Phallus

Stages in the development of the external sexual organs in the male and female.

Gray's subject #252 1213

In embryology, the phallus refers to the clitoris of a female, particularly during fetal development of the urinary and reproductive organs, before sexual differentiation is evident. This is also the case for the immature male analog, the immature glans penis.
