Answer: LH (Luteinizing Hormone).
- A FSH, which instead stimulates follicle growth
- B Estrogen, which builds up the uterine lining
- C LH (Luteinizing Hormone)
- D Progesterone, which maintains pregnancy afterward
Correct answer: C. LH (Luteinizing Hormone)
Explanation: The LH (Luteinizing Hormone) surge from the anterior pituitary triggers ovulation (release of the egg). This LH surge occurs around day 13-14 of the cycle and causes the dominant follicle to rupture and release the oocyte.
