Apparently menopause can strike a lot sooner in women who have twins (dizygotic). Guess you lose eggs twice as fast. Very sad if that happens before you have a chance to realize/build a family.
Actually, kinda yes. Men continuously produce sperm but women have a finite supply of eggs. When it runs out, overies stop producing estrogen. Some older women will use HRT to fight some of the effects of menopause, though.
To add to that, although women have millions of eggs to start with, most of these don’t mature and you even lose about a quarter before your first period. The idea is that women with dizygotic twins have increased maturation, causing a higher incidence of releasing two eggs simultaneous and that also leads to faster decreases in eggs. At menopause most women have no eggs left in the ovaries.
Huh. That’s interesting. My personal experience of fertility was that pregnancy happened as fast in my late 30s as it had in my 20s, so I thought they just came out 1 or 2 each month and the rest sort of just stopped developing when you went through menopause (both menarche and menopause were kind of late for me, though). I do use HRT (MHT is what they call it) but certainly not to get fertility oh heck no. It keeps away migraines and helped my thinking as well as bone mass.

How does that work, when we are born with more than a million eggs? It’s not like you run out and that causes menopause.
