I'll answer the last question first.
I'm sorry, my French isn't very good.
The $1 trillion worldwide that we could save if we achieved more knowledge in women's health research is from the World Economic Forum's report that was just released a month ago or so.
One of the major federal funding agencies is the Canadian Institutes for Health Research. They have something like 58 committees. They'll be on neuroscience, and biological and clinical aspects of aging. None of them is for women's health in particular. There is one on maternal and child health. I've tried to get funding through them. I can't get funding through them, because it's mostly on the child, as you might imagine.
There's another one called gender, sex and health, GSH. That's where I tend to get my funding. If you look on Twitter/X you'll see my pinned rant. I was really angry, because in that committee I put in a grant five times on looking at how pregnancy affects the aging brain, and they kept asking me to add males. Males don't get pregnant. I couldn't do the work that they wanted me to do. Also, there is a lack of research and publications in this area. There is this mistaken belief that girls, females and women are harder to study, because they're more hormonal. We have these menstrual-cycle phases, so we're more difficult to handle or interpret. However, just for a little bit of levity, human males have a 50% decline of testosterone that occurs daily. I have one little thing that I say: Given the monthly fluctuation in females and a daily fluctuation in males, who's more hormonal now?
There have been many studies done to show that there's no difference in variability within each sex. I can't tell you. I wish I knew the answer.
