Leaving aside the hormones in the environment and thinking about hormones we deliberately injected, I do idly wonder if perimenopause/menopause is, on average, objectively different for women who have had 5-30 years worth of hormonal birth control/taken specific types of synthetic hormones as BC?
My mum went on the (early form of combined?) pill when she got married in ‘68 age 18, I was on depo provera (synthetic progestin) the same age 25 years later.
My maternal gran didn’t have BC or HRT because it just wasn’t a thing when she was in those life stages (she did have a 20+ year co proxamol addiction unquestionably facilitated by her GP tho, so that’s a variable that I wouldn’t want to replicate!)
I’d love to be able to ask them about their experiences but sadly, the nature of middle age/menopause makes comparing notes with grandma unlikely if not impossible (unlike menarche, when mum & gran are often still around).
Probably won’t be any official answers in my lifetime (if the pharmaceutical industry aren’t even motivated to get testosterone licensed for women and into small-dose dispense containers!)
