Transdermal testosterone treatment in women with impaired sexual function after oophorectomy.
BACKGROUND The ovaries provide approximately half the circulating testosterone in premenopausal women . After bilateral oophorectomy , many women report impaired sexual functioning despite estrogen replacement . We evaluated the effects of transdermal testosterone in women who had impaired sexual function after surgically induced menopause . METHODS Seventy-five women , 31 to 56 years old , who had undergone oophorectomy and hysterectomy received conjugated equine estrogens ( at least 0.625 mg per day orally ) and , in r and om order , placebo , 150 microg of testosterone , and 300 microg of testosterone per day transdermally for 12 weeks each . Outcome measures included scores on the Brief Index of Sexual Functioning for Women , the Psychological General Well-Being Index , and a sexual-function diary completed over the telephone . RESULTS The mean ( + /-SD ) serum free testosterone concentration increased from 1.2+/-0.8 pg per milliliter ( 4.2+/-2.8 pmol per liter ) during placebo treatment to 3.9+/-2.4 pg per milliliter ( 13.5+/-8.3 pmol per liter ) and 5.9+/-4.8 pg per milliliter ( 20.5+/-16.6 pmol per liter ) during treatment with 150 and 300 microg of testosterone per day , respectively ( normal range , 1.3 to 6.8 pg per milliliter [ 4.5 to 23.6 pmol per liter ] ) . Despite an appreciable placebo response , the higher testosterone dose result ed in further increases in scores for frequency of sexual activity and pleasure-orgasm in the Brief index of Sexual Functioning for Women ( P=0.03 for both comparisons with placebo ) . At the higher dose the percentages of women who had sexual fantasies , masturbated , or engaged in sexual intercourse at least once a week increased two to three times from base line . The positive-well-being , depressed-mood , and composite scores of the Psychological General Well-Being Index also improved at the higher dose ( P=0.04 , P=0.03 , and P=0.04 , respectively , for the comparison with placebo ) , but the scores on the telephone-based diary did not increase significantly . CONCLUSIONS In women who have undergone oophorectomy and hysterectomy , transdermal testosterone improves sexual function and psychological well-being
