Amazing. One if the most interesting parts of the article though is that this is such a known phenomenon in practice, not only in theory. Just goes to show what 0.3% works out to when you're on the scale of modern populations.

Personally I also find it admiral how positive people can be in such circumstances. I would be wracked with anxiety in this situation, as the husband at least. But thankfully it seems like our drive to have children overrides many things that would otherwise terrify us.

I always feel weird to think just how common a 0.1% is actually on any slightly bigger population. It is 1 in 1000. Or 100 in 100k and in this case 300... Which isn't actually so many.

And then you start listing up these sort of "rare" conditions and wonder where do we actually end up and how much overlap there is.

Sometimes I feel the opposite. A condition might be described as affecting "only 1% of people" as if to say it's rare and I'm thinking that's so extremely common. I could walk into a highschool and there would be multiple people affected. Or maybe someone in my office has this right now.

Even 1 in 100,000 type conditions mean that multiple people in my city have it nevermind the region.

So do women with two uteruses have two menstrual cycles? Could she be menstruating and not at the same time?

> The fact both ovaries ovulated at the same time, or around the same time, is pretty astounding

Seems to imply that she’s having two menstrual cycles, one for each uterus/ovary.

Aren’t the ovaries usually “in sync”? They take turns ovulating?

>So do women with two uteruses have two menstrual cycles?

No, they don't. Uterus didelphys is caused by two tubes that normally join during fetal developed not joining. There are still only 2 ovaries. Though the bleeding might be irregular due to physical reasons.

Even if ovaries were doubled, there wouldn't be two cycles as hormones are centrally regulated and wouldn't be able to target specific ovaries.

So does that mean that a woman with uterus didelphys is no more likely than any other woman to release two eggs during ovulation?

Yes, exactly.
