Father–Son Comparison of Reproductive Traits

Andrology, EarlyView.
ABSTRACT Background Little is known about the relative contribution of genetic and environmental factors on male reproductive function. Objectives We studied in a cross‐sectional setting, whether testicular function and genital size correlate in father–son pairs.

A no-stop mutation in MAGEB4 is a possible cause of rare X-linked azoospermia and oligozoospermia in a consanguineous Turkish family

Journal of Assisted Reproduction and Genetics, 2017
PurposeThe purpose of this study was to identify mutations that cause non-syndromic male infertility using whole exome sequencing of family cases.MethodsWe recruited a consanguineous Turkish family comprising nine siblings with male triplets; two of the ...

Comprehensive Quantification of Oligoasthenozoospermia Induced by Obesity, Reproductive Toxicants, and Their Combination in Rat Models

Andrology, Volume 14, Issue 6, Page 1535-1551, September 2026.
ABSTRACT Background Oligoasthenozoospermia is a leading cause of male infertility and has been increasingly associated with the global surge in obesity and exposure to reproductive toxicants. Despite extensive research on each factor individually, their combined pathological effects remain poorly understood.

Semen Quality in Transgender Individuals Seeking Fertility Preservation

Andrology, Volume 14, Issue 6, Page 1771-1776, September 2026.
ABSTRACT Background Transgender individuals assigned male at birth (AMAB) may choose to preserve their fertility prior to starting gender‐affirming hormone therapy (GAHT). However, limited data exist regarding the baseline reproductive and hormonal characteristics of this population before and after GAHT.

Serine Ameliorates Cadmium‐Induced Testicular Injury by Regulating the PGAM1/PHGDH Signaling Pathway

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 8, August 2026.
Serine mitigates cadmium‐induced testicular injury in mice by inhibiting the PGAM1/PHGDH pathway, restoring ion homeostasis and glycolysis, and relieving oxidative stress, inflammation, fibrosis, and apoptosis. ABSTRACT Cadmium (Cd) is a widespread environmental contaminant that impairs male reproductive function; however, the metabolic mechanisms ...

Y-chromosome microdeletions in nonobstructive azoospermia and severe oligozoospermia

Asian Journal of Andrology, 2016
The aim of the present work was to present the outcomes of the patients with Y-chromosome microdeletions treated by intracytoplasmic sperm injection (ICSI), either using fresh (TESE) or frozen-thawed (TESE-C) testicular sperm and ejaculated sperm (EJAC).

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.
