In the nonpregnant state, the hormonal secretion of the corpus luteum gradually declines, ultimately leading to the breakdown of the corpus luteum and menstruation. The corpus albicans, which is the remnant of the corpus luteum, has no hormonal function. The endometrium does not secrete hCG, and the zygote cannot become hormonally active until it has implanted in the uterine wall.
