Correspondence and reprint requests: Dr. Aboubakr M. El Nashar, Althawra St. Embryo implantation depends on the quality of the ovum and endometrial receptivity. Endometrial receptivity is a temporally unique sequence of factors that make the endometrium receptive to embryonic implantation. Implantation window is a period during which the endometrium is optimally receptive to implanting blastocyst D postovulation. No conclusive evidence of age related histological changes in the endometrium. The biochemical markers of endometrial receptivity include endometrial adhesion molecules e.

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.

secretory endometrium meaning.

During this part of the menstrual cycle, the endometrial glands are lined by columnar epithelium with nuclear pseudostratification, dense chromatin, and variably present small nucleoli. Early proliferative endometrium days 4 to 7 of the menstrual cycle is characterized by thin surface endometrial epithelium and sparse, narrow, straight endometrial glands lined by cells with mild pseudostratification of the nuclei.

There are a few mitoses in the epithelium and in the stroma e-Fig. In the midproliferative phase days 8 to 10 of the menstrual cycle , the glands are slightly tortuous and the surface epithelium is columnar; the stroma is edematous and mitoses are present in both the epithelium and the stroma Fig. Mitoses in the epithelium and the stroma become more abundant.

The stromal edema disappears Fig. The term interval endometrium refers to the endometrium during the first 36 hours after ovulation.

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.

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.

The recurrent miscarriage group showed reduced levels of four mucin-related secretory epitopes, and greater nological dating of the endometrium has been.

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. This leads to a temporary bleed and discharge of blood and endometrial tissue through the vagina menstruation, menstrual period, menstrual flow.

Endometrial cancer is a cancer that arises from the endometrium the lining of the uterus or womb. The leading treatment option for endometrial cancer is abdominal hysterectomy the total removal by surgery of the uterus , together with removal of the Fallopian tubes and ovaries on both sides, called a bilateral salpingo-oophorectomy. Symptoms other than bleeding are not common.

Other symptoms include thin white or clear vaginal discharge in postmenopausal women.

Uterine endometrial dating patterns were classified into five types: early proliferative phase, late proliferative phase, early secretory phase, mid secretory 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.

Chapter 8 Pathology of Reproductive Endocrine Disorders. An appreciation of the relationship between form and function is important for understanding of female reproduction. An awareness of histologic changes associated with both the normal ovulatory cycle and reproductive diseases allows the physician a better understanding of pathophysiology and potential treatment. This chapter begins with an examination of the histologic changes in the endometrium associated with a normal ovulatory cycle.

This study was based on our attempt to establish an outline for diagnosing endometrial dating on endometrial cytology. The study is based on a total of patients who underwent endometrial biopsy and cytology. Cell samples obtained from the uterine cavity by Endosearch were washed in physiological saline solution and then squashed between two slides for fixation and staining. Uterine endometrial dating patterns were classified into five types: early proliferative phase, late proliferative phase, early secretory phase, mid secretory phase and late secretory phase.

Cytological criteria for diagnosing endometrial dating approximate the relationship of useful morphological factors by endometrial biopsy Gland mitoses, Pseudostratification of nuclei, Basal vacuolation, Secretion, Stromal edema, Pseudodecidual reaction, Stromal mitoses, Leucocytic infiltration, Gland tortuosity and Spiral arterioles.

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 ]. Embryo implantation is a crucial event in the establishment of a pregnancy. It is now clear that embryo implantation relies upon cross-talk and synchronicity between the implanting embryo and a receptive endometrium [ 3 ].

Clinical Question 3 If the endometrium is secretory, is it appropriately developed for the patient’s chronologic dates (see “Endometrial Dating”)? The only.

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. Endometrial maturation, whose role in human reproduction was first recognized by Jones, 1 is evaluated by the Noyes criteria. This study evaluated the correlation between the histological dating of two endometrial samples, obtained by biopsies performed on luteal phase days 6 and 10 of the same menstrual cycle.

Twenty five regularly cycling healthy women, complaining of infertility for at least one year, voluntarily agreed to participate in the study group and gave their informed written consent. Blood samples were drawn from patients between days one and five of the menstrual cycle, for basal plasma levels of LH, FSH and prolactin, measured by immunofluorimetry normal ranges: FSH: 2. A transvaginal ultrasonograph was also done to evaluate uterine echoes. From menstrual cycle day nine onwards, follicular diameter 7 and endometrial thickness 8 were measured daily by transvaginal ultrasound.

When the dominant follicle reached at least 16 mm, daily plasma LH level measurements were started, until an LH peak was demonstrated.
