Teratozoospermia can be detected using a semen analysis. The specialist counts the number of sperms that have an abnormal shape. Depending on the criteria followed, the chances for a man to have teratozoospermia will vary. The following are the different criteria used to determine if a man has teratozoospermia or not:
- WHO's criteria
- If the percent of normal sperms is lower than 4%.
- Kruger's strict criteria
- If the percent of normal sperms is below 15%.
