True hermaphroditism , clinically known as ovotesticular disorder of sex development ,  is a medical term for an intersex condition in which an individual is born with ovarian and testicular tissue. More commonly one or both gonads is an ovotestis containing both types of tissue. Although similar in some ways to mixed gonadal dysgenesis , the conditions can be distinguished histologically. External genitalia are often ambiguous, the degree depending mainly on the amount of testosterone produced by the testicular tissue between 8 and 16 weeks of gestation. There are extremely rare cases of fertility in "truly hermaphroditic" humans. As a result, these individuals are fertile , but not auto-fertile. There is a hypothetical scenario, though, in which it could be possible for a human to self fertilize. If a human chimera is formed from a male and female zygote fusing into a single embryo, giving an individual functional gonadal tissue of both types, such a self-fertilization is feasible. Indeed, it is known to occur in non-human species where hermaphroditic animals are common , including some mammals. According to Ovid , he fused with the nymph Salmacis resulting in one individual possessing physical traits of both sexes;  according to the earlier Diodorus Siculus , he was born with a physical body combining both sexes.
Hermaphroditism , the condition of having both male and female reproductive organs. Hermaphroditic plants —most flowering plants, or angiosperms —are called monoecious, or bisexual. Hermaphroditic animals—mostly invertebrates such as worms , bryozoans moss animals , trematodes flukes , snails , slugs , and barnacles —are usually parasitic, slow-moving, or permanently attached to another animal or plant. In humans, conditions that involve discrepancies between external genitalia and internal reproductive organs are described by the term intersex. Intersex conditions are sometimes also referred to as disorders of sexual development DSDs. Such conditions are extremely rare in humans. In true gonadal intersex or true hermaphroditism , an individual has both ovarian and testicular tissue. The ovarian and testicular tissue may be separate, or the two may be combined in what is called an ovotestis. Affected individuals have sex chromosomes showing male-female mosaicism where one individual possesses both the male XY and female XX chromosome pairs.
WHEN Cody was born intersex, her parents and doctors made a decision. She still wonders if it was the right one. A decade ago, when a baby was born with both male and female physical characteristics, doctors and parents faced a difficult choice. Now, things are changing.
