Assignment 1.1: What Are Estrogen And Progesterone?

and fallopian tubes. Estrogen also stimulates the growth of the external female genitalia and breasts. Fat distribution in the female is also controlled by estrogen. The non-reproductive functions of estrogen include reduction of LDL (bad cholesterol) and an increase in HDL (good cholesterol). Estrogen also preserves bone strength by slowing down cells involved in bone break down. Estrogen concentrations in the body decrease post menopause which is why women suffer from osteoporosis later in life (Parl, 2000). Estrogen utilizes a positive feedback loop by increasing the production of gonadotropin releasing hormone in the hypothalamus which then increases the release of FSH and lutenizing hormone. This increase in FSH and LH prepare the uterus

Cholesterol carries lipid in your blood. Lipids is a fatty tissues found in the membrane of the body tissues, it is a source of fat. It is transported in the blood plasma of the body.

Cholesterol is a waxy, fat like product found in cells throughout your body. It helps in building hormones like estrogen, progesterone, testosterone, and in the production of cortisol, the stress hormone. Cholesterol also helps the body in the absorption of vitamins A, D, K, and E. Although your body produces some cholesterol, it is found in many of the foods you eat.

Are you currently faced with the onset of menopause? Do you wish there was more information available on how to stay healthy during this dramatic changing phase in your life? Congratulations! You have found the answer source for your hesitant questions regarding menopause. You are probably not alone in your quest; the American College of Obstetrics and Gynecologists (ACOG) believes that over one-third of the women in the United States are over the age of 50 (http://members.aol.com/dearest/October.htm). The onset of menopause in women from the Baby Boomer generation- those born after World War II- is increasing rapidly (Samisioe,1992).

Testosterone belongs to a class of male hormones called androgens that is vital for sexual and reproductive development. The National Institutes of Health regards “testosterone as the most important male hormone”(Rettner). Although the primary role of testosterone directly relates to males, women also produce testosterone at lower levels. Women’s total levels are about a “tenth to a twentieth of men’s levels”(Rettner). According to the Mayo Clinic, this hormone plays a role in sex drive, sperm production, fat distribution, red cell production, and maintenance of muscle strength and

Also, estrogen can have a favorable impact on cholesterol and a positive effect of estrogen on cholesterol values with issues of estrogen maintenance with health risks. Many individuals decide to use tamoxifen to fight estrogenic side effects; when using steroids for long periods of times (What are Steroids).

Estrogen and progesterone are hormones generated by the ovaries. These hormones have a variety of fundamental uses in the body of a female. Estrogen initiates thickening of the uterus wall in preparation for implantation of a fertilized ovum. Also, estrogen plays a role in the metabolism of calcium in the body. Apart from these two roles, estrogen also participates in the maintenance of cholesterol levels within the normal limits. Estrogen is also implicated in keeping the vagina healthy. Progesterone, on the other hand, acts as a regulatory substance to estrogen. Menopause is characterized by a reduction in production of these hormones. This decline in production correlates with a decline in performance of

There are many factors to boosting testosterone, and most of it all comes down to the two main issues of "we are what we eat" and "use it or we lose it". This means that like any great chef must have the right ingredients in order to prepare the greatest meal, our body needs the right ingredients or foods in order for it to create, make or produce testosterone. The key ingredient is cholesterol and there are many stages to its production where the testes break down the cholesterol into other types of hormones and compounds first before finally arriving at the finished product - testosterone. However, within this metabolic process of breaking down the cholesterol, the body also needs other microscopic quantities of essential minerals and compounds

Our body naturally produces cholesterol through the liver, we can also obtain cholesterol from consumed products. We need small amounts of cholesterol to produce hormones, bile, and vitamin D. Cholesterol doesn’t dissolve in the bloodstream once it is inside the body. It needs to be carried by two types of lipoproteins called low density lipoproteins(LDL) and high density lipoproteins(HDL). The more cholesterol we consume, the more LDL and HDL we produce. HDL is

Estrogen is a steroid hormone which plays a crucial role in growth and maturation of both sexes. In the female reproductive system, estrogen targets tissues such as mammary glands, uterus, and ovaries. Bone formation has a significant positive relationship with estrogen from puberty to maturation and beyond (Clark et al., 1992). Post puberty estrogen is mainly synthesized and released from the ovaries in females. Through binding proteins or estrogen receptors (ER) found within the nucleus, estrogen is retained and affects specific target tissues throughout the body. Binding of estrogen to its receptor causes conformational change which in turn allows binding to chromatin and proceed with transcription of specific target genes (Murdoch

(D) The structures of the steroid hormones GR, MR, AR, PR and ER are shown with numbering of the rings and the key atoms. (Taken from: 1)

I mean the drugs that can cause excessive accumulation of fluid in the area of the men nipples without estrogens. This is primarily oksimethalon.But let's go back a bit and talk about the following. Is it possible that the level of estrodiol in the blood of a men will rise even with a short-term use of steroid drugs? No it is not possible. As with any side effect, this defect requires prolonged use or overdose.And the last thing I would like to discuss - each person has an individual reaction to the estrogens in the blood because we are all different as banal as it may sound, some people even have immunity to the process of aromatization, and some on the contrary may be particularly inclined to this problem.Restoring the natural balance.Lets finish with the theory and go back to what we actually started with and what I wanted to tell you about, that is to anti-estrogens. It is a mistake to assume that anti-estrogen is a drug created specifically for men, as if it was created to suppress the development of the feminine in men. The situation is quite opposite, originally anti-estrogens were created for women who had problems with an excess of estrogen in their bodies. For example, particularly large

“Atherosclerotic coronary arterial obstruction is when there’s a build-up on the walls of the coronary arteries. This build-up of plaque or fatty deposits are called atheroma, it’s made up of cholesterol particles and other waste substances in the blood, which then begins to accumulate on the walls of the arteries that supply blood to the heart”[II]. ‘Cholesterol is a fat made by the liver from the saturated fat in your diet. Cholesterol is essential for healthy cells”. [IV] “Cholesterol is carried in the bloodstream by molecules called lipoproteins. There are several different types of lipoproteins, but two of the main ones are low-density lipoproteins (LDL) and high-density lipoproteins (HDL)” [IV]. These break up into particles and start to get imbedded to the walls of the arteries.

There are many risk factors which facilitate the development of atherosclerosis; abnormal blood lipids are just one of them. Blood lipids consisted of three components including cholesterol, triglycerides, and two major forms of lipoproteins: high density lipoproteins (HDLs) and Low density lipoproteins (LDLs). One of the critical components which determine the degree of blockage on the arterial walls is the quantity of cholesterol
