Step 1: Recall the hormonal profile of PCOD. There is increased pulsatile GnRH leading to a raised LH and a reversed LH/FSH ratio (classically about 2:1 or more).
Step 2: Androgens are increased; adrenal androgen DHEAS is mildly to moderately elevated in a proportion of patients, and ovarian androgens (testosterone) are raised, producing hyperandrogenism.
Step 3: Consider prolactin. A mild elevation in prolactin can occasionally be seen, but a MARKEDLY high prolactin is not a feature of PCOD. A markedly raised prolactin points to a prolactinoma or other cause of hyperprolactinaemia, which is a separate differential. Therefore markedly high prolactin is the false statement.
Step 4: Hence the exception is markedly high prolactin.
Answer: Option C, Markedly high prolactin.
