Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the role of LH.
Luteinizing hormone (LH) is a gonadotropin hormone secreted by the anterior pituitary gland. It plays a crucial role in regulating the menstrual cycle.
Step 2: LH surge during menstrual cycle.
Midway through the menstrual cycle, a sudden and sharp increase in LH level occurs, known as the LH surge.
Step 3: Effect of LH surge.
This LH surge triggers the rupture of the mature Graafian follicle in the ovary, releasing the ovum.
Step 4: Conclusion.
Therefore, a sudden rise in LH level directly stimulates ovulation.
