Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
laparoscopic varicocelectomy (standard urologic procedure in infertile patients with varicocele). Transperitoneal (3 trocars 10 mm; 10 mm; 5 mm) approach with ligation of spermatic left vein.
Participants will be observed for a follow-up period of 12 months after completion of surgery. The laparoscopic varicocelectomy surgical procedure takes approximately 30 minutes per participant
Intervention code [1] 285980 0
Treatment: Surgery
Comparator / control treatment
microsurgical subinguinal varicocelectomy (standard urologic procedure in infertile patients with varicocele). Subinguinal approach with ligation of all spermatic veins under 25 x microscopic magnification. Participants will be observed for a follow-up period of 12 months after completion of surgery. The microsurgical subinguinal varicocelectomy takes approximately 90 minutes per participant

Summary
Brief summary
This is a comperative study of two surgical interventions in infertile men with varicocele. Both interventions are widely accepted, but only retrospective studies proved their equivalence. In our opinion microsurgical intervention is superior both in terms of safety and efficacy. The only good comparison may be done in a prospective manner.
