Answer- The elevated estrogen level acts as a positive feedback mechanism by stimulating the pituitary to release LH hormone.
Explanation- The estrogen level reaches its peak during the mid cycle. The increased level of estrogen produces a positive feedback and stimulates the pituitary to secrete LH hormone. Rapid LH secretion leads to LH surge and the release of ovum(ovulation) takes place under its effect.
