Moderate weak spermatozoa may be caused by bad habits, endocrine disorders and varicocele, etc. Patients can be treated by improving their habits, taking medication or surgery. 1. Bad lifestyle habits: If you stay up late, smoke and drink a lot, the quality of your sperms may decline, which will eventually lead to weak spermatozoa. If you go to bed early and get up early, quit smoking and drinking, do proper exercise and improve your immunity, moderate spermatozoa may be alleviated. 2. Endocrine disorders: Endocrine disorders are one of the main causes of moderate spermatozoa. If you are often overly anxious and busy because of work and life, it may cause the body to develop endocrine disorders, resulting in immature sperm development, which ultimately affects the vitality and quantity of sperm, and the symptoms of moderate sperm weakening appear. Normally, you should pay attention to the combination of work and rest, relaxation, if necessary, through the glutamine to regulate. 3. Varicocele: If the patient has varicocele, due to the obstacle of blood circulation in testicles and epididymis, the local temperature rises and metabolic substances accumulate, which may lead to the appearance of moderate spermatogenesis. Patients can have spermatic vein ligation, which can effectively improve the blood supply to the testicles and improve fertility to a certain extent. Patients with moderate weak spermatozoa should avoid smoking and alcohol abuse in daily life, exercise and develop good habits, and go to the hospital if necessary for treatment under doctor’s guidance.
