Sometimes 0% sperm morphology results may occur and pregnancy chance is thought low. Sperm morphology is not the single factor about pregnancy, sperm cell contains the features for fertilization inside and these factors are activated when sperm cell meets the egg. Only sperm morphology result is not enough to say that you can’t get pregnant naturally. Other factors should be evaluated to see the pregnancy chance.
