> Many women do not know this. It's not common knowledge. I'd wager most men also do not.

I'm sorry but what kind of bubble of misinformation do you live in FFS?

Women are aware of what a period is and the connection to eggs when they start, they are aware of what menopause is, they are aware that eggs become less fertile with age.

This is common knowledge across the major Commonwealth countries (UK, Canada, Australia).

I'm not sure what your authority is to speak so authoritively and yet incorrectly for women at large particularly as it appears you had an actual university education in Canada but, seriously, check your circle .. and if if it's reinforcing your notions then consider having a wider and better informed circle and look to why it lives in a bubble.
