What does the clinician need from an andrology laboratory? The andrology laboratory is vital for the accurate diagnosis and treatment of male factor infertility, which is contributory in 50% of infertile couples. While there are some diagnostic tests of limited clinical utility, many tests can be useful in specific clinical settings. In this chapter, we will review the basic interpretation of the semen analysis, testing for sperm vitality and motion, inflammation, semen antioxidant capacity, sperm DNA damage, antisperm antibodies, post ejaculate urine analysis as well as other functional testing. Several clinical vignettes are presented for real-life examples of interpretation of the role of the andrology laboratory in clinical infertility.
