Question

The given graph represents the changes in thickening of uterine wall in two women X and Y over a period of one month. What should be the correct conclusion regarding this?

• A. Woman X has conceived
• B. Woman Y is undergoing menopause
• C. Both women X and Y will undergo menarche in the next month
• D. Both A and B

Answer 1

The correct option is A Woman X has conceived

If the egg does not get fertilized after ovulation, around 14${}^{th}$ day, then the uterine lining is shed in the form of menses during the menstrual cycle which occurs every 28 days. If the egg is fertilized, the uterine lining grows in order to support the developing embryo.
In the diagram, the uterine wall thickness of woman Y starts decreasing after 14${}^{th}$ day, meaning the egg has not been fertilized.
While, the wall thickness of woman X started increasing, meaning egg has been fertilized and she has conceived.
Thus, the correct answer is option A.
