Answer to Question 1

These drugs inhibit the action of the phosphodiesterase enzyme that normally breaks down cGMP that is responsible for smooth muscle relaxation in the penile arteries and the trabeculae within the corpora cavernosa. By inhibiting the phosphodiesterase enzyme, the vasodilator action of cGMP is sustained, resulting in an increased blood flow to the penis (sildenafil (Viagra), vardenafil, tadenafil).

Answer to Question 2

HCG, AFP
