How does estrogen affect your brain?
It is thought that estrogen affects how your brain structures are connected, how your brain cells communicate, and even the shape of your brain. Additionally, estrogen plays a big role in your mood because it has a very strong effect on a brain chemical called serotonin. Serotonin is a mood-balancing chemical and estrogen promotes its production. That means when your estrogen level is low, your serotonin level will decrease as well. The effect of this is very significant in some women. It is thought that this low estrogen -related drop in serotonin production contributes to postpartum and menopausal depression. 1

Why did the Women's Health Initiative end?
The Women's Health Initiative ended clinical studies prematurely because participants in the study developed an increased risk of breast cancer and coronary artery disease .[2] Newer studies contradict the finding of the Women's Health Initiative, with evidence of improved quality of life and reduced risk of coronary artery disease and osteoporosis in women when women start estrogen hormone replacement therapy at the onset of menopause.[3] The FDA has approved estrogen for hormone replacement therapy in the treatment of symptoms of menopause. Synthetic estrogen is also available for clinical use, designed to increase absorption and effectiveness by altering the estrogen chemical structure for topical or oral administration. Synthetic steroid estrogens include ethinyl estradiol, estradiol valerate, estropipate, conjugate esterified estrogen, and quinestrol. Ethinyl estradiol is a commonly used synthetic estrogen to prevent pregnancy as a component of the oral contraceptive pill approved by the FDA.[4] Some nonsteroidal synthetic estrogens include dienestrol, diethylstilbestrol, benzestrol, methestrol, and hexestrol.

How does estrogen affect the body?
Like other steroid hormones, estrogen enters passively into the cell where it binds to and activates the estrogen receptor. The estrogen:ER complex binds to specific DNA sequences called a hormone response element to activate the transcription of target genes (in a study using an estrogen-dependent breast cancer cell line as model, 89 such genes were identified). Since estrogen enters all cells, its actions are dependent on the presence of the ER in the cell. The ER is expressed in specific tissues including the ovary, uterus and breast. The metabolic effects of estrogen in postmenopausal women have been linked to the genetic polymorphism of the ER.
Where is estrogen expressed in the body?
The ER is expressed in specific tissues including the ovary, uterus and breast. The metabolic effects of estrogen in postmenopausal women have been linked to the genetic polymorphism of the ER.
What are the four types of estrogens?
The four major naturally occurring estrogens in women are estrone (E1), estradiol (E2), estriol (E3), and estetrol (E4) . Estradiol is the predominant estrogen during reproductive years both in terms of absolute serum levels as well as in terms of estrogenic activity. During menopause, estrone is the predominant circulating estrogen and during pregnancy estriol is the predominant circulating estrogen in terms of serum levels. Given by subcutaneous injection in mice, estradiol is about 10-fold more potent than estrone and about 100-fold more potent than estriol. Thus, estradiol is the most important estrogen in non-pregnant females who are between the menarche and menopause stages of life. However, during pregnancy this role shifts to estriol, and in postmenopausal women estrone becomes the primary form of estrogen in the body. Another type of estrogen called estetrol (E4) is produced only during pregnancy. All of the different forms of estrogen are synthesized from androgens, specifically testosterone and androstenedione, by the enzyme aromatase .
What receptors do estrogens bind to?
Additionally, estrogens bind to and activate rapid-signaling membrane estrogen receptors (mERs), such as GPER (GPR30).
How is estradiol metabolized?
Estrogens are metabolized via hydroxylation by cytochrome P450 enzymes such as CYP1A1 and CYP3A4 and via conjugation by estrogen sulfotransferases ( sulfation) and UDP-glucuronyltransferases ( glucuronidation ). In addition, estradiol is dehydrogenated by 17β-hydroxysteroid dehydrogenase into the much less potent estrogen estrone. These reactions occur primarily in the liver, but also in other tissues .
What is the name of the hormone that is produced during pregnancy?
Another type of estrogen called estetrol (E4) is produced only during pregnancy. All of the different forms of estrogen are synthesized from androgens, specifically testosterone and androstenedione, by the enzyme aromatase .
Why do women have less heart disease?
Women suffer less from heart disease due to vasculo-protective action of estrogen which helps in preventing atherosclerosis. It also helps in maintaining the delicate balance between fighting infections and protecting arteries from damage thus lowering the risk of cardiovascular disease.
