Sperm motility of 43.8% is a sign of low sperm motility and weak spermatozoa in men. It cannot be treated with food, but it can be treated with physiotherapy, medication and surgery. 1. Physical therapy: The most common causes of low sperm motility include varicocele and sedentary lifestyle, which lead to high temperature in the scrotum, which can be relieved by wearing scrotal support underwear. 2. Medication: Commonly used medications include levocanidin and vitamin E, which can improve the problem of low sperm motility. 3. Surgery: Surgery can be used to treat decreased sperm motility caused by severe varicocele. Generally speaking, a sperm motility rate higher than 70% is normal. Decreased sperm motility is an important factor leading to male infertility. When the sperm motility is lower than 70%, the fertility can be reduced, and if it is lower than 40%, it can lead to infertility. It is recommended that patients need to consult a doctor in a timely manner, after clarifying the cause of the disease, timely treatment, do not use private medication, so as not to cause danger.
