Question #45552
The Question
A couple relying on lactational amenorrhea for contraception experiences an unintended pregnancy at 5 months postpartum. They opt for a Medical Termination of Pregnancy (MTP) at 10 weeks of gestation. Which of the following statements regarding the physiological mechanism of this natural contraceptive method and the clinical guidelines for MTP is INCORRECT?
Options
- A.
The method failed because the resumption of pulsatile GnRH release from the hypothalamus, leading to an LH surge, can occur before the first postpartum menses.
- B.
The primary endocrine basis for lactational amenorrhea is the high titer of oxytocin, which exerts strong negative feedback on the anterior pituitary to halt FSH and LH secretion.
- C.
According to the MTP Act, termination of pregnancy at 10 weeks is considered safe as it falls within the first trimester, requiring the opinion of one registered medical practitioner.
- D.
Even with intense and exclusive breastfeeding, the maximum recognized period of high efficacy for lactational amenorrhea is only up to six months following parturition.

Why This Question Is Tricky
Common Mistakes
Functional Overlap Trap: Students frequently confuse the roles of the two primary lactation hormones.
They must distinguish between Prolactin (milk synthesis and GnRH suppression via negative feedback) and Oxytocin (milk let-down reflex with no role in amenorrhea).
Additionally, it tests the integration of Reproductive Health (MTP laws, contraceptive failure) with Human Reproduction (H-P-A axis endocrinology).
