An ovotestis is a gonad with both testicular and ovarian aspects. In humans, ovotestes are an anatomical abnormality associated with gonadal dysgenesis. In invertebrates that are normally hermaphroditic, such as most gastropods (snails and slugs) in the clade Eupulmonata, an ovotestis is a common feature of the reproductive anatomy.
An ovotestis or hermaphroditic gland (in Latin language: glandula hermaphroditica), is found as normal anatomical feature in the reproductive system of some gastropods including such species as the land snail Helix aspersa.
