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

To grow and reproduce, breast cancer cells require the female hormone estrogen. Tamoxifen is an "anti-estrogen" and works by competing with estrogen to bind to estrogen receptors in breast cancer cells. Tamoxifen is formally known as a selective estrogen receptor modulator (SERM). By blocking estrogen in the breast, tamoxifen helps slow the growth and reproduction of breast cancer cells. While tamoxifen fights estrogen in breast cancer cells, it also mimics the positive effects of estrogen in other body systems. Post-menopausal women who take tamoxifen may decrease their risk of heart disease or osteoporosis (a degenerative bone disease) without having to use hormone replacement therapy (HRT ).

Breast cancer is a leading cause of death of women, secondary only to heart disease. Breast cancer will affect one of every eight women or approximately 12% of the population. In 2016 there are 246,660 new cases of invasive breast cancer that will be diagnosed as well as 46,000 cases of breast cancer in situ in women. Additionally, there are 2,600 cases of breast cancer that will be found in men. Breast cancer rates have been decreasing since the year 2000. This is thought to be partially due to increased screening measures as well as discontinuing the use of hormone replacement therapy. There was as positive link established between hormone therapy

Breast cancer is a popular disease that many people are afraid of. It is the growth of altered genes that create malignant tumors starting in a female or male’s breast tissue. Cancer has a reputation of being caused by hormones, but that may not always be the case. Hormones are chemicals that work as chemical messengers in the body and affect the duties of cells and tissues. The ovaries in premenopausal and postmenopausal women usually produce the hormones, like estrogen and progesterone. The hormone estrogen develops and maintains the female sex features and progesterone have to do with women 's menstrual cycle and pregnancy. In a breast cancer cell, it

• For example in one single run all the mono-amines like dopamine, epinephrine, serotonin can be estimated. Single run for steroids in one sample gives the data of all the steroids in that sample.

In the early years of anabolic steroid development, there was no standardized test method for different steroids or the method of measuring their strength. Hershberger Assay was introduced in 1960 to solve this problem. After administration of the steroid test, various parts of the body and muscles were analyzed in the rat. Since testosterone was considered the standard for testing, the tissue would be compared to the tissue exposed to testosterone. Levator is not the muscle in rats that control the movement of the skin. The muscles were analyzed after the rat had a steroid. Increasing the muscle mass and body weight of the

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

With menopause estrogen defiency occurs which is associated with increased severity and incidence of OA in women. Estrogen therapy reduces the risk of OA compared to those who are not taking it.(21)

Estrogen treatment: Estrogen-related drugs are sometimes used in hormonal therapy of men with prostate cancer. This treatment may cause a slight increase in breast cancer risk. However, this risk is small compared with the benefits of this treatment in slowing the growth of prostate cancer. Men taking high doses of

Since breast tissue is very sensitive to this mistaken estrogen, it tricks the cells and causes breast cell division because more than half of all breast cancer tumors rely on estrogen to function.

Eradication of cancer is one of the key challenges for medicine in the 21st century, breast cancer being the most common type of cancer in women, worldwide (Arteaga and Baselga, 2012, Vidal et al., 2012 and Weinstein et al., 1997).Breast cancers are classified on the basis of expression of hormone receptors i.e., Estrogen receptor, Progesterone receptor and HER2. The subtypes are as follows:

Spermatocytogenesis is the male form of gametocytogenesis and results in the formation of spermatocytes possessing half the normal complement of genetic material. In spermatocytogenesis, a diploid spermatogonium which resides in the basal compartment of seminiferous tubules, divides mitotically to produce two diploid intermediate cells called primary spermatocytes. Each primary spermatocyte then moves into the adluminal compartment of the seminiferous tubules and duplicates its DNA and subsequently undergoes meiosis I to produce two haploid secondary spermatocytes, which will later divide once more into haploid spermatids. This division implicates sources of genetic variation, such as random inclusion of either parental chromosomes, and chromosomal crossover, to increase the genetic variability of the gamete.
