Endometrial Biopsy

Human sexuality is the way people experience and express themselves sexually. Someone’s sexual orientation is their pattern of sexual interest in the opposite or same sex. Social aspects deal with the effects of human society on one’s sexuality, while spirituality concerns an individual’s spiritual connection with others. Sexuality also affects and is affected by cultural, political, legal, philosophical, moral , ethical , and religious aspects of life. Interest in sexual activity typically increases when an individual reaches puberty. Hypothesized social causes are supported by only weak evidence, distorted by numerous confounding factors.

The window of implantation has long posed as a challenge in understanding the exact synchronized cross talk that must take place in order for a developing embryo to be appropriately received by the endometrium. This is due mostly to the fact that it is difficult to study human models of implantation without sacrificing the potential for pregnancy.

For many who present with a diagnosis of infertility with an otherwise unexplained etiology, recurrent implantation failure or a displaced window of receptivity may be an underlying, silent cause. As assisted reproductive technology ART continues to advance and offer new scientific breakthroughs allowing greater insight and understanding to reproductive failure and infertility, endometrial receptivity testing may offer answers to struggling patients.

Innovations In Assisted Reproduction Technology. In order for pregnancy to occur, two events must take place: Fertilization: the moment the sperm fertilizes the oocyte. Implantation: the moment the developing embryo meets the uterus, creating a nest from which to grow and develop. Following fertilization, the developing embryo must embed itself within the endometrium.

Secretory Phase and Implantation

It is a molecular diagnostic test that allows knowing the state of receptivity of the endometrium. Thanks to this test, the chances of implantation failures are reduced, since it allows you to determine the appropriate day to perform the embryo transfer. Endometrial receptivity is necessary to achieve pregnancy, because although embryos of very good quality are achieved, if they are transferred at an inappropriate time in the cycle, implantation failure is likely to occur.

included in the customized microarray (endometrial receptivity array (ERA]), and the other to be analyzed by. ERA to train the predictor for endometrial dating.

With embryo culture conditions continuing to improve, the rate-limiting step in assisted reproduction technology ART remains the implantation of the embryo in the endometrium Macklon et al. The human endometrium is a unique dynamic tissue that cyclically sheds, regenerates and undergoes complex molecular, cellular and functional changes in response to sex hormones, preparing for embryo implantation Psychoyos , Salamonsen As an increasing number of women postpone their motherhood Baird et al.

It uses the methylation status of CpG sites in the human genome to calculate an epigenetically based biological age of an individual also called methylation age or DNAm age , which has shown to be remarkably closely correlated with chronological age irrespective of the DNA source within the organism. A discrepancy between biological and chronological age could potentially be attributed to pathological processes, underlying disease or lifestyle choices Horvath

A decidual cast occurs when the lining of the endometrium is sloughed off in one going by ovulation date) and also causes pregnancy tests to be negative.

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. Once considered an important cause of infertility, LPD has become the subject of debate, with some experts questioning its very existence. Unclear terminology describing this disorder is part of the problem, making it difficult to definitively diagnose the deficiency or determine its incidence.

Further, while reasonable consensus exists that endometrial biopsy is the most reliable diagnostic tool, concerns remain about its timing, repetition, and interpretation. It was first described by Jones in LPD may be caused by deficient progesterone secretion from the corpus luteum or failure of the endometrium to respond appropriately to ovarian steroids TABLE. Most experts believe LPD is a defect of corpus luteum progesterone output—both in amount and duration—resulting in inadequate stimulation of the endometrium for implantation of the blastocyst FIGURE 2.

Normal embryonic implantation depends on a properly functioning luteal phase, which, in turn, requires optimal secretion of follicle-stimulating hormone FSH and adequate follicular development during the follicular phase. Other requirements are a satisfactory luteinizing hormone LH surge during ovulation and continuous tonic LH pulses during the luteal phase of the cycle.

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.

The endometrium is typically biopsied because of abnormal bleeding. Endometrial hyperplasia and endometrial carcinoma are dealt with in separate articles. An overview of gynecologic pathology is in the gynecologic pathology article. Other indications: [2]. An increased gland density is seen focally, at the edge of one tissue fragment, in association with tearing of the stroma compression artifact.

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.

However, the intra- and interobserver variability inherent in dating the product of the endometrial biopsy-the endometrium-has led to the current.

Endometrial thickness is a commonly measured parameter on routine gynecological ultrasound and MRI. The appearance, as well as the thickness of the endometrium, will depend on whether the patient is of reproductive age or postmenopausal and, if of reproductive age, at what point in the menstrual cycle they are examined. The endometrium should be measured in the long axis or sagittal plane, ideally on transvaginal scanning, with the entirety of the endometrial lining through to the endocervical canal in view.

Care should be taken not to include hypoechoic myometrium or intrauterine fluid in this measurement. The normal endometrium changes in appearance as well as in thickness throughout the menstrual cycle:. The designation of normal limits of endometrial thickness rests on determining at which thickness the risk of endometrial carcinoma is significantly increased.

Whilst quantitative assessment is important, endometrial morphology and the presence of risk factors for endometrial malignancy should also be taken into account when deciding whether or not endometrial sampling is indicated.

Metrics details. It is postulated that women suffered from recurrent implantation failure RIF have different endometrial receptivity compared to those who experienced with idiopathic recurrent miscarriage RM. MUC1 expression in both luminal and glandular epithelium in women with RIF were significantly lower than that in women with RM and fertile controls. Decreased MUC1 expression were not significantly associated with age, BMI, gravidity, parity, cycle length, progesterone level and previous miscarriage.

Endometrium is critical for a successful implantation [ 1 ]. For only a short period of time during mid-luteal phase, the endometrium becomes receptive to the embryo to implant. During this implantation window, endometrium will equip with adhesion ligands but remove inhibitory factors to facilitate the implantation process [ 3 ]. Many molecules have been proposed as markers for endometrial receptivity, but there is as yet no consensus on which marker is the best.

Most of previous studies only focused on a single marker; often the endometrial specimens were not precisely timed; few studies compared the RIF and RM with fertile control at the same time. These may be the potential reasons of the contrasting observation. In addition, the effects of various confounding factors on the result were not examined as well. Some endometrial receptivity markers expressed in epithelium and others expressed in stroma of the endometrium.

Fertile women showed a higher level of endometrium MUC1 expression than infertile patients [ 6 ].

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

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.
