He maintains that women's bodies produce enough estrogen already. Summary In summary, women already get too much estrogen. They produce estrogen themselves from the follicles on their ovaries and from their fat cells premenopause and perimenopause. After menopause, the woman's fat cells produce estrogen. Women also get estrogen from birth control pills and hormone replacement therapy.
Women get estrogen from chemicals that mimic estrogen know as xenoestrogens .
In summary, taking progesterone will resensitize the estrogen receptors so that your body becomes more sensitive to estrogen supplements or xenoestrogens. Cut out as much xenoestrogen intake as possible. The body's internal production of estrogen is more than sufficient.
