Testicular volume is a noninvasive predictor of sperm retrieval failure in idiopathic nonobstructive azoospermia [PDF]

Asian Journal of Andrology
We investigated the prognostic importance of noninvasive factors in predicting sperm retrieval failure in idiopathic nonobstructive azoospermia (iNOA). We studied 193 patients with nonobstructive azoospermia who underwent microsurgical testicular sperm ...

Variants in ZZS Complex-Associated Genes TEX11 and M1AP Are Responsible for Male Infertility and Nonobstructive Azoospermia. [PDF]

Andrology
ABSTRACT Background Nonobstructive azoospermia (NOA) is the most severe form of male infertility, with genetic factors contributing to approximately 30% of cases. However, only a small fraction of all NOA cases can be explained by the current genetic findings.

Development of a predictive model for increasing sperm retrieval success by microdissection testicular sperm extraction in patients with nonobstructive azoospermia

Asian Journal of Andrology, 2023
Microdissection testicular sperm extraction (micro-TESE) is widely used to treat nonobstructive azoospermia. However, a good prediction model is required to anticipate a successful sperm retrieval rate before performing micro-TESE.

Effect of varicocele repair on sperm retrieval rate and testicular histopathological patterns in men with nonobstructive azoospermia

Asian Journal of Andrology, 2022
Varicocele adversely affects semen parameters. However, the effect of varicocele repair on the sperm retrieval rate and testicular histopathological patterns in men with nonobstructive azoospermia has not been widely reported. We retrospectively assessed
