A<unk>  is a body of tissue present in the development of the urinary and reproductive organs. It forms in the ventral, caudal region of mammalian embryos of both sexes, and eventually develops into a phallus. In the human fetus the<unk>  develops around week 4 of gestation, and by week 9 becomes recognizably either a clitoris or penis.
Even after the phallus is developed, the term<unk>  remains, but only as the terminal end of it, which develops into either the glans penis or the glans clitoridis.
The<unk>  is sensitive to dihydrotestosterone and rich in 5-alpha-reductase, so that the amount of fetal testosterone present after the second month is a major determinant of phallus size at birth.
