Rationale: There are two arteries in an umbilical cord. The umbilical cord contains two arteries and one vein. Artery carries blood away from the fetus, while the vein returns blood to the fetus.

2. What laboratory values are not typically elevated in a patient with PCOS?

A. LH
B. Androgens
C. Estrogens
D. Prolactin

Correct answer: D

Rationale: The correct answer is D: Prolactin. Prolactin levels are not typically elevated in patients with PCOS. Elevated LH and androgens are commonly seen in PCOS patients. While estrogen levels can vary in PCOS, they are not consistently low or high in all cases.

3. Which hormone is released from the testes?

A. Progesterone
