Which of the following is not true regarding the corpus luteum? Presence of HCG prevents the corpus luteum from secreting hormones.
Answer and Explanation: The correct answer is d. The corpus luteum releases progesterone, which is a hormone required for the thickening and maintenance of the endometrium....
Function. The primary purpose of the corpus luteum is to pulse out hormones, including progesterone. Progesterone is required for a viable pregnancy to occur and to continue. Progesterone helps the uterine lining, known as the endometrium, to thicken and become spongy.
The corpus luteum secretes estrogens and progesterone. The latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. If the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.
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.
The primary hormone produced from the corpus luteum is progesterone, but it also produces inhibin A and estradiol.
If you're pregnant, your corpus luteum usually goes away around week 12, when the placenta starts making enough progesterone to keep the fetus healthy. If the egg doesn't get fertilized, your corpus luteum usually goes away 10 days after the egg left your ovary.
The corpus luteum secretes progesterone, which is a steroid hormone responsible for the decidualization of the endometrium (its development) and maintenance, respectively. It also produces relaxin, a hormone responsible for softening of the pubic symphysis which helps in parturition.
