Menopause: Body Changes
Although most people know that
Menopause has generated a large population of women who have
excessive rates
of bone fracture and CHD, men also suffer from these conditions.
The male menopause or Andropause is due to hypogonadism-
low testosterone levels. Andropause, the word, appeared in the
literature in 1952 and is defined at the "natural cessation
of the sexual function in older men." Andropause also
refers to sexual regression in men over 40 due to dropping
male hormone levels. Endocrinologically, the difference between
the hypogonadal man and the post-menopausal hypogonadal woman
is not very great. Neither has adequate levels of androgens
or estrogens and they both can be expected to show similar
tendencies; i.e., hypogonadal men also tend to have frequent
MI's and bone fractures from osteoporosis. There is current
evidence of a protective effect of testosterone against both
heart attacks and bone fractures.
The
loss of sexual drive is one of the first changes most people
notice with aging. This decreased libido and failure
to awaken with erections is the foreboding of the impotence
experienced by hypogonadal men. Women too experience a lessening
of their desire but usually this does not occur until their
testosterone levels drop below normal if they have their ovaries
removed. Unfortunately, in men, impotence tends to be accompanied
in most not by frustrated sexual urges or complaints of frustration
but rather by passivity according to Dr. Conrad Swartz. More
than half of the healthy men over age 70 whom he surveyed showed
morning serum testosterone levels at or below 300 ng/dl, the
customary threshold of hypogonadism. At this level men do not
have erections in their sleep or in the early mornings. Passivity
in men soon leads to lack of interest in business, sex, sports
or visual sexual stimulation.
Testosterone is the principal androgen of which 95% is made
by the testes (testicles or sperm producers), 5% in the adrenals
of both sexes and 1% by female ovaries. Testosterone is synthesized
from cholesterol at approximately 6 mg/day, metabolized by
the liver, and excreted in the urine. Testosterone can be bioconverted
into two other steroids at target tissues throughout the body:
This conversion essentially regulates all T activity since
the levels of these steroids can modify the rate of conversion.
Dihydrotestosterone
(DHT) - binds more readily to androgen
receptors than Testosterone. Conversion is noted at prostate,
seminal vesicles (testicles), pubic skin, scrotal skin, axillae
(or armpits), gingival tissues (gums in the mouth). In addition,
to a slight degree in any area of the skin with preferential
absorption on the back, biceps, ribs and thighs in both men
and women.
DHT is 4x more potent than testosterone as an anabolic agent
(increases muscle tissue). This conversion of T to DHT increases
the action of testosterone. Testosterone has both an anabolic
and androgenic (male sex organs) effect.
Estradiol
- a Biestrogen, (there are three estrogens acting on both
females and males {E1, Estrone; E2, estradiol; E3,
Estriol}) 25% are made by the testes, 75% are bioconverted
in liver and the brain from testosterone. This conversion of
T to E2 is the primary cause of male aggression (crankiness),
breast enlargement and loss of sexual drive. Certain hormone
levels will increase this effect and some hormones can decrease
it. (Search words: cancer, estradiol, and regulation).
Low hormone levels of testosterone in men, have negative influences
on both mood and mental abilities, including decline of memory,
and loss of youthful sexual functioning. Studies have shown
that the sexual aging process results in organic impotence,
erectile dysfunction, ejaculatory and urinary problems, decreased
sexual drive or libido and deterioration of the general physique.
Testosterone is the hormone, which regulates the structure
of all body proteins and insures the development and integrity
of the genitals (penis and testicles) in males. The adult testicles
normally produce about 7-10 mg of testosterone daily. A deficiency
causes only modest changes initially such as an increase in
weight (beer belly), progressive aging of the face, muscular
weakening and weakening of bone tissue or osteoporosis.
Lowered testosterone secretion causes low functioning of many
body organs resulting in the eventual failing of memory, sexual
drive and resulting irritability associated with general fatigue
and higher estrogen levels in men. The development of clogged
arteries, varicose veins, hemorrhoids, the increase in abdominal
fat, the atrophy of the skin, high blood pressure and increased
cholesterol are aging associated changes of males that are
reversible with testosterone supplementation. Leydig cell function
is impaired in healthy elderly men as a result of primary testicular
insufficiency. Further studies reveal the presence of an additional
hypothalamic-pituitary disorder of gonadotropin secretion associated
with the aging process. The reason for this pituitary malfunction
is not yet known. # # # # #
