What is Sperm Motility? — Altora Health

Quick Definition: The definition of motility is the ability of an organism or fluid to move. Sperm motility refers to the movement and swimming of sperm. Poor sperm motility is also known as asthenozoospermia. Sperm are motile cells. This means that they are cells that make themselves move. This is important when it comes to getting pregnant. Usually, when a man and woman have vaginal sexual intercourse, the man will ejaculate semen near the cervical canal, at the end of the vaginal canal.
