Brief summary

The primary objective of this study is to determine if the use of frozen surgical testicular sperm specimens for ICSI lead to different IVF outcomes when compared with the use of fresh surgical testicular sperm for ICSI.

Detailed description

The study seeks to isolate the effect of slow freezing and thawing of surgical sperm specimens on fertilization and embryo blastulation rates by utilizing a randomized controlled split cohort protocol including men with obstructive azoospermia undergoing surgical sperm retrieval and good-prognosis female patients.

Interventions

OTHERSlow Freezing and Thawing

half of the surgically obtained testicular sperm will be frozen for 30 minutes and subsequently thawed prior to performing ICSI
