Keeping yourself generally fit and healthy will ensure that you optimise your reproductive health. Many unrelated conditions such as diabetes result in impairment of sperm quality. Indeed, one of the first signs of a cardiac condition is poor semen parameters. A well man screen can look at biochemical markers in the blood that can indicate any potential problems.
Toxic metals in our environment e.g. lead, cadmium, affect sperm quality and prevent fertilization. A screen for environmental toxins in the blood looks at levels of harmful metals as well as those that are protective. It is useful for men who have poor sperm quality, poor IVF fertilisation rates, unexplained infertility and varicocoele. Men exposed to cigarette smoke, increased alcohol, occupational or environmental toxins may also be exposed to harmful levels of heavy metals
