YSM researchers are investigating how #ovarian tissue #cryopreservation - already used to preserve #fertility in advance of #cancer treatment - could delay #menopause in healthy women. Kutluk Oktay, MD, says that could bring additional health benefits. https://t.co/YpOuXxsc0J

We've been interested in this question forever: why are girls born with so many (sometimes more than a million) primordial ovarian follicles? A new paper in press in @BiolReprod with Dr. Sean Lawley (U of Utah) provides some new insights: https://t.co/nLAOL0UmzS

Am convinced the picture in my hotel room is a cross section of an ovary with primordial and Antral follicles. Or maybe I need to visit the opticians… #reprocks 🍳 🥚
