Male infertility is commonly due to abnormalities in the sperm. A semen analysis test examines a number of important parameters in a man’s ejaculate. The volume, density (sperm count), motility and morphology (shape) of the sperm is assessed under the microscope. If a sample is not completely normal you can discuss it with a fertility specialist. There are a number of nutritional and lifestyle changes that can improve semen parameters when a sample isn’t normal. See our article on “Optimising Sperm for IVF”.
