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

Pregnancy Outcomes Following Artificial Insemination and Embryo Transfer in Dairy Cows—Expectations vs. Reality

Reproduction in Domestic Animals, Volume 61, Issue S2, September 2026.
ABSTRACT Bovine embryo transfer (ET) has been a consistently growing market worldwide with in vitro produced (IVP) embryos now far outnumbering those produced by traditional superovulation. Because transfer of a viable blastocyst‐stage embryo to the uterus bypasses many of the potential biological causes of early pregnancy failure associated with ...

Women in space: A review of known physiological adaptations and health perspectives

Experimental Physiology, Volume 111, Issue 9, Page 3944-3967, 1 September 2026.
Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.

Audience effects in the Atlantic molly (Poecilia mexicana)-prudent male mate choice in response to perceived sperm competition risk? [PDF]

, 2009
Background Multidirectional interactions in social (or communication) networks can have a profound effect on mate choice behavior. For example, Poecilia mexicana males show weaker expression of mating preferences when being observed by an audience male ...

The RNA‐Binding Protein PARN Remodeled 3′ UTR Structure Defines Poly(A)‐Loading Sites to Mediate Immunoglobulin Homeostasis

Advanced Science, Volume 13, Issue 43, 3 August 2026.
ABSTRACT Class Switch Recombination (CSR) is essential for generating high‐affinity antibody isotypes from IgM during adaptive humoral responses. Despite well‐established roles for various transcription factors, whether CSR is subject to dedicated post‐transcriptional control represents a significant gap in knowledge.

Follicle Size Regulates Cytoplasmic Maturation, Lipid Content, and Embryo Cryosurvival in Bovine Oocytes Matured In‐Vitro

Molecular Reproduction and Development, Volume 93, Issue 8, August 2026.
Follicle size modulates bovine oocyte cytoplasmic maturation during IVM. Oocytes from larger follicles exhibit reduced lipid accumulation, fewer transzonal projections, distinct cumulus cell metabolic signaling, and greater embryo cryosurvival, indicating improved cytoplasmic maturation and lipid regulation despite similar developmental rates ...

Sexual selection in a transparent worm : insights from fluorescent sperm [PDF]

, 2015
Sexual selection is a potent source of selection underlying the evolution of sexual dimorphism, reproductive strategies and mating systems. Although sexual selection was initially thought to occur exclusively at the pre-copulatory stage (e.g., contests ...

Factors associated with the reproductive performance of ewes inseminated laparoscopically in England and Wales: A longitudinal study

Veterinary Record, Volume 199, Issue 1, Page e21-e29, 4/11 July 2026.
Abstract Background Laparoscopic intrauterine artificial insemination (Lap‐AI) is used in sheep genetic improvement programmes. However, the lambing rate (LR) (i.e., the proportion of inseminated ewes that lamb) following Lap‐AI is variable. Previously, one small UK study investigated factors associated with LR, but it did not adjust for dependencies ...
