Correct answer: C — To reduce prolonged unopposed endometrial stimulation

The best answer is “To reduce prolonged unopposed endometrial stimulation”. Very infrequent bleeding in PCOS can expose the endometrium to prolonged unopposed oestrogen and increase hyperplasia risk. Combined hormonal contraception or intermittent progestogen can provide cycle control and endometrial protection, alongside weight and metabolic risk management.
