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 ...

PSMA8‐Containing 20S Proteasome Regulates Spermiogenesis and Male Fertility

Advanced Science, Volume 13, Issue 39, 13 July 2026.
PSMA8 assembles s20S proteasome that degrades specific substrates in elongating spermatids. Degradation of s20S‐substrates activates translation of FXR1‐target mRNAs, which are essential for mitochondrial sheath formation and sperm morphogenesis.

Fosl2 Regulates FSH‐Dependent Follicle Maturation Through Feedback Amplification of FSH/FSHR Signaling

Advanced Science, Volume 13, Issue 37, 3 July 2026.
This study identifies a FOSL2‐driven positive feedback loop that amplifies FSH/FSHR signaling. During FSH‐dependent follicle maturation, FSH induces Fosl2 expression via the cAMP‐PKA‐CREB cascade. FOSL2 in turn binds the promoters of Fshr and estrogen‐biosynthesis genes to enhance their transcription, thereby increasing Fshr mRNA level and amplifying ...

Natural Resistance to Ovarian Hyperstimulation Syndrome in Estrildid Finches Reveals Macrophage GPR183 as a Potential Therapeutic Target

Advanced Science, Volume 13, Issue 42, 28 July 2026.
Ovarian macrophage depletion reverses OHSS resistance in estrildid finches and exacerbates OHSS symptoms in rats. Activating macrophage GPR183 alleviates OHSS by reducing pro‐inflammatory factors, increasing immunomodulatory molecules, remodeling CD44/SDC4‐mediated communication, and restoring immune homeostasis.

Extracellular Vesicles From Human Fallopian Tubes Enhance IVF Embryo Development and Contain Functional Proteins Including YWHAZ

Journal of Extracellular Vesicles, Volume 15, Issue 7, July 2026.
ABSTRACT Extracellular vesicles (EVs) in the mammalian oviduct constitute a key maternal regulatory system that maintains redox balance during early embryogenesis, yet their molecular cargo and functional relevance in human embryos remain poorly defined.

Comparative Effects of Laparotomy and Laparoscopy‐Assisted Embryo Transfer on Oxidative Stress and Thiol–Disulphide Homeostasis in Tuj Ewes

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Laparoscopic embryo transfer in Tuj ewes induces less oxidative stress and better preserves thiol–disulphide homeostasis than laparotomy. These findings indicate that minimally invasive approaches better maintain redox balance and antioxidant defence during embryo transfer procedures.

Spatial Transcriptomic Atlas Reveals That Forkhead Box O3‐Mediated Mitochondrial Dynamics Imbalance Drives Premature Ovarian Insufficiency in Mice

Aging Cell, Volume 25, Issue 7, July 2026.
This study constructed a spatial transcriptomic atlas of POI mouse ovaries and confirmed that decreased FOXO3 phosphorylation triggers mitochondrial dynamic disorder, granulosa cell senescence and ovarian dysfunction. FOXO3‐mitochondrial axis is a shared core mechanism in both drug‐induced POI and physiological ovarian aging, offering promising ...
