Testosterone is important for maintaining muscle mass and strength, bone mass, fat distribution, sex drive, and sperm production in men.
Low testosterone associations include:
Low energy
Reduced strength
Decreased cognitive function
Lower libido - low sex drive
Increased breast size
Depressed mood.
Symptoms of low testosterone:
(low libido
erectile dysfunction
osteoporosis or fracture
sleep disturbance
depressed mood
lethargy or diminished physical performance are nearly universal, especially in older men.
Clinical Significance
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.
ESTRADIOL
Elevated estradiol levels in males may be due to increased aromatization of androgens, resulting in gynecomastia, (man boobs). There is a reason and it's not just exercise. If this concerns you have this test and see if you are in balance.
