Answer to Question 1

Ans:
A, C, D, E, F

Feedback:

In women, the pituitary release of FSH, LH, and prolactin at puberty stimulates the ovary to produce and release estrogen. This estrogen stimulates the growth and proliferation of the ductile system. With the onset of ovulatory cycles, progesterone release stimulates the growth and development of ductile and alveolar secretory epithelium.

Answer to Question 2

Ans:
B

Feedback:

Vascular disease affects male potency because it may impair blood flow to the pudendal arteries or their tributaries, resulting in loss of blood volume with subsequent poor distention of the vascular spaces of erectile tissue. Premature ejaculation is not caused by a vascular problem. Penile engorgement is expected as part of an erection. Vascular clots may relate to a trauma or surgery to the penis.
