Transdermal estrogen therapy delivered through the skin moderately improved sexual function in early postmenopausal women reported a clinical study published in the JAMA Internal Medicine. The clinical study examined changes in sexual function in 670 post-menopausal women. They were randomized to receive either oral conjugated equine estrogens (o-CEE), transdermal 17β-estradiol (t-E2) or placebo. The study reported that the transdermal treatment was associated with moderate improvement in the overall sexual function score when compared with placebo.
