General Information
Term spicule insertion ID (Ontology) GO:0034609 (Gene Ontology)
Definition Insertion of the male copulatory spicules into the hermaphrodite. Spicule insertion behavior initiates when the male cloaca contacts the vulva. During most mating encounters, the spicule tips will prod the vulva continuously until they partially penetrate, which then causes the protractors to contract completely so that the spicules extend through the vulva.[ PubMed:18050467 ]
