Variants in ZZS Complex‐Associated Genes TEX11 and M1AP Are Responsible for Male Infertility and Nonobstructive Azoospermia

Andrology, Volume 14, Issue 6, Page 1847-1858, September 2026.
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.

Should men with idiopathic obstructive azoospermia be screened for genitourinary tuberculosis?

Journal of Human Reproductive Sciences, 2015
Objective: Infertility may be the sole manifestation of genitourinary tuberculosis (TB) and men with idiopathic obstructive azoospermia are often screened for TB using semen polymerase chain reaction (PCR) test. We assessed the benefits of such screening.

Can Hormonal Therapy Improve the Outcomes of mTESE in Patients With Non‐Obstructive Azoospermia?

Andrology, Volume 14, Issue 6, Page 1859-1872, September 2026.
ABSTRACT Background Non‐obstructive azoospermia (NOA) represents the most severe form of male infertility. Hypogonadism is common in NOA patients, and normal testosterone (T) levels are considered essential for spermatogenesis. Fertility‐preserving hormonal therapy (FpHT) has been proposed to optimize hormonal milieu and improve sperm retrieval rates ...

The outcome of ART in males with impaired spermatogenesis

Journal of Human Reproductive Sciences, 2008
Aims: This study was conducted to evaluate the outcomes of assisted reproductive technology (ART) procedures, viz., intrauterine insemination (IUI), in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) in males with impaired ...

Elevated LncRNA LINC00966 Suppresses PDE2A to Impair Sperm Motility in Asthenozoospermia

FASEB BioAdvances, Volume 8, Issue 8, August 2026.
This study identifies LINC00966 as an upregulated lncRNA in asthenozoospermia associated with reduced sperm quality. Linc00966 suppresses Pde2a, disrupts cGMP signaling, and promotes oxidative stress, thereby impairing spermatogenic cell viability and migration.

The frequency of follicle stimulating hormone receptor gene polymorphisms in Iranian infertile men with azoospermia

Iranian Journal of Reproductive Medicine, 2015
Background: Azoospermia is the medical condition of a man not having any measurable level of sperm in his semen. Follicle stimulating hormone (FSH) is a member of the glycoprotein hormone family that plays an important role in human reproduction because ...

Azoospermia, Atrophy, and Asymmetry: Unilateral Sertoli Cell Tumor as a Rare and Overlooked Cause of Male Infertility: A Case Report and Literature Review

Clinical Case Reports, Volume 14, Issue 7, July 2026.
ABSTRACT Sertoli cell tumors are uncommon sex‐cord stromal tumors making up < 2% of testicular tumors and have been reported to be associated with endocrine dysfunction that could compromise male fertility. Herein, we present a 34‐year‐old Pakistani male with primary infertility, azoospermia, enlargement of right testis, and contralateral severe ...

The management of obstructive azoospermia: a committee opinion [PDF]

Fertility and Sterility, 2019
Infertility due to obstructive azoospermia may be treated effectively by surgical reconstruction or by retrieval of sperm from the epididymis or testis, followed by in vitro fertilization with intracytoplasmic sperm injection. This replaces the ASRM documents titled "Sperm retrieval for obstructive azoospermia" and "The management of infertility due to
