Concept:The female reproductive cycle heavily relies on negative feedback mechanisms to prevent the simultaneous maturation of too many follicles.
Solution:- As a follicle grows under the influence of FSH, it secretes increasing amounts of estrogen.
- Moderate levels of estrogen circulating in the blood exert a negative feedback effect on the anterior pituitary gland.
- This explicitly inhibits the further secretion of FSH, ensuring that only the most dominant follicle survives and no new follicles begin maturing mid-cycle.
Why other options are incorrect:Aldosterone regulates sodium/water balance. Testosterone is the primary male hormone (though inhibin and testosterone inhibit FSH in males, estrogen is the primary inhibitor during the female follicular phase). LH does not inhibit FSH.
Quality & Fidelity Assurance:
Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
