i thought that was due to extremely low body fat percentages? it's a common occurrence among gymnasts and i wouldn't be surprised if it affected ballerinas as well.

Heavy lifting too. Lifting is even worse; it floods T levels and cuts mature egg count by up to a quarter. Women have to stop trying to behave like men.

Yeah, women never did heavy lifting leading up to and during pregnancy throughout human history, ever. My fecund farming ancestors never carried goats or wheat bundles across pens or fields, lifted heavy pots to carry water, carried small children in slings on their backs, etc.

Functional strength & endurance (along with bone density) is much different than these "female" bodybuilders

Yes but you're equating women who train with PEDs with women who train natural for fun and/or health. It's the gear that makes her infertile, not lifting.

Heavy lifting, low BF, or manual labor, especially lifting heavy objects at work, decreased mature egg count and antril follicles in eggs in all studies thus far. Women aren’t men. At their fittest they are about as strong as a 14-year-old boy. Cook and clean. Don’t lift.

The only study I find is the test subjects already undergoing IVF? Can you link a study that shows the same result for healthy young women without pre-existing fertility issues?pic.twitter.com/l6XaNP89Nl

That study corroborates what was found in the NTNU health studies of the 80’s (the women had no fertility issues), one of the largest ever conducted, as well as its follow-up in the 90s. You’ll have to dig around to find the exact data. https://www.ntnu.edu/hunt
