Most of them recommend eating nutritious food, vegetables and fruits to improve sperm quality. The male spermatogenesis cycle is generally three months. Most men need to quit smoking and drinking three months before pregnancy, pay attention to the regular work and rest, do not stay up late, and generally go to bed early and get up early. Regular life will be better, and sexual life can not be frequent, which can improve the quality of sperm. If you do have oligospermia, asthenospermia, and azoospermia, if you want to take medicine to improve the quality of sperm at this time, you must go to the hospital, find out the situation of regular semen abnormalities according to the situation, and then choose the appropriate medicine to correct the symptoms.
