Compromised receptivity of the endometrium is a major cause of unexplained infertility, implantation failure and subclinical pregnancy loss. Nine proteins were found to be differentially expressed between early- and mid- secretory phases of endometrium of infertile women. The expression of Ras-related protein Rap-1b, Protein disulfide isomerase A3, Apolipoprotein-A1 Apo-A1 , Cofilin-1 and RAN GTP-binding nuclear protein Ran were found to be significantly increased, whereas, Tubulin polymerization promoting protein family member 3, Superoxide dismutase [Cu-Zn], Sorcin, and Proteasome subunit alpha type-5 were significantly decreased in mid- secretory phase endometrium of infertile women as compared to early-secretory phase endometrium of infertile women. Validation of 4 proteins viz. Sorcin, Cofilin-1, Apo-A1 and Ran were performed in separate endometrial biopsy samples from infertile women. The up-regulated expression of Sorcin and down-regulated expression of Cofilin-1 and Apolipoprotein-A1, were observed in mid-secretory phase as compared to early-secretory phase in case of fertile women.

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. Menstrual Cycle. The female reproductive system prepares women for conception and pregnancy through two distinct, but highly integrated, cycles, the ovarian cycle and the endometrial cycle.
The human endometrium, under the influence of complex biological signals, undergoes cyclic changes in preparation for implantation and the initiation of pregnancy. An array of molecular activity, still poorly understood, gives rise to relatively consistent morphologic changes of the endometrium during each cycle. In an era of assisted reproductive technologies ART , there exists an ever-increasing demand to delineate these pathways in order to improve pregnancy rates.
Ultimately, success in the field of reproduction and fertility requires an understanding of these complex processes, from molecular to cellular to tissue, in both the healthy patient as well as in the setting of various pathologic states. This chapter will discuss the endometrial cycle with an emphasis on the secretory phase, including the molecular and biochemical components of endometrial receptivity and implantation.

Metrics details. Over the course of the last four decades, IVF has allowed an increasing number of infertile couples the chance to conceive. Considering the extensive research and advances in ART, too many IVF attempts still do not result in a successful pregnancy [ 1 , 2 ].
Several endometrial dating criteria have been commonly used in level in the secretory endometrium and the concentrations in serum [3, 16].

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.

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.
Normal Endometrium and Infertility Evaluation
The upper part of the uterus fundus is attached to the fallopian tubes while the lower part is connected to the vagina through the uterine cervix. Functions of the uterus include nurturing the baby, and holding it until the baby is mature enough for birth. The endometrium is hormone-responsive which means it changes in response to hormones released during the menstrual cycle. Following every menstrual period menses the endometrium grows to a thick, blood vessel-rich, glandular tissue layer, providing an optimal environment for a fertilized egg.

Richard A. Owings, Charles M. Quick; Endometrial Intraepithelial Neoplasia. Arch Pathol Lab Med 1 April ; 4 : — Data Sources. The research leading to the EIN criteria is based on molecular and progression data. The classification of endometrial lesions into benign hyperplasia BH and endometrial intraepithelial neoplasia EIN reliably separates the histologic features seen because of unopposed estrogen and those due to the accumulation of neoplastic mutations.
The EIN classification system is gaining widespread acceptance in diagnostic surgical pathology, clinical gynecology, and basic science fields. The key to its success lies in the integration of histologic findings to the underlying genetic changes in a manner that is useful for clinical management. Simply put, EIN is the histologic manifestation of an underlying molecular progression in endometrial carcinogenesis and is a lesion that can be diagnosed for purposes of therapeutic decisions.

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. It should be emphasised that the term EIN refers to the precursor dating of endometrioid adenocarcinoma and is endometrium from EIC, the dating of serous adenocarcinoma, which is discussed in detail later in this review. This is not surprising, as these two lesions are part of a spectrum without clearly defined boundaries.
It has been suggested that in biopsy specimens, these two lesions should be combined under the designation endometrioid neoplasia.

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.
