I’ve said this before, but they really need to revise their GCSE biology of the reproductive system.
There are at least six hormones controlling the menstrual cycle, including FSH, LMH, and so on. It’s progesterone that causes the onset of the actual period - a drop in progesterone triggers the onset of the period itself. Period cramps are believed to be caused by the action of prostaglandins in the uterine muscle. Progesterone inhibits prostaglandin production, so when progesterone drops sharply as the period starts, prostaglandin production in the uterine muscle rises as the womb lining starts to shed.
Oestrogen is also at its lowest point in the cycle during that stage - almost nonexistent. It starts to rise again as the period finishes.
So if you’re taking a consistent dose of oestrogen across the month, not only are you not creating a menstrual cycle, but you’re definitely not replicating a period - which is when oestrogen and progesterone are at their lowest points, pretty much absent! The very opposite point to taking oestrogen!
None of these trans people ever seem to notice this. These are well established scientific facts. 😆 Yet all this easily available knowledge doesn’t stop the delusion, or stop daft sites on the internet from claiming that trans women get periods. I even used to get deleted on MN when I pointed this out because it upset the TRAs, despite it being in any human biology textbook (or they could have just popped over to the TTC forum and learned all about charting! 😄)
