Potential defects or anomalies that can be found in sperm include:
- Head defects
- too small, too large, double-headed, balloon-shaped, with too large vacuoles...
- Midpiece defects
- too thin, too thick, too short, too long, bent, without neck...
- Tail defects
- too short, too long, duplicate tails, coiled, detached tail...
A single spermatozoon can have just one anomaly or, conversely, multiple defects.
In any case, with just an abnormality in one part, the sperm cell is considered an abnormal one.
