Endometrial Dating Method Detects Individual Maturation Sequences During the Secretory Phase

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.

The second phase is called the secretory phase where the and some recent studies that found this morphological dating method to have.

Abstract H19 is an imprinted maternally expressed gene, which is not translated to protein and functions as an RNA molecule. It is closely related to the oppositely imprinted paternally expressed insulin-like growth factor 2 IGF While the biological function of H19 is not understood, IGF-2 is a growth factor that plays a role in human follicular and endometrial differentiation.

We examined the expression of H19 in the endometrium and ovary during the menstrual cycle by in situ hybridization applied to paraffin sections of human endometrium and ovaries at different stages of differentiation.

Dating the endometrial biopsy.

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.

progesterone exposure to maintain a regular secretory endometrium the temporal responses to progesterone, that is, endometrial dating.

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. In premenopausal patients, there is significant variation at different stages of the menstrual cycle. Please note that these measurements are a guide only, as endometrial thickness may be variable from individual to individual.

The postmenopausal endometrial thickness is typically less than 5 mm in a postmenopausal woman, but different thickness cut-offs for further evaluation have been suggested. If a woman is not experiencing bleeding, and the endometrium is thickened, the guidelines are less clear. Either a repeat transvaginal ultrasound or a referral to a gynecologist is reasonable. Endometrial thickness is well assessed on MRI. Measurement should be taken at a mid-sagittal slice, similar to the ultrasound assessment plane.

Secretory phase endometrium

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.

The endometrium has a relatively constant morphology during the proliferative phase and accurate dating is not possible. • Following ovulation the secretory.

Normal Endometrium and Infertility Evaluation

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.

In the endometrium, H19 expression was confined to the stroma and fluctuated with endometrial dating to reach its peak in the late secretory stage. IGF-2 was.

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.

The significance of dating an endometrial biopsy for the prognosis of the infertile couple.

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.

During secretory phase, endometrium becomes receptive for a short period of time Histological dating of each sample was performed [17].
