Men can get pregnant if they were assigned female at birth and still have a uterus and ovaries. This includes some transgender men. Cisgender men who do not have these reproductive organs cannot carry a pregnancy.
Testosterone may stop menstrual periods and reduce ovulation, but it is not a reliable form of birth control. Pregnancy can still happen, even when periods have stopped. Some transgender men are also able to conceive after stopping testosterone, although the time it takes for ovulation to return can vary.
Anyone planning a pregnancy should speak with a doctor before trying to conceive. Testosterone should be stopped before pregnancy and should not be used during pregnancy because it may affect fetal development. Pregnancy care is generally similar to other pregnancies, but respectful, gender-inclusive support is especially important.
A gynecologist, obstetrician, or fertility specialist can provide guidance about contraception, fertility, pregnancy planning, and prenatal care. Hormone treatment should never be started, stopped, or adjusted without medical supervision.
