Male Infertility

Sperm Motility

Poor Sperm Motility Treatment

Sperm motility describes the ability of sperm to move properly through the female reproductive tract to reach and fertilize the woman’s egg.

While the most common cause of male factor infertility is low sperm count, some men are infertile because of poor sperm motility. Normally, at least 50% of a man’s sperm should have good quality progressive motility. When levels are below this percentage, the condition is called asthenospermia or asthenozoospermia. Many men with low sperm count will also have poor sperm motility issues. However, some men can have a normal sperm count but very poor sperm motility.
