Testicular sperm extraction combined with intracytoplasmic sperm injection in the treatment of men with persistent azoospermia postchemotherapy
Embryo Culture Techniques
Using TESE-ICSI, sperm retrieval leading to pregnancy and the delivery of healthy children is possible for men with long-standing azoospermia after chemotherapy. The prognosis for sperm retrieval was not influenced clearly by the chemotherapy regimen or the disease treated. Diagnostic biopsy also was of limited value in predicting the outcome of sperm retrieval. Despite prolonged nonobstructive azoospermia after undergoing chemotherapy, men no longer should be considered sterile in the era of advanced assisted reproductive techniques.
