Question

Quizplus · Accepted Answer

The corpus luteum develops from the ruptured follicle after ovulation. The follicle is transformed into the corpus luteum that secretes estrogen and progesterone.

Note: Option A) is incorrect because the polar body is just a byproduct of meiosis and does not develop into anything. Option B) is incorrect because the fertilized ovum develops into the embryo, not the corpus luteum. Option D) is incorrect because the corpus luteum of pregnancy is stimulated by luteinizing hormone (LH) from the pituitary gland, not by estrogen and progesterone secretion from the placenta. Option E) is incorrect because the corpus luteum is not formed if fertilization does not occur.
