Which of the following events is not associated with ovulation in human female?

A Release of secondary oocyte
B \(LH\) surge
C Decrease in estradiol
D Full development of Graafian follicle

Verified Solution

Answer & Solution

Correct Answer

(C) Decrease in estradiol

Step-by-step Solution

Detailed explanation

(c) : In human females, ovulation is the release of secondary oocyte from the ovary at about \(14^{th}\) day of the menstrual cycle. Both \(LH\) and \(FSH\) attain a peak level during this period. Rapid secretion of \(LH\) induces rupturing of fully developed Graafian follicle and thereby release of ovum. \(LH\) surge is actually responsible for ovulation.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
