Hormone Replacement: The Final Answer To Aging

Your endocrine system is a complex network comprised of integrated hormone-producing glands and organs. Its function, like that of the nervous system, is communication; the endocrine system produces and releases different types of hormones to maintain and control a number of important functions throughout the body, including growth and development, metabolism, and tissue function. A hormone imbalance (either too much or too little hormone volume) can have a drastic effect on body function.

The complementary function of the two systems provides for full coordination of body responses of goats. The ultimate purpose of hormones is to provide a means of adaptation between the body and its external or internal environment. Hormones may be classified into two categories by their chemical composition. Steriod hormones are secreted by the adrenal cortex and the gonads. Protein or protein-like hormones are secreted from the pituitary gland, thyroid, pancreas and adrenal medulla.

Hormones regulate bodily reactions through their effects on target organs, but they merely modify the rate at which target organs perform functions. They do not cause a reaction or event to occur per se that could not otherwise occur. Hormones also function at extremely small levels in the body, with the rate of secretion varying according to the level of stimulation. The pituitary and the hypothalamus work together as a functional unit to coordinate the endocrine and nervous systems in their actions, with the hypothalamus being the ”center” of the autonomic nervous system and master of the pituitary.

Hormone replacement – simply replenishing the hormones we lose with age – has intrigued scientists for centuries. One of the first investigators was a French doctor, Charles Edouard Brown-Squard, who wrote an article for the July 1889 issue of The Lancet entitled “The Effects Produced on Man by Subcutaneous Injections of a Liquid Obtained from the Testicles of Animals.” His thesis held that since young men were virile and older men less so, the only natural solution was to inject older specimens with semen.

Hormone replacement may also be effective at reversing the effects of aging on muscle or promoting reverse cholesterol transport (RCT) via the induction of cholesterol ABC transporters. Hormone therapy programs aren’t only for women. Men experience a more gradual loss of hormones, mainly testosterone. Testosterone therapy may stimulate growth of the prostate. If early prostate cancer is present, testosterone may stimulate the cancer’s growth. Therefore, men who have prostate cancer should not take hormone replacement. It is important for all men considering testosterone replacement therapy to undergo prostate screening before starting this therapy.

In general, hormone replacement is safe. It is associated with some side effects, including acne or oily skin, mild fluid retention, stimulation of prostate tissues, breast enlargement and decreased testicular size. Moreover PMS type symptoms can occur with hormone replacement when the progestogen is taken cyclically (sequential therapy). These symptoms can often be helped by changing the preparation to one using a different type or route of progestogen. Weight gain is often greatly feared but in fact weight gain around the time of the menopause is very common and hormone replacement does not generally cause significant further weight gain.
