More than 85 percent of the women who said the patches helped said they were "probably or definitely" interested in continuing to use them, while over 90 percent of those who said the patches didn't help said they were "probably or definitely" not going to keep using them.
It's not clear why some women benefit from the patches and others don't, Kingsberg said; perhaps their sexual problems aren't related to drive, or don't respond biologically to the hormone. But the findings show, she added, that a woman will know within three months whether or not the product works for her.
The FDA has not approved any type of testosterone therapy for females, she added, but it's estimated that as many as one in five U.S. testosterone prescriptions are written "off-label" for women.
