Histologic Dating of the Endometrium: Accuracy, Reproducibility, and Practical Value
Study record managers: refer to the Data Element Definitions if submitting registration or results information. After routine time transfer in the frozen embryo transfer cycle, the standard of histological dating were determined according to the pregnancy outcome of the FET cycle. Day 5 blastocysts were transferred with this strategy in natural cycles. Information from the National Library of Medicine Choosing to participate in a study is an important personal decision.

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. From menstrual cycle day nine onwards, follicular diameter 7 and endometrial thickness 8 were measured daily by transvaginal ultrasound.
When the dominant follicle reached at least 16 mm, daily plasma LH level measurements were started, until an LH peak was demonstrated. In the first of these, the catheter was introduced with its subterminal orifice directed to the right uterine wall and in the second, to the left.
Synchronous development of the endometrium to achieve a receptive state and of the embryo is essential for successful implantation and ongoing pregnancy. Endometrial receptivity exists only for a finite time in a menstrual cycle and the endometrium is refractory to embryo implantation outside of this window. Administration of hormones to stimulate multifollicular development within the ovary, integral to the majority of assisted reproduction ART protocols, dramatically alters the hormonal milieu to which the endometrium is exposed versus normal menstrual cycles.
Endometrial maturation may be profoundly affected by this altered endocrine environment. Compare endometrial histology in fertile women, fertile women undergoing hormonal stimulation for oocyte donation and infertile women undergoing fresh embryo transfers in an ART cycle with further comparisons between women who did or did not become pregnant. Examine the presence of leukocytes and markers of endometrial maturation.

In the same set of endometrial biopsies, the accuracy of the endometrial receptivity array diagnostic tool was superior to dating by endometrial histology, and was reproducible in the same patients 29—40 months later.

Chapter 8 Pathology of Reproductive Endocrine Disorders. An appreciation of the relationship between form and function is important for understanding of female reproduction. An awareness of histologic changes associated with both the normal ovulatory cycle and reproductive diseases allows the physician a better understanding of pathophysiology and potential treatment. This chapter begins with an examination of the histologic changes in the endometrium associated with a normal ovulatory cycle.
This is followed by an illustrated survey of common gynecologic diseases of the reproductive organs that are most likely to present to the reproductive surgeon. The endometrium is functionally divided into two layers: the basalis and the functionalis. Both layers are composed of stroma and glands. The stroma is composed of stromal cells, vessels, and white blood cells thought to be lymphocytes or macrophages. Cyclic changes occur in both endometrial glands and stroma in response to a changing endocrine environment.
Endometrial dating refers to the determination of how closely the histologic characteristics of the endometrium match what is expected on the corresponding day of the menstrual cycle. In the past, this approach was one of the standard tests in an investigation of causes of infertility and pregnancy loss. However, the accuracy of this test has been questioned because abnormal results can be observed in cycles that eventually prove to result in a viable pregnancy.

Endometrial biopsy is frequently used to evaluate abnormal uterine bleeding. It is a relatively quick and cost-effective way to sample the endometrium to allow for direct histological evaluation of the endometrium and is essential to have as endometrial cancer is the fourth most common cancer among women, and The American Cancer Society estimates that there will be new cases of uterine cancer and 12, related deaths in Endometrium: the lining of the uterine cavity.
It is a layer of glandular epithelium and stroma that changes thickness during the cycle. Cervix: the cervix is the most inferior part of the uterus. The cervical canal connects the uterus to the vagina.
