We report the largest single-center experience with robotic-assisted microscopic varicocelectomy (RAMV) in male infertility. From August 2012 to February 2015, men with infertility of at least a year and varicoceles underwent RAMV by a single surgeon. Varicocele was diagnosed on physical examination and confirmed by ultrasound by a single ultrasonographer. Preoperative hormone panel, semen anal...

BACKGROUND To evaluate predictive factors of successful microdissection-testicular sperm extraction (MD-TESE) in patients with presumed Sertoli cell-only syndrome (SCOS). MATERIALS AND METHODS In this retrospective analysis, 874 men with non-obstructive azoospermia (NOA), among whom 148 individuals with diagnosis of SCOS in prior biopsy, underwent MD-TESE at Department of Andrology, Royan Ins...

Male infertility may occur due to obstructive and non-obstructive reasons, some pathologies be corrected with surgical medical treatment. Such treatment increase the possibility of spontaneous pregnancy, success assisted reproductive technology, also testicular sperm retrieval rate. This review will focus on alternatives in infertile males. Although options for varicocele men include open surgi...

The European catfish (Silurus glanis L., 1758) is an important species for the aquaculture sector and production of quality broodstock in artificial fertilization methods as well. One crucial steps determining success reproduction to obtain sufficient good-quality sperm. aim this study compare two different used sperm from catfish. first method surgery extraction testicular taking testicles (CS...

Testicular sperm extraction (TESE) may provide spermatozoa for attempts at fertility with assisted reproduction; however, the physiological effects of TESE on testicular function are not well understood. In order to evaluate the effects of TESE on the testis, 64 patients were evaluated after TESE for non-obstructive azoospermia with physical examinations, serial scrotal sonography, histological...

OBJECTIVE To assess the effects of two methods of freezing on testicular sperm DNA from subjects with obstructive azoospermia and to compare these with samples of fresh and freeze-thawed testicular sperm from fertile men. DESIGN The Comet assay was used to determine the percentage of undamaged DNA in fresh testicular sperm, testicular sperm freeze-thawed in suspension and in a biopsy sample (...

INTRODUCTION The aim of this study was to evaluate the effect of microsurgical subinguinal varicocelectomy on semen parameters in azoospermic men with clinical varicocele and to determine the predictive parameters of postoperative improvement. METHODS Twenty-three men with non-obstructive complete azoospermia and varicocele underwent subinguinal open microsurgical varicocele repair. The outco...

BACKGROUND The availability of testis specific genes will be of help in choosing the most promising biomarkers for the detection of testicular sperm retrieval in patients with non-obstructive azoospermia (NOA). Testis specific chromodomain protein Y 1 (CDY1) is a histone acetyltransferase which concentrates in the round spermatid nucleus, where histone hyperacetylation occurs and causes the rep...
