Patient's question:
I have been married to my wife for many years, and we have not used any contraception, but we have never been able to get pregnant. After checking at the hospital, I learned that, please ask what are the factors that cause dead sperm.Doctor's answer:
I. Chemicals of Phthalates: Phthalates are widely used in hundreds of products such as toys, food packaging, wallpaper, detergents, lubricants, nail polish, hair sprays, soaps, and shampoos. They can affect the endocrine system, increasing the number of male sperm but reducing their motility and causing abnormal morphology. In severe cases, they can lead to testicular cancer. Nail polish contains the highest amount of phthalates, which enter the body through women's respiratory system and skin, harming the reproductive system of male fetuses they carry.II. Cigarettes and Alcohol: Nicotine in cigarettes harms sperm, reducing the concentration of sperm in male semen and increasing the ratio of abnormal sperm. Additionally, alcohol weakens reproductive function, causes chromosomal abnormalities, and leads to fetal malformations or developmental disorders.
