What Is
Oligoasthenoteratozoospermia?
Oligoasthenoteratozoospermia (OAT) occurs when a man has:
- A low sperm count (oligozoospermia)
- Poor sperm motility or movement (asthenozoospermia)
- Abnormal sperm shape or morphology (teratozoospermia)
With this condition, all variables on a semen analysis are subnormal. OAT is a common cause of male subfertility.
