Background: Vasectomy reversal (VR) is the only technique that allows men previously submitted to a vasectomy to conceive by natural pregnancy. We report our experience with microsurgical VR and identify predictive factors of natural pregnancy.

Methods: We retrospectively reviewed all patients submitted to VR by a single surgeon from 2008 to 2021 at our single center.

The vasectomy is a safe and effective method of contraception for men. Up to 6% of men who underwent vasectomy have a renewed child wish. Microsurgical vasectomy reversal (VR) in men, microsurgical epididymal sperm aspiration (MESA), or testicular sperm extraction (TESE) in men plus assisted reproductive technology (ART) in the female partner as well as the combination of VR and MESA/TESE plus ART represent established therapeutic strategies.

Although microsurgical vasoepididymostomy (MVE) is an effective treatment for epididymal obstructive azoospermia, some patients may experience delayed patency or suboptimal semen parameters after patency. However, research into patency time, semen quality postpatency, and associated influencing factors remains limited. This study aimed to address these issues by evaluating 181 patients who underwent at least one-sided MVE employing asingle-armed longitudinal intussusception vasoepididymostomy technique, with a follow-up period of over 12 months for 150 patients.

Background: In vasovasostomy (VV) surgery, the micro-surgical technique has consistently been shown to provide superior outcomes to both macroscopic and loupe-assisted techniques, with large studies showing overall patency rates of ~86% and pregnancy rates of ~52%. However, the question of whether a single- or double-layer anastomosis offers the best outcomes remains contentious, and despite the popularity of the two-layer technique, a meta-analysis suggests little difference in outcomes. This study records the outcomes of a single-surgeon series of a simplified single-layer technique, along with the comparative outcomes and predictive factors.

Background: Pediatric inguinal hernia repair (IHR) is a common cause of obstructive azoospermia (OA). Yet, the surgical treatment for this kind of OA remains difficult with poor fertility outcome.

Objectives: To evaluate the safety and effectiveness of totally extraperitoneal laparoscopy-assisted microsurgical vasovasostomy (VV) in the treatment of OA caused by pediatric bilateral IHR.
