The endometrial tissue is a sensitive target for steroid sex hormones and is able to modify its structural characteristics with promptness and versatility. This article discusses briefly endogenous hormonal effects cyclic changes, luteal phase defect, unopposed estrogen effect and describes the histologic patterns encountered in the most commonly used hormone therapies: oral contraceptives, ovulation stimulation, hormone replacement therapy, and antitumoral hormone therapy. Oral contraceptives exert a predominant progestational effect on the endometriun, inducing an arrest of glandular proliferation, pseudosecretion, and stromal edema followed by decidualized stroma with granulocytes and thin sinusoidal blood vessels.

Histologic Dating of the Endometrium: Accuracy, Reproducibility, and Practical Value

Engman is a fellow in reproductive endocrinology and infertility, University of Connecticut School of Medicine, Farmington, Conn. Disagreement about the cause, true incidence, and diagnostic criteria of this condition makes evaluation and management difficult. Here, 2 physicians dissect the data and offer an algorithm of assessment and treatment. Despite scanty and controversial supporting evidence, evaluation of patients with infertility or recurrent pregnancy loss for possible luteal phase deficiency LPD is firmly established in clinical practice.

Although observational and retrospective studies have reported a higher incidence of LPD in women with infertility and recurrent pregnancy losses than in fertile controls, 1 – 4 no prospective study has confirmed these findings. Furthermore, studies have failed to confirm the superiority of any particular therapy.

Objective: To determine the effect of serum P on endometrial histology in stimulated cycles. Design: Histologic dating was correlated with the endocrine and.

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.

A total of patients who underwent hysteroscopic assessment of the endometrium and then became pregnant, was analysed retrospectively to explore the relationship between endoscopic findings and early phase pregnancy outcome after implantation. Histological examination of the endometrium and assay of serum progesterone and oestrogen were carried out simultaneously with hysteroscopy. Of patients, 12 were excluded. Of the remaining patients, 62 Of pregnancies, persisted successfully to live birth, but 42 ended in early pregnancy loss.

In conclusion, our data suggest that the hysteroscopic appearance of the mid-secretory endometrium at this stage of the menstrual cycle is a better prognostic factor for pregnancy outcome than hormonal data.

The reproducibility of integrin expression in the endometrium allows a complementary approach to histologic dating for the evaluation of endometrial receptivity.

Leyendecker, M. Herbertz, G. Kunz, G. METHODS: Normal uteri and uteri with adenomyosis obtained by hysterectomy, excised endometriotic lesions and menstrual blood of women with and without endometriosis were used. RESULTS: With respect to the parameters studied there was a fundamental difference between the cyclical patterns of the basalis and the functionalis of the eutopic endometrium. The endometrium of endometriotic and adenomyotic lesions mimicked the cyclical pattern of the basalis.

The peristromal muscular tissue of endometriotic and adenomyotic lesions displayed the same cyclical pattern of ER and PR expression as the archimyometrium.

Normal Endometrium and Infertility Evaluation

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.

The utility of histological dating of endometrium in the evaluation of infertile couples is uncertain. Design: Prospective multicenter study, with subjects randomly.

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.

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.

Histologic dating of the endometrium: Accuracy, reproducibility, and practical value

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.

Histologic dating of an endometrial sample is the gold standard for evaluation of the corpus luteum. Two main treatment strategies have been suggested.

Patients and Methods: A novel method was used for endometrial dating, with parameters including menstrual cycle days, Noyes histological criteria, along with immunohistochemical expression pattern of estrogen and progesterone receptors and proliferation marker Ki Results: Endometrial maturation varied individually, occurring 1. Comparison of histological maturation with clinical days after ovulation showed a delay of about 2 days.

Conclusion: Endometrial maturation requires 8 days, rather than the expected 6 days, to reach the histological mid-secretory phase. This is not a delay and is also seen in fertile patients. The new analysis method used is superior to that using Noyes criteria alone and provides a better basis for determining conditions for optimal timing of embryo transfers.
