Abstract

Introduction: Varicoceles account for the most common correctable cause of male infertility, with varicocele repair leading to improvements in semen quality. However, there is little evidence to establish the durability of varicocele repair. We analyzed the durability of improvements in postoperative semen parameters following microsurgical subinguinal varicocele repair. Methods: We evaluated all men who underwent microscopic subinguinal varicocelectomy from 2015-2019. Patients were included if they desired fertility and had a followup of at least 12 months. We assessed the baseline characteristics of these patients, as well as semen volume, total motile sperm count (TMSC), concentration, percent motility, and morphology. Semen parameters were analyzed at baseline (preoperative), approximately three months and ≥12 months postoperatively. Results: Of 105 men who underwent varicocelectomy, 18 men had a followup of at least 12 months. These men presented with median age 34.5 (27-38] years for a median followup duration of 14.5 (13-22.5) months. TMSC levels increased from 6.4 (1.1-24.5) million at baseline to 11.1 (2.4-38.4) million at approximately three months and remained similar at 12.5 (1.6-31.5) million at ≥12 months. The study is limited by its retrospective nature and limited sample size. Conclusions: Microscopic subinguinal varicocele repairs can result in durable improvements of semen quality beyond one year, as demonstrated by upgrade in median TMSC. Further studies should be performed to confirm our findings.
