Although most board-certified reproductive endocrinologists agree on the major areas of the performance of infertility testing, there was significant variability in the details of the performance of most testing, especially with respect to physician age and geographic location. Biopsies can only provide a snapshot of the real situation in the endometrium, and sample bias is unavoidable because it is not applicable to take large numbers of samples. However, despite these advances, pregnancy rates are still relatively low and have not increased significantly in the last decade ;. These incidences in normal, fertile women are as high as the rates quoted for infertile populations, and call into question the standard criteria for defining this condition and evaluating therapies to correct it. In routine dating, the pathologist should avoid bias by evaluating the histologic section before reading the clinical information. Endometrial biopsy was the adequacy of noyes et al. Our findings indicate that an endometrial biopsy performed in the midluteal phase may detect a greater number of women with delayed endometrial maturation during the temporal window of embryo implantation. A single, well-timed progesterone determination appeared adequately to reflect the data obtained from serial samples in the same cycle.
Endometrial Dating Method Detects Individual Maturation Sequences During the Secretory Phase
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.
criticized the accuracy of endometrial dating using the criteria of Noyes and associates. If endometrial dating is accurate during the secretory phase, then it.
Nothnick, Robert N. Taylor and Monique Monard. This chapter will explore the latter phase of the menstrual cycle focusing on the secretory phase of the endometrium. In particular, focus will be on the mid-secretory endometrium and appropriate markers and hormonal environment for successful implantation. This will be put in the context of the luteal phase of ovulation and the hormonal support that progesterone provides.
We will also review pathologic states, such as endometriosis and related progesterone resistance, which affect mid-secretory phase and implantation. Finally, we will provide a detailed review of the literature on what the current state of knowledge is regarding receptivity and the microenvironment of the mid-secretory endometrium which is essential to implantation. Menstrual Cycle.
The female reproductive system prepares women for conception and pregnancy through two distinct, but highly integrated, cycles, the ovarian cycle and the endometrial cycle. 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.
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.

The assessment of endometrial receptivity has drastically changed since the establishment of the Noyes’ criteria for histologic dating in . Once the.
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.

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.

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. Simple hyperplasia is usually a secretory condition, whereas most, but not all, cases of complex hyperplasia are focal, often occurring on a background of simple hyperplasia.
In atypical hyperplasia, there is, by definition, nuclear atypia.
