Does poor sperm quality affect children?

Patient's question:

Does poor sperm quality affect the development of the baby in the future? My husband never pays attention to his diet and always smokes. During our pre-marital health check-up, we found that his sperm quality was very poor, but we didn't pay much attention to it at the time. Now I haven't had my period for two months, and the morning test results showed that I'm pregnant. However, the previous check-up indicated that my husband's sperm quality was poor, and I'm very worried it will affect the baby's development. Please ask if poor sperm quality will affect the baby's development in the future?

Doctor's answer:

Hello, abnormal sperm can have a certain impact on fertility. Even if pregnancy occurs, the quality of the fertilized egg may be poor, leading to issues like miscarriage. Under normal circumstances, sperm viability should be greater than 70%. However, poor sperm quality only affects embryonic development to a certain extent.
Advice: Some people may still have healthy children in this situation, which also depends on the mother. If the mother is healthy and takes good care of herself, with regular check-ups, the child will also be healthy.
