- Sample required: 1 test tube with 4 mL of saliva
- Lab reporting time: 3 - 4
- business days
Overview
This profile provides a snap shot of male sex hormone levels
from a single saliva collection. Cortisol, DHEA-S, testosterone,
dihydrotestosterone (DHT), androstenedione, progesterone and
estrone are measured. As morning cortisol is an integral component
of this profile, saliva should be collected in the morning
upon awakening. All hormones reported are bioactive free fractions
- those that affect physiology at the cellular level.
Physiology
As men age, they may experience any of the following as a
result of declining levels of testosterone and other androgens
(DHEA, androstenedione): diminished libido; erectile dysfunction;
increased body fat; decreased bone mass, muscle mass and strength;
loss of hair on the head; prostate problems; insomnia, depression,
irritability and loss of zest for life. The Male Hormone Profile
assesses not only the levels of critical androgens; it also
provides a morning cortisol level that in addition to providing
information about nocturnal hypoglycemia and potential infections,
acts to "qualify" the sex hormone levels.
Markers
Cortisol, which is best known for stimulating gluconeogenesis,
is essential for normal glycogenolysis. Cortisol affects the
heart, vasculature, blood pressure, water excretion, and electrolyte
balance. It mobilizes protein stores in all tissues except
the liver; it mobilizes fatty acids from adipose; it is the
precursor of cortisone and acts as an anti-inflammatory; and
it is the primary hormone directing immune function. Cortisol
can stimulate or inhibit gene transcription, promote apoptosis,
and affect bone metabolism and calcium dynamics. It affects
behavior, mood, neural activity, and a variety of central
nervous system biochemical processes. Cortisol affects the
eyes, gastrointestinal tract, reproductive function, and the
production and clearance of other classes of hormones. It
is a major marker of the complex control loops regulating
the sex hormones. The general effect of excess cortisol is
usually stimulatory and catabolic; a deficiency of cortisol
usually results in a slowing of physiology. If morning cortisol
is elevated, it could indicate an infection in the body, nocturnal
hypoglycemia and/or increased risk for a cardiovascular event.
It also means that pregnenolone is being diverted to cortisol
production, perhaps at the expense of producing male hormones.
If morning cortisol is low, it is evidence of chronic stress
and potential depletion of all steroidal hormones, including
male sex hormones.
DHEA is the major precursor of androstenedione, testosterone
and the estrogens (including estrone). It becomes active at
puberty. In this profile, the more stable, sulfated form of
DHEA, DHEA-S is measured, providing a more reliable measure
of DHEA levels than measuring DHEA directly. DHEA is an important
modulator of many physiological processes. It promotes the
growth and repair of protein tissue (especially muscle), and
acts as a counter-regulatory agent to cortisol, negating many
of the harmful effects of continued excess cortisol. When
increased demand for cortisol is prolonged, DHEA levels decline.
DHEA then is no longer able to balance the negative effects
of excess cortisol. Depressed DHEA levels serve as an early
warning of potential adrenal exhaustion. Chronically depressed
DHEA output results in an imbalance in sex hormones.
Testosterone plays many physiological roles in males.
While it is important for primary and secondary male sexual
characteristics, libido and sexual function, muscle and bone
strength and growth of normal body hair, it also has favorable
effects on mood, well being, energy and vitality. Most testosterone
is produced in the testes with some produced in the adrenal
glands. Excessive levels of testosterone have been correlated
with high cholesterol, prostate problems, atherosclerosis
and aggression. Testosterone is the direct precursor of dihydrotestosterone,
an extremely potent androgen.
Dihydrotestosterone (DHT) is made
from testosterone by the enzyme 5-alpha reductase. Along with
testosterone, it is responsible for the formation of primary
sex characteristics of the male during embryonic life and
secondary sex characteristics at puberty. Increased production
of DHT in adult males is thought to cause prostate growth
(hyperplasia) and male pattern baldness. In males, progesterone
acts to limit the conversion of testosterone to DHT. In cases
of benign prostate hyperplasia (BPH), drugs like Propecia
and Proscar are used to inhibit 5-alpha reductase, while not
interfering with the beneficial effects of testosterone.
Androstenedione is a weak androgen
which is a metabolite of DHEA and a direct precursor of testosterone.
Androstenedione can also be converted to estrone by the enzyme
aromatase. In men, excessive androstenedione results in excessive
estrone production. Androstenedione is used by some athletes
in attempts to enhance performance.
Progesterone is largely made from pregnenolone in
the adrenal glands of males. It is calming to the nervous
system and activates the GABA chloride channel to help the
body shut down both physically and mentally for sleep, rest
and recovery. As stated above, it acts to limit the conversion
of testosterone to DHT and is an antagonist to the effects
of estrogens in the bodies of males and females.
Estrone is an estrogen produced
in the fat cells, muscle cells and skin of men and women.
In men, almost all estrone is converted from androstenedione,
which is produced in the testes and adrenal glands. Estrone
is stored in adipose tissue: the more body fat the higher
the level of estrone. This becomes a vicious circle as estrone
promotes the storage of more fat. While a necessary antagonist
to androgens in males, excess estrone can lead to weight gain
and prostate enlargement.
Clinical Use
The Male Hormone Profile is used to assess male sex hormone
levels. If imbalances exist, normalizing adrenal function
using pregnenolone and DHEA and eliminating sources of chronic
stress often brings hormones into balance (refer to BHD #201
Functional Adrenal Stress Profile). If imbalances still exist,
bio-identical testosterone, aromatase inhibitors and bio-identical
progesterone can be used to maintain healthy levels of testosterone
and progesterone, while avoiding the excess levels of DHT
and estrone. As in all cases, a healthy diet, appropriate
exercise and proper sleep provide the cornerstones of health.
Conditions Assessed
This profile assesses male sex hormone imbalance. Symptoms
may include diminished libido; erectile dysfunction; increased
body fat; decreased bone mass, muscle mass and strength; loss
of hair on the head; prostate problems; insomnia, depression,
irritability and loss of zest for life.
Logical Sequence of Testing
The logical sequence of using this test as an initial or as
a follow-up test is determined by a variety of individual
considerations, including the patient's chief complaint, the
array of signs and symptoms, the chronicity of the condition,
the tests previously taken, and the judgment of the practitioner.
