Nicotine in cigarettes can kill sperm, cause sperm dysplasia, increased the proportion of deformed and defective sperm, and can even cause the sperm chromosome to sudden mutation, causing changes in genetic genes.Too much smoking can also cause increased thiocyanic acid in semen, thereby suppressing the mobility of sperm.The survey found that the longer the smoke age, the greater the amount of smoking, the less sperm, the higher the deformed rate of sperm, and the lower the ability of sperm activity.If you are preparing to be a healthy baby, it is best to quit smoking from three months to half a year before the plan to conceive.
Alcohol has a strong poisoning effect on reproductive cells, which can damage sperm and affect the development of the embryo.Long -term drinking can cause decline in male fertility.It has been proven that alcohol can slow the synthesis of testosterone, affect the normal metabolism of testosterone, cause low reproductive gland function, affect the production of sperm and the quality of semen.Some people in Western countries like to drink alcohol. They often drink drunk on Sunday. Babies born in pregnancy after the same room at night are called "Sunday Babies".These babies are often weak, dysplasia, and even deformity or dementia.Therefore, it is best to drink less or not even drink less than two or three months before planning to ensure the quality of sperm.Men's excessive drinking can also cause or temporarily incompetence.
