Epigenetics of nonobstructive azoospermia [PDF]
Asian Journal of AndrologyNonobstructive azoospermia (NOA) is a severe and heterogeneous form of male factor infertility caused by dysfunction of spermatogenesis. Although various factors are well defined in the disruption of spermatogenesis, not all aspects due to the ...

Nonobstructive azoospermia: an etiologic review [PDF]
Asian Journal of AndrologyAzoospermia is the complete absence of spermatozoa in the ejaculate in two or more semen analyses after centrifugation. Nonobstructive azoospermia (NOA) represents the most severe form of male factor infertility accounting for 10%–15% of cases and stems ...

Differentiation between nonobstructive azoospermia and obstructive azoospermia: then and now [PDF]
Asian Journal of AndrologyMale infertility has seen an increase in prevalence with cases of azoospermia estimated to affect 10%–15% of infertile men. Confirmation of azoospermia subsequently necessitates an early causal differentiation between obstructive azoospermia (OA) and ...

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

Deciphering the Molecular Characteristics of Human Idiopathic Nonobstructive Azoospermia from the Perspective of Germ Cells [PDF]
Adv Sci (Weinh), 2023 Nonobstructive azoospermia (NOA) is one of the most important causes of male infertility, accounting for 10–15% of infertile men worldwide. Among these, more than 70% of cases are idiopathic NOA (iNOA), whose pathogenesis and molecular basis remain ...

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