I heard that the diagnostic criteria for weak spermatozoa have been adjusted downward. Weak spermatozoa refers to low sperm motility, with less than 25% of A-grade sperm or less than 50% of A+B-grade sperm, but of course this cannot be generalized, and it cannot be said that a patient cannot get pregnant if he does not meet this criterion, but it should be understood that the smaller the percentage, the less likely he is to get pregnant. On the contrary, the higher the percentage. Clinically, weak spermatozoa can only be considered a relative infertility. The female partner should be actively examined for the cause. Regarding the treatment of weak spermatozoa there is no single drug that is significantly effective for all weak spermatozoa. Specific treatment can only be individualized according to different patients. In clinical practice even the results of the methods recommended by many well-known experts in Beijing are rarely effective. So never be superstitious. I prefer to combine Chinese and Western medicine for individualized treatment. Commonly used drugs are levocanidine, pancreatic kininogenase, coenzyme Q10, chorionic gonadotropin, urotropin, etc.
