Actually, ovulation occurs by a surge in the secretion of luteinizing hormone (LH). LH is released by the pituitary gland in the brain and stimulates the release of the egg from the ovary during ovulation. Estrogen hormone plays a role in the menstrual cycle by promoting the growth of the uterine lining, but it's the surge in LH that triggers the release of the egg. So, the correct answer is luteinizing hormone.
