Testicular sperm extraction (TESE) associated with intracytoplasmic sperm injection has allowed many men presenting non-obstructive azoospermia to achieve fatherhood. Microdissection TESE (microTESE) was proposed as a method to improve sperm retrieval rates in these patients; however, there have been failures. Little is known about whether microTESE leads to spermatogenic alterations in the con...

Introduction: We aimed to determine pregnancy and miscarriage rates following intracytoplasmic sperm injection (ICSI) cycles using retrieved epididymal and testicular sperm in azoospermic men and ejaculated sperm in oligospermic and normospermic men. Materials and Methods: This retrospective study was carried out on 517 couples who underwent ICSI. They included 96 couples with azoospermia and 4...

Leiomyomata of the urinary and male genital tract are extremely rare. They have been reported throughout the genitourinary male tract and the most common localization is the renal capsule. However, leiomyomas of the epididimis, spermatic cord, tunica albuginea and testis have been reported. We report diagnostic confirmation of a paratesticular leiomyoma in an azoospermic patient undergoing a te...

We performed this meta-analysis to evaluate the predictive value of different parameters in the sperm retrieval rate (SRR) of microdissection testicular sperm extraction (TESE) in patients with nonobstructive azoospermia (NOA). All relevant studies were searched in PubMed, Web of Science, EMBASE, Cochrane Library, and EBSCO. We chose three parameters to perform the meta-analysis: follicle-stimu...

We are thankful to Dr. Drobnis for her insights and balanced comments with regard to our article titled “comparison of sperm retrieval and reproductive outcome in azoospermic men with testicular failure and obstructive azoospermia treated for infertility”.1 Our main objective was to offer firm information that could be used as a counseling tool by doctors treating patients with azoospermia‐rela...

BACKGROUND Little is known about the extraction rate in repeated sperm retrieval procedures in azoospermic patients. This study aimed to assess the feasibility of repeated sperm recovery in these patients. METHODS A total of 1066 azoospermic men had their first sperm recovery between 1 January 1995 and 31 December 2003. A total of 381 men had obstructive azoospermia (OA), 628 nonobstructive a...

PURPOSE Testicular sperm extraction (TESE) for intracytoplasmic sperm injection (ICSI) was first introduced for the treatment of non-obstructive azoospermia. This study was conducted to detect predictive factors affecting the success of microTESE. MATERIALS AND METHODS We retrospectively evaluated the results of 191 cases who underwent microTESE. For each patient, the testicular volume, endoc...
