Progesterone is essential for preparing the endometrium for the implantation of a fertilized ovum, as evidenced by its role in the secretory phase [1] and its secretion by the corpus luteum [2], [3]. Furthermore, the peak levels of progesterone coincide with the timing of expected implantation [4], [5], [6].
