Testosterone is a hormone that is produced primarily in the testicles for men and the ovaries and adrenal glands for women. This hormone is essential to the development of male growth and masculine characteristics. For women, testosterone comes in much smaller amounts. Testosterone production increases about 30 times more during adolescence and early adulthood. After early adulthood, it’s natural for levels to drop slightly each year. Your body may see a one percent decline after you’re 30 years old.

The potential for testosterone transfer from healthy males dosed with FORTESTA to healthy females was evaluated in a placebo-controlled, three-way crossover study . The washout period was approximately 29 days. Six males were treated with either FORTESTA (30 mg testosterone) or placebo to one thigh only. At 2 hours after the application of FORTESTA to males, the females rubbed their forearms for 15 minutes on the thigh of the males. Serum concentrations of testosterone were monitored in females for 24 hours after the transfer procedure. When direct skin-to-skin transfer occurred with FORTESTA mean Cavg increased by 134% and mean Cmax increased by 191%, compared to direct skinto- skin transfer with placebo. When transfer occurred with FORTESTA while covering a thigh with boxer shorts, mean Cavg decreased by 3% and mean Cmax increased by 2%, compared to direct skin-toskin transfer with placebo [see DOSAGE AND ADMINISTRATION ].
