Ultrasound evaluation of seminiferous tubules: a promising prognostic tool for men with nonobstructive azoospermia undergoing microsurgical testicular sperm extraction

Azoospermia, or the absence of spermatozoa in the semen, is present in up to 10% of men presenting with infertility. The majority of these men will have nonobstructive azoospermia (NOA), or impaired production of sperm. When present, testicular sperm can be used with in  vitro fertilization and intracytoplasmic sperm injection to achieve fertility. One of the most effective treatment options to obtain testicular sperm is microsurgical testicular sperm extraction (micro-TESE). Reported rates of successful sperm retrieval with micro-TESE range from 40% to 60%.
