    Glossary Sperm Motility

    ability of sperm to swim effectively toward an egg

    Sperm motility refers to the ability of sperm to move efficiently, which is crucial for fertilizing an egg. This movement is typically assessed in terms of the percentage of moving sperm and the quality of their movement, including speed and direction. Poor sperm motility can be a factor in male infertility.
