Estrogen dominance – Problems of too much estrogen and its symptoms
Estrogen dominance is a term popularized by Dr. R. Lee – a Harvard trained medical doctor-in the early 90s. From his research, he reached the conclusion that perimenopausal and menopausal symptoms arise as a result of progesterone deficiency. He revolutionized the concept of using estrogen and progesterone for hormone replacement therapy and particularly for treating symptoms associated with menopause.
As you approach menopause, your hormone balance becomes drastically altered. There is low estrogen in the luteal phase (second half of the menstrual cycle) because the quality of the eggs gradually diminishes. You also ovulate less often.
Progesterone is produced by the corpus luteum (what is left after the egg is released from the ovary). In the absence of ovulation,there is no corpus luteum and therefore no progesterone.
