Question

What is the fate of corpus luteum in case of unfertilized egg?

• A. Rapid proliferation
• B. Degeneration
• C. Secretion of progesterone
• D. Onset of next menstrual cycle

Answer 1

Answer:

B. Degeneration

Corpus luteum releases progesterone to support endometrium required for homing the embryo. But if the egg is not fertilized, the endometrium is useless and should be released off to save energy. Thus corpus luteum is degraded.
