The anterior pituitary gland in the brain releases higher-than-normal amounts of leutinizing hormone (LH) into the blood at the beginning of a woman's ovulation cycle and together with another hormone (FSH), they trigger the release of the egg from her ovaries. If she does not become pregnant then the LH levels in her blood will return to normal (as opposed to staying high after conception). Which is the most likely site in the brain for the control of these hormone levels?

The hypothalamus is responsible for regulating the release of hormones from the pituitary gland. In this case, the release of LH and FSH is stimulated by the hypothalamus, which senses changes in hormone levels and triggers the pituitary gland to release these hormones. Therefore, the most likely site for the control of these hormone levels is the hypothalamus.
