Testosterone is a steroid hormone produced in the adrenal glands of both sexes and in the testes of males and the ovaries of females. Testosterone is largely responsible for the formation and maintenance of male sex characteristics, including both the larger bone and muscle development seen in males. The testosterone levels in humans are regulated by hormones released from the brain; in males the hypothalamus and pituitary glands in the brain increase testosterone during puberty and male characteristics develop (for example, penile enlargement, facial hair, interest in sex).
Menopause should not be considered a disease but an accepted transition in women from fertility to cessation of menstruation. Many women find menopause to be a positive experience since they no longer have to worry about pregnancy and can enjoy luxurious sex in the morning without interruption from children or carpools. Weight gain is common but is not a part of the menopause. As Dr. Patricia Allen, author of Staying Married… and Loving It, stated on a recent TV interview Embracing Menopause , “Hormones do not make you fat, it is what you eat that makes you fat”. This is true but difficult for many people to accept. However, many postmenopausal women complain of a decreased desire to exercise, which could contribute to weight gain after menopause.
