Mild spermatorrhea is caused by insufficient sperm motility or reduced sperm count. 1. Insufficient sperm vitality: mild hypospermia can be caused by congenital factors, endocrine abnormalities or infections, etc. Suffering from this disease will lead to a decrease in sperm motility, in which case, the ability of sperm to penetrate the egg cell will be reduced, so that the sperm and the egg cell can’t be combined properly, resulting in the failure of women to get pregnant normally. 2. Reduced sperm count: Mild hypospermia can also be caused by a low sperm count. After suffering from this disease, the number of sperms in the patient’s semen will be significantly reduced. Patients with microzoospermia usually do not have other obvious symptoms, if there has been a failure to conceive the situation, you should go to the hospital in time to receive treatment.
