Abstract
BACKGROUND: Unwanted childlessness is a burden on a couple's relationship. The therapeutic spectrum of male infertility has increased significantly in recent years so that even azoospermia patients can be given biological paternity by testicular sperm extraction (TESE). OBJECTIVES: The indications, success rates, practical implementation, and possible complications of conventional and microscopic TESE in male infertility are presented in this review. METHODS: A nonsystematic search of the relevant literature was carried out. RESULTS: In obstructive azoospermia (OA), primarily desobstructive surgical procedures are used, while TESE is the surgical procedure of choice in nonobstructive azoospermia (NOA). In the latter, sperm extraction can be performed conventionally or microscopically (mTESE) assisted, whereby the latter offers an advantage in terms of sperm detection rate in the case of small testicular volumes (<12 ml), chemotherapy, Klinefelter's disease and AZFc microdeletions. The sperm detection rate of TESE is about 50%. Postoperative controls are useful because of the possible induction of symptomatic hypogonadism. CONCLUSION: Before performing TESE, determining the hormone status and human genetic clarification are necessary. Any costs incurred and the possibility of missing sperm proof must be discussed. Close cooperation between andrologists, gynecologists, reproductive physicians, and human geneticists is necessary. All in all, TESE is a safe surgical procedure with a low complication rate.
