Testicular toll with viral intrusion: Molecular insights into the impact of chronic HIV infection on male fertility

Clinical and Translational Medicine, Volume 16, Issue 9, September 2026.
The molecular mechanisms contributing to impaired fertility in HIV+ males remain poorly defined. Using a human immunodeficiency virus (HIV) transgenic (Tg) rat model, we demonstrate key structural and functional sperm regulators including cation channel of sperm (CatSper)1–4 channels and mitochondrial biogenesis genes were markedly downregulated ...

Reproduction on the Rocks: Life History of a Freshwater Macrobioeroding Bivalve

Ecology and Evolution, Volume 16, Issue 9, September 2026.
ABSTRACT Macrobioerosion, the excavation and removal of consolidated mineral substrates by macrofauna, is well established in marine systems, where macrobioeroders drive carbonate cycling, sediment production and habitat formation. In freshwater ecosystems, however, it has been documented in only a small number of invertebrate taxa and remains a poorly

Epigallocatechin Gallate From Tea Delays Oocyte Aging After Ovulation in Mice

Food Science &Nutrition, Volume 14, Issue 9, September 2026.
In this study, we find that EGCG delays post‐ovulatory oocyte aging and improves the quality of aged oocytes. EGCG may reduce ROS levels in aged oocytes by the NRF2‐KEAP1 pathway. The embryo developmental potential of aged oocytes is also increased by EGCG. ABSTRACT In clinic, once the ovulated oocytes cannot be fertilized timely, they begin to undergo

The Therapeutic Effects of Crocus sativus L. and Its Constituents on the Improving Treatment of Azoospermia: A Narrative Review

Health Science Reports, Volume 9, Issue 9, September 2026.
ABSTRACT Background and Aims Azoospermia, defined as the complete absence of sperm in the ejaculate, is a major cause of male infertility and is classified into obstructive and non‐obstructive forms. While obstructive azoospermia is primarily mechanical in origin, non‐obstructive azoospermia (NOA) is characterized by impaired spermatogenesis and is ...

Paternal Exposure to the Neonicotinoid Pesticide Clothianidin Alters Sperm MicroRNA Profiles in Mice and Intergenerationally Reduces Locomotor Activity in Male Offspring

Journal of Applied Toxicology, Volume 46, Issue 9, Page 3164-3176, September 2026.
ABSTRACT Accumulating evidence suggests that paternal environmental factors have epigenetic effects on sperm and influence offspring. Neonicotinoid pesticides (NNs), which are widely used around the world, are known to affect offspring phenotypes through maternal exposure in mice, but the effect of the paternal exposure remains unknown.
