True hermaphroditism , sometimes referred to as ovotesticular disorder ,    is an intersex condition in which an individual is born with ovarian and testicular tissue. 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. Estimated frequency of ovotestes is one in 83, births 0. There are extremely rare cases of fertility in "truly hermaphroditic" humans. As a result, these individuals are fertile , but not auto-fertile.
Hida Viloria is a writer who holds a degree in Gender and Sexuality from U. She is also an activist for intersex people -- formerly known as hermaphrodites Her memoir "Mighty Hermaphrodite" will be published next spring. Hida Viloria says she looks forward to a day when intersex conditions like hers are widely accepted. Intersex people formerly known as hermaphrodites are those born with bodies that are difficult to classify as either "male" or "female. Since results of Semenya's tests were apparently leaked, it seems that her body doesn't conform to the definition of "female" as one who has ovaries.
A hermaphrodite is an organism having both male and female reproductive organs. Hermaphroditism most commonly occurs in invertebrates , although it is also found in some fish , and to a lesser degree in other vertebrates. Historically, the term hermaphrodite has also been used to describe ambiguous genitalia and gonadal mosaicism in individuals of gonochoristic species, especially human beings.
