LH (luteinizing hormone) surge is necessary for ovulation to occur. By blocking the LH surge, ovulation will be prevented, making option B the correct answer. Option A is incorrect because the LH surge triggers a peak in progesterone, not estrogen. Option C is also incorrect because the LH surge causes the corpus luteum to produce progesterone, but does not directly cause a peak in progesterone.

Option E is incorrect because the degeneration of the corpus luteum is a result of the absence of LH, not its presence.
