INTRINSA FOR A WOMANWhat is Intrinsa?
There are about 10 million women who have had their ovaries removed and one in five could suffer from a low sex drive. Removal of ovaries can cause women's testosterone levels to drop by 50 percent. Ovaries are a key producer of testosterone, which helps drive sexual desire. (Men produce testosterone in the testicles.) P&G is seeking approval for Intrinsa for women who have had their ovaries removed. Doctors have been prescribing testosterone products approved for men to women with low sexual desire for years. However, the testosterone women receive is either created in pharmacists' office in forms such as creams or reduced dosages of gels designed for men. Doctors have worried about the consistency of such products. Intrinsa, which P&G licensed from Watson Pharmaceuticals Inc. in 1997, works by releasing over time testosterone through the skin in an amount a women would have produced before menopause. The dose is much lower than the amount prescribed for men.
