[Treatment of azoospermia: surgical sperm retrieval (MESA, TESE, micro-TESE)].
The introduction of intracytoplasmic sperm injection (ICSI) into the spectrum of assisted reproductive technologies has offered men who suffer from severe disorders of spermatogenesis and azoospermia the possibility of fathering a child. Different surgical techniques can be used to extract spermatozoa from these men from either the epididymis and/or the testis. Surgical sperm retrieval offers a treatment for patients with testicular and/or obstructive azoospermia in cases where microsurgical refertilization is not an option or has already failed. Among surgical techniques that have been explored over the years, microsurgical epididymal sperm aspiration (MESA) and testicular sperm extraction (TESE) have become the most popular. Percutaneous techniques (such as TEFNA) are available but have disadvantages versus open surgical procedures. Together with cryopreservation of extracted spermatozoa, these techniques facilitate retrieval of spermatozoa for several ICSI attempts by a single surgical intervention.
