Outcome of microsurgical testicular sperm extraction in familial idiopathic nonobstructive azoospermia.

abstract：:The aim of this study was to investigate the predictive value of the parameters that might have an effect on the success of microscopic testicular sperm extraction (micro-TESE) in infertile patients with nonobstructive azoospermia (NOA). Between 2003 and 2014, 860 patients with NOA were retrospectively analysed. The e...
