Young women with low libido had good sex more often after using a testosterone spray, Australian researchers said on Thursday.The spray, designed by Australian group Acrux Ltd. and being developed by U.S.-based Vivus Inc., has previously worked on women who have passed menopause, who typically have low testosterone.However, investigators said the company may be able to win approval for its product more easily by targeting young women, where the spray would take testosterone back to normal levels.
