Summary

Varicocele is a common correctable cause of male infertility and may be associated with abnormal semen parameters, impaired testicular function, and scrotal discomfort. Microsurgical subinguinal varicocelectomy is a commonly used surgical approach because it allows careful preservation of the testicular artery, lymphatic channels, vas deferens, and vasal vessels under magnification. However, persistent or recurrent varicocele may still occur after surgery, possibly because of missed or persistent venous channels.

This randomized controlled trial will compare two surgical techniques in infertile men with clinically palpable varicocele and abnormal semen parameters. Participants will be randomly assigned to either microsurgical subinguinal varicocelectomy with selective extended venous stripping or standard microsurgical subinguinal varicocelectomy with conventional vein ligation and division.

The main purpose of the study is to determine whether selective extended venous stripping reduces the rate of clinically and Doppler-confirmed persistent or recurrent varicocele at 12 months after surgery compared with the standard microsurgical technique. The study will also compare semen parameter improvement, pain improvement in participants with baseline pain, pregnancy outcomes, operative time, postoperative complications, and the need for additional treatment during 12 months of follow-up.

  • Varicocele
  • Male Infertility

Interventions

PROCEDURE

Microsurgical Subinguinal Varicocelectomy With Selective Extended Venous Stripping

Microsurgical subinguinal varicocelectomy performed under magnification with preservation of the testicular artery, lymphatic channels, vas deferens, and vasal vessels. Favorable clinically relevant dilated veins will be dissected, mobilized, stripped over a defined segment, ligated, and divided. Veins not suitable for safe stripping will be treated by standard ligation and division.

PROCEDURE

Standard Microsurgical Subinguinal Varicocelectomy With Conventional Vein Ligation

Standard microsurgical subinguinal varicocelectomy performed under magnification. Identified veins requiring treatment will be isolated, ligated, and divided while preserving the testicular artery, lymphatic channels, vas deferens, and vasal vessels. Venous stripping will not be performed.
