Environmental pollution has one type of "environmental hormone", also known as "hormone -like" and "endocrine interference substances". It is a chemical with estrogen -like estrogen characteristics in the environment.After entering the human body, they will act on multiple aspects of sperm development, leading to decreased sperm development malformation, quantity and quality, greatly reduced female conception, and even lost their fertility.
There are many types of pollutants containing environmental hormones. They mainly exist in pesticides, fertilizers, pesticides, detergents, plastic products, plasticizers, asbestos, chemicals, automobile tail gas, waste incineration gases, certain heavy metals, and cosmetics.EssenceAmong more than 200 compounds that people often come into contact with, more than 60 % have irreversible toxicity to sperm, and more than 20 professional poisons can also harm sperm.
Due to the increasingly serious environmental pollution, the number of men's semen has been reduced by half in the past 50 years.The acute or chronic poisoning caused by environmental pollution can reduce the activity of enzymes in the testicular, affect the process of sperm, increase the proportion of deformity sperm, and its vitality, penetrating power, and the pregnancy rate are declining.
High -incidence people engaged in radioactive work, high -temperature operations, and long -term contact with toxic substances such as paint, coatings and mercury, lead, and phosphorus are all high -incidence people.The proportion of fertility is about 40 % of the sperm quality and quantity loss.
It can be said that environmental pollution is the first killer of sperm.It has a greater threat to humans: it is latent, durable, and irreversible, and it is not easy for people to perceive its harm in a short time (several years, ten years).
