Testosterone has the potential to strengthen her bones. Additionally, she might have been able to prevent the fall if her muscle mass had been better. Estrogen with or without progesterone therapy can further suppress residual testosterone production by the ovary. Taking estrogen partially reduces the pituitary hormone signal to the ovaries and potentially reduces testosterone production. Today we can measure blood levels, so it's easier to monitor the dose.
Excessive testosterone can cause acne, body hair growth and scalp hair loss.
Lower HDL levels increase the risk of heart disease. Although it's true that DHEA levels decline with age, very few well-designed research studies show benefit from replacement. Another New England Journal of Medicine study says DHEA treatment improves sexual function in women who've had their ovaries removed, but not many people are using the supplement for that reason. In addition, many people are taking DHEA in very large quantities. Again, excessive amounts of synthetic androgens drive down HDL cholesterol levels, which is considered a cardiovascular risk.
