There are several methods for testing sperm fertilization function:
(1) Semen analysis: Through semen analysis, we can know how many moving sperm there are in the semen, the strength of the motility, and whether the sperm morphology is normal. All these indicators have an important impact on the ability of the sperm to penetrate the egg and the fertilization function. is a very important factor.
(2) Acrosome reaction: The acrosome reaction test is to understand the function of sperm penetrating the egg A special test that is an important indicator of male fertility. By measuring the sperm acrosome, we can learn whether the sperm has the function of releasing acrosome enzymes, as well as the sperm\’s ability to penetrate the egg and fertilize. In semen analysis, sperm with normal morphology also have abnormal acrosome reactions. This kind of Sperm has no function of penetrating the egg and fertilizing it.
