Pseudovaginal perineoscrotal hypospadias (PPSH) refers to a configuration of the external genitalia of an infant. In a sense, this configuration is roughly midway between normal male genitalia and normal female genitalia in structure and appearance. It is a relatively common form of genital ambiguity caused by undervirilization of genetic males due to several different intersex conditions. ==Presentation== PPSH usually consists of: * a phallus midway in size between penis and clitoris, * a chordee tethering it to the perineum, * a urethral opening usually on the perineum (the hypospadias), * and an incompletely closed urogenital opening, which resembles a small and shallow vagina. Testes are often palpable in the scrotum or inguinal canals, and the karyotype is XY. In most cases there are no internal female structures such as a uterus or other Müllerian duct derivatives. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「pseudovaginal perineoscrotal hypospadias」の詳細全文を読む スポンサード リンク
