Who Should Not Take Testosterone?
Print PageDo not take testosterone replacement therapy (TRT) if you are a man with any of these pre-existing conditions:
- Known hypersensitivity or allergy to testosterone
- Existing or suspected cancer of the breast or prostate gland
- Severe heart, kidney, or liver disease
- Excessive calcium in the blood (hypercalcemia)
If you are a woman, you cannot take testosterone during pregnancy to avoid giving birth to a son with Klinefelter syndrome or another genetic disorder. The genetic problem already occurred when the cells divided and is irreversible. Do not take testosterone while you are breastfeeding, as it will adversely affect your child through the milk. The benefits do not outweigh the risks.
