Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — progesterone dominance

Explore how hormones fluctuate through every stage of the menstrual cycle — from menarche to menopause — and discover how estrogen, progesterone, LH, and FSH influence mood, energy, fertility, PMS, migraines, weight changes, and overall women’s health. Learn how menstrual cycle mapping can help identify hormone imbalances and provide deeper insight into symptoms throughout the month.

When sex hormone test results show both oestradiol (E2) and progesterone (Pg) within normal ranges, yet symptoms persist, the Pg/E2 ratio provides a critical additional layer of clinical insight. A low ratio points to oestrogen dominance; a high ratio to progesterone dominance — each requiring a different therapeutic response. This article explains how the ratio is calculated, when it is clinically relevant, and how a real-world case illustrates its practical value.
