     A. Follicle-stimulating hormone

     B. Progesterone

     C. Estrogen

     D. Luteinizing hormone

    

    

Correct Answer: A. Follicle-stimulating hormone

---

The hormone that stimulates the maturation of the Graafian follicle is the Follicle Stimulating Hormone which is released by the anterior pituitary gland.

Option B: Progesterone prepares the endometrium for the potential of pregnancy after ovulation. It triggers the lining to thicken to accept a fertilized egg. It also prohibits the muscle contractions in the uterus that would cause the body to reject an egg.

Option C: Estrogen helps control the menstrual cycle and is important for childbearing. Estrogen also has other functions: it keeps cholesterol in control and protects bone health for both women and men.

Option D: Luteinizing hormone is crucial in regulating the function of the testes in men and ovaries in women. In men, luteinizing hormone stimulates Leydig cells in the testes to produce testosterone, which acts locally to support sperm production.
