The uterine cycle refers to changes that occur in the endometrial lining of the uterus. In which phase of this cycle does the corpus luteum begin to produce progesterone?

Secretory After ovulation, the corpus luteum begins to produce progesterone; this hormone causes the uterine lining to become rich in nutrients in preparation for pregnancy. During the menstrual phase of the uterine cycle, the uterine lining is shed because of low levels of progesterone and estrogen. When estrogen levels are high enough, the endometrium begins to regenerate. Estrogen stimulates blood vessels to develop. The blood vessels, in turn, bring nutrients and oxygen to the uterine lining, which begins to grow and become thicker. The proliferative phase ends with ovulation on day 14. Without estrogen and progesterone to maintain the blood vessel network, the uterine lining becomes ischemic.

Which of the following statements best expresses the role of the corpus luteum?

The corpus luteum secretes progesterone to promote the preparation of the endometrium for implantation. The mature ovum is released from the ovary, resulting in the corpus luteum. Progesterone is produced by the corpus luteum. Estrogen is secreted by the ovaries. Glycogen is secreted by the endometrial glands during the luteal phase. Luteinizing hormone is not a product of the corpus luteum.
