PFOA exposure decreases acrosome reaction and increases DNA oxidative damage by impairing the sperm head shaping in mice

open access: yesEcotoxicology and Environmental Safety
Perfluorooctanoic acid (PFOA) is a reproductive toxicant, but its effects on sperm head shaping and acrosome reaction remain unknown. Adult male Bal b/c mice were given 0, 2 or 10 mg/kg/day of PFOA for 6 weeks by gavage. Elevated sperm head malformations

Testis‐Enriched F‐Box Protein FBXO39 Is Important for Spermiogenesis and Male Fertility in Mice

open access: yesAndrology, EarlyView.
ABSTRACT Background The SCF (Skp–Cullin–F‐box) complex is a major class of E3 ubiquitin ligases. F‐box proteins constitute the SCF complex and play a critical role in recognizing substrates for ubiquitination. In mice, several F‐box proteins, including FBXO36 and FBXO39, are predominantly expressed in testes.

Loss‐of‐Function Variants in CCDC189 Cause Human Oligoasthenoteratozoospermia by Disrupting Sperm Flagellar and Acrosomal Architecture

open access: yesAndrology, EarlyView.
ABSTRACT Background Oligoasthenoteratozoospermia (OAT), characterized by reduced sperm count, impaired motility, and abnormal morphology, is a major cause of male infertility with substantial genetic heterogeneity. However, the underlying genetic etiology remains unresolved in a large proportion of affected individuals.

A Quarter Century of EHD Protein Research: From Endosomal Recycling to Ciliopathies

open access: yesTraffic, Volume 27, Issue 3, September 2026.
Human EHD protein subcellular localization. ABSTRACT Eps15 homology domain‐containing proteins comprise a conserved family of membrane‐remodeling ATPases that regulate endocytic trafficking, membrane fission, receptor recycling, primary ciliogenesis and membrane dynamics across eukaryotes. Since the initial identification of EHD1 and its Caenorhabditis

SPINK2 deficiency causes infertility by inducing sperm defects in heterozygotes and azoospermia in homozygotes

open access: yesEMBO Molecular Medicine, 2017
Azoospermia, characterized by the absence of spermatozoa in the ejaculate, is a common cause of male infertility with a poorly characterized etiology. Exome sequencing analysis of two azoospermic brothers allowed the identification of a homozygous splice

Pig Seminal Plasma Extracellular Vesicles Enhance Motility During Preservation of Epididymal Spermatozoa but Impair Capacitation and IVF Parameters

open access: yesAndrology, Volume 14, Issue 5, Page 1249-1260, July 2026.
ABSTRACT Background Extracellular vesicles (EVs) produced by accessory sex glands play a key role in sperm functionality, influencing motility, viability, acrosome integrity, metabolic activity, and capacitation. Most studies on the effects of EVs on spermatozoa have focused on ejaculated spermatozoa, which have already been exposed to their own native

Chronic Hypoxia Disrupts Spermatogenesis Through ASXL2–EZH2–Mediated Microtubule Destabilization

open access: yesAdvanced Science, Volume 13, Issue 26, 8 May 2026.
This study reveals the mechanism by which chronic hypoxia impairs spermatogenesis via the ASXL2–EZH2 axis, hindering the transition of spermatids from round to elongated forms. Key findings reveal that under hypoxic conditions, downregulated ASXL2 expression reduces EZH2 binding to the CEP162 promoter, leading to decreased H3K27me3 modification and ...

Oxidative Stress‐Related Programmed Cell Death in Male Infertility: Focussing on Ferroptosis

open access: yesJournal of Cellular and Molecular Medicine, Volume 30, Issue 10, May 2026.
ABSTRACT Oxidative stress is a common occurrence in testicular cells of infertile men and is considered a significant cause of male reproductive dysfunction. The increase in reactive oxygen species (ROS) leads to impaired spermatogenesis by activating caspases and generating free radicals from mitochondria, resulting in DNA damage and cell death ...

EIF5A Couples Translational Control With Transcriptional Reprogramming Through Chromocenter Reorganization During Spermiogenesis

open access: yesAdvanced Science, Volume 13, Issue 9, 13 February 2026.
The translation factor Eukaryotic translation initiation factor 5A (eIF5A) is essential for male fertility in mice. It supports the translation of proteins crucial for heterochromatin organization and acrosome formation. eIF5A deficiency disrupts chromocenter integrity, increases chromatin accessibility, and causes transcriptional dysregulation ...
