Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To evaluate the benefits of laparoscopic Doppler ultrasound (LDU) assisted laparoscopic varicocelectomy (LV) and compare the surgical outcomes and complications between LDU assisted LV (LDU-LV) and microscopic subinguinal varicocelectomy for infertile patients with varicoceles.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

To compare the surgical outcomes such as semen parameters and the pregnancy rate and complications like postoperative varicocele recurrence and hydrocele between laparoscopic Doppler ultrasound assisted laparoscopic varicocelectomy and conventional microscopic subinguinal for infertile patients with varicoceles. To examine the microanatomy of the spermatic cord within suprainguinal portion.
