The article is interesting. In my case, my mother didn't go through menopause early, but I seem on track to do so.
One thing I have always wondered about - in my mother's generation it was very common to have a pelvic ultrasound close to the time of delivery if there was any concern at all as to whether a c-section would be necessary. This was known as pelvimetry x-rays and was common and often done. My mother had one a couple weeks before I was born and the thought was that there was no harm to the fetus from the radiation when they were almost full term.
I can't help but wonder if that did have an impact and if some of us who are now experiencing DOR at a younger age than expected could have been impacted by fairly routine x-rays that were thought at the time to be safe.
