Background: Abnormal uterine bleeding AUB is a common gynecological complaint associated with considerable morbidity and significantly affects the patient’s family, personal and social life. The aim of the study was to analyze the histomorphological patterns of endometrium in patients presenting with AUB and also to determine the incidence of AUB in various age groups. Materials and Methods: This is a prospective study, conducted in the Department of Pathology, in a tertiary care teaching hospital, Mangalore from October till date. All cases of AUB with a probable endometrial cause were included in the study. Analysis was done in the form of percentages and proportions and represented as tables where necessary. Results: A total of cases were analyzed. Patients’ age ranged from years.
Secretory Phase and Implantation
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.

Endometrial Biopsy in Infertile Patients
Menstruation describes the female period. The menstruation cycle begins when a woman gets her periods. The menstrual blood which leaves her body are products shed from the uterus the uterine lining also called the endometrium. During the remainder of the menstrual cycle the uterine lining regrows. It does so in preparation for pregnancy, which occurs if the egg oocyte a woman releases about half way through her menstrual cycle is fertilised.

Thus, studies that clearly delineate which histologic parameters serve as the endometrium source of disagreement for pathologists provide a valuable framework for secretory refinement of the criteria for endometrial dating. Meanwhile, continued use of the criteria of Noyes et al for endometrial dating is recommended until more precise modalities for assessing the adequacy of endometrial maturation are available.

LPD is defined as endometrial histology inconsistent with the chronological date of the menstrual cycle, based on the woman’s next menses. It was first described.
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. In many histopathology laboratories, endometrial specimens account for a major proportion of the workload. Most specimens are taken because of abnormal uterine bleeding or other related symptoms, and the pathologist is expected to exclude an endometrial cancer or a precancerous lesion.
In some cases, a benign cause for abnormal uterine bleeding is identified, such as endometritis or endometrial polyp. In this review, I will outline my approach to the interpretation of endometrial biopsy specimens, especially concentrating on areas which, in my experience, create difficulties for pathologists. Endometrial biopsy specimens are now rarely taken to date the endometrium and to assess whether ovulation has occurred, as serum measurements of various hormones give equivalent or more information.
In this review, dating of the endometrium will not be discussed, as this has been dealt with in detail recently. In evaluating an endometrial biopsy specimen, an adequate clinical history is important, including the age of the patient and the reason for the biopsy.
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.
Morphologically, the endometrium is one of the most dynamic target tissues in women. Its cyclic structural changes mirror changes in metabolic functions, and both are regulated by ovarian estradiol and progesterone. Because of this interplay of structure, function, and ovarian hormonal stimuli, the endometrium is considered one of the most sensitive indicators of the hypothalamic-pituitary-ovarian hormonal axis. As a result, morphologic evaluation of the endometrium is used in diagnostic evaluation of infertile patients to determine whether ovulation is occurring Fig.
Schematic representation of steroid hormone-morphologic interactions during the endometrial cycle. Estradiol promotes endometrial proliferation, whereas after ovulation, progesterone converts estradiol-primed endometrium into secretory tissue. Postovulatory estradiol amplifies the progesterone effect, and after withdrawal of both estradiol and progesterone, the endometrial mucosa breaks down and regenerates within the period of menstruation. Steroid hormone control of endometrial, epithelial, stromal, and presumably endothelial cells is mediated by estrogen receptors and progesterone receptors.
These steroid receptors are specific proteins concentrated exclusively in the nuclei of both endometrial epithelial and stromal cells, as well as the endothelial cells of stromal capillaries. They have high affinity to bind estradiol and progesterone, respectively. This chapter contains a review of the technical procedures for handling endometrial tissues and a discussion of the morphologic aspects of the endometrium, focusing on the interpretation and understanding of the physiomorphology of the endometrial cycle.

This study will evaluate the utility of the endometrial biopsy as a tool for the routine evaluation of the luteal phase of women presenting for infertility evaluation. The study will establish whether the mid-luteal or late-luteal phase is the most appropriate time to perform an endometrial biopsy. The study will be conducted through the multi-center Reproductive Medicine Network.
Women with a history of infertility will be age matched to fertile women controls.

The lining epithelium contains glycogen rich subnuclear vacuoles in the early secretary phase. The vacuoles will be supranuclear in midsecretary phase. In the late secretary phase, the glands are saw toothed and serrated with luminal secretions. This is called predecidual change as these are the precursors of decidual cells in pregnancy. The endometrium is obtained for evaluation by a process called dilatation and curettage or by endometrial biopsy.
This is done to evaluate infertility or dysmenorrhea. Days early secretory phase glandular changes predominate days mid to late secretory phase stromal changes predominate.
