Which statement regarding primary dysmenorrhea is most accurate?
Correct Answer: D
Rationale: The correct answer is D because primary dysmenorrhea is often caused by excessive endometrial prostaglandin production, leading to increased uterine contractions and pain. This is supported by research and clinical evidence.
A: Incorrect. Not all women experience primary dysmenorrhea; it varies in prevalence.
B: Incorrect. Oral contraceptives can help manage dysmenorrhea by reducing prostaglandin production.
C: Incorrect. Primary dysmenorrhea is more common in nulliparous women, not multiparous women.
In summary, D is correct due to the established link between excessive prostaglandin and primary dysmenorrhea, while the other choices are inaccurate based on current knowledge and research.
