Are Faster sperm better?

When it comes to sperm meeting eggs in sexual reproduction, conventional wisdom holds that the fastest swimming sperm are most likely to succeed in their quest to fertilize eggs.

Does the speed of sperm matter?

The speed at which sperm swim is a major predictor of fertility and is extremely variable in human populations.

Does the fastest sperm actually win?

There is ample evidence to show that as millions of human sperm cells swim towards a waiting ovum or egg, only one gets to fertilize it. Now, a new study shows that even though the fastest and most capable sperms reach the ovum first, it is the egg that has the final say on which sperm fertilizes it.

Why are some sperm faster than others?

One explanation has to do with the chromosomes in sperm. The Y chromosome, which makes boys, contains less DNA than the X chromosome for girls. That means sperm that bear a Y chromosome swim faster in viscous liquids.

What should be the speed of sperm?

However, a study from 2020 highlighted that it isn't the sperm that rushes to claim its first position, it's in fact the egg that chooses which one gets to win.

Does sperm speed affect pregnancy?

How does sperm motility affect fertility? Sperm motility is the ability of sperm to move efficiently. This is important in fertility because sperm need to move through the woman's reproductive tract to reach and fertilize her egg. Poor sperm motility can be a cause of male factor infertility.
