I agree with this, but could fertility issues also be playing a part as well? 

I’ve never known so many friends trying and struggling for kids, miscarriage after miscarriage. 

Maybe people just didn’t talk about it a lot before, but over half my friends have PCOS and/or endometriosis. I also know a few whose male partners have low sperm quality. 
When I was younger it seemed like everyone was having kids, now that I’m of age, so many women I know are struggling and can’t. 
I thought I heard that infertility issues are on the rise in the western world?

Definitely. Sperm counts are plummeting around the world and experts aren’t sure why.
