Summary
Early surgical treatment for left varicocele in adolescents improved sperm motility and morphology compared to unoperated patients. This suggests adolescent varicocele surgery may benefit testicular development and fertility outcomes.
Area of Science:
- Urology
- Andrology
- Pediatric Surgery
Background:
- Varicocele is a common cause of male infertility.
- The optimal timing for varicocele treatment remains debated.
- Adolescent varicocele may impact future testicular function.
Purpose of the Study:
- To evaluate the effect of early surgical treatment for left varicocele on sperm parameters.
- To compare sperm parameters in surgically treated adolescents with healthy controls and unoperated varicocele patients.
Main Methods:
- Prospective follow-up of 19 adolescent males who underwent left varicocele surgery.
- Comparison of semen analysis results (sperm concentration, motility, morphology) with two age-matched control groups (healthy and unoperated varicocele patients).
- Andrologic examination and varicocele staging performed post-surgery.
Main Results:
- Surgically treated patients showed significantly higher sperm motility and morphology than unoperated patients.
- Sperm concentration was lower in the treated group compared to healthy controls but similar to unoperated patients.
- Testicular examination and semen analysis were conducted 2-8 years after surgery.
Conclusions:
- Adolescent varicocele surgery may positively influence sperm parameters, potentially due to testicular development during this period.
- Further large-scale, double-blind controlled trials are necessary to confirm efficacy and identify disease severity markers.
- Early intervention for left varicocele in adolescence shows promise for improving fertility outcomes.
