Contrary to popular belief and cheesy internet ads, it isn’t testosterone that plays a central role in a man’s sexual libido and ability to get an erection, it’s dopamine. Testosterone plays more of a supportive role in our sex drive by stimulating the brain to produce more dopamine. So while low T can result in low libido, it’s because there isn’t enough T to stimulate sufficient dopamine for a healthy sex drive. It is therefore possible for a man to have high total and free testosterone levels, but low dopamine (or blunted dopamine sensitivity – more on that later), and thus a low or absent sex drive. Testosterone’s dopamine-stimulating abilities also explain why testosterone replacement therapy companies advertise that increasing your T can give you more energy and drive to do other stuff in life. It’s not the T itself, but rather the dopamine that T triggers in the brain that gives you that boost. The more you know.
