Penis
,→Anatomy and development of the male genital organ
Up to the ninth week of pregnancy, both male and female genital organs develop identically. Genital tubercle, labioscrotal swelling, genital fold and urogenital membrane have developed.
Only after that do the different external features emergein the [[fetus]]. 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.
