Question

What determines the size of the Graafian Follicle?

Answer 1

Graafian follicle:

1. It is the matured follicle containing the ovum.
2. The follicle ruptures and releases the ovum during the ovulatory phase.
3. After ovulation, the Graafian follicle transforms into the corpus luteum, which secretes progesterone and is required for the maintenance of pregnancy.

Factors that determine the size of the Graafian follicle:

1. Toward the midpoint of the menstrual cycle, the mature Graafian follicle, containing the egg that has been arrested in the prophase of the first meiotic division, has moved to the surface of the ovary.
2. From the influence of follicle-stimulating hormone (FSH) and luteinizing hormone (LH), the follicle expands dramatically.
3. FSH stimulates the development of the Graafian follicle, a small vesicle containing an egg, in the ovary of the female mammal.
4. In males, it promotes the development of the tubules of the testes and the differentiation of sperm.
