More information


Testosterone and/or GnRH agonists do not provide reliable contraception for people with ovaries 1. They do not prevent pregnancy effectively.


Most contraceptives contain oestrogen which can interfere with testosterone treatment. If you are using testosterone, ask your doctor for a “progesterone-only” contraceptive instead 1.

You can read more about the combined contraceptive pill on the NHS Choices website.

You can find more information specifically for transgender and non-binary people on the FSRH website.
