I've read that Testim gel should not be applied to the scrotum. Why? What harm, if any, could be done if Testim were to be applied to the scrotum? Since the skin of the scrotum is 40 times more permeable than that of the shoulders and upper arms, does it stand to reason that if Testim were applied to the scrotum that there would be substantially more absorption and bioavailability of testosterone than if otherwise applied to the shoulders and upper arms? If one can tolerate the mild pain of Testim, an alcohol-based gel, applied to the scrotum, is it othewise okay to apply some or all of the gel to the scrotum? Please advise. Thanks.
