OBJECTIVES To compare, in a retrospective study, the ultrasound findings and hormonal changes after testicular sperm extraction (TESE) using the conventional multiple biopsy approach and the more recent microdissection technique. TESE has been performed using the conventional multiple biopsy approach and the more recent microdissection technique. METHODS A total of 435 men with nonobstructive...

Abstract Background We aimed to determine if the success of TESE and live-birth following TESE-ICSI can be predicted from readily available preoperative parameters for couples with azoospermia. Our methodology was as follows, this a cohort study who attended fertility service (from 2009-2019) at an NHS hospital in whom male partner diagnosed azoospermia required conventional multiple biopsies o...

PURPOSE To assess the impact of sperm retrieval on the gonadal function of rats with impaired spermatogenesis by comparing testicular sperm extraction (TESE) to aspiration (TESA). The efficacy of these procedures to sperm obtainment was also compared. MATERIALS AND METHODS A pilot study showed impaired spermatogenesis, but normal testosterone (T) production after a bilateral orchidopexy appli...

INTRODUCTION Congenital bilateral absence of vas deferens (CBAVD) is a non-treatable cause of obstructive azoospermia (OA). However, the affected men can father children by undergoing sperm retrieval (SR) and intracytoplasmic sperm injection (ICSI). MATERIALS AND METHODS This video describes percutaneous epididymal sperm aspiration (PESA), performed on a 36 year--old male with CBAVD. In PESA ...

OBJECTIVE To investigate the efficacy of IVF-intracytoplasmic sperm injection (ICSI) in patients who cryobanked semen before cancer treatment. DESIGN Retrospective consecutive study. SETTING University-based IVF unit. PATIENT(S) One hundred eighteen couples undergoing IVF-ICSI using pretreatment frozen sperm. INTERVENTION(S) Treatment follow-up. MAIN OUTCOME MEASURE(S) Semen parameter...

Conventional sperm freezing methods perform best when freezing sperm samples containing at least hundreds of spermatozoa. In this severe male factor infertility case series, we examined the reproductive outcomes in 12 intracytoplasmic sperm injection cases where spermatozoa used were frozen in Cell Sleepers. Cell Sleepers are novel devices in which individual spermatozoa can be frozen in microd...

Objective Improvement in sperm density and motility after varicocelectomy have been widely reported for men with oligoasthenoteratospermia (OAT),However the value of varicocelectomy in azoospermic men remain controversial.In this study we have evaluated the outcome of microsurgical varicocelectomy in nonobstructive azoospermic (NOA) men with clinical varicocele in five years in royan institute....
