Sperm retrieval for obstructive azoospermia
ثبت نشده
چکیده
Advances in the treatment of male infertility now routinely allow men with obstructive azoospermia to have fertility treatment without microsurgical reconstruction. A variety of methods for retrieving sperm from men with obstructive azoospermia have been described. The goals of sperm retrieval are to obtain the best quality sperm possible, to retrieve adequate numbers of sperm for immediate use and for cryopreservation, and to minimize damage to the reproductive tract.

Received on: April 28, 2009 – Accepted on: Oct 15, 2009 aBstRact Azoospermia is defined as the absence of mature spermatozoa in semen analysis after centrifugation. The causes of azoospermia may be related to spermatogenesis defects and classified as nonobstructive azoospermia, or to the obstruction of the efferent ducts of the genital tract and classified as obstructive azoospermia. Before the...

Testicular sperm retrieval techniques associated with intracytoplasmic sperm injection have changed the field of male infertility treatment and given many azoospermic men the chance to become biological fathers. Despite the current use of testicular sperm extraction, reliable clinical and laboratory prognostic factors of sperm recovery are still absent. The objective of this article was to revi...

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...

Obstructive azoospermia is a relatively common male infertility condition. The main etiologies of obstructive azoospermia include congenital, surgical-derived, traumatic and post-infectious cases. Although seminal tract reconstruction is a cost-effective treatment in most cases, this approach may not be feasible or desired in some cases. In such cases, assisted reproduction techniques offer a m...
