Sperm retrieval for obstructive azoospermia
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...
متن کاملSerum inhibin B determination is predictive of successful testicular sperm extraction in men with non-obstructive azoospermia.
Recent work indicates that serum inhibin B is a useful marker of spermatogenesis and inhibin B production sufficient to maintain detectable serum concentrations in adults depends on spermatogenic activity. The purpose of the present study was to investigate the usefulness of serum inhibin B measurement to predict the success of testicular sperm extraction (TESE) in 17 men with nonobstructive az...
متن کاملPredictive factors of successful sperm retrieval in azoospermia.
INTRODUCTION Testicular sperm extraction with intracytoplasmic sperm injection is the standard treatment for azoospermia. The objective of this study is to identify predictive factors of successful sperm retrieval. MATERIALS AND METHODS Between June 2003 and May 2011, we tried testicular sperm extraction (TESE) in 74 azoospermic patients in the Reproductive Medicine Unit of Son Espases Hospit...
متن کاملHIWI2 rs508485 Polymorphism Is Associated with Non-obstructive Azoospermia in Iranian Patients
Background: The PIWI-interacting RNA (piRNA) pathway has an essential role in transposon silencing, meiosis progression, spermatogenesis, and germline maintenance. HIWI genes are critical for piRNA biogenesis and function. Therefore, polymorphisms in HIWI genes contribute to spermatogenesis defects and can be considered as risk factors for male infertility. The aim of the present study was to i...
متن کاملPrognostic factors for sperm retrieval in non-obstructive azoospermia
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...
