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. The glands show proliferative diagram and, by dating, there is no nuclear atypia.

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.

Hormonal Pathology of the Endometrium

Endometrial dating is not related to fertility status3. In a blinded study ERA classifies better than Noyes criteria. To test the validity of the dating criteria, change in basal body temperature was used to correlate endometrial dating with ovulation rather than onset of. It is asserted that examination of the endometrium during the secretory phase yields more information about the time of ovulation, degree of….

For the purposes of this study, histologic dating of the samples according to the criteria of Noyes et al1 was undertaken on 2 separate occasions Table I. Noyes criteria endometrial dating.

The present application claims priority of application Ser. The present invention relates generally to the fields of infertility, endometrial hyperplasia, assisted reproduction, and hormone replacement therapy for women, and methods of assessing and monitoring endometrial development in connection with diagnoses and therapies related to the same.

Many of these couples further pursue costly procedures using assisted reproductive technology ART in an attempt to overcome their unidentified problems. Yet, even with ART, only Also, the live birth rate decreases to Clearly, despite improvements in embryo quality and culture conditions, some women are still unable to become pregnant. Their infertility, as well as the infertility experienced by many women, is likely caused in part by implantation difficulties.

Thus, predictors of implantation potential are needed, both to better understand the causes of infertility in women and to improve the efficacy and reliability of embryo transfer. Despite over two decades of ART, no tools for endometrial evaluations exist which can adequately predict whether implantation will occur during any given ART cycle. The normal human menstrual cycle proceeds, on average, over the course of 28 days. However, menstrual cycle lengths in individual women vary considerably.

Their study, which analyzed , menstrual intervals recorded by more than women over extended periods, found similar variations during all periods of a woman’s reproductive life. This variability is generally a reflection of the varying length of the follicular phase as opposed to the luteal phase, which lasts a relatively constant and predictable 14 days.

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.

To determine whether biopsy caused early menstruation, the secretory phases of the 25 patients who had recorded temperatures in at least 2 cycles in addition to that in which the biopsy was taken were examined. Thus, studies that clearly delineate which histologic parameters serve as the greatest source of disagreement for pathologists provide a valuable framework for further refinement of the criteria for endometrial dating.

Nevertheless, there is no consensus regarding the most suitable period of the luteal phase for performing the biopsy. OBJETIVE: This study evaluated the correlation between the histological dating of two endometrial biopsies performed in the same menstrual cycle, on luteal phase days six and ten. Dating was done according to morphometric criteria, in which an endometrium sample is considered out of phase if the minimum maturation delay is one day.

Luteal phase. Female infertility. Evaluation of the luteal phase of regularly cycling women complaining of infertility is directed towards the evaluation of corpus luteum activity and the action of progesterone on the endometrium. Endometrial maturation, whose role in human reproduction was first recognized by Jones, 1 is evaluated by the Noyes criteria.

This study evaluated the correlation between the histological dating of two endometrial samples, obtained by biopsies performed on luteal phase days 6 and 10 of the same menstrual cycle. Twenty five regularly cycling healthy women, complaining of infertility for at least one year, voluntarily agreed to participate in the study group and gave their informed written consent. Blood samples were drawn from patients between days one and five of the menstrual cycle, for basal plasma levels of LH, FSH and prolactin, measured by immunofluorimetry normal ranges: FSH: 2.

A transvaginal ultrasonograph was also done to evaluate uterine echoes.
