Everyone would agree that functionality of the uterine lining is incredibly important for implantation of the blastocyst to take place. The methods that have been used in the past were indirect, assumptive and not reproducible. Researchers in Spain have created a new tool which has been shown to be promising for identifying molecular markers for uterine receptivity. Remarkably, as the blastocyst floats within the uterine cavity looking for a place to land, a dialog takes place between the blastocyst and the endometrium.

The hormonal preparation of the uterus plays a critical role each month in creating this environment in which the blastocyst can adhere to the endometrium in the hope that implantation will take place. The uterine lining undergoes changes during the two phases of the menstrual cycle that prepare it for blastocyst implantation. During the proliferative phase, it grows due to the increasing production of estrogen by the ovaries.

The second phase is called the secretory phase where the production of progesterone, produced by the corpus luteum, converts the endometrial lining to a secretory one, changing the cells to prepare for implantation a process called decidualization. Should implantation not take place, the hormone levels will fall, resulting in a shedding of the lining, which results in menses. Studying the mid-secretory phase is of great importance since the window of implantation WOI takes place then.

The sweet spot of WOI is approximately a 2-day period when the uterus is prepared to accept the implantation of a blastocyst. Conventionally, it was assumed that every woman had the same WIO, approximately days after ovulation so embryo transfers would be scheduled to take place during this time.
