Which of the following statements about the corpus luteum is false? a. none of the other answer options is false. b. progesterone secreted by the corpus luteum maintains the uterine lining. c it is composed of follicle cells that remain in the ovary following ovulation. d. the corpus luteum is maintained first by fsh and then by hcg. e. if the egg is not fertilized then the corpus luteum degenerates.

The correct option is D.

Explanation:

The corpus luteum refers to the structure that is formed in an ovary after an ovum has been discharged; this structure degenerates if pregnancy does not occur. The formation and degeneration of corpus luteum occurs in a cycle. Many hormones are involved in this cycle, but the hormone that is initially responsible for the maintenance of the corpus luteum is LEUTEINIZING HORMONE (LH) not FSH. If pregnancy occur, then hCG hormone will support the work of LH and the two of them will work together.
