Nanette Santoro, Laura T. To examine the relationship between endometrial histological maturation and reproductive hormones, we studied 11 fertile women, aged 18—37 yr. All participants had had at least 1 previous pregnancy and cycled regularly, every 25—35 days. Women collected daily, first morning voided urine for measurement of estradiol and progesterone metabolite excretion, estrone conjugates E1c , and pregnanediol glucuronide Pdg , respectively, throughout the cycle of study.
Hormones were normalized for creatinine. Between 7—9 days after home detection of a LH surge Sure Step , participants underwent an endometrial biopsy using a small bore Pipelle catheter. Tissue was prepared for histological and biochemical analyses. The histological analysis is reported herein. Endometrium was dated by 3 authors N. Final dating was agreed upon based upon the method of Noyes et al. E1c and Pdg were integrated throughout the cycle using the trapezoidal rule, and correlations were sought between deviation from expected histology based upon urinary hormones and LH surge and integrated hormone values.
No relationship could be found between histological lagging of endometrial maturation and lower excretion of E1c.

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.

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.
Secretory phase endometrium
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.

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.

Effect of hCG on Receptivity of the Human Endometrium
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. If the fertilization does not occur, the endometrium breaks down, leaving only the bottom layer basal layer and many open blood vessels.
However, histologic dating of the endometrium as a diagnostic tool of endometrial receptivity has been questioned. Methods: This is a.
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. When fertilisation occurs, the lining stays in place to nourish the fertilised egg.
Women begin menstruation at an average age of 13 called menarche and on average continue menstruating till age 51 called menopause. Menstruation involves highly complex hormonal interactions. The key hormones involved in menstruation are oestrogen and progesterone produced by the ovaries and luteinising hormone and follicle stimulating produced by the pituitary gland , under the influence of hormones secreted by the hypothalamus.
The interactions between these organs are referred to as the hypothalamic-pituitary-ovarian axis HPO axis. Information on re-publishing of our images. It typically occurs in 28 day cycles, so a woman generally gets her period every 28 days.

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.
These molecules were localized by avidin-biotin-complex procedure in 26 endometria dated to midproliferative, late proliferative, early secretory, midsecretory.
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.
The endometrium is one of the major factors involved in embryo implantation. However, the process involved and the underlying molecular mechanisms that enable the endometrium to enter the receptive phase are still not fully clear. Many researchers have explored various methods for investigating endometrial maturation during the menstrual cycle.
Well-dated endometrial tissue is required in order to study the molecular features of the endometrium during the menstrual cycle, and inadequate dating can lead to misinterpretation even if the structure of a research study is excellent.

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.
Hysteroscopically we were able to define five different phases in the menstrual cycle: early proliferative, late proliferative, early secretory, late secretory, and.
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.
