Results of intracytoplasmic sperm injection performed with sperm retrieved by microscopic testicular sperm extraction in azoospermic patients

摘要

ObjectiveThe absence of any sperm in the ejaculate is called azoospermia and it is detected in 1% of males and 10–15% of those with infertility complaints. Azoospermia may be due to obstructive (OA) and non-obstructive (NOA) causes. Today, healthy pregnancies can be achieved in azoospermic patients by intracytoplasmic sperm injection (ICSI) performed using sperm retrieved from microscopic testicular sperm extraction (m-TESE). In this study, we examined the sperm retrieval rates with m-TESE in azoospermic patients, the results of ICSI in OA and NOA patients with sperm and the underlying testicular pathologies in patients without sperm.
