Now available! Results from our interdisciplinary collaboration suggest that the timing of onset of the menopausal transition and menopause are determined by the pattern of loss of primordial ovarian follicles. science.org/doi/10.1126/scia…

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. brnw.ch/21wGf4q

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: academic.oup.com/biolreprod/…
An(other) interesting example of a biological process taking advantage of random walks: arstechnica.com/science/2023…

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 🍳 🥚
Here's a new article on the accelerated ovarian aging seen in a mouse model of Classic Galactosemia. Congratulations to Dr. Hagen-Lillevik and thanks Dr. Kent Lai for such fun and productive ongoing collaboration!
