Which of the following hormone helps in ovulation?

Ovulation is the process of release of an ovum from the ovary. It occurs in the middle of the menstrual cycle, which is associated with the pituitary hormones' level. In the middle of the menstrual cycle, the secretion of LH (luteinizing hormone) becomes high; it is called the LH surge, which induces the rupturing of the mature follicle and causes the release of an ovum (ovulation). So, the correct answer is 'Leutenizing hormone'.
