An ovotestis is a gonad with both testicular and ovarian aspects.[1][2] In humans, ovotestes are an anatomical abnormality associated with gonadal dysgenesis.[3] 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.

In gastropods[edit]

An ovotestis or hermaphroditic gland (in Latin language: glandula hermaphroditica),[4] is found as normal anatomical feature in the reproductive system of some gastropods including such species as the land snail Helix aspersa.[5]
