this is the test used to see if the sperm is able to successfully penentrate the egg. hamster zona-free ovum test (HZFO test)is called so because they use hamster eggs instead of a human ova. don't worry, there is no fertilization!

hahahaha... human sperm can only fertilize human egg... One of the safeguards of nature.

BTW, why are some sperm unable to penetrate an egg?

I think this is one of those "defective" sperms. Some men because of factors seem to produce sperm that are misshapen or have low motility. Others have low sperm count.

This test measures the ability of the sperm to penentrate the barriers surrounding the ovary in order to successfully fertilize the egg. The more sperm that are able to penentrate, the better it is for the guy's swimmers.
