The corpus luteum is a temporary endocrine structure that forms after ovulation from the ruptured follicle. It secretes progesterone to prepare the uterine lining for implantation and maintains the pregnancy until the placenta takes over this function. If implantation does not occur, the corpus luteum breaks down and degenerates. However, the release of hCG from the developing embryo signals to the corpus luteum to continue producing progesterone, preventing it from disintegrating and allowing for the necessary support for early pregnancy.
