Hyena female genitalia:
These pseudo-penises, or pseudophalluses, are paired with "testicles"—actually fused labia filled with fatty tissue
The genitalia of the female closely resembles that of the male; the clitoris is shaped and positioned like a penis, a pseudo-penis, and is capable of erection. The female also possesses no external vagina (vaginal opening), as the labia are fused to form a pseudo-scrotum. The pseudo-penis is traversed to its tip by a central urogenital canal, through which the female urinates, copulates and gives birth. The pseudo-penis can be distinguished from the males' genitalia by its somewhat shorter length, greater thickness, and more rounded glans. In both males and females, the base of the glans is covered with penile spines. The formation of the pseudo-penis appears largely androgen independent, as the pseudo-penis appears in the female fetus before differentiation of the fetal ovary and adrenal gland. When flaccid, the pseudo-penis is retracted into the abdomen, and only the prepuce is visible. After giving birth, the pseudo-penis is stretched, and loses many of its original aspects; it becomes a slack-walled and reduced prepuce with an enlarged orifice with split lips.
