Estriol - Wikipedia, the free encyclopedia Estriol (also oestriol) is one of the three main estrogens produced by the human body. Levels of estriol in non-pregnant women do not change much after menopause, and levels are not significantly different from levels in men. DHEA is produced by the adrenal cortex of the fetus, this is converted to estriol by the placenta. en.wikipedia.org /wiki/Estriol   (143 words)

Estriol Estriol containing cream is suitable for the treatment of chronic vaginitis and cystitis developed on the base of climacteric epithelium atrophy of urogenital system. The agents hyaluronidase, estriol, and base cream (as a control) were applied topically to separate animal groups for 5 weeks, and their effects were studied on tissue expansion. Estriol was administered for a six-month period as estrogen replacement therapy to 52 symptomatic postmenopausal women. www.salivatest.com /store/bhrt_estriol.html   (4552 words)

College Pharmacy - Estriol (E3) Estriol is the estrogen that is made in large quantities during pregnancy and has potential protective properties against the production of cancerous cells. Estriol's anti-cancer effect is probably related to its anti-estrone properties it blocks the stimulatory effect of estrone by occupying the estrogen receptor sites on the breast cells. Estriol is the estrogen that may be most beneficial to the vagina, cervix and vulva. www.collegepharmacy.com /specializations/estriol.asp   (283 words)

Estriol May Ease Relapsing-Remitting MS in Women Administration of oral estriol, the predominant estrogen of pregnancy, to nonpregnant women with relapsing-remitting multiple sclerosis increased protective immune responses and decreased the number and volume of gadolinium-enhancing lesions on monthly cerebral magnetic resonance imagings (MRIs), a phase I study has shown. Estriol, produced by the fetal placental unit, is not detectable at appreciable amounts until pregnancy, when it progressively increases. Previous studies have found that estriol administered to mice with experimental autoimmune encephalomyelitis resulted in amelioration of multiple sclerosis, with a favorable shift in immune response similar to that seen during pregnancy. www.neurologyreviews.com /nov02/nr_nov02_estriol.html   (914 words)

Women: Estriol, the Forgotten Estrogen?, by JALVIN H. FOLLINGSTAD, MD Estriol, E3, although a small amount may be secreted by the ovary, is a converted estrogen. The preliminary investigation was initiated as a trial of the safety and estrogenicity of the hormone in postmenopausal women with breast cancer and not primarily to test its activity as an alternative therapeutic estrogen for breast cancer. Estriol, though readily available in Europe, is not available in the United States except for research projects and then with restrictions. www.selfgrowth.com /articles/lee19.html   (1449 words)

Estriol Estriol is one of the three major naturally occurring estrogens, the others being estradiol and estrone. Estriol is produced almost exclusively during pregnancy and is the major estrogen produced in the normal human fetus. Estriol has been suggested to be less carcinogenic than estradiol and estrone in animal studies. www.aeron.com /estriol.htm   (256 words)

Estriol   (Site not responding. Last check: 2007-10-20) Due to conflicting reports on the effect of estriol on the endometrium, it is probably wise to prescribe a natural progesterone in conjunction with the estriol for a period of at least 10-14 days per month in order to shed any uterine tissue which may have built up as a result of the estriol administration. While estriol appears to be safer than estrone and estradiol and, in some situations, provides some protection against carcinogenesis, it appears its use in breast cancer patients with active disease or with patients at high risk for breast cancer should be approached with caution. Estriol is a weak estrogen which is capable of exerting either antagonistic or agonistic effects depending on dosage size and schedule, and whether it is given alone or in conjunction with a stronger estrogen such as estradiol. www.thorne.com /altmedrev/fulltext/estriol3-2.html   (5358 words)

[No title] In a small-scale, early-phase trial of the hormone estriol, a form of estrogen, women with relapsing-remitting MS showed decreases in MRI-detected brain lesion activity and immune responses during treatment, suggesting that additional study of estriol is called for to determine longer-term efficacy and safety. Because the hormone estriol is elevated during later stages of pregnancy, and mice given pregnancy levels of estriol were shown to have fewer symptoms of an MS-like disease, the hormone was considered as a candidate for testing against MS. Because the hormone estriol (a form of estrogen) is elevated during later stages of pregnancy, and mice given pregnancy levels of estriol were shown to have fewer symptoms of EAE, the hormone was considered as a candidate for testing against MS. www.mult-sclerosis.org /news/Oct2002/NMSSOnEstriolStudy.html   (829 words)

How To Prevent Breast Cancer: Dhea Boosts Estrogen Levels They found that "estriol was very effective in improving major subjective climacteric complaints in 85% of patients, especially hot flushes and insomnia... His reasons for this are as follows: Dr. Wright found that, in some women, the amount of estriol required to relieve menopausal symptoms was as high as 1015 mg/day, and that as much as 12 mg/day were required to prevent osteoporosis. He found that some women suffered from nausea at such high doses of estriol that was severe enough to force him to cut down on their dosage level of the hormone. www.lef.org /magazine/mag96/96jan1d.htm   (1047 words)

Salivary Estriol as Risk Predictor for Preterm Labor The scientific rationale for this approach is based on the observation that a rise in salivary estriol typically occurs prior to delivery at term and prior to preterm birth. Monitoring of salivary estriol may be used as a component of the clinician's assessment of risk for preterm labor and delivery. A negative salivary estriol test resulted in a minimal change in the negative predictive value, from a baseline of 96% for the whole study population to 98% for the subset with negative tests. www.regence.com /trgmedpol/lab/lab18.html   (1525 words)

Estriol - The Friendly Estrogen   (Site not responding. Last check: 2007-10-20) Considered the friendly estrogen, research shows estriol may turn out to be the estrogen that is be an alternative for a wide array of anti-aging and hormone therapy applications, including vaginal dryness, urinary frequency, and facial wrinkles. Estriol has a very robust local effect on the many estrogen receptors in these tissues and can be useful in reducing vaginal dryness and thickening skin and mucosa in a matter of a few days or weeks. You won't find estriol at the cosmetic counter as it requires a prescription, but there are clinical studies indicating estriol cream applied regularly to the face and neck will actually reduce fine lines and wrinkles. www.womenshealth.com /estriol.html   (871 words)

Estrogen Cream for Women - CalComp Nutrition Estriol’s anti-cancer effect is thought to be due to its anti-estrone characteristics. Estriol is weaker in that it requires *2 to 4 mg of estriol to equal the effects of 0.6 to 1.25 mg of Premarin. But that is inconsequential when one considers that the more estriol a woman takes, the less likely she gets breast cancer, which is exactly the opposite of the dosage relationships of commonly used estrogens. www.calcompnutrition.com /estrogen-cream.html   (866 words)

[No title] EXPLANATION OF THE TEST Estriol (E3) is the major estrogen formed by the fetoplacental unit during pregnancy.1,2 Unconjugated E3 passes through the placenta into the maternal circulation3, where it is rapidly converted into glucuronide and sulfate derivatives to facilitate its excretion. In the procedure, estriol is conjugated to alkaline phosphatase. Expected values of estriol levels were determined by correlation of pregnancy patient serum values obtained with the Estriol (unconjugated) EIA kit with values generated from two commercially available unconjugated estriol RIA kits. www.rapidtest.com /Estriol_3171.doc   (2701 words)

Estriol ameliorates autoimmune demyelinating disease: implications for multiple sclerosis. METHODS: Estriol, progesterone, and placebo pellets were implanted in mice during the effector phase of adoptive EAE. Estriol doses that induced serum estriol levels that approximated estriol levels during late pregnancy were capable of ameliorating disease. CONCLUSIONS: Estriol as a hormone involved in immune changes during pregnancy may provide a basis for the novel therapeutic use of estriol for MS and other putative Th1-mediated autoimmune diseases that improve during late pregnancy. www.aegis.com /aidsline/1999/jul/A9970607.html   (493 words)

Estrogens It is produced in large amounts by the placenta, the tissue that links the fetus to the mother. Estriol can be detected as early as the 9th week of pregnancy, and its levels increase until delivery.

Beyond hot flashes: How the right forms of estrogen may help fight cancer, MS and more She noted the safety of estriol, and pointed out that although "estrogen" prescriptions are used much less frequently in Europe than North America, when estrogen is prescribed, it's almost always estriol. After the first three months of estriol treatment, brain scans showed the number of MS lesions in the RR group decreased by 82 percent, and the volume of those lesions decreased by 79 percent (both compared with pre-treatment scans). Estriol therapy is very safe, and, if nothing else has worked for you, it's an option you and your physician should consider exploring now. www.tahoma-clinic.com /hotflashes.shtml   (2019 words)

CYBERHEALTH 13, MAY 1998 Genistein and estriol are of great interest to women as weak estrogens that have the promise of helping to prevent breast cancer. Estriol needs to be present at about 10 times higher concentration than estradiol to have half of the estrogen receptors occupied by estriol and half by estradiol. Estriol is less readily metabolized than the other two estrogens, so this will also ultimately affect how much and what type of the three estrogens are bioavailable at any one time. www.antiaging.com /cyberhealth/CyberHealth_13.htm   (6868 words)
