Male external genitalia do not develop
A. In the presence of an X chromosome.
B. Without androgen secretion by the fetal testes
C. Without prior regression of the Mullerian ducts
D. If Wolffian ducts develop.
E. In the absence of estrogen in the fetus.

Androgen secretion by the fetal testis is important for male external genitalia development or sexual differentiation. Testosterone especially has a major role in the development of the testes, prostate and other cells and tissue responsible for the development of the reproductive organs and external genitalia.

Androgen mainly testosterone is metabolized and DHT is required for androgen-induced development of the external genitalia.

Thus, the correct answer is option B. Without androgen secretion by the fetal testes.

Male external genitalia do not develop A. In the presence of an X chromosome. B. Without androgen secretion by the fetal testes C. Without prior regression of the Mullerian ducts D. If Wolffian ducts develop. E. In the absence of estrogen in the fetus.
