Testosterone is the primary sex hormone in men and plays important roles in women. Low testosterone levels may play a role in erectile dysfunction, decreased sex drive, muscle loss, weak bones, hair loss, fatigue, depression, memory problems, heart disease, and even earlier death.
Optimal testosterone levels may lead to increased muscle mass and strength, higher endurance, enhanced libido, improved mood, lower cholesterol levels, increased bone mineral density, improved cognition and memory, better sleep, and a healthier metabolism.

Free Testosterone is a measure of unbound testosterone that is available to the body’s tissues.
