  Plasticizer is causing male infertility: Phthalates are a class of plastics used in the main plasticizer and  PVC processing aid flexible agent, because all kinds of plastic packaging fast food appeared in large numbers, making contact with people on the plasticizer opportunities have increased significantly. After 10 years of research found that phthalates in plastics plasticizer may be the cause behind male infertility. In animal experiments, we gave mice fed plasticizers and found decreased testis weight, smaller size, and degenerative changes in testes appeared decreased sperm count, sperm deformity rate increased. In certain doses, associated with the heat stabilizer for pipe  two kinds of plasticizers used in mouse bone marrow micronucleus and sperm abnormality test results were positive. This shows that the plasticizer is a heritable cause chromosomal aberrations cleavage agent. Plasticizers body excretory phase current is not clear if the daily intake, it is easy to accumulate in the body, resulting in toxic effects. In order to reduce the exposure of childbearing age youth plasticizer, we recommend that antimony flame retardant  young people of childbearing age to take the following self-protection measures: ① eat instant food in plastic packaging. ② not directly heated plastic packaged foods (such as bags of milk). ③ not in plastic food storage container and heated in a microwave. ④ without plastic bags placed hot fritters, cakes, Gao, hemp groups, and other fried fried foods. ⑤ the roadside food vendors to provide colorful small plastic bag shut. ⑥ strict implementation of 1 June 2008 China began to implement the plastic limit. This is not only beneficial to protect the environment, maintain the ecological balance, and help reduce the health hazards of plasticizers, especially for childbearing potential threat to the male reproductive capacity.
