Two randomized double-blind, placebo-controlled trials in surgically postmenopausal -- uterus and ovaries removed -- women with hypoactive sexual desire disorder showed a low-dose transdermal testosterone patch treatment resulted in significant improvements in the frequency of satisfying sexual activity and sexual desire, said the study published in the The Journal of Sexual Medicine.

Study leader Dr. Sheryl Kingsberg, of Case Western Reserve University School of Medicine, in Cleveland, conducted the two trials involving 132 participants, who were interviewed after a six-month treatment period.

The findings showed a significant increase in frequency of satisfying sexual activity and sexual desire based on women experiencing the treatment as beneficial.
