The percentage of forward motion of sperm is 19%, suggesting that it belongs to weak spermatozoa, and the probability of partner’s conception is lower than normal, but there is a chance of pregnancy. In the normal process of conception, sperms have to pass through the female reproductive tract, uterus and fallopian tubes to reach the ovaries and meet with the egg in order to fertilize, so only forward-moving sperms can meet with the egg and fertilize it, and the more forward-moving sperms, the higher the probability of conception. Current diagnostic criteria, forward-moving sperm percentage greater than 32% is considered normal. Men are advised to avoid bad habits that lead to decreased sperm motility, such as irregular lifestyle, sedentary lifestyle, etc. They should also be careful not to smoke or drink, wear tight jeans for a long period of time, and avoid high temperatures and radiation-inducing work environments. If a man has a spermatozoa forward motion percentage of 19%, it is recommended that he seek medical attention in a timely manner, under the guidance of a doctor, complete the relevant examinations, identify the cause of the disease, and treat the symptoms.
