The official journal of @SSRepro. Advancing the science of reproduction through mechanistic, developmental, and translational research across species.

Today is the last day of #SSR2026! Thank you to everyone who stopped by the Biology of Reproduction booth. We loved connecting with the community, sharing our famous sperm & egg floating pens 🧬🥚, and hearing how we can better support reproductive biology research. 📢 SSR members: Publish in Biology of Reproduction with a standard license at no cost as part of your membership benefits. See you next year!

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. academic.oup.com/biolreprod/…
