Development Animation - Genital Female External
Female External Genital Development
This looped animation shows the development of external female genitalia from the indifferent external structure, covering the approximate period of week 9 to 12. (Anterior to top, Posterior to bottom)
Note the original cloacal membrane becomes separated into the urogenital membrane and anal membrane. The urogenital folds beneath the genital tubercle remain separate (unfused), forming the inner labia minora and second outer skin folds form the larger labia majora either side of the developing vestibule of the vagina. Note at the top of the animation, the changing relative size of the genital tubercle as it forms the glans of the clitoris.
