Testosterone is not only needed in men, but it is also needed in women who are transitioning into menopause. Menopause can cause drop in testosterone level as well as estrogen, and progesterone. When these hormones decline, many women become symptomatic. The three main types of androgens in women are testosterone, androstenedione, and dehydroepiandrosterone (DHEA). Androgens are associated with physical strength and stamina, assertiveness, and engagement and commitment to goals. They are important in maintenance of libido and in maintenance of general overall health. Many women who are lacking testosterone complain of decrease in libido, diminished sexual pleasure, loss of muscle tone, dry hair and skin and lack of energy. Testosterone is also important in protecting against osteoporosis, loss of immune function, obesity, and diabetes. Females experiencing these symptoms can benefit from taking testosterone supplementally.
