The Feminization of Males of Animal and Human Variety through Excess Es

The feminization of males of aquatic and mammalian species has been documented almost the world. The purpose of this paper is to review how oo estrogen in the water proviso is causing the feminization of males of animal and human variety. Natural and synthetic estrogens set about been found in the water supply, most notably in the wastewater water from waste treatment facilities. Experiments, tests and research on the effects of estrogen on mammalian and fish species has been done in the past with decisive evidence of feminization among the experimental animals. The tests were done in both lab and natural settings and included different types of fish species and mammalian species because estrogen rotter affect a wide array of species. This feminization of males can set up to be detrimental to species survival because of a skewed sex dimension and decreased sperm capabilities. Through research and tests the extent of the effects of estrogens on a be can be seen and from thes e tests suitable measures to reduce estrogen in the water supply can be made.IntroductionEstrogens atomic number 18 causing the feminization of males, especially invertebrates at an alarming rate. Estrogen is a group of steroid hormones that promote the development and maintenance of female characteristics of the body (The Free Dictionary 2011). Estrogen is found naturally in females, and males in low concentrations. Two naturally occurring estrogens are estradiol, usually referred to as E2 and estrone, referred to as E1 (Wright-Walters and Volz 2007). Not only are natural estrogens affecting the water supply, entirely synthetic estrogens are also. Synthetic estrogen is a chemical complicated created by chemical synthesis and contains estrogenic activity, however natural estrogen and s... ...eminization. Journal of Applied Ichthyology.
