Abstract
In a recent report [4], we have found that for unselected men with NOA, 9% or more of men with prior documented azoospermia can be found to have rare sperm in the ejaculate – obviating the need for planned surgery – if semen analysis is repeated on the day of sperm retrieval. Comparison of microdissection testicular sperm extraction, conventional testicular sperm extraction, and testicular sperm aspiration for nonobstructive azoospermia: a systematic review and meta-analysis. Successful Cryptozoospermia management with multiple semen specimen collection.
