The endometrial thickness is greatest during the:
- A. Secretory phase
- B. Menstrual phase
- C. Proliferative phase
- D. Late follicular phase
Correct Answer: A
Rationale: The correct answer is A: Secretory phase. During the secretory phase of the menstrual cycle, the endometrial thickness is greatest due to increased progesterone levels, leading to thickening of the endometrium in preparation for potential implantation of a fertilized egg. This phase occurs after ovulation and is characterized by glandular secretions and increased vascularity to support a potential pregnancy.
Summary:
- Menstrual phase (B) is incorrect as it is characterized by shedding of the endometrial lining.
- Proliferative phase (C) is incorrect as it involves endometrial thickening but not to the extent seen in the secretory phase.
- Late follicular phase (D) is incorrect as it precedes ovulation and is primarily characterized by follicular development rather than significant endometrial thickening.
If a woman’s menstrual cycle began on June 2, on which date should ovulation mostly likely have occurred?
- A. Jun-10
- B. Jun-16
- C. Jun-29
- D. Jul-05
Correct Answer: B
Rationale: The menstrual cycle is typically 28 days, with ovulation occurring around day 14. In this case, if the cycle started on June 2, ovulation would likely occur around June 16, which is 14 days after the start. Choice A (Jun-10) is too early for ovulation. Choice C (Jun-29) and D (Jul-05) are too late based on the standard 28-day cycle. Therefore, choice B (Jun-16) is the correct answer based on the expected timing of ovulation in a typical menstrual cycle.
