Which determines the baby's health, sperm or egg?

Sperm quality affects the fetus, which is the final form of fertilized egg division, growth and development, and the result of sperm-egg combination. Therefore, the influence of sperm quality on fetal health is very important. If the sperm activity in male semen is relatively low, the survival rate is not up to standard, and the quantity is not enough, it may lead to the mother's easy abortion during pregnancy and affect the fetal survival rate.
