About the Test
Testosterone is often referred to as “the male sex hormone”, but it is also produced in (and important for) females. In males, testosterone helps regulate sex drive and erectile function, muscle mass and strength, body fat distribution, bone density, and sperm production. In females, the role of testosterone is only partially understood, but it helps produce estrogen and may help regulate how eggs develop in the ovaries. Abnormal testosterone levels in both males and females may result in changes to your overall health and physical appearance.
Testosterone testing may provide insights to men experiencing symptoms of hypogonadism (ie, low testosterone) - which are associated with aging and medical conditions like diabetes, high blood pressure, and obesity. Testing may provide insights to women experiencing symptoms of hyperandrogenism (ie, high androgen levels, like testosterone) – which are associated with medical conditions like polycystic ovary syndrome (PCOS).
With Quest, you can buy a testosterone test online and get testing at a nearby location – no doctor’s visit required.
