Question

Quizplus · Accepted Answer

Ovulation is triggered by a surge in the secretion of luteinizing hormone (LH) from the anterior pituitary gland. This surge is stimulated by an increase in the production of gonadotropin-releasing hormone (GnRH) by the hypothalamus, which is in turn stimulated by rising levels of estradiol. Testosterone and inhibin also play roles in regulating the reproductive system but are not directly involved in triggering ovulation.
