sperm motility

Sperm motility refers to the ability of sperm cells to move efficiently through the female reproductive tract to reach and fertilize an egg. It is an important factor in fertility because, even if sperm are present in sufficient numbers, they need to be motile—that is, capable of rapid, purposeful movement—to successfully navigate to the egg. Motility is usually assessed by examining the percentage of moving sperm and how they move, with better motility indicating a higher chance of conception. Factors like health, lifestyle, and certain medical conditions can influence sperm motility.
