Hormones work through precise feedback loops between the brain, ovaries or testes, adrenal glands, and thyroid. When production drops or conversion pathways are disrupted, even modest shifts of 10-20 percent in circulating hormone levels can produce meaningful symptoms. The Menopause Society recognizes these transitions as significant, treatable health events rather than simple aging.
For women, estrogen and progesterone levels naturally decline beginning in the mid-30s, accelerating during perimenopause and menopause. For men, testosterone typically decreases by roughly 1 percent per year after age 30. These cascading changes affect downstream systems including metabolism, sleep architecture, cognition, and cardiovascular health.
Chronic stress compounds these shifts by elevating cortisol, which suppresses sex hormone production and thyroid conversion. Evaluating these patterns often begins with comprehensive Hormone Replacement Therapy (BHRT) consultation and targeted lab testing.
