Men’s Sex Hormones

Testosterone (Free)

Testosterone is the primary male sex hormone. It also plays an important role in motivating competitive and sexual behaviors in both men and women, and it increases in response to sexual stimuli and competitive victories. Total T measures total levels of testosterone, whereas free T captures only unbound, biologically active levels of T. Either total T or free T can be measured in serum and plasma, but only free T can be measured in saliva. While testosterone is generally considered immunosuppressive, research finds that it has complex effects on different types of immune function.
