BALASOURY · Accepted Answer

## CORE INFORMATION
✓ **Answer**: D
## CONCEPT FRAMEWORK
	**Primary Concept**: Hormonal control of the menstrual cycle.
	**Related Topics**: Ovarian cycle, uterine cycle, feedback mechanisms of hormones
	**Prerequisites**: Basic understanding of the menstrual cycle and the roles of FSH, LH, estrogen and progesterone.
## SOLUTION PATHWAY
**Given Information**:
	The question asks how to defer menstruation.
	Menstruation occurs due to the drop in estrogen and progesterone levels.
**Method & Steps**:
	1. Identify the hormones responsible for maintaining the uterine lining and preventing menstruation.
		Reasoning: Estrogen and progesterone maintain the uterine lining.
		Formula/Rule: - 
	2. Determine which option provides these hormones in combination.
		Working: Option D provides estrogen and progesterone.
		Key Point: A drop in estrogen and progesterone leads to menstruation.
	3. Conclude that administering these hormones can defer menstruation.
		Result: Option D is the correct answer.
		Verification: The combination of estrogen and progesterone mimics the luteal phase of the menstrual cycle, preventing the shedding of the uterine lining.
 ## OPTION ANALYSIS
[A] :x: FSH primarily stimulates follicle development and estrogen production. It does not directly maintain the uterine lining to prevent menstruation.
[B] :x: LH primarily triggers ovulation and the formation of the corpus luteum, which then secretes progesterone. LH alone will not prevent menstruation.
[C] :x: While both FSH and LH play roles in the menstrual cycle, their combined administration would not prevent menstruation as they do not directly maintain the uterine lining for a sustained period.
[D] ✓: A combination of estrogen and progesterone is required to maintain the uterine lining and prevent menstruation. This mimics the hormonal profile of the luteal phase and prevents the shedding of the endometrium.
 ## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing the roles of FSH and LH: Remember FSH is primarily for follicle development, and LH triggers ovulation.
		2. Thinking one hormone is enough to maintain the uterine lining: Both estrogen and progesterone are needed.
	**Quick Tips**:
		1. Think of the luteal phase: The luteal phase is characterized by high levels of both estrogen and progesterone, which maintains the uterine lining.
		2. Remember the drop in hormones: A drop in both hormones triggers menstruation.
