Estrogens are a group of steroid hormones that recently have gained even more attention in the eyes of scientists. There is an ongoing discussion in the scientific community about their relevance as environmental contaminants and the danger they pose to animal health and welfare.
In available literature we can find many examples of their negative effects and mechanisms that are involved with such phenomena. Nowadays, there is a growing interest in environmental pollution; however, knowledge about this aspect is growing at an insufficient pace.
There are many potential sources of environmental contamination, including sex hormones—especially estrogens. The analyzed literature shows that estrone E1estradiol E2estriol E3and synthetic ethinyloestradiol EE2 are the most ificant in terms of environmental impact. Potential sources of contamination are, among others, livestock farms, slaughterhouses, and large urban agglomerations. Estrogens occurring in the environment can negatively affect the organisms, such as animals, through phenomena such as feminization, dysregulation of natural processes related to reproduction, lowering the physiological condition of the organisms, disturbances in the regulation of both proapoptotic and anti-apoptotic processes, and even the occurrence of neoplastic processes thus drastically decreasing animal welfare.
Unfortunately, the amount of research conducted on the negative animale sex games of their impact on animal organisms is many times smaller than that of humans, despite the great richness and diversity of the fauna. Therefore, there is a need for further research to help fill the gaps in our knowledge.
