Adverse effects, when testosterone is dosed appropriately, are rare. There is clinical evidence that reports of acne, facial hair and lower voice were associated with higher dosing and are readily reversible with lower doses. Before starting therapy, a cholesterol profile should be obtained since, in rare cases, testosterone has been found to alter the lipid profile. The available safety data indicate that testosterone is contraindicated in postmenopausal women with breast or uterine cancer or who have cardiovascular or liver disease.
The good news is that if you want to maintain an active sex life, there is safe, readily available hormone therapy that can help. If you are using estrogen and therefore have a healthy vagina and progesterone so that you are sleeping better and have more stable moods, and you are still attracted to your partner and want a sexual relationship, a little testosterone might be just the right ticket.
