It is possible for a man to get pregnant with insufficient sperm motility. Higher sperm motility in men can only mean that the success rate of pregnancy will be higher. A man’s lack of sperm vigor does not mean that there is no normal sperm. Sperm vigor is a percentage, and there are many sperm with poor vigor as well as many sperm with better vigor, and only one sperm with very good vigor is needed for a pregnancy. These sperms combine with the egg in the woman’s body and it is possible to form a fertilized egg. It is recommended that men with insufficient sperm motility should have regular sexual intercourse and should also undergo effective tests to find the cause of insufficient motility and treat the primary cause effectively. Pay attention to check whether there is varicocele, whether there is prostatitis and so on.
