Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.Semen, blood serum and morphometric data were collected from Honamli and Hair bucks. Semen samples were evaluated spermatologically and separated for seminal plasma collection, while blood samples obtained on the first and last collection days were processed for serum and stored at –20°C. ABSTRACT Background Breed‐related differences in spermatological

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.This study reported the effect of Mito‐TEMPO on rooster semen quality cryopreserved in Beltsville extender. Semen diluted in extenders containing 10 or 100 µM of Mito‐TEMPO presented higher motility, average path velocity as well as membrane/acrosome integrity, mitochondrial activity, and fertility rate; and lower lipid peroxidation, apoptosis rate ...

Andrology, Volume 14, Issue 6, Page 1579-1589, September 2026.ABSTRACT Background Advanced paternal age is associated with reduced male fertility and testicular dysfunction. Among the molecular regulators involved in aging, SIRT1, a NAD+‐dependent deacetylase, plays a pivotal role in maintaining oxidative balance and cellular homeostasis.

Testis‐Enriched F‐Box Protein FBXO39 Is Important for Spermiogenesis and Male Fertility in Mice
Andrology, Volume 14, Issue 6, Page 1636-1646, September 2026.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.

Improvement of Mouse Spermatozoa Freezing at −80°C With Ascorbic Acid 2‐Glucoside at Thawing Phase
Andrology, Volume 14, Issue 6, Page 1647-1655, September 2026.ABSTRACT Background Sperm cryopreservation is the most common method to maintain a great number of mutant mouse lines. However, the use of liquid nitrogen (LN2) for freezing presents considerable problems in terms of cost, safety, and accessibility. For this reason, the storage of semen samples at ‐80° in ultra‐freezers has been increasingly used in ...

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 ...

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

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 ...
