Answer to Question 1

Ans:
B

Feedback:

Because the foreskin is often used in surgical repair of hypospadias, circumcision is normally contraindicated. Chromosomal studies are frequently warranted, and surgery is the standard treatment for the repair of the urethra. Testosterone supplementation is often necessary.

Answer to Question 2

Ans:
C

Feedback:

AMH suppresses the development of female genital structures and is a normal aspect of normal sex differentiation. Testosterone is a precursor to DHT rather than vice versa, and testes develop under the influence of the Y chromosome. The Wolffian ducts are a component of male sex differentiation.
