Estrogen dominance is widely discussed by many proponents and on many alternative medicine websites, including: Christiane Northrup , former obstetrics and gynaecology physician, believes that estrogen dominance is linked to "allergies, autoimmune disorders, breast cancer, uterine cancer, infertility, ovarian cysts, and increased blood clotting ...
Polyestradiol phosphate (PEP), sold under the brand name Estradurin, is an estrogen medication which is used primarily in the treatment of prostate cancer in men. [1] [9] [2] [10] It is also used in women to treat breast cancer, as a component of hormone therapy to treat low estrogen levels and menopausal symptoms, and as a component of feminizing hormone therapy for transgender women.
Aromatase (EC 1.14.14.14), also called estrogen synthetase or estrogen synthase, is an enzyme responsible for a key step in the biosynthesis of estrogens. It is CYP19A1 , a member of the cytochrome P450 superfamily, which are monooxygenases that catalyze many reactions involved in steroidogenesis .
It is also known as 17β-estradiol (to distinguish it from 17α-estradiol) or as estra-1,3,5(10)-triene-3,17β-diol. It has two hydroxyl groups, one at the C3 position and the other at the 17β position, as well as three double bonds in the A ring. Due to its two hydroxyl groups, estradiol is often abbreviated as E2.
Estrogen dosages for prostate cancer Route/form Estrogen Dosage Oral: Estradiol: 1–2 mg 3x/day Conjugated estrogens: 1.25–2.5 mg 3x/day Ethinylestradiol: 0.15–3 mg/day Ethinylestradiol sulfonate: 1–2 mg 1x/week Diethylstilbestrol: 1–3 mg/day Dienestrol: 5 mg/day Hexestrol: 5 mg/day Fosfestrol: 100–480 mg 1–3x/day Chlorotrianisene ...
The rise in FSH levels recruits five to seven tertiary-stage ovarian follicles (this stage follicle is also known as a Graafian follicle or antral follicle) for entry into the menstrual cycle. These follicles, that have been growing for the better part of a year in a process known as folliculogenesis, compete with each other for dominance. [5]
[103] [28] [104] [105] Estradiol should be avoided when there is undiagnosed abnormal vaginal bleeding, known, suspected or a history of breast cancer, current treatment for metastatic disease, known or suspected estrogen-dependent neoplasia, deep vein thrombosis, pulmonary embolism or history of these conditions, active or recent arterial ...
Early follicles produce more androgens due to 5α-reductase activity, but dominant follicles, with high aromatase levels, shift to an estrogen-rich environment, crucial for their selection. [ 15 ] The LH surge, as previewed earlier, is triggered by rising estradiol levels and occurs about 34-36 hours before ovulation.
