What’s inside: You’ll read about why the WHO’s “normal” sperm thresholds are too low and create a false sense of security, which parameters and cutoffs really matter, and how (and when) to get tested.
Let’s say a man provides a sample at a fertility clinic: 50 million sperm per milliliter, 40% motility, 5% normal morphology. Most doctors would declare this “normal.” Is that the end of the story? Not really, here’s what often goes unsaid: “normal” by WHO standards is not the same as “optimal for making babies.”
