Impact of age follicle stimulating hormone and Johnsens score on successful sperm retrieval by microdissection testicular sperm extraction

摘要

The spermatozoa retrieval rate achieved by microdissection testicular sperm extraction (TESE) for patients with non‐obstructive azoospermia is still approximately 50%, despite technical advances. Predicting a successful outcome is important to avoid unnecessary surgery. A study was conducted to determine a method for calculating the predicted probability of successful microdissection TESE.
