What are the ways for men to protect their sperm?

　　Data show that in the past 50 years, male sperm The number is gradually decreasing. Research by Rafe Doherty of Florida State University found that the sperm count of American men has dropped by almost one-third compared to the past. The median sperm count in 1929 was 90 million/ml, while in 1979 the median was 60 million/ml. Professor Doherty recently surveyed 132 male college students and found that 23% of them had a sperm count of less than 20 million/ml.
　　
　　Vulnerable sperm
　　
　　From the perspective of sperm biological characteristics, sperm is the terminal product of the development of the male germ cell line. During the process of spermatogenesis, formation and deformation, due to the escape of cytoplasm, DNA repair enzymes in the cytoplasm are lost, resulting in the loss of DNA damage and repair system functions. Therefore, it cannot repair more than 90% of the damage to primary genetic material by itself like somatic cells and egg cells. In addition, sperm are more sensitive to toxic substances than various other cells.
　　
　　In the rapid process of spermatogenesis, the harmful effects of various harmful factors increase significantly after accumulation and accumulation. With the deepening of research and understanding of genes in recent years, it has become clearer that compared to the X chromosome, the genes carried by the Y chromosome are more prone to mutations.
