In Vitro Sperm–Epididymosomes Interaction Immediately Before Fertilization Changes Sperm Fertility Potential

Andrology, Volume 14, Issue 6, Page 1757-1770, September 2026.
ABSTRACT Background Sperm acquire fertility ability during epididymal maturation mainly in the epididymal caput and corpus, and once matured, are stored in the epididymal cauda. During storage, interactions with cauda epididymosomes (epEVs) may influence sperm fertility potential; however, the role of such interactions on sperm fertility remains ...

Role of the Ca²⁺-ATPase Pump (SERCA) in Capacitation and the Acrosome Reaction of Cryopreserved Bull Spermatozoa

Cells
Cryopreservation of sperm is a resource used for artificial insemination. In the case of bovines, it ensures the reproduction of animals through cells from males with a highlighted genetic background. The fertilisation capacity of sperm cells is achieved

Fish Sperm Subpopulations Detection, Separation, and Application: Current State and Trends

Reviews in Aquaculture, Volume 18, Issue 4, September 2026.
Modern advances in sperm biology highlight the necessity of recognising intra‐ejaculate heterogeneity as a central concept for advancing both the fundamental understanding of fertilisation processes and the development of artificial reproduction techniques in fishes. ABSTRACT Sperm subpopulations represent a fundamental manifestation of intra‐ejaculate

Effects of Caffeic Acid Supplementation on Human Sperm Against In Vitro-Induced Oxidative Stress: Nrf2 Molecular Pathway

Antioxidants
Oxidative stress (OS) is a major cause of defective sperm function. During laboratory handling, gametes are exposed to OS, potentially mitigated by in vitro antioxidant supplementation.

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

Traffic, 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

Targeting and fusion proteins during mammalian spermiogenesis

Biological Research, 2001
Regulated exocytosis is controlled by internal and external signals. The molecular machinery controlling the sorting from the newly synthesized vesicles from the Golgi apparatus to the plasma membrane play a key role in the regulation of both the number ...

Industrial Hydrocarbons Exposure Deteriorates Sperm Integrity and Reproductive Function

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 8, August 2026.
ABSTRACT Occupational exposure to polycyclic aromatic hydrocarbons (PAHs) or metal fumes in the workplace may be detrimental to male fertility. The present study compared sperm concentration, total motility, strict morphology and oxidative stress and SDF levels between 81 men, controls (n = 17) and workers from plastic industry workers (n = 18), steel ...

SIRT Family: Biological Functions and Therapeutic Targets

MedComm, Volume 7, Issue 8, August 2026.
SIRT1–SIRT7 networks from transgenic mice to human‑relevant therapeutic targets. SIRT1–SIRT7 form an isoform‑, organ‑, and disease‑specific regulatory network. Transgenic Sirt1–7 mouse models define central regulatory SIRTs (SIRT1, SIRT3, SIRT6), context‑dependent modifiers (SIRT2, SIRT4, SIRT5, SIRT7), and their key mechanisms and target organs. These
