About this episode

Semen parameters naturally vary between samples and are affected by abstinence interval, collection, illness, fever, laboratory methods and biological variation. This episode explains concentration, total count, motility, morphology and total motile count without reducing fertility to one score. It shows why trends and repeat testing matter more than panic over one isolated result.
