What is the relationship between luteinising hormone and ovulation?

Luteinising hormone (LH) plays a crucial role in the menstrual cycle and is directly involved in the process of ovulation. This hormone is produced by the pituitary gland and triggers the ovulatory phase of the cycle. Just before ovulation, there is a surge in LH levels, which signals the ovary to release a mature egg.

This surge is essential; it initiates several biochemical changes that lead to the ovulation process. Once LH levels peak, it promotes the final maturation of the follicle and the subsequent release of the ovum. In summary, LH stimulates ovulation by facilitating the release of the egg from the ovarian follicle, making it a key player in female reproductive physiology.
