How well do sperm shape scores predict male fertility?

According to the World Health Organization’s criteria for judging sperm shape, only 30% of sperm need to be normal for a semen analysis to be considered normal. Most fertility centers use a stricter set of criteria called the Kruger criteria, by which only 15% of sperm need to be normal. Despite this 15% cutoff level, many men with lower morphology scores may still be fertile, albeit, subfertile.
