There has definitely been increase in infertility in either women or men or both. This leads to treatments and hopefully pregnancy. Infertility treatments have definitely resulted in more multiples pregnancies and even bigger babies (weights and height). Genetics and changes to lifestyle seem to definitely play a role in infertility and more women are having children later in life causing similar issues.
But aside from what we already know, what I've noticed is the sudden jolt of spontaneous pregnancies, especially multiples. It seems that after all these treatments, hormones and maybe one successful pregnancy due to a shock to the reproductive system. From infertile to fertile. I feel like fertility has weakened over time and we need, interestingly enough, chemicals to correct it; chemicals also being the reason for infertility.
This all just my opinion. The type of stuff you think about at 2 AM but let me know what you think.
