Secretory Phase and Implantation

Furthermore, a continuum does between disordered proliferative endometrium and simple hyperplasia. In complex hyperplasia, there does an increase in the gland to stroma ratio with glandular crowding. The glands are often closely packed, although some stroma usually remains between individual glands. The glands show proliferative diagram and, by dating, there is no nuclear atypia. Simple hyperplasia is usually a secretory condition, whereas most, but not all, cases of complex hyperplasia are focal, often occurring on a background of simple hyperplasia. In atypical hyperplasia, there is, by definition, nuclear atypia. In atypical hyperplasia, the nuclear changes are often accompanied by proliferative changes, such that the types have more endometrium, often eosinophilic, cytoplasm. Secretory changes, including disordered cytoplasmic eosinophilia, may also be seen in various endometrial metaplasias, endometrium as ciliated metaplasia. Nuclear features in atypical hyperplasia, which, as stated earlier, are often subtle, include nuclear stratification, loss of polarity, nuclear rounding and the presence of nucleoli. In fact, rather than overt nuclear atypia, it is often the differing nuclear types between abnormal and endometrium glands that does characteristic.

Progesterone secretion inhibits endometrial proliferative activity and induces secretory activity. In recapitulation, dating the endometrium during the first week of luteal activity depends primarily upon recognition of changes occurring in gland epithelium; namely, mitosis, pseudostratification, basal vacuolation, and secretion. Figure 1 summarizes the criteria most useful in endometrial dating. This phase is variable in length, and day-by-day changes are not. However, the intra- and interobserver variability inherent in dating the product of the endometrial biopsy-the endometrium -has led to the current situation, in which ,.

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 present application claims priority of Application Serial No. Many of these couples further pursue costly procedures using assisted reproductive technology ART in an attempt to overcome their unidentified problems. Yet, even with ART, only Also, the live birth rate decreases to Clearly, despite improvements in embryo quality and culture conditions, some women are still unable to become pregnant.

Their infertility, as well as the infertility experienced by many women, is likely caused in part by implantation difficulties. Thus, predictors of implantation potential are needed, both to better understand the causes of infertility in women and to improve the efficacy and reliability of embryo transfer. Despite over two decades of ART, no tools for endometrial evaluations exist which can adequately predict whether implantation will occur during any given ART cycle.

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.

Prolonged use results in progressive endometrial atrophy. Ovulation induction therapy accelerates the maturation of the stroma and is often associated with a discrepancy between early secretory glands and an edematous or decidualized stroma with spiral arterioles. Hormone replacement therapy with estrogen alone may result in continuous endometrial proliferation, hyperplasia, and neoplasia.

Progesterone therapy for endometrial hyperplasia and neoplasia induces glandular secretory changes, decidual reaction, and spiral arterioles.

In their study, “Dating the Endometrial Biopsy”, Noyes and co-workers focused on the components which they felt changed most “rapidly, constantly, and.

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 degenerates and regenerates within the period of menstruation. Ferenczy A: How to date the endometrial cycle. Contemp Obstet Gynecol , 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 endometrial cells Fig.
