Metal is an indispensable important material in human production and life.According to the current research, there are a variety of heavy metals that affect the human reproductive system. Among them, the more common heavy metals are lead, mercury, manganese, and cadmium.
Lead can directly act on testicles
As early as the ancient Roman period, there were severe contamination of lead, especially in the Roman Empire aristocratic class to add lead Dan to increase the sweetness of grape juice and alcohol, thereby leading to lead poisoning, which led to a general decline in fertility and inferiority.Therefore, some people have proposed that the decline of the Roman Empire may be related to the low fertility ability and the decline in the population quality of the Roman layer.
Lead can directly act on the core organ of the male reproductive system & mdash; & mdash; testicles.The author has analyzed the semen content of 38 lead operators and found that the average lead in semen is 3.2 microre per liter per liter, which is not only significantly higher than 0.8 microl per liter of non -contact persons, but also significantly higher than engaged in lead leaders.The average blood leader of the operator itself is 2.3 microl.It shows that lead can indeed enter the semen through blood-test barrier, and has a certain accumulation effect.Lead can also indirectly affect the reproductive function of men by blocking the regulatory function of the hypothalamus-pituitary = testicular axis, thereby affecting the secretion of reproductive hormones, such as significantly reduced testosterone.
