Noninvasive parameters for predicating sperm retrieval rate (SRR) are desirables. Follicle-stimulating hormone (FSH) has been an important predictor since the first years of testicular sperm extraction. Recent studies showed continuous interests in FSH, with both pros and cons. Thus, we conducted a meta-analysis to evaluate the diagnostic value of FSH as a predictor for patients with nonobstruc...

Rainbow trout homogametic males, (XX or YY sex genotype), can be obtained, respectively, through masculinisation of genetic females or induced androgenesis. Aim of this study was to compare reproductive potential of neo-males (XX) and super-males (YY) with heterogametic males (XY). We measured spermatozoa motility parameters, sperm concentration, osmolality and characterized protein profiles in...

Background Although oncologic testicular sperm extraction (onco-TESE) has been increasingly practiced, the evidence of onco-TESE performed in patients with testicular cancer is insufficient. Furthermore, in bilateral testicular cancer, accounting for 0.5%-1% of testicular cancers, onco-TESE is more challenging and has been insufficiently reported. Case presentation Here we report the case of ...

Although the technique of intracytoplasmic sperm injection (ICSI) has been a revolution in the alleviation of male infertility, the use of testicular sperm for ICSI was a formerly unseen breakthrough in the treatment of the azoospermic man with primary testicular failure. At the clinical level, different procedures of testicular sperm retrieval (conventional TESE, micro-TESE, FNA/TESA, MESA, PE...

background: the aim of this study was to determine the incidence of azf (azoospermia factor) microdeletions of the y chromosome in infertile turkish male patients and intracytoplasmic sperm injection (icsi) outcome of these patients. objective: this study was undertaken in order to evaluate the outcome of intracytoplasmic sperm injection (icsi) in infertil man with azf microdeletions materials ...

Percutaneous epididymal sperm aspiration (PESA), percutaneous testicular sperm aspiration (TESA) and testicular sperm extraction (TESE) are invasive procedures and their consequences on the testis have not been clearly defined. In order to relate the sonographic and colour Doppler flow changes to the clinical data, 14 patients with non-obstructive and six with obstructive azoospermia were exami...
