Hemospermia is not an uncommon disease and may affect the sperm motility. But the research about sperm motility in hemospermia is rare. So we studied the change of sperm motility between control group and patients with hemospermia and also studied the change of sperm motility between patients with hemospermia and those whose hemospermia was improved, the change of sperm motility between control group and artificially induced hemospermia group. We observed that the sperm motility in patients with hemospermia was decreased than that of control group, and that, as hemospermia being better, sperm motility was improved. We also observed that sperm motility in artificially induced hemospermia was decreased. The results provide that hemospermia has an effect on decreasing hemospermia motility.
