Adolescent microsurgical varicocelectomy and changes in sperm parameters: A matched cohort analysis

Abstract Background Varicocele, a common vascular abnormality surrounding the testis, is known to be associated with impaired semen parameters and male infertility in adults. However, its impact on the adolescent and young adult (AYA) population is less well known. Objectives The study aimed to assess the improvement in sperm parameters following varicocelectomy in the AYA population, comparing them to matched adult counterparts, and investigating potential advantages of early intervention. Methods A retrospective analysis was conducted using a comprehensive database at the University of Miami spanning from 2012 to 2023. We included AYA (under 25 years of age) men who underwent varicocelectomy. To ensure comparability, they were matched with adult patients (over 30 years of age) based on preoperative follicle‐stimulating hormone (FSH) values and varicocele grade in a 1:2 ratio. Semen parameters were evaluated before and after surgery, including sperm count, motility, morphology, and overall semen quality. Results We included 45 patients in the Adolescents and Young Adults (AYA) category, and matched them with 116 adults based on FSH and varicocele grade, all of whom underwent microsurgical varicocelectomy. The AYA group exhibited greater improvements post‐varicocelectomy compared to the matched cohort. Furthermore, postoperative sperm concentration in the AYA men demonstrated a remarkable increase, with a 1.7‐fold increase in mean concentration compared to the adult group ( p < 0.001). Additionally, motility also displayed significant enhancement among the AYA men, with a final mean total motile sperm count (TMSC) improvement of 2.25‐fold compared to the adult cohort ( p = 0.002). Discussion This study highlights the potential benefits of varicocelectomy as a viable treatment option for adolescents and young adults with varicocele, particularly those with impaired semen parameters. By intervening at an earlier stage of development, patients in this age group can achieve significant improvements in semen quality, as compared to their adult counterparts. Conclusion These findings underscore the importance of considering varicocelectomy as a valuable therapeutic approach for the younger demographic, potentially alleviating future fertility concerns.
