Overexpression of hsa-miR-30a-5p and nonobstructive azoospermia: A case-control study [PDF]
, 2022 Background: Some previous human and animal studies have supported the idea that KDM3A down-regulation might be the main cause of male infertility, especially in nonobstructive azoospermia (NOA).

MBOAT1 homozygous missense variant causes nonobstructive azoospermia
Asian Journal of Andrology, 2022 Nonobstructive azoospermia (NOA) is a common cause of infertility and is defined as the complete absence of sperm in ejaculation due to defective spermatogenesis. The aim of this study was to identify the genetic etiology of NOA in an infertile male from

Identification of pathogenic mutations from nonobstructive azoospermia patients
Biology of Reproduction, 2022 Abstract It is estimated that approximately 25% of nonobstructive azoospermia (NOA) cases are caused by single genetic anomalies, including chromosomal aberrations and gene mutations. The identification of these mutations in NOA patients has always been a research hot spot in the area of human infertility.

Surgical management of nonobstructive azoospermia [PDF]
, 2018 Nonobstructive azoospermia (NOA) is characterized by the complete absence of sperm in the ejaculate due to testicular failure. The evaluation and management of patients with NOA offer a challenge to the reproductive urologist.

Andrology, EarlyView.ABSTRACT Background Klinefelter syndrome (KS), typically characterized by a 47, XXY karyotype, is the most common sex chromosomal aneuploidy in males, with a prevalence of approximately one in 600–660 individuals. Despite its frequency, the syndrome remains significantly underdiagnosed, with 50%–75% of affected individuals never receiving a clinical ...
