The Feminization of Males of Animal and Human Variety through Excess Estrogen in the Water Supply

In this article, we use women's influence on invertebrates and fish as a concrete example. This is more prominent than mammals. Since estrogen lives and grows directly in contaminated water, it affects fish. In natural environment, fish will make more serious feminization. If the concentration of estrogen is too high, terrestrial animals begin to be women in wild. Many species of fish are ideal for estrogen effect experiments due to their fast life span.

BPA is an isoestrogen, also known as endocrine disrupter (EDC), which mimics hormone estrogens. EDC has various effects on humans and wildlife. For example, fish and other aquatic wildlife may become feminine. Male frogs not only look like females, they actually have other male and viable offspring. In this case all descendants are males and it is very difficult to keep breeding. Similarly, men may not be suitable for reproductive reasons, as there are few or no features of men contributing to breeding. EDC can cause many other problems, many of which are also carcinogenic

Endocrine disrupters are synthetic chemicals that mimic human hormones, especially estrogens. They are diverse, becoming a disaster of ecology and health everywhere in the environment. Estrogen mimetics are particularly harmful to male sexual development. With fish, men can be women. In frogs, they prevent male sexual maturity; in mammals such as us, they cause abnormal sperm development and infertility. As mentioned above, imprinted genes are particularly susceptible to endocrine disruptors, and these effects may be transmitted beyond generations. In an important study on mice, the fungicide Vinclozolin has been shown to be a powerful endocrine disrupter that causes various problems including sperm defects in exposed female mice. The most worriing thing is that even if they have never been exposed to vinclozolin, the next three generations are also infertile.
