Reported by Drs. Tyler Lewis and Irwin Goldstein in Journal of Sexual Medicine (Vol. 6, No. 10, 2009) Testosterone gel 1% has been approved for transdermal testosterone application. Preparation names include, Androgel and Testim. Even sharing a wash cloth or hugging can cause transfer. Women have noted growth of hair and lowering of the voice and children have experienced very early onset of pubic hair. Once recognized early-on, fortunately these changes were reversible.
Proper usage should be: allow to dry and cover with clothing and do not share wash cloths unless laundered.
