[Testicular sperm extraction for non-obstructive azoospermia: results with conventional and microsurgical techniques].

چکیده
Testicular sperm extraction (TESE) was performed on patients with non-obstructive azoospermia using the conventional or microdissection technique. First, conventional TESE was attempted on all patients. If the sperm was retrieved successfully, the TESE procedure was terminated. Microdissection TESE was indicated only for patients for whom the conventional sperm retrieval was unsuccessful. Sperm was successfully retrieved with conventional TESE from four (24%) of 17 patients with non-obstructive azoospermia. The remaining 13 patients underwent microdissection TESE and sperm was successfully retrieved from four of them. Application of the microdissection technique resulted in an improvement in sperm retrieval rates from 24% with conventional TESE to 48% when combined with the microdissection technique. None of the patients showed any acute or chronic complications after TESE. Intracytoplasmic sperm injection (ICSI) was performed on five of the eight patients with successful sperm retrieval and the partner of four of these patients became pregnant and progressed to delivery. These results indicate the usefulness of microdissection for improving the sperm retrieval rate in men with non-obstructive azoospermia.

متن کاملPredictive factors of successful microdissection testicular sperm extraction
Azoospermia in men requires microsurgical reconstruction or a procedure for sperm retrieval with assisted reproduction to allow fertility. While the chance of successful retrieval of sperm in men with obstructive azoospermia approaches >90%, the chances of sperm retrieval in men with non-obstructive azoospermia (NOA) are not as high. Conventional procedures such as fine needle aspiration of the...
متن کاملLaboratory processing and intracytoplasmic sperm injection using epididymal and testicular spermatozoa: what can be done to improve outcomes?
There are two main reasons why sperm may be absent from semen. Obstructive azoospermia is the result of a blockage in the male reproductive tract; in this case, sperm are produced in the testicle but are trapped in the epididymis. Non-obstructive azoospermia is the result of severely impaired or non-existent sperm production. There are three different sperm-harvesting procedures that obstructiv...
