Not quite! While trans women obviously don't have menstrual cycles a good chunk of the population suffer from period-like symptoms/PMS just due to similar hormonal fluctuations.

Of course, but treating transgender men like you would a cisgender woman with all the same gendered expectations is both incredibly disrespectful if done on purpose and humiliating for someone who very much does not want to be treated as a woman despite having a period that most likely already makes them very uncomfortable and dysphoric

> only biological women have periods

generally, yes, but there are so many edge cases there with intersex people that it is far easier and more inclusive to just say roughly 50 percent of the human population has periods and avoid having to deal with the million asterisks that come with that statement
