The aging process is inevitable. However, restoring lost male vitality is within reach. The hormones involved in this restoration can now be collectively measured in one salivary panel using the Regular or Expanded Male Hormone Panels™ (MHP™& eMHP™). The clinical problems that concern men the most can be grouped into three general categories as listed below.

Vigor

Andropause Men of the "boomer" generation not only desire, but actually expect to have a longer life span than previous generations. They also expect to maintain youthful vitality and vigor into their later years. However, due to lifestyle choices and other factors, many men will be disappointed, as their male hormone production slowly declines.
At around puberty, the important male hormone, testosterone reaches adult levels. For a long time it was believed that men maintain adequate levels of testosterone throughout life. Many men in their ?fties or older however, experience a progressive decline in their energy, vitality, sexual performance and mental capacity. This decline has been labeled "Andropause." The causes of andropause are believed to be a reduction in testosterone and other androgens. The testicles show a progressive annual drop of 1-1.5% in testosterone output after age 30. Furthermore, as men age, a 1-2% annual decline in the free-fraction of testosterone and a progressive annual increase of 1-2% in both Luteinizing Hormone (LH) and Follicle Stimulating Hormone (FSH) has been documented. The clinical manifestations of andropause usually lag ten to twenty years behind the onset of hormone decline. Statistically, andropause affects at least 40% of men aged 55 - 65, and up to 80% of those aged 65 years or more.
Knowing the levels of 6-8 hormones measured in the Male Hormone Panels,™ helps you formulate an effective plan to relieve andropausal symptoms.
Regular Male Hormone Panel™ (MHPTM)
Several years ago, Diagnos-Techs, Inc. introduced the ?rst salivary Male Hormone Panel™ (MHP™) which evaluates the androgen pathway by measuring the free fractions of the 6 hormones shown below in boxes.
- Progesterone is a precursor to all androgens and is a physiologic modulator of DHT production.
- DHEA & DHEA-S, the main adrenal androgens are the precursors to both testosterone and estradiol, and the limiting factor in their production especially under stress.
- Androstenedione, another adrenal androgen and precursor to estrone is freely inter-convertible with testosterone.
- Estrone is the major estrogen in men and is the product of peripheral aromatization of androstenedione in fat and muscle tissue.
- and
- Testosterone, the dominant testicular androgen, is the precursor to 5-dihydrotestosterone (DHT). The androgenic effect in various tissues is not exerted by testosterone but by the locally produced DHT.
This panel includes all the 6 tests in the regular MHP,™ plus FSH and LH. Salivary quantitation of FSH and LH is a technological breakthrough that separates Diagnos-Techs from the crowd of copycat laboratories. Testosterone and sperm production in males are the equivalent of estrogen and ovulation in females. The pituitary neurohormones, FSH and LH, stimulate and regulate spermatogenesis and testosterone production respectively.
Early detection of an increase in FSH and LH levels is indicative of a progressive decline in male sexuality and functionality. The clinical utility of the Male Hormone Panels™ is shown below.
Clinical Utility:
- Measuring baseline hormones
- Diagnosing andropause & hypogonadism
- Therapeutic monitoring of HRT
- Balancing of hormones
- Investigating prostate hypertrophy, thinning of hair & hirsutism
- Evaluating low-libido in both sexes
Beneficial Effects
Following the use of MHP™/eMHP,™ treatment plans using hormones to replace and balance endogenous production usually produce several positive effects:
- Increase of fitness and sense of well-being
- Decrease of body fat and increase in lean body mass
- Resolution of hormone dependent libido problems
- Prevention of hair thinning
- Increase in hematocrit and RBC counts
- Mitigation of osteoporosis and stimulation of bone formation
- Decrease in total cholesterol, increase HDL
Common Fallacies:
- DHEA production by the adrenals normally decreases with age.
Reality: DHEA levels in healthy adult males are comparable at any age and only fall as a result of stress-related adrenal exhaustion. - Radioimmunoassay (RIA) is the standard for testosterone testing.
Reality: The testosterone free fraction represents less than 2% of the total hormone. At this low level (Pico-gram) RIA fails to accurately detect testosterone and yields an underestimate of bio-available hormone. This is true for both serum and saliva free fraction testing by RIA. - Testosterone supplementation is detrimental to the liver and lipid profile.
Reality: This only applies to overdosed synthetic testosterone variants that produce supra-physiologic androgenic activity. Monitoring and adjusting natural testosterone intake to maintain physiologic levels, actually improves the lipid pro?le and does not increase LDL, or negatively impact the liver. - Injectable testosterone is best for male hormone replacement therapy.
Reality: Intramuscular testosterone injections abolish the circadian rhythm and result in aggressive behavior. The rapid and uncontrolled hormone absorption causes signi?cant swings in mood and sex drive. Giving more testosterone will not remedy these swings.

Background A 58 yr. old man had been suffering for over 9 months with progressive fatigue and lack of interest in sexual relations. His wife was worried about him missing his weekly golf game. An e-MHP™ saliva panel was done and it revealed:
DHEA, DHT, Progesterone and Estrone were normal Remarks This case study illustrates the subtle and progressive nature of andropause. While the testosterone level was normal, it was maintained at the expense of a higher Pituitary LH stimulation and an increase in demand for adrenal androstenedione. Mild declines in testicular testosterone production prompt the adrenals to produce more androstenedione to compensate for the lagging testicular performance. Treatment Patient was started on a low dose of natural micronized testosterone capsules and was back gol?ng in 3 weeks. Note: Clinics that use DHEA or androstenedione to boost testosterone levels should conduct follow up tests to insure these hormones are not over-spilling into the estrogen pathway. |
