> For instance, testosterone therapy often carries risks. Supplementing the hormone signals the body to shut down production of its own supply, which can shrink the testicles and suppress sperm. Some researchers have even studied testosterone for its contraceptive effects.

> Moreover, because testosterone revs up oil glands and hair follicles – and partly converts them to estrogen – it can also bring about acne, balding and even some breast tissue growth.
