How is oligoasthenoteratozoospermia diagnosed?

Oligoasthenoteratozoospermia is a combination of abnormalities in sperm concentration, motility, and morphology.

The semen analysis is the basic test for diagnosing oligoasthenoteratozoospermia. By evaluating the microscopic parameters of sperm concentration, motility, and morphology, the specialist can determine whether the man has this semen abnormality.

Specifically, and based on the 2010 criteria established by the World Health Organization (WHO), a man is considered to have oligoastenoteratozoospermia when his semen contains fewer than 15 million sperm per milliliter of ejaculate, has a motility rate of less than 40%, and a percentage of normal sperm of less than 4%.
