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?

Yep, I’ve seen this as well. It seems like if you took 10 women (maybe men) the majority of them have reproductive health issues. Perhaps these have been here all along (and very so could be because you have to fight tooth and nail for any doctor to actually help your reproductive health rather than just put a bandaid on it). But there have been studies over the recent decade/years that show how the populace’s hormones and endocrine system overall have been affected by a number of different outside factors. Food, chemical cleaners, face/skin care, makeup, as well as birth control second order effect of being entered into the sewage/water system from the excrement/urine of those who use it or any other hormonal medication.
