Endometrial growth can be divided into two different phases, depending on the hormone that has a larger influence. The first is the proliferative phase, at which the endometrium increases it size thanks to the influence of estrogens in the ovary. The second is the secretory phase, where, thanks to the progesterone produced by the ovary, the endometrial lining finishes generating the adequate environment for embryo implantation.
