In order to further illustrate the complexity of the estrogen environment, listed below are many positive results of estrogen use. How many of the items listed below have you learned about?

1. A new study has found that women who have their ovaries removed (which stops estrogen production) increase their chances of coronary heart disease, stroke, breast cancer, ovarian cancer, lung cancer, colorectal cancer, total cancers, hip fracture, pulmonary embolus, and death from all causes.
2. Hormones produced by the ovaries keep the heart, bones and blood vessels healthy.
3. Data analyzed on 2,050 people between 1997 and 2004 have indicated that there is growing evidence that estrogen protects against colorectal cancer.
4. Research indicates that women taking postmenopausal hormone therapy reduced the risk for colorectal cancer by about 40%.
5. There is a study that revealed that estrogen deficiency causes bladder hypersensitivity.
6. Estrogen users perform better on memory tests than non-users.
7. Studies are being conducted because evidence indicates that estrogen may prevent Alzheimer’s disease.
8. Research indicates that estrogen promises new hope to both men and women who suffer from the symptoms of schizophrenia.
9. A study revealed that estrogen therapy seems to protect against brain damage for women in their late 40s and 50s.
10. There is evidence that hormone therapy may help protect older women against age related blindness.
11. A study published in the Journal of the American Medical Association stated that men with heart failure who had the lowest levels of estrogen had about four times the risk of dying as men with average levels.
12. A recent study revealed that estrogen strengthens women’s immune systems.
13. Estrogen therapy can help control metastatic breast cancer as reported by the results of a study through the National Cancer Institute. “About 40,000 women die of metastatic breast cancer each year, and estrogen therapy potentially could help thousands of women with hormone receptor-positive disease,” says Matthew Ellis, M.B., Ph.D., associate professor of medicine at Washington University School of Medicine in St. Louis.
14. Dr. Delfin Tan, International Menopause Society board member, states “Estrogen affects many target organs through a variety of estrogen receptors in diverse tissues,” he says. “This causes changes in the brain, eyes, heart, breast, vasomotor system, colon and urogenital tract.” Also, Dr. Tan lists osteoporosis, atherosclerosis, coronary heart disease, cerebrovascular disease, and Alzheimer’s disease as the late effects of estrogen deficiency.
