What is the Origin of Endometrial Receptivity?

The term is a compound of "endometrial," referencing the inner uterine layer, and "receptivity," denoting the capacity to receive or admit. This concept emerged from decades of reproductive research focused on identifying the precise physiological conditions required for successful embryo-uterine dialogue. It highlights the active, selective role of the maternal tissue in the implantation process, moving beyond a passive view of the uterus.

What is the Mechanism of Endometrial Receptivity?

The mechanism is hormonally driven, beginning with estrogen-induced endometrial proliferation in the first half of the menstrual cycle. Following ovulation, the corpus luteum secretes high levels of progesterone, which then induces a series of critical morphological and molecular changes, transforming the proliferative endometrium into a secretory and receptive state. These changes include the expression of specific adhesion molecules and growth factors on the surface epithelial cells, which facilitate the physical attachment and subsequent invasion by the blastocyst. Optimal receptivity requires precise progesterone signaling timing and duration.

Endometrial Receptivity

Meaning

Endometrial receptivity refers to the transient state of the uterine lining, the endometrium, during which it is optimally prepared to allow for the attachment and implantation of an embryo. This critical window, known as the “window of implantation,” is a highly synchronized event essential for successful pregnancy. It is regulated by a precise, sequential interplay of ovarian steroid hormones, primarily estrogen and progesterone. Clinical assessment of receptivity is a key component in reproductive endocrinology and in vitro fertilization protocols.
