Men passed the age limit of 45 often acquire a certain set of diseases. More than 50% of the carriers of the Y chromosome (men) of this age group have a weakening male power, in medical language – erectile dysfunction as one of the main symptoms of low testosterone in men over 45. Potency is affected by many different factors – nutrition, stress, irregular sexual life or promiscuity, bad habits, and more. Another disease that often occurs in men in this age category is prostatitis – an inflammation of the prostate. The causes of this disease are in the same area as erectile weakness. In addition to sexual ailments, the men aged 45 face the threatening problems with the cardiovascular system – stroke, heart attack, atherosclerosis, and so on.
In men, low testosterone levels in the body can be supplemented by hormone replacement with testosterone. Testosterone replacement therapy can be prescribed as an intramuscular injection usually given on a biweekly basis; as a patch or gel placed on the skin, or as putty that is applied to the gums of the mouth. Each of the treatments has its risks and benefits. The decision as to which form of testosterone to use depends upon the clinical situation. Discussions between the patient and health care professional often helps decide which medication to use.
In the United States there are currently no preparations that are FDA approved for testosterone replacement for women.
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).
