Effect of microsurgical varicocelectomy on fertility outcome and treatment plans of patients with severe oligozoospermia: An original report and meta-analysis.

Varicocele ligation has been proven to restore semen parameters and improve pregnancy rates in men with clinical disease. However, its effect in men with severe oligozoospermia (SO) is less clearly elucidated. This original report and meta-analysis examined the impact of subinguinal microsurgical varicocelectomy on semen parameters and fertility outcomes of men with SO. A retrospective chart review of 85 patients was conducted on patients with SO who underwent microsurgical subinguinal varicocelectomy. A literature search was carried out according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A total of 8 studies investigating the effects of varicocele ligation in men with SO were included for the meta-analysis. The original study reported significant improvements in semen parameters following surgery. 78 patients had a pre-operative TMSC < 5 million. Following surgery, 9 (11.5%) patients had a total motile sperm count (TMSC) between 5 and 9 million, while 14 (17.9%) patients had a TMSC > 9 million. Furthermore, the meta-analysis demonstrated a statistically significant increase in sperm count, total motility and TMSC following surgery. The reported natural pregnancy rate was 27.5%. Varicocelectomy does present as an important treatment option for SO patients because improvements in TMSC can broaden their fertility treatment options. © 2021 Wiley-VCH GmbH.
