Why Test Testosterone Levels?
Testosterone is important for maintaining muscle mass and strength, bone mass, fat distribution, sex drive, and sperm production in men.
Low testosterone associations include:
Decreased cognitive function
Lower libido - low sex drive
Increased breast size
Symptoms of low testosterone:
osteoporosis or fracture
lethargy or diminished physical performance are nearly universal, especially in older men.
Testosterone circulates almost entirely bound to transport proteins: Normally less than 1-2% is free. The principal transport protein for testosterone is known as sex hormone binding globulin (SHBG) or testosterone-estradiol binding globulin (TeBG). Testosterone measurements are used to assess erectile dysfunction, infertility, gynecomastia, and osteoporosis and to assess hormone replacement therapy.
