Can I get pregnant?

If you have a uterus and ovaries and ever have sex with some one who has sperm, you can get pregnant. This is true even if you are taking testosterone and don’t get periods.

What kind of birth control can I use if I take testosterone?

We don’t recommend contraceptive methods with estrogen. The best birth control methods are IUDs. Copper IUDs have no hormones and many trans men like these, but they can cause uterine cramps and bleeding. Hormonal IUDs have only a small amount of progesterone and this does not interfere with testosterone and rarely causes other hormonal side effects (like mood changes weight gain). One of the benefits is that most people lose their periods completely (even if not on testosterone).

Other contraceptives that work well and don’t interfere with testosterone are the injections every three months (DepoProvera), implants (Nexplanon, not available in Canada until next year) and progesterone pills (Micronor). These usually take periods away, but contain more progesterone than the hormonal IUDs and therefore have more side effects.

And, of course, there are condoms that protect against sexually transmitted infections as well as pregnancy. Pulling out (not ejaculating inside) reduces risk of pregnancy but is not enough.
