 In approximately 50% of infertile couples the male contributes at least partially to the cause of the problem. Observing ejaculated semen with the naked eye will usually not contribute to making a decision whether a man is fertile or sterile. It is therefore only logical to perform a semen analysis as one of the first tests when an infertile couple is examined.
- COUNT: Anything below 10million sperm per mil or above 200million sperm per mil is considered abnormal
- MOTILITY: If less than 30% of the sperm is not moving with direction i.e. not in a straight line there is a motility problem
 MORPHOLOGY: If less than 14% of the sperm have an abnormal shape there is a problem as only the classic 'acorn' shaped sperm can penetrate an egg naturally
- INFECTION: White cells seen under the microscope are when the sperm is being tested indicates and infection. The type of infection is isolated by doing a sperm culture for micro-organisms
- POSITIVE MAR: Is a screening test done to assess what extend the sperm tends to clump together, preventing it being able to swim freely.
- ANTIBODIES: These are confirmed by doing a blood test particularly if the mar is positive. Antibodies are present if there has been trauma to the testicles through an accident or operation
- VOLUME: If the volume is less than 2mls some of the components in the ejaculate might be missing.
