Select the incorrect statement.

A \(LH\) and \(FSH\) decrease gradually during the follicular phase.
B \(LH\) triggers secretion of androgens from the Leydig cells.
C \(FSH\) stimulates the sertoli cells which help in spermiogenesis.
D \(LH\) triggers ovulation in ovary.

Answer & Solution

Correct Answer

(A) \(LH\) and \(FSH\) decrease gradually during the follicular phase.

Step-by-step Solution

Detailed explanation

(a) : During follicular phase \(FSH\) secretion increases. Follicular phase (proliferative phase) usually includes cycle days \(6-13\) or \(14\) in a \(28\) days cycle. The follicle stimulating hormone \((FSH)\) secreted by the anterior lobe of the pituitary gland stimulates the ovarian follicle to secrete estrogens.

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.
