surmounted by a glans, and cleft or furrowed along its under surface. 

 The borders of the furrows diverge posteriorly, running at the sides of 

 the genito- urinary orifice internally to the cutaneous folds just mentioned 

 (see Figs. 465, 466, 467). In the female, this body becoming retracted, 

 forms the clitoris, and the margins of the furrow on its under surface are 

 converted into the nymphae, or labia minora, the labia majora pudendae 

 being constituted by the great cutaneous folds. In the male foetus, the 

 margins of the furrow at the under surface of the penis unite at about the 

 fourteenth week, and form that part of the urethra which is included in 

 the penis. The large cutaneous folds form the scrotum, and later (in the 

 eighth month of development), receive the testicles, which descend into 

 them from the abdominal cavity. Sometimes the urethra is not closed, 

 and the deformity called hypospadias then results. The appearance of 

 hermaphroditism may, in these cases, be increased by the retention of the 

 testes within the abdomen.
