Question

Quizplus · Accepted Answer

The rise in follicle-stimulating hormone (FSH) at the beginning of the ovarian cycle stimulates the growth and maturation of ovarian follicles. FSH acts on the granulosa cells of the developing follicle, promoting the production of estrogen. This estrogen production initiates a positive feedback loop that further stimulates FSH secretion, leading to the selection of a dominant follicle that will ovulate. Therefore, the correct option is A) follicle maturation.
