Question

If the follicle is producing estrogen, which gonadotropin (produced by the pituitary gland) is likely stimulating the production of this sex hormone? What is the relationship between FSH, the ovarian follicle, and estrogen? According to the model, what event separates the follicle phase from the luteal phase?

Answer 1

LH is likely stimulating the production of estrogen in the follicle. FSH stimulates the follicles to grow and contributes to the production of estrogen. The event that separates the follicular phase from the luteal phase is ovulation.

Step-by-step explanation:

The gonadotropin hormone LH (luteinizing hormone) is likely stimulating the production of estrogen in the follicle. LH binds to receptors on the granulosa and theca cells of the follicle, which then produce the sex hormone estradiol, a type of estrogen. FSH (follicle-stimulating hormone) stimulates the follicles to grow and also contributes to the production of estrogen by the follicles.

FSH and estrogen have a close relationship in the ovarian cycle. FSH stimulates the follicles to grow, and as the follicles grow, they produce more estrogen. The release of estrogen is stimulated by LH as well. Thus, FSH and LH work together to promote the growth of the follicles and the production of estrogen.

The event that separates the follicular phase from the luteal phase is the release of an oocyte (egg) from the dominant follicle. This is known as ovulation. After ovulation, the remaining follicles in the ovary transform into the corpus luteum, which secretes progesterone and prepares the uterus for possible implantation of a fertilized egg.
