About

Is my sperm motility normal? The best answer comes from the world health organization, which reports worldwide measures of semen parameters. The who reports motility only in percentage, so it is difficult to say what the typical total motile count is. In general, 50 of men worldwide have a total motile percentage above 61. Just looking to see whether a mans sperm density and motility are both in the normal range as defined by the who criteria may be a useful screening device by referring providers to see which men should be referred to a male fertility specialist for further evaluation. This is especially important to measure if sperm motility is low, to differentiate between live non-motile sperm and dead sperm. What is considered normal at least 58 of the sperm cells should be viable. Healthy sperm motility is defined as sperm with forward progressions of at least 25 micrometers per second. If a man has poor sperm mobility, its called asthenospermia or asthenozoospermia. Asthenozoospermia is when a large percentage of sperm movement is not normal, otherwise known as abnormal sperm motility. Normal sperm should move in a progressive direction (defined as in a straight line or very larger circles). Sperm motility refers to the ability of the sperm to move efficiently. Low sperm motility is one factor that can lead to infertility.
