At age 35? I know you were just throwing a number out, but at age 35, about 10% of women are completely infertile, and the odds of successfully conceiving are significantly decreased, meaning that even in that 90% who are fertile, they may not be able to get pregnant quickly enough to take advantage of their fertility before becoming infertile, even if they're ready to go and start reproducing right on their 35th birthday. And, on top of THAT, the rate of birth defects and chromosomal abnormalities dramatically increases after 35 (with another inflection point after roughly 40).
So, yes, while it would significantly decrease the population, you'd be dramatically increasing the number of people, mostly women, who simply aren't able to have children at all.

- erroneousfunk 10y agoThere are tons of studies and data that can be found in many places (obviously, it's a fairly common topic of research) but here's Wikipedia: https://en.wikipedia.org/wiki/Age_and_female_fertility https://en.wikipedia.org/wiki/Age_and_female_fertility They also have a table there, outlining the theoretical "percent of women who will fail to have a live birth" if they start trying to conceive at a certain age. Not the same thing as infertility -- they may be fertile, just unlucky up until the point that they're actually infertile. The numbers are a little all over the place, but for 35 year old women, it's somewhere between 13 and 22%
