Intersex is a group of conditions where there is a discrepancy between the external genitals and the internal genitals the testes and ovaries. The older term for this condition is hermaphroditism. Although the older terms are still included in this article for reference, they have been replaced by most experts, patients and families.
Hermaphrodism In Humans
For example, the great majority of tunicates , pulmonate snails, opisthobranch snails , earthworms , and slugs are hermaphrodites. Hermaphroditism is also found in some fish species and to a lesser degree in other vertebrates. Most plants are also hermaphrodites. Historically, the term hermaphrodite has also been used to describe ambiguous genitalia and gonadal mosaicism in individuals of gonochoristic species, especially human beings. The word intersex has come into usage for humans, since the word hermaphrodite is considered to be misleading and stigmatizing,   as well as "scientifically specious and clinically problematic.
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. Most often, but not always, the chromosome complement is 46,XX, and in every such individual there also exists evidence of Y chromosomal material on one of the autosomes any of the 22 pairs of chromosomes other than the sex chromosomes.
A 3-year-old child presented with left sided undescended testis and penoscrotal hypospadias. Chordee correction was performed 18 months back, elsewhere. At laparotomy Mullerian structures were present on left side. On right side testis was normally descended into the scrotum. True hermaphrodite or ovo-testicular disorder of sexual differentiation OVO-DSD is one of the rarest variety of all inter sex anomalies. There have been reports of 46 XY karyotype [ 1 ]. In this condition gonads are asymmetrical having both ovarian and testicular differentiation on either sides separately or combined as ovotestis.
