Limiting the number of injected oocytes to three impairs ICSI outcomes in patients with nonobstructive azoospermia.
BACKGROUND Since March 2004, only a maximum of three oocytes were allowed to be subjected to ICSI at one time in Italy. A previous study failed to show an impact of this restriction on fresh embryo transfer outcomes. The objective of this study was to compare ICSI outcomes before and after this restriction in patients with nonobstructive azoospermia. METHODS Patients underwent testicular sper...
متن کاملSperm retrieval rates and ICSI outcomes for men with nonobstructive azoospermia and the health of resulting offspring
In the article published in the Asian Journal of Andrology, Esteves et al.1 report on the results of a reasonably large (365) retrospective series of patients with nonobstructive azoospermia (NOA) who had sperm collected by microscopically assisted microdissection (microTESE) for intracytoplasmic sperm injection (ICSI). The results from NOA patients are compared with previously published data f...
متن کاملPrediction of successful sperm retrieval in patients with nonobstructive azoospermia.
INTRODUCTION Our aim was to evaluate the predictive values of factors that indicate successful sperm retrieval in men with nonobstructive azoospermia. MATERIALS AND METHODS We evaluated 85 infertile men with nonobstructive azoospermia who underwent multiple bilateral testicular biopsies. Factors including age, infertility period, surgical history, testicular volume, testicular consistency, se...
متن کاملVaricocele repair in patients with nonobstructive azoospermia: a meta-analysis.
PURPOSE Multiple small case series have reported sperm in the ejaculate and spontaneous pregnancies in patients with nonobstructive azoospermia after varicocele repair. We hypothesized that men with favorable testicular histopathology on testis biopsy such as maturation arrest or hypospermatogenesis would have a higher probability of success than those with more ablative pathology, eg Sertoli-c...
متن کاملControversies in the management of nonobstructive azoospermia.
The fertility potential of patients with nonobstructive azoospermia (NOA) depends on sperm extraction from the tissue sample and then in vitro fertilization with intracytoplasmic sperm injection (IVF/ICSI). Unfortunately, there is no consensus regarding predictors that can identify nonobstructive azoospermic men with a potentially high yield at the time of sperm extraction. This article analyze...
