The Sexual Health Inventory for Men is an abbreviated version of the International Index of Erectile Function. It asks about the last six months and produces a score between 5 and 25, which maps onto five severity bands.

ScoreInterpretation
22–25No erectile dysfunction
17–21Mild
12–16Mild to moderate
8–11Moderate
5–7Severe

A score is a description, not a diagnosis. It says nothing about the cause — and with erectile dysfunction, the cause is the part that matters most.
