Testosterone patches are effective at treating low libido in post-menopausal women. Low libido may also occur as a symptom or outcome of hormonal contraceptive use. Women may also use testosterone therapies to treat or prevent loss of bone density, muscle mass and to treat certain kinds of depression and low energy state. Women on testosterone therapies may experience an increase in weight without an increase in body fat due to changes in bone and muscle density. Most undesired effects of testosterone therapy in women may be controlled by hair-reduction strategies, acne prevention, etc. There is a theoretical risk that testosterone therapy may increase the risk of breast or gynaecological cancers, and further research is needed to define any such risks more clearly.
According to The Mayo Clinic , male hypogonadism can begin during fetal development, before puberty, or even during adulthood. In the case of adult hypogonadism, the condition can cause erectile dysfunction, infertility, decrease in beard and body hair growth, decrease in muscle mass, development of breast tissue, and loss of bone mass. The condition can also cause mental and emotional changes similar to those women may experience during menopause. These may include fatigue, decreased sex drive, difficulty concentrating, and hot flashes, The Mayo Clinic reported.
