Post Puberty Estrogen

"Among the routes of human exposure to estrogens, we are mostly concerned about cow 's milk,” says Davaasambuu, “which contains considerable amounts of female sex hormones." Dairy accounts for 60 percent to 80 percent of estrogens consumed according to Davaasambuu.

Is estrogen good? Is it bad? How much do I need? Understanding estrogen, the good, the bad and the ugly can be complex. Both men and women produce the hormone, estrogen. Women naturally have higher levels due to their reproductive organs and for the purpose of procreation. Estrogen is the primary source of our sex hormones and is mostly responsible for our reproductive health. Our bodies make these “good” or healthy estrogens and this is completely normal. These “good” estrogens can help to give us energy, boost our libido and protect us from certain cancers, including breast and ovarian. On the flip side, there are also “bad” estrogens or xenoestrogens, a type of hormone that mimics estrogen. Our body

in contrast to the mechanism of action of anti-estrogens such as clomiphene (Clomid) or tamoxifen (Nolvadex), which block estrogen receptors in

“Differences in sex hormone production – especially the abrupt decline of estrogen in women – are responsible for inter-gender differences in the pathophysiology of osteoporosis” (Pietschmann, Rauner et al, 2009)

Recent research has revealed that non-genomic signaling is an important mechanism for understanding estrogen's effect on the brain (Cornil et al., 2006; Losel & Wehling, 2003; Micevych & Mermelstein, 2008). Many of these actions are far too rapid to be genomic, taking place within seconds to minutes of elevated estrogen concentrations (Maggi, Ciana, Belcredito, & Vegeto, 2004; Woolley & McEwen, 1992). These effects appear to begin at ERs on the cell membrane and are important in modulation of Ca2+ channels and phosphorylation of a number of proteins, with the

Pain is experienced in many ways: physical, pain that can be chronic or acute, emotional, such as depression, or even phantom pains, which is the perception of pain in a missing limb (Jenni Ogden, 2012). Everyone feels pain in a different way. Some people perceive pain in a more intense manner than others do, while some are not as susceptible and remain unaffected. There are a few factors that go into how people bear it. Estrogen is believed lower the ability of a subject to handel pain. Transgender males to females are reported to have a heightened sensitivity to stimuli and a decrease in tolerance when faced with painful situations. The reverse is also true, transgender females to males injected with testosterone are reported to have

In conclusion, although it was always believed that the brain was mostly developed and that growth ceased at a very early childhood, through magnetic resonance imaging (MRI) we are able to observe the dramatic changes that the brain is experiencing during adolescence (Bava et al. 2010). We can observe and identify the structural change that is still occurring during adolescence and how the brain is maturing its main divisions which are the frontal lobe, parietal lobe, occipital lobe, temporal lobe, cerebellum and corpus callosum. We have discovered that the environment affects the growth and development of the brain. Hormones have an impact in the brain development because it is changing and influencing the processes of everyday living

“Although most of the breast cancers are not hereditary there are genes that determine the likelihood of getting breast cancer. This includes genes like BRCA1 and BRCA2 that can increase the risk of developing both breast and ovarian cancer” (Mandal, 2013). Furthermore, exposure to diethylstilbestrol (DES) can increase an individual’s chances of getting breast cancer. Age and height are also another risk factor. Taller and older women are more likely to be diagnosed with the disease (Mandal, 2013). Lastly, increased exposure to estrogen can cause breast cancer. Women who get their period at and young age and enter menopause at a later age are exposed to longer durations of estrogen (Mandal, 2013).

However, due to its high cost and probable side-effects, alternative therapy is now seriously being sought for. Some most recently -studied medications are isoflavones. These are phytoestrogens, i.e. plant compounds, whose phenolic ring is similar to 17β-estradiol and that can bind to the estrogen receptor with a decreased affinity (4). Results of several studies have shown the beneficial effects of isoflavones on tHcy level (5-7), although others did not observe any changes (8-11). In the case of lipid level, some studies reported favorable effect (12, 13). However, a study in Bangladesh revealed that the dietary formononetin, one specific type of phytoestrogens, had no advantageous effect in reducing CVD risks in menopausal women (11).

A critical topic in animal behavior research is to understand the physiological responses of individuals to environmental and social factors. How organisms react to a changing environment is a rising problem that is becoming a greater focus of basic research (Strier & Ziegler 2005, Wingfield et al. 2011). Field-based endocrine studies allow researchers to explore the ways in which fluctuations in the ecological and social environment are manifested physiologically (Strier & Ziegler 2005). Ecological and social endocrinology may help to better interpret and understand data on key topics such as seasonality and social and reproductive strategies (Strier & Ziegler 2005). The implementation of noninvasive techniques applied to field endocrinology

Hormones are in our food it is a FACT. Hormones should be taken out of our fast food and generic foods.Everyday society does not need to have hormones in fast food that can cause extensive obesity in our children, hormones can influence the possibility of cancer. Poor people will have an impenetrable time purchasing these foods while still having an honorable life.

Hormones are compounds produced by the endocrine system that chemically regulate specific body functions. Steroid hormones have a biochemical unique 4-ring structure, including three 6-carbon rings and one 5-carbon ring. Androgens are steroids hormones synthesized primarily in the gonads and adrenal glands. Testosterone, the key androgen, affects sexual features and development. It maintains nitrogen balance and facilitates protein synthesis (anabolism). In men, it is made in large amounts by the Leydig cells of the testes and in women, by the ovaries. The pituitary gland in the brain secretes hormones called luteinizing hormones (LH) and follicle stimulating hormone (FSH) which regulate the number of Leydig cells in the testes. Also, LH controls how much testosterone the Leydig cells produce by regulating the expression of 17-b hydroxysteroid dehydrogenase. Since this enzyme mediates the rate-limiting step of testosterone synthesis, its inhibition can stop the synthesis of. Males synthesize 2.5 to 11mg of Testosterone a day while females produce about 0.25 mg daily.

First, what is estrogen? Estrogen is a female hormone that is also produced in men, but in lower levels than women. Also known as female sex hormones, they contribute to puberty, pregnancy, menstruation, bone formation, blood clotting, maintaining the thickness of the vaginal wall as well as the urethral lining and vaginal lubrication.

Xenoestrogens are synthetic chemicals that mimic estrogen in the body. (Fertility-Health.com, 2008-2015). What is interesting about estrogen in the body is that it is present in the male and female body, but usually only associated with female hormones. Xenoestrogens disrupt hormone regulation causing a variety of health problems. It is even starting to be found in babies at birth, proving that there are outside sources of this agent getting into our bodies and causing harm (Fertility-Health.com, 2008-2015).

The SDN-POA can be enlarged in female rats through the administration of a synthetic estrogen (diethylstilbestrol) which does not bind to AFP, indicating that masculinization of this structure is dependent on the intracellular conversion of testosterone to
