Are teratozoospermia and necrozoospermia the same?

By Marta Barranquero Gómez B.Sc., M.Sc. (embryologist).
Last Update: 09/30/2022

The answer is no. Teratozoospermia and necrozoospermia are seminal alterations, but each refers to a spermatic parameter.

On the one hand, teratozoospermia is an alteration in sperm morphology. In contrast, necrozoospermia refers to problems in the vitality of sperm, that is, when there are a lot of dead sperm in the ejaculate.
