It is possible to get pregnant with grade A fast forward moving sperm 2.7. As long as there are A-class rapid forward-moving spermatozoa, pregnancy is possible. However, when the proportion of A-class rapid forward-moving spermatozoa is low and their number is small, the pregnancy rate will be reduced accordingly, which is clinically called weak spermatozoa, and if their proportion is increased and their number is large, the pregnancy rate can be improved relatively. For the evaluation of sperm quality, in addition to the number of forward-moving sperm, it is also necessary to refer to the sperm deformity rate, sperm density and other multiple indicators to make a comprehensive judgment. Men can also improve their sperm quality by exercising, resting and eating well before pregnancy, and if they encounter severe oligozoospermia or even azoospermia, they can seek assisted reproduction to help them conceive.
