Purpose: We aimed to investigate possible hormonal changes following microdissection testicular sperm extraction (mTESE) in men with non-obstructive azoospermia (NOA) across three referral centers.
Materials And Methods: We prospectively analyzed data from 102 consecutive NOA men. Patients with prior hormonal therapies were excluded.

This study focused on continuous monitoring of the immunocontraceptive effect of Improvac® vaccine on the sexual activity of male goats determined by measuring plasma testosterone levels, testicular biometric and ejaculate examination. The animals in the experimental group (n=12) were administered two doses of 2 ml of Improvac® at a four-week interval; the animals in the control group (n=5) received 2 ml of saline. Blood collection, semen collection and testicular measurements were performed at 14-day intervals.

Objective: To evaluate outcomes of onco-testis sperm extraction (TESE) and to define potential predictors of successful surgical sperm retrieval (SSR).
Methods: For this study, we examined all men (i) diagnosed with a testicular mass, (ii) who had azoospermia, and (iii) who underwent a radical orchiectomy and onco-TESE. Our institutional database of testicular cancer (TCA) patients was reviewed.

Introduction: In this study, we aimed to explore whether a Y chromosome microdeletion (YCM) confers adverse effects on surgical sperm retrieval potential and intracytoplasmic sperm injection (ICSI) outcomes in men with azoospermia and severe oligospermia.
Methods: This was a retrospective cohort study, which included infertile men with azoospermia or severe oligospermia who were evaluated for karyotype analysis and YCM testing at a university-affiliated hospital between 2010 and 2022. Outcomes of microdissection testicular sperm extraction (mTESE) for surgical sperm retrieval were compared between men diagnosed with YCM and the control group in which no YCM were found.

Cryptorchidism is a common cause of male infertility, often necessitating microdissection testicular sperm extraction (m-TESE) for sperm retrieval post-surgery. However, uncertainties persist regarding m-TESE outcomes and influencing factors following cryptorchidism surgery. A systematic review and meta-analysis were conducted to evaluate sperm retrieval rates (SRR) among patients undergoing m-TESE after cryptorchidism surgery.
