For people born with a uterus and ovaries, menopause is a natural and normal process that usually happens between ages 45 and 55. The ovaries stop making estrogen and the making of other reproductive hormones, like progesterone, also slows down. Without these hormones, menstruation stops, as well as the ability to get pregnant.
Menopause can be a welcome relief, as it means no longer worrying about unplanned pregnancy or the need for contraception. This can be sexually liberating! Just remember to continue regular STI screenings every time you have a new partner.
