TRUE HERMAPHRODITISM; ENDOCRINE STUDIES IN A CASE OF OVOTESTIS

Obstetrical & Gynecological Survey, 1947
THE occurrence of both male and female gonads in one person is of sufficient rarity to invite thorough study of such a case. Pseudohermaphroditism is not uncommon, but the occurrence in one person of one ovary and testis, or an ovotestis, proved histologically, has been reported only 40 times in the literature (1, 2, 4, 5, 6, 7).

Why the Ovotestis ofHelix aspersais Innervated

Acta Biologica Hungarica, 2004
Although Schmalz described the innervation of the ovotestis in pulmonate snails as early as 1914, no functions have been attributed to it. In H. aspersa, the intestinal nerve branches profusely within the ovotestis and terminates in the walls of the acini and in the sheath surrounding the early portion of the hermaphroditic duct.
