A systematic study at Monash University in Australia has found that the addition of testosterone to hormone therapy in women after menopause enhances their sexual function.
They also found that it may also reduce levels of HDL cholesterol. Although Testosterone, a sex hormone produced by the endocrine system, is thought of as a male hormone, women secrete small amounts of it as well. Testosterone has previously been shown to improve sexual function, bone mineral density, muscle mass, increased lean body mass, mood, energy and psychological well being.
However, there may be side effects in further studies of Testosterone use, it is possible that long-term side effects that have not been observed with six months use could occur. These might include voice changes, increased body and facial hair, acne. These have not been reported with short-term use.
