As men and women age, processes in the body cause hormones to decrease in amount, resulting in unfavorable health conditions. During menopause in women, the amount of testosterone, estrogen and progesterone women have decreases, raising the possibility of health conditions like heart disease and osteoporosis. Hormone replacement therapy involves taking doses of estrogen and progesterone to prevent or reduce the severity of the aftereffects of menopause.   Men receive hormones in the form of testosterone replacement therapy. As men grow older, the amount of testosterone, a hormone produced in the male genitals lessens, leaving men with a lower sex drive, depression and concentration difficulty. Low testosterone can also negatively plague the body with conditions like decreased muscle mass and fragile bones. Testosterone replacement therapy treats the adverse effects of low testosterone by the administration of testosterone doses, helping to prevent or decrease the severity of the effects.   The Wellness Center offers hormone replacement therapy for men and women in the Dallas, Plano, Frisco, McKinney, Allen and Carrollton areas.
