Apart from a high level of metabolic and secretory activity there is also an upregulation of genes involved in the activation of the immune response. Email alerts New issue alert. In patients with thin endometrium, we tried to achieve the maximum thickness that had been observed on earlier scans, before starting progesterone.

Endometrial pattern and thickness associated with pregnancy outcome after assisted reproduction technologies. There has been considerable controversy concerning the value of endometrial thickness in the prediction of endometrial receptivity. The standard method of endometrial dating is the histological evaluation of an endometrial biopsy specimen Noyes et al. In this study, endometrial dating was closely related to menstrual dating in all examinations. Dating the endometrial biopsy.

  1. The uterine cervix was visualized with a speculum, the anterior cervical lip was grasped and the cervical os was cleaned with sterile dry gauze.
  2. Successfully reported this slideshow.
  3. Aberrant integrin expression in the endometrium of women with endometriosis.
  4. However, more studies are required to confirm these initial findings.


Therefore, some researchers have evaluated the role of endometrial volume as well as subendometrial and endometrial vascularization for predicting uterine receptivity. My approach to the interpretation of endometrial biopsies and curettings. Ovulation was confirmed using ultrasound and basal body temperature in all patients.




The test has been shown to be accurate and reproducible and does not have the limitation of inter cycle variability. Ultrasound evaluation was performed on the day of oocyte retrieval. This volume can be further analysed in several ways, such as navigation, multiplanar display, and surface rendering or volume calculation. In the menstrual cycle, the endometrium has no adhesive qualities until the implantation window phase, during which for a very short time, the endometrium allows the implantation of gestational sacs.

Accuracy and consistency are the hallmarks of a good diagnostic test. What is your impresion on this biopsy? However, conflicting results have been reported. When the tip of the device had reached the uterine fundus, the sheath was withdrawn, thus breaking the heat-seal. Ultrasound examination was performed on the first day of ovarian stimulation after pituitary down regulation.

In this study, the contrast enhancement effect of intrauterine saline infusion was more marked under intrauterine than transvaginal sonographic examination. Reprinted with permission Horjcadas et al.

The small vesicular echo-free spaces were visualized by intrauterine sonography in one of nine women examined in the early secretory phase, and in five of six patients in the mid-secretory phase. This aliquot was twice frozen and thawed to effect hemolysis. Many factors produced by the endometrium during this window have been proposed as molecular markers of a receptive endometrium. Colour Doppler energy imaging is a technology based on the total integral of energy frequency spectrum.

Assessment of endometrial receptivity. Saline contrast hysterosonographic assessment of endometrial abnormality is as accurate and well tolerated as hysteroscopy Widrich et al. The subjective assessment of overall image clarity was compared between transvaginal and intrauterine sonography. However, the specificity of endometrial volume was so low that it lacked of clinical value.

Conventionally, pulsed and colour Doppler have been used to assess uterine and endometrial blood flow. Correspondence to Manal A Eid. Obviously, such an invasive method is not acceptable in order not to damage the endometrium. Though we saw an improvement of results, the numbers in our study are not high enough to draw definite conclusions. Open in a separate window.

Endometrial biopsy interpretation for post graduate students in Pathology. Leukemia inhibitory factor expression in different endometrial locations between fertile and infertile women throughout different menstrual phases. All authors confirm that they have read and approved the final manuscript.

The volume was captured through the automatic sweep of the transducer over the region selected. Molecular phenotyping of human endometrium distinguishes menstrual cycle phases and underlying biological processes in normo-ovulatory women. The author declares that there are no financial and non-financial competing interests in relation to this manuscript.

Endometrial thickness measured by ultrasound scan in women with uterine outlet obstruction due to intrauterine or upper cervical adhesions. Human implantation is a highly complex and multifactorial process. Leukemia inhibitory factor enhances endometrial stromal cell decidualization in humans and mice.

The publisher's final edited version of this article is available at Fertil Steril. Therefore, dating casually the present study focuses on exploration of gp status in both endometrium and uterine flushing. The test contains genes that are differentially expressed between these profiles.

Endometrium - Libre Pathology

The study was approved by the local ethical committee of Kagawa Medical University, and standardized informed consent was obtained from each patient. The invasive nature of the test, the need for embryo vitrification and cost are some of its limitations. Rotation and translation of the sonographic planes provided exact frontal, sagittal and horizontal sections through the uterine cavity. You can change your ad preferences anytime. In each patient, serum oestrogen and progesterone concentrations were within normal limits, and neither endometrial nor uterine disorders were recognized.

Presentation Description
Endometrial Pathology

Therefore, a little nudge online the ideal method to predict endometrial receptivity has yet to be established. These data are consistent with the finding that inflammatory components negatively impact endometrial receptivity by targeting specific protein expression. Genomics of endometrial receptivity. More research is required to identify the factor s involved in implantation defects and how to best treat such problems before undergoing expensive or invasive therapies for infertility.

Endometrial tissue and uterine flushing were obtained. Much of the implantation process still remains to be unraveled. Human implantation is a complex process requiring synchrony between a healthy embryo and a functionally competent or receptive endometrium. Hydrosalpinges adversely affect markers of endometrial receptivity.

Conflicts of interest There are no conflicts of interest. Specialized software is used to analyze the microarray data. Support Center Support Center. Moreover, there is the difficulty in the interpretation of images obtained using the high-frequency probe, great online and particular training may be necessary.

Approach to endometrial biopsy
  • Background Endometrial receptivity is a crucial fact in human reproduction.
  • Cycles that occurred after laparoscopy were excluded.
  • Immunohistochemical analyses of estrogen receptor in endometrial adenocarcinoma using a monoclonal antibody.

Endometrial preparation methods for frozen-thawed embryo transfer are associated with altered risks of hypertensive disorders of pregnancy, placenta accreta, and gestational diabetes mellitus. We're creating a new version of this page. During the adhesive and invasive phases, the blastocyst approaches the epithelium, attaches itself to it, and the embryo trophoblast invades the deciduas.
