1. Histologic dating is most precise in the postovulatory secretory phase, as the follicular phase can be highly variable in length. Furthermore, proliferative phase.

The endometrium lines the uterine corpus and displays two chief constituents – the endometrial glands and endometrial stroma. The inactive, prepubertal endometrium shows a cuboidal to low columnar epithelium that lines the surface and the underlying glands. The appearance greatly resembles the inactive endometrium seen in postmenopausal women, as both prepubertal and postmenopausal endometria do not exhibit any proliferative or secretory changes that are hormone dependent.

The endometrium in the reproductive female may be considered to comprise of a deeper basal layer and a superficial functional layer. The functional layer is subdivided into two strata – the compactum towards the surface and the spongiosum towards the basalis. With the onset of menarche, the menstrual cycle follows three well-defined phases, each exhibiting a distinct morphology.

The superficial functional layer undergoes necrosis and is accompanied by a neutrophilic infiltrate. During the proliferative phase the endometrial glands, stroma and vascular endothelium all proliferate leading to an increased volume of the endometrium. The glands are lined by a stratified columnar epithelium with interspersed ciliated cells. The epithelium contains mitotic cells and increase in tortuosity in the mid and late proliferative phase.

The stromal edema is most marked at the mid-proliferative phase.

Bentley, George L. Mutter and Stanley J. The mucosal lining of the uterus consists of glands, stroma, and blood vessels. The function of the endometrium is to form a receptive site for pregnancy.

While histologic dating of the endometrial biopsy remains the gold standard for most practitioners, no prospective trial has ever demonstrated that women with.

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.

Objective: To evaluate the histology and histochemistry of endometrium in dysfunctional uterine bleeding DUB. Materials and Methods: This was a prospective study conducted in Regional Institute of Medical Sciences, Imphal during the period between 1 st December and 31 st August A total of 50 cases of DUB and another ten matched normal subjects were selected.

Endometrial samples taken between the 21 st and the 24 th day of the menstrual cycle and at random for continuous vaginal bleeding were studied with conventional H and E, periodic acid schiff and alcian blue stains. Conclusion: The commonest types of endometrium in DUB are proliferative and secretory endometrium is seen in all the normal subjects. Users Online:

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 dating can be performed both before and after ovulation.
