简要总结
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.
详细描述
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.
