Research shows its role in the sense of touch, motor function and nervous system maintenance. • Progesterone regulates changes during menses and proves vital for maintaining pregnancy, protecting the uterus lining. Along with preparing the uterus for fertilized egg implantation, progesterone alerts the uterus to shed its lining when pregnancy doesn’t occur. It aids fetal membrane and mammary gland development. Appropriate T3 levels must be established (before statin drugs are considered) to understand the true need for additional therapy. Much of the thyroid hormone secreted by the thyroid gland is in T form. T, a major hormone needed to control basal metabolic rate, increases enzyme secretions and is connected to cell energy production. T is converted to T3, the active hormone. Thyroid hormone supplementation, an inexpensive simple process, restores T3 and T cells to their natural ratio and blood concentrations. Adrenal steroids—essential for life. Adrenal glands release hydrocortisone (cortisol) and other hormones, known as adrenal steroids. These steroids are critical for life and the key to physical and emotional stress response. Unlike other hormones, adrenal steroids generally don’t diminish with age. Both adrenal and gonadal steroids are derived from the basic cholesterol molecule. Through biosynthetic pathways, cholesterol is transformed into different steroid hormone molecules before becoming estrogen, progesterone or testosterone. (The chart on this page shows the progression.) Among its functions, cortisol rouses bodily activities on awakening: It influences protein, carbohydrate and fat metabolism; helps regulate blood pressure; and improves the integrity of blood vessels. Cortisol is also vital for immune function and helping mobilize against inflammation. Plus, it fights bacterial and viral infections. Escalated levels of cortisol can actually suppress immune function. Called the “stress hormone,” cortisol floods your body when emotional upheavals or emergencies arise. Afterward, the brain stops cortisol production to normalize levels. If you’re under chronic pressure and stress, escalated cortisol levels may saturate your body. Over time, these elevated cortisol levels lead to fat accumulation, bloodsugar problems, fatigue, bone loss and immune system impairment. Chronic stress (physical or emotional) can also exhaust the adrenal glands, resulting in subnormal cortisol production—an insidious cycle that can cause premature aging of tissues and total body burnout. Thyroid hormone—your survival depends on it. Thyroid hormone significantly affects metabolic rate and body temperature. As we age, thyroid levels sometimes decrease. Low thyroid levels cause decreased body temperature, lowerthan-normal metabolism, increased cholesterol and increased body fat. Often undetected in traditional medicine, low thyroid levels make it fiendishly difficult to lose weight and can contribute to sluggishness, low energy and depression. Recent studies reveal that most patients with thyroid hormone disorders experience some sexual dysfunctions, which can be reversed by normalizing thyroid hormone levels. Despite the associated changes in sex hormone levels, the high prevalence of ejaculatory disorders and their prompt reversibility suggest a direct involvement of thyroid hormones in the physiology of ejaculation. Since low thyroid isn’t correct, maintaining other activity in the healthy range goes hand in hand with healthy cholesterol.
