Male External Genital Development

This looped animation shows the development of external male 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 (identical to female). The urogenital folds beneath the genital tubercle begin to fuse in the midline. The skin folds either side for the scrotum, which too has a midline fusion, the raphe. The scrotal sac is initially empty and is an attachment site for the gubernaculum, descent of the testes begins generally during week 26 and may take several days.

Failure of this fusion event leads to hypospadias a common male genital abnormality.
