The corpus luteum is a transient endocrine organ that functions by secreting the hormone progesterone to prepare the uterus for pregnancy, as established in [1], [2], and [3]. The relationship is further defined by the fact that the corpus luteum's breakdown leads to a drop in progesterone levels, triggering menstruation [4], [5], and [6].

claimThe corpus luteum is a transient endocrine organ that primarily secretes progesterone to prepare the estrogen-primed endometrium for implantation of the fertilized ovum.
claimThe human corpus luteum secretes relaxin, oxytocin, and progesterone, according to a 1989 study by Khan-Dawood et al. published in the Journal of Clinical Endocrinology & Metabolism.
measurementPeak vascularization of the corpus luteum is achieved eight or nine days after ovulation, which corresponds to the time of expected implantation and peak serum levels of progesterone and estradiol.
claimBasal vacuolization at the base of endometrial cells in a formalin-fixed specimen confirms the formation of a functional, progesterone-producing corpus luteum.
measurementPeak vascularization of the corpus luteum is achieved approximately eight or nine days after ovulation, which corresponds to the time of expected implantation and peak serum levels of progesterone and estradiol.
claimProgesterone secretion in the human corpus luteum is pulsatile, as evidenced by a 1984 study by Filicori, Butler, and Crowley published in the Journal of Clinical Investigation.
claimThe corpus luteum is a transient endocrine organ that primarily secretes progesterone to prepare the estrogen-primed endometrium for implantation of the fertilized ovum.
claimIf the corpus luteum is not rescued by pregnancy, it undergoes atresia, and the resulting progesterone withdrawal causes menses.
claimIn the absence of pregnancy, steroid hormone levels fall due to declining corpus luteum function, and progesterone withdrawal results in increased coiling and constriction of the spiral arterioles, leading to menstruation.

claimThe placenta secretes progesterone after it develops, which supports the corpus luteum and maintains elevated progesterone levels throughout pregnancy to prevent the production of additional eggs.
claimThe corpus luteum breaks down if a woman does not become pregnant, which lowers progesterone levels and triggers menstruation.
claimThe corpus luteum, a temporary endocrine gland produced by the female body after ovulation during the second half of the menstrual cycle, secretes progesterone.

claimAfter ovulation, the ruptured follicle transforms into the corpus luteum, which secretes progesterone.
claimIf an egg is fertilized and implants, the body produces human chorionic gonadotropin (hCG), which signals the corpus luteum to continue secreting progesterone to maintain the uterine lining and support early pregnancy.
claimIf an egg is not fertilized, the corpus luteum breaks down, causing a drop in progesterone levels that triggers the shedding of the uterine lining and the start of the next menstrual cycle.

claimThe corpus luteum produces estrogen and high amounts of progesterone to prepare the uterine lining for embryo implantation.
measurementIf pregnancy occurs, the corpus luteum produces progesterone until approximately 10 weeks of gestation.
claimProgesterone, manufactured by the corpus luteum, is the hormone responsible for changes in the uterus that support a fertilized egg during the luteal phase.

procedureThe luteal phase begins immediately after ovulation, during which the empty ovarian follicle develops into the corpus luteum, which secretes estrogen and progesterone to prepare the uterus for a fertilized egg.
claimFollowing ovulation, the empty ovarian follicle develops into the corpus luteum, which secretes estrogen and progesterone.
