Research on the Effects of Japanese Quails Exposure to Synthetics Hormones

Synthetic estrogens such as ethinyl estradiol and diethylstilbestrol are injected into fertilized eggs. Those treated with diethylstilbestrol synthetic hormone are introduced into male testosterone. After hatching, put all the birds in a separate cage. All males are equipped with female recessive counterparts. We observe sexual activity in the cage for about 2 minutes. Subsequently, blood samples were taken from all males to determine testosterone levels when observing mating behavior.

There are natural hormones and synthetic hormones. Natural hormones are produced by organs of the body and transported to the target site in the bloodstream to regulate physiological responses such as growth, development, reproductive. Synthetic hormones, on the other hand, are used to mimic the effects of their natural counterparts. Diethylstilbestrol (DES) and hexostrol are examples of a group of estrogen producing terpenes used in the United States (1950's) and Hong Kong's poultry production. Since stilbene is a protein hormone, it is broken down after ingestion and becomes nonfunctional, so it is necessary to administer it by frequent injection or implantation of subcutaneous particles such as diethylstilbestrol.

Over the past decade, people have begun to focus on the risks associated with synthetic hormone replacement therapy (HRT) for the treatment of menopausal disease and related diseases. These synthetic hormones contain hormones incompatible with hormones in the human body, including estrogen in equine urine. In 2002, the Women's Health Initiative (WHI), sponsored by the US government, published a study showing the relationship between HRT and increased risk of breast and uterus cancer, heart disease, stroke and dementia. (9) The study covered 16,608 healthy postmenopausal women with a 50 to 79 year old uterus randomly assigned to either the experimental group or the placebo group. The test group received a combination of synthetic hormones and did not receive the placebo group

Mifepristone is a synthetic steroid with anti-progesterone and anti glucocorticoid action. It is used to stop pregnancy and to treat patients with Cushing's syndrome. Progesterone is female hormone and major progesterone. Preparation of progesterone The uterus (uterus) is an important hormone for receiving and maintaining fertilized eggs and maintaining pregnancy. Mifepristone terminates early pregnancy by blocking the progesterone activity of the progesterone receptor. It also stimulates uterine contractions. It is thought that it is 49 days (7 weeks) from the last menstruation in the early pregnancy. Mifepristone should be combined with misoprostol to end pregnancy. The FDA approved this combination therapy in September 2000.
