Why do women need to stay fertile longer? Why not just bring in immigrants from high fertility countries to maintain population stability here? There's literally no non-racist justification for not doing this instead of desperately finding ways for "western" (i.e. white) women to keep having "western" babies, and the increased racial diversity is empirically shown to increase abundance more than literally any other policy or intervention.
I’m T1a1 and even though my mother’s mother died of early onset breast cancer, likely BRCA1/2 related, T1a1 seems to provide some protection against BRCA mediated cancer.
Also IIRC, T1a1 “leaks” heat, so this may be the mechanism it uses.
As you may know in Europe, T1a1 is associated with both Ashkenazi Jews, Scandinavians and Romanians.

OK, terminology question -- what do you call the cycle that cats do have, then? Because they do cyclically go into heat, right?
David Pépin has done some interesting research on AMH (also known as MIS), a hormone that blocks activation of ovarian follicles. https://www.pnas.org/doi/10.1073/pnas.1620729114
I think this has some promise in preventing loss of oocytes over time. (I am a PhD student studying ovarian biology, oogenesis, and stem cells.)
You are also correct in thinking that the MSC exosome paper is bullshit.

Have you looked at mtDNA in this regard?
