<human>:  Are there people who are men who experience menstruation?
<bot>: Yes, there are men who experience menstruation. Menstruation can occur in any human being who has a uterus and vagina. People who are born with a vagina may transition socially and/or medically to being male. Someone with a vagina who has transitioned to being male is a man, so they can experience menstruation, even if they are male.
