True Hermaphroditism: First Evidence of an Ovotestis in a Cetacean Species

Journal of Comparative Pathology, 2011
An immature unilateral hermaphrodite common dolphin (Delphinus delphis) was found stranded on the southwest coast of the UK. The external phenotype was that of a female, but internally there was one ovotestis, containing both ovarian follicles and testicular tubular elements, and a contralateral ovary.

The ovotestis: an underdeveloped organ of evolution

BioEssays, 2006
AbstractIn animals that have separate sexes (gonochorists), many sperm are produced to fertilise a few eggs. As the male germline undergoes more mitoses, so the accumulated mutation frequency is elevated in sperm compared with ova, and evolution is ‘male‐driven’.

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.
