Normal Endometrium and Infertility Evaluation

The endometrium is typically biopsied because of abnormal bleeding. Endometrial hyperplasia and endometrial carcinoma are dealt with in separate articles. An overview of gynecologic pathology is in the gynecologic pathology article. Other indications: [2]. An increased gland density is seen focally, at the edge of one tissue fragment, in association with tearing of the stroma compression artifact.

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.

Endometrial lining thickness chart An endometrial thickness of less than 7 mm decreases the pregnancy rate in in vitro fertilization by an odds ratio of approximately 0. On tamoxifen: Thickness should be less than 6mm. According to the uterine lining thickness chart, the risk of cancer is extremely low if the thickness is under 11mm.

When there is estrogen stimulation to lining of the uterus, the endometrium would grow thick. Thickened Endometrium Diagnosis An ultrasound evaluation of the uterine lining may be used as a screening tool. The types vary by the amount of abnormal cells and the presence of cell changes. Days of the menstrual cycle At this point, the endometrial layer is about mm thick. According to the American College of Obstetricians and Gynecologists ACOG , this most often happens due to a specific hormonal imbalance—an excess of estrogen, which causes the thickening of the endometrium, in combination with an absence of progesterone that can result if ovulation doesn’t take place.

Correlation between endometrial dating of luteal phase days 6 and 10 of the same menstrual cycle.

The endometrial biopsy involves scraping and examining a sample of tissue from the lining of the uterus endometrium. The procedure makes it possible for the physician to determine if ovulation has occurred, and whether the lining of the uterus has undergone the changes necessary for the implantation of a fertilized egg and the support of an early pregnancy.

An endometrial biopsy can also detect an infection or inflammation of the endometrium endometriosis. The endometrial biopsy is usually performed one to four days prior to menstruation. In a woman with a day cycle, it is usually scheduled for days

Endometrial dating and determination of the window of implantation in healthy fertile women.

The test is usually performed days after ovulation. If the pregnancy test is negative the biopsy will be performed. If the pregnancy test is positive the biopsy will not be done and further instructions will be given. If you are a recurrent pregnancy loss patient you will be asked to abstain from intercourse during the work-up phase.

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.

A major proportion of the workload in many histopathology laboratories is accounted for by endometrial biopsies, either curettage specimens or outpatient biopsy specimens. The increasing use of pipelle and other methods of biopsy not necessitating general anaesthesia has resulted in greater numbers of specimens with scant tissue, resulting in problems in assessing adequacy and in interpreting artefactual changes, some of which appear more common with outpatient biopsies.

In this review, the criteria for adequacy and common artefacts in endometrial biopsies, as well as the interpretation of endometrial biopsies in general, are discussed, concentrating on areas that cause problems for pathologists. An adequate clinical history, including knowledge of the age, menstrual history and menopausal status, and information on the use of exogenous hormones and tamoxifen, is necessary for the pathologist to critically evaluate endometrial biopsies. Topics such as endometritis, endometrial polyps, changes that are induced by hormones and tamoxifen within the endometrium, endometrial metaplasias and hyperplasias, atypical polypoid adenomyoma, adenofibroma, adenosarcoma, histological types of endometrial carcinoma and grading of endometrial carcinomas are discussed with regard to endometrial biopsy specimens rather than hysterectomy specimens.

The value of ancillary techniques, especially immunohistochemistry, is discussed where appropriate.

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.
