Female foetal development. Image 4 of 5. Computer artwork of the developing genitalia of a female 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 it is receding to form the clitoris and the genital folds are deepening to form the labia. For the full sequence see images P680/0955 to P680/0959. For a full sequence showing the development of male genitalia see images P680/0960 to P680/0964.
