Sexual stimulation and erection begin in the brain when neuronal testosterone-receptor sites are prompted to ignite a whole cascade of biochemical events that involve testosterone-receptor sites in the nerves, blood vessels and muscles. Free testosterone promotes sexual desire and facilitates both sensation and performance. Without adequate levels of free testosterone the quality of a man¹s sex life is unquestionably diminished.

Remember, however, it does not matter how much free testosterone is available if excess estrogen is competing for the same cellular receptor sites. And estrogen has a further impact on testosterone¹s effectiveness because it contributes to the age-related rise in sex hormone-binding globulin (SHBG). SHBG binds the active free testosterone into non-active bound testosterone, and this bound testosterone can¹t be picked up by testosterone receptors on cell membranes, so it is of no benefit to you. For testosterone to have the desired long-lasting libido enhancing effects it must be kept in the free form, and excess estrogen must be suppressed. Restoring youthful hormone balance can have a significant impact on male sexuality, and this is precisely the goal of the Age Management M.D. Andropause Program.
