Can sperm metabolism predict fertility?

New research suggests yes. By analyzing how sperm use energy, scientists identified key markers linked to fertility—potentially improving how we evaluate reproductive success.

How do you study the uterus without studying the whole animal?
Researchers created lab-grown "mini tissues" from horse uterine cells that mimic real structures + real cycle changes.
A promising tool for advancing fertility and reproductive research.

Creating genetically modified mice just got more precise.
Researchers used a tool from the little brown bat (Myotis lucifugus) to efficiently produce mice with a single copy of a gene—improving accuracy for research models.
A small tweak with big impact for science.

What helps an embryo develop in its earliest stages?

New research in sheep shows a protein (TGF-β3) supports embryo growth by helping cells manage fats—key for forming the placenta later on.

A small detail with big implications for fertility + pregnancy research.

Latest #EditorsChoice! New research shows germline stem cells can restore fertility in mice without removing existing testis tissue first. Success depends on recipient age — younger testes allow better colonization and offspring production. https://t.co/11eWmTF8L7

Editor’s Choice in Biology of Reproduction:
A new study shows that IPO5 is essential for early embryonic development and required for male—but not female—germline development, as demonstrated through multiple knockout mouse models.
