Male foetal development. Image 2 of 5. Computer artwork of the developing genitalia of a male foetus. The front of the body is at top right. The transformation takes place at twelve weeks when the tubercule (bump at centre) develops either into a penis (male) or a clitoris (female). Here the tubercule is protruding to form a penis and the scrotum is being formed from the surrounding folds. For the full sequence see images P680/0960 to P680/0964. For a full sequence showing the development of female genitalia see images P680/0955 to P680/0959.
