  » Infertility  »  Semen analysis

This is a very important test and should be done early in the evaluation process. If a severe sperm defect is discovered, the testing on the female partner might be modified, and therapy can be immediately directed to the problem.
About 25% of all infertility is caused by a sperm defect and 40-50% of infertility cases have a sperm defect as the main cause, or a contributing cause.
