Obesity Is an Independent Risk Factor for Oligozoospermia, With Co‐Existing Hyperglycemia Exacerbating Risks of Asthenozoospermia and Elevated Sperm DNA Fragmentation

Andrology, EarlyView.
ABSTRACT Background Metabolic health plays a critical role in maintaining male fertility and may influence offspring health. Therefore, it is necessary to incorporate metabolic indicators into the clinical assessment of male fertility. However, the relationships between different metabolic abnormalities and semen quality remain incompletely understood.

Shorter Obstructive Intervals and Motile Sperm on Intraoperative Vasal Fluid Evaluation Predict Favorable Semen Parameters Following Vasovasostomy

Andrology, Volume 14, Issue 6, Page 1801-1808, September 2026.
ABSTRACT Background Vasectomy reversal is the primary method of fertility restoration for men who wish to pursue natural conception following vasectomy. The existing body of literature evaluating vasovasostomy (VV) success is primarily focused on endpoints that capture the presence or absence, rather than the quantity and quality, of sperm in ...

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.

Investigation of piwi-interacting RNA pathway genes role in idiopathic non-obstructive azoospermia [PDF]

, 2018
Genes involved in piwi-interacting RNAs (piRNAs) pathway have an essential role in spermatogenesis. HIWI and TDRD proteins are critical for piRNA biogenesis and function. Therefore, Mutations and polymorphisms in HIWI and TDRD genes may play role in male

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 ...
