This test checks your level of the hormone Testosterone, the primary sex hormone in males. The high levels of testosterone that men have compared to women are responsible for the development of virtually all the physical differences between the sexes.
In adult males, it controls sex drive, maintains muscle mass and helps make sperm. Understanding your testosterone level may help if you are experiencing low sex drive, infertility, erectile dysfunction and more. Testosterone levels should also be checked regularly by anyone using testosterone supplements.
