Semen analysis is the most essential part of diagnosing male infertility. It is a laboratory test of freshly ejaculated semen, of which the number, shape and movement are measured under a microscope. These tests should be done at specialised laboratories that use methods approved by the World Health Organisation.
Table 2 shows the parameters of normal semen. Based on results of the semen analysis, physical examination and other tests can help to determine the different types of male infertility.
