The Male Hormonal Health Screen is for all men who want to monitor their hormone levels.
This test assesses hormonal balance in men. This test
includes: Dihydrotestoserone (DHT), Pregnenolone, Estradiol, Sex Hormone
Binding Globulin (Serum), Dehydroepiandroster Sulfate (DHEA),
Testosterone (Free, Direct).
Dihydrotestosterone (DHT) is a biologically active metabolite of the
hormone testosterone, formed primarily in the prostate gland, testes,
hair follicles and adrenal glands. DHT is an androgen or male hormone.
Androgens are part of the biology of gender by stimulating and
controlling the development of masculine characteristics. DHT is three
times more potent than testosterone. DHT is best known for its roles in
causing male pattern hair loss and prostate problems.
Pregnenolone serves as a precursor to other hormones, including
dehydroepiandrosterone (DHEA) and progesterone.The cells of both the
adrenal gland and the central nervous system synthesize pregnenolone
from cholesterol. Human studies show there are much higher
concentrations of pregnenolone in the nervous tissue, than in the
bloodstream. Animal studies indicate the concentration of pregnenolone
in the brain is ten-fold higher than that of other stress-related
hormones (including DHEA).
Estradiol is a sex hormone. It is often called the “female hormone”,
however it also present in men. It represents the major estorogen in
humans. Estradiol has not only a critical impact on reproduction and
sexual function, but also affects other organs including bone structure.
Sex hormone-binding globulin (SHBG) is important in the
bioavailability of sex hormones. Testosterone and Estradiol circulate in
the bloodstream, bound mostly to SHGB. Only a small fraction is
unbound, or “free,” and thus biologically active and able to enter a
cell and activate its receptor. function of these hormones.
Dehydroepiandrosterone (DHEA) is a multi-functional steroid that has
been implicated in a broad range of biological effects in humans and
other mammals. DHEA is produced by adrenal glands, but also synthesized
in the brain. DHEA can be understood as a prohormone for the sex
Testosterone is a steroid hormone from the androgen group.
Testosterone is primarily secreted in the testes of males and the
ovaries of females, although small amounts are also secreted by the
adrenal glands. It is the principal male sex hormone and an anabolic
steroid. In both men and women, testosterone plays a key role in health
and well-being as well as in sexual functioning. Examples include
enhanced libido, increased energy, increased production of red blood
cells and protection against osteoporosis. On average, an adult human
male body produces about forty to sixty times more testosterone than an
adult female body, but females are, from a behavioral perspective
(rather than from an anatomical or biological perspective), more
sensitive to the hormone.
