Types of teratozoospermia

Types of teratozoospermia

Teratozoospermia is defined as having abnormal sperm morphology. It is a common cause of male infertility and can be classified into three grades depending on the severity:

Mild teratozoospermia
Between 10% and 14% of the sperm have a normal morphology.
Moderate teratozoospermia
Only 5-10% of the sperm have an abnormal shape.
Severe teratozoospermia
Less than 5% of the sperm have a normal morphology.

It should be noted that this definition has been created using the Kruger's strict criteria, according to which a man has teratozoospermia if over 85% of the sperms present in his ejaculate have an abnormal morphology.
