Amenorrhea in young women who exercise intensely is best explained by an energy shortage prioritizing muscle development and mitochondrial biogenesis over reproduction.

“So this economy of energy between organs is likely what explains if you're a young woman and you exercise a lot, you lose your menes, right? Aminora, then this is not because the the reproductive system is broken or because the ovaries are or are sick or something like that. The best explanation we have is there's a short shortage of energy. Like you're pushing and driving all of your energy budget towards your working muscles towards making more mitochondria in your muscles and there's no more energy to fuel to to to fuel uh reproduction.”
