Necrozoospermia is the medical term to describe the condition where a low percentage of live sperm and a high percentage of immotile sperm are found in a fresh semen sample. This means that a high percentage of the sperm cells are dead.

According to the World Health Organization, the percentage of live sperm should be greater than 58% and anything lower qualifies as necrozoospermia.

Necrozoospermia is also known as necrospermia.
