Natural Estriol Or E3 Is The Safe Estrogen To Take
I believe estriol (E3) is the safest estrogen to take. The reason why is that during pregnancy your body produces large amounts of progesterone and estriol. Women who have many pregnancies and deliver have a smaller chance of breast cancer and endometrial cancer. Therefore, estriol and progesterone are likely to be fairly safe.
Types Of Estrogen
Your body makes three kinds of estrogen. Your body makes estradiol, estriol, and estrone. Your body makes one kind of progesterone. Your body makes natural progesterone. Estradiol is the "strong" estrogen. Estradiol is the estrogen that is responsible for the growth of large breasts, hips and butt. Estradiol helps make a woman feminine. In contrast, estriol and estrone are considered to be "weak" estrogens. All three of these estrogens go into the same estrogen receptor. Estradiol goes into the estrogen receptor and tells the cell to become feminine. Estriol and estrone goes into the same estrogen receptor and does not stimulate it strongly.
Estriol used by Mainstream MDs to Treat Vaginal Atrophy
Estriol cream is used by mainstream MDs to treat vaginal atrophy. Frequently, after menopause, as many as 50% of women begin to have their vagina shrink both lengthwise and in circumfrence. This may make penetration difficult. Also the skin may become thin and subject to bleeding after intercourse. Estriol goes up 100 times during pregnancy. Estriol toughens up the birth canal preparing the birth canal so the baby can pass through. Estriol cream can be used systemically and topically on the vagina to counter vaginal atrophy. I usually recommend 0.5 mg/every other day of micronized estriol cream along with 20-40 mg/day of Natural Progesterone cream 3 weeks out of 4 weeks. The reason why you want to take a week long holiday is that you do not want to becomes less sensitive to Natural Progesteorne and Estriol. Constant use of hormones may result in "down regulation". Your body becomes "used" to the constant hormone stimulation and reduces sensititivity to those hormone. Taking a week "holiday" prevents "down regulation" of your estrogen and progesterone receptors.
