These tests are used to check how well the sperm survive following ejaculation, as well as how they penetrate an egg. Sperm function studies can also assess if there is a problem attaching to the egg. These tests are not usually performed, as they do not change treatment.
Basic Workup for Male Infertility
Approximately 90% of male infertility cases are related to poor sperm quality, low sperm counts, or both. Other causes of male infertility are related to hormone imbalances, genetic defects, and anatomical problems. Infertility testing may not be covered by your insurance, so be sure to ask the fertility specialist which tests are right for you.
