Question

What does the LH surge cause to occur during the ovulatory phase?

Options

• Corpus luteum formation

• Endometrial proliferation

• Prostaglandin release

• The Graafian follicle to rupture

Answer 1

The LH surge causes the Graafian follicle to rupture during the ovulatory phase. This rupture is essential for the release of the secondary oocyte (not a mature ovum) from the ovary, an event known as ovulation.
