Endometrial biopsy. Common office procedures. Textbook of Family Medicine. Philadelphia, PA: Elsevier Benign endometrial proliferations mimicking malignancies: a review of problematic entities in small biopsy specimens. Benign proliferations that mimic malignancies are commonly encountered during the course of assessment of small and fragmented endometrial samples. Although benign, endometrial epithelial metaplasias often coexist with premalignant or malignant lesions causing diagnostic confusion. The difficulty with mucinous metaplasia lies in its distinction from atypical mucinous glandular proliferations and mucinous carcinomas, which are associated with significant interobserver variability. Papillary proliferation of the endometrium is commonly associated with hormonal drugs and endometrial polyps and is characterised by papillae with fibrovascular cores covered by epithelial cells without cytologic atypia.

The menstruation phase 1rst to the 4th day distinguishes the beginning of each menstruation cycle. When an implantation does not occur, the back-formation of the yellow body corpus luteum lowers the amounts of circulating estradiol and progesterone hormones, which leads to the expulsion of the functional layer of the endometrium. The cramp-like contractions of the tunica media of the spiral arteries is responsible for an interruption of the blood supply ischemia , which results in the dying out of the functional layer of the endometrium.
Together with blood, which does not coagulate due to a local fibrinolytic factor, the necrotic tissue is eliminated menstruation.

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.

In the late secretory phase, endometrial stromal cells ESC around the blood vessels begin to differentiate into decidual cells, and AngII has been reported to accumulate around such vessels. However, whether there is a concurrent increase in renin or angiotensin-converting enzyme in this area has not been determined. Western blot analysis in the present study demonstrated that a considerable amount of APA was present in the secretory phase endometrium. The enzyme activity and the biosynthesis of [ 35 S]methionine-labeled APA significantly decreased during the in vitro decidualization of cultured ESC.
These results suggest that the perivascular disappearance of APA is a differentiation-specific change that occurs along with the decidualization, and that the disappearance of APA might accelerate the accumulation of AngII around the vessels.

Boomsma, A. Kavelaars, M. Eijkemans, E. Lentjes, B. Fauser, C. Heijnen, N. The study of human endometrial—embryonic interactions is complicated by the disruptive impact of endometrial sample collection on the process of implantation itself. Endometrial secretion analysis is a novel technique, non-disruptive to implantation. The primary aim of this prospective cohort study was to explore whether a cytokine profile predictive of implantation and clinical pregnancy can be identified in endometrial secretions aspirated immediately prior to embryo transfer following IVF.
In order to detect implantation, daily urine samples were collected after embryo transfer, and human Chorionic Gonadotropin hCG concentrations were analyzed by an immunoassay.
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.

JBRA Assist. The literature has suggested that patients with endometriosis present progestin resistance, which could affect embryo implantation. We question the presence of alterations in the expression of the progesterone receptor gene PGR and the genes related to endometrium-embryo interaction regulated by progesterone. We assessed the size of the difference that our series was powered to detect.

Subsequently, for the vast time where I was pregnant, herbally aborting and miscarrying, I spoke to only a few people. I have a regular period and charted my basal temperature for 6 months in the beginning, making me confident of my ovulation timing. If your blood type is negative your body may attack the blood of the baby, if it has inherited positive blood from the father causing Rh incompatibilityy. This can be problematic during miscarriage, abortion or birth and can harm future babies.
The digital test dated weeks, and the blood test came back as , HCG—very, very pregnant. This data is entered into a phone app which now keeps track of my cycle. At the end of last year, my boyfriend accidentally broke my phone. When I replaced my phone, it restored all the apps as usual, and I went back to charting—not realising that as those two months were now blank, the average period length and predicted date of ovulation had changed. For the first 2 days, I cried every time I talked about the pregnancy.
