Penis
,Wikify foreskin.
Only after that do the different external features emerge. Between the 11th and 17th week the genital tubercle becomes the clitoris in females, and the glans in males.
In girls, the genital fold remains open, in boys it grows together. It transforms into the inner labia and the clitoral hood in girls, and into the [[foreskin ]] in boys. The labioscrotal swelling becomes the outer labia and scrotum respectively.
The growing together of the folds results in the seam that runs from the underside of the scrotum and the penile shaft up to the tip of the foreskin. The penis now consists of the shaft containing the erectile tissue, with the glans at the top. The shaft is surrounded by the shaft skin which, however, is not knitted to it. This mobility, combined with the stretching capabilities of the skin, allows for the growth in dimension of the penis during an erection. During an erection the erectile tissue fills with blood, giving the penis its stiffness and enlarged size.
