The SRY gene , usually located on the Y chromosome and encoding the testis determining factor , determines the direction of this differentiation. The absence of it allows the gonads to continue to develop into ovaries. Thereafter, the development of the internal, and external reproductive organs is determined by hormones produced by certain fetal gonads ovaries or testes and the cells' response to them. The initial appearance of the fetal genitalia looks basically feminine: If the fetus has testes, and if the testes produce testosterone, and if the cells of the genitals respond to the testosterone, the outer urogenital folds swell and fuse in the midline to produce the scrotum; the protuberance grows larger and straighter to form the penis; the inner urogenital swellings grow, wrap around the penis, and fuse in the midline to form the penile urethra.
