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.

Published online January 1, Then, the PR, the integrin beta3, and COX-2 which were clearly expressed in the luteal phase was with endometrial samples were obtained from 20 cases of normal patients group 1 and 25 cases with endometriosis group 2 after confirming the day of ovulation by sex steroid level measurements days after ovulation. RESULTS: In the regular menstruation group the expression of ER showed a tendency to be increased in the proliferative phase and decreased in the secretory phase, and was the highest in the proliferative phase.
However, PR in the stromal cells showed no change in the entire menstrual cycle while in the epithelial cells, PR reached a peak in the late proliferative phase and was almost absent in the secretory phase.

Morphologically, the endometrium is one of the most dynamic target tissues in women. Its cyclic structural changes mirror changes in metabolic functions, and both are regulated by ovarian estradiol and progesterone. Because of this interplay of structure, function, and ovarian hormonal stimuli, the endometrium is considered one of the most sensitive indicators of the hypothalamic-pituitary-ovarian hormonal axis.
As a result, morphologic evaluation of the endometrium is used in diagnostic evaluation of infertile patients to determine whether ovulation is occurring Fig. Schematic representation of steroid hormone-morphologic interactions during the endometrial cycle.

Implantation occurs during a specific period of the menstrual cycle, known as the window of implantation between day 6 and day 10 of the cycle, following the luteinizing hormone surge , and is dependent on a synchronized dialogue between the embryo and endometrium. This dialogue is mediated by specific biochemical factors, including hormones, growth factors, enzymes, integrins and cytokines 1 — 3.
Leukemia inhibitory factor LIF , which is a multifunctional protein that belongs to the interleukin 6 cytokine family, exerts numerous regulatory actions on various domains of cellular function 4. LIF was initially reported to induce macrophage differentiation in M1 murine myeloid leukemic cells, and to suppress their proliferation in vitro 5. LIF was later examined in transgenic mice, and was identified as the first necessary cytokine for implantation 6 , 7. Furthermore, LIF expression has been detected in both the embryo and endometrium, and its role expands from blastocyst development and endometrial differentiation to blastocyst attachment and invasion of the endometrium 4 , 8.
LIF exerts its actions by interacting with its receptor, which is a heterodimer composed of two transmembrane proteins, LIF receptor LIF-R and glycoprotein gp 9 — LIF is initially connected to LIF-R with low-affinity binding, which in turn induces dimerization with gp, leading to a high affinity receptor 1 , 4 , 12 , The presence of LIF and LIF-R in endometrial cells, alongside alterations in their expression levels during the menstrual cycle, supports their decisive role in the normal implantation process 18 , LIF expression is maximized in endometrial cells during the mid luteral phase 8 , 20 , LIF concentration is maximized between days 7 and 12 post ovulation, whereas the levels of LIF-R and gp have been reported to peak between days 19 and 25 of the menstrual cycle 22 — The increased expres sion of LIF and its receptors during the mid secretory phase coincides with the implantation window, thus indicating the significance of this cytokine for endometrial receptivity Despite the fact that a decisive role has been recognized for LIF in animal implantation, few studies have compared LIF expression patterns between fertile and infertile women.
Furthermore, a review of the literature indicates that no data is available regarding the expression patterns of LIF-R in the epithelial and stromal cells of infertile women during the implantation window.

Furthermore, a continuum does between disordered proliferative endometrium and simple hyperplasia. In complex hyperplasia, there does an increase in the gland to stroma ratio with glandular crowding. The glands are often closely packed, although some stroma usually remains between individual glands.

Engman is a fellow in reproductive endocrinology and infertility, University of Connecticut School of Medicine, Farmington, Conn. Disagreement about the cause, true incidence, and diagnostic criteria of this condition makes evaluation and management difficult. Here, 2 physicians dissect the data and offer an algorithm of assessment and treatment. Despite scanty and controversial supporting evidence, evaluation of patients with infertility or recurrent pregnancy loss for possible luteal phase deficiency LPD is firmly established in clinical practice.
Although observational and retrospective studies have reported a higher incidence of LPD in women with infertility and recurrent pregnancy losses than in fertile controls, 1 – 4 no prospective study has confirmed these findings. Furthermore, studies have failed to confirm the superiority of any particular therapy. Once considered an important cause of infertility, LPD has become the subject of debate, with some experts questioning its very existence.
Unclear terminology describing this disorder is part of the problem, making it difficult to definitively diagnose the deficiency or determine its incidence. Further, while reasonable consensus exists that endometrial biopsy is the most reliable diagnostic tool, concerns remain about its timing, repetition, and interpretation. It was first described by Jones in

Patients and Methods: A novel method was used for endometrial dating, with parameters including menstrual cycle days, Noyes histological criteria, along with immunohistochemical expression pattern of estrogen and progesterone receptors and proliferation marker Ki Results: Endometrial maturation varied individually, occurring 1.

The human endometrium, under the influence of complex biological signals, undergoes cyclic changes in preparation for implantation and the initiation of pregnancy. An array of molecular activity, still poorly understood, gives rise to relatively consistent morphologic changes of the endometrium during each cycle.
