@drmaryclaire: 🧠✨ The Ovary Is Listening — and It Gets Louder With Age We’ve long believed that declining fertility was all about the egg — fewer eggs, older eggs, lower quality. But new research out of UCSF and the Chan Zuckerberg Biohub reveals something far more complex: the ovary is an entire ecosystem, and as we age, its environment — not just its eggs — changes dramatically. Using new 3D imaging, researchers mapped the ovary in unprecedented detail and found something extraordinary: a dense network of sympathetic nerves — the same nerves responsible for the body’s “fight-or-flight” response — winding through ovarian tissue. As the ovary ages, this network becomes even more pronounced. The older the ovary, the more “wired” it becomes. These sympathetic nerves don’t just sit there — they influence when eggs start to mature, when they stop, and how fast the entire system burns out. It means the ovary isn’t just a passive organ quietly releasing eggs. It’s a highly connected, highly reactive part of the body’s nervous system — one that literally feels stress. With age, these nerves grow denser, inflammation increases, and connective tissue stiffens — creating an environment that’s more reactive and less regenerative. The ovary becomes hypersensitive to signals of stress, which may help explain why fertility declines and menopause arrives when it does. As one researcher put it: “Ovarian aging is not just about the egg cells, but about their whole ecosystem.” This new science reframes menopause and fertility not as endpoints, but as part of a larger biological story — one that links ovarian health to overall health and even longevity. 💡 The ovary doesn’t just mark time. It keeps the rhythm of our entire physiology. #WomensHealth #OvarianAging #MenopauseScience #Fertility #ReproductiveHealth \
