA), anastomotic patency with sperm returning to the ejaculate is not always present and may even be delayed. The presence of motile spermatozoa is highly suggestive of future patency following surgery.
Aims: We prospectively analyse the factors that could predict motile spermatozoa at the epididymis intraoperatively and predictors of patency in patients with obstructive azoospermia (OA) undergoing microsurgical VEA.
Settings And Design: Department of Urology of a tertiary care centre in Northern India. It is a prospective observational study.
Materials And Methods: Over a 2-year period (July 2019 to June 2021), 26 patients with idiopathic OA were enrolled in the study. Twenty patients underwent microsurgical VEA. Patients were divided into two groups based on the presence/absence of intraoperative motile spermatozoa.
Statistical Analysis Used: Analysis of preoperative and intraoperative factors was done using the Mann-Whitney U-test, Chi-squared test and Fischer exact test.
Results: Out of 20 patients, 5 (group 2) had intraoperative motile spermatozoa in the epididymal fluid and 15 (group 1) had nonmotile spermatozoa. Low luteinising hormone (LH) levels ( = 0.01) and high testosterone levels ( = 0.05) were the predictive of presence of motile spermatozoa in epididymal fluid. Mean follow-up was 9 months (6-18 months). Predictors of higher patency were grade 2 epididymis (firm, turgid and tense) ( = 0.003), low LH levels ( = 0.03), low sertoli cell index ( = 0.006), high sperm-Sertoli index ( = 0.002) and better surgeon satisfaction ( = 0.01).
Conclusion: Low LH levels and high testosterone levels may be predictive of the presence of motile spermatozoa in epididymal fluid. Firm, turgid and tense epididymis, low Sertoli cell index, high sperm-Sertoli index and surgeon satisfaction suggest a greater chance of success after VEA for idiopathic azoospermia.

Characterising body and reproductive morphometry and their association with epididymal sperm quality can contribute to the conservation of sambar deer (Rusa unicolor). Five adult males maintained in captivity at the Getúlio Vargas Zoobotanical Park (Salvador, BA, Brazil) were captured, anaesthetised, and subjected to bilateral orchiectomy as part of a population-control strategy. Body measurements included head circumference, thoracic diameter, total length, withers height, and body weight.

The current study aimed to determine the impacts of hCG injection on the reproductive performance and hormonal profile of senile camels. Ten adult senile camels were classified into two groups: control males (n = 5) and treated males (n = 5; received hCG) once/week. Testicular morphology and echotexture [testicular volume (TV), testicular echogenicity (TE), and pixel heterogeneity (PH)] were measured.

Objective: To investigate the relationship among seminal oxidation-reduction potential (nORP), sperm DNA fragmentation (DFI) and semen parameters in patients with varicocele.
Methods: Clinical data of 522 patients treated in the reproductive andrology clinic of the Northern Theater General Hospital from November 2023 to December 2023 were retrospectively analyzed, including 435 men of childbearing age and 87 men of infertile age. The patients were divided into the varicocele group (n=116) and non-varicocele group (n=406) according to clinical diagnosis.

Objective: This study primarily aimed to investigate human papillomavirus (HPV) infection in males and to evaluate its effect on semen parameters, fertility and partner HPV infection status.
Methods: A total of 624 men who visited the West China Second Hospital of Sichuan University between October 1, 2019, and September 30, 2023, were included. HPV DNA was detected in exfoliated cells from the male genitalia using polymerase chain reaction (PCR) and reverse membrane hybridization to analyze the relationship between HPV infection and semen parameters.
