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.
Hormonal Pathology of the Endometrium
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.

8 Histologic Dating of the Normal, Cycling Endometrium 10 Proliferative Phase Endometrium 11 Secretory Phase Endometrium.
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. Progesterone therapy for endometrial hyperplasia and neoplasia induces glandular secretory changes, decidual reaction, and spiral arterioles. Glandular proliferation is usually arrested, but neoplastic changes may persist and coexist with secretory changes. Lupron therapy produces a shrinking of uterine leiomyomas by accelerating their hyaline degeneration, similar to that in postmenopausal involution.
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.

Metrics details. Chronic endometritis CE is a continuous inflammation of uterine endometrium, and it is usually symptomless. As CE has been thought not to affect the reproductive status and general health of affected women, its significance has not been explored. However, recent studies have shown that CE is related with repeated implantation failures after in vitro fertilization-embryo transfer, unexplained infertility, and recurrent miscarriages.
As decidua differentiates to support the implantation process and maintains the pregnancy, we hypothesized that CE may influence the process of decidualization. Seventeen patients were employed in the experiment involving culture of endometrial stromal cells ESCs. The concentrations in culture media and the protein expressions in ESCs of prolactin PRL and insulin-like growth factor binding protein-1 IGFBP-1 , two well known decidualization markers used in a large number of in vitro models, were analyzed by ELISA and Western blotting, respectively, and the cell numbers were also counted.
Our data suggests that CE modifies decidualization of human ESC through untuning the function of sex steroid hormone receptor.
Endometrial Dating Method Detects Individual Maturation Sequences During the Secretory Phase
Study record managers: refer to the Data Element Definitions if submitting registration or results information. Worldwide, 1 in 12 couples experience difficulty in getting pregnant and seek the help of assisted reproductive technologies ART such as in vitro fertilization IVF-egg is fertilized by sperm outside the body , ovarian stimulation medications are used to stimulate egg development and intra-cytoplasmic injection ICSI-single sperm is injected directly into the egg.
Regardless of the ART procedure being performed, the newly fertilized embryo must still implant into the mothers endometrium inner lining of uterus. Intrauterine infusion of hCG prior to embryo transfer has recently been shown to increase pregnancy rates but the cellular mechanism for this increase is unknown. Successful implantation requires the newly fertilized embryo and the endometrium develop in a synchronized manner.
This coordinated development is accomplished, in part, by proteins secreted by the embryo which circulate throughout the maternal bloodstream and alert the maternal body organs i.
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.
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. In atypical hyperplasia, the nuclear changes are often accompanied by proliferative changes, such that the types have more endometrium, often eosinophilic, cytoplasm. Secretory changes, including disordered cytoplasmic eosinophilia, may also be seen in various endometrial metaplasias, endometrium as ciliated metaplasia.
Nuclear features in atypical hyperplasia, which, as stated earlier, are often subtle, include nuclear stratification, loss of polarity, nuclear rounding and the presence of nucleoli.
The significance of dating an endometrial biopsy for the prognosis of the infertile couple.
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.
Uterine endometrial dating patterns were classified into five types: early proliferative phase, late proliferative phase, early secretory phase, mid secretory phase.
Everyone would agree that functionality of the uterine lining is incredibly important for implantation of the blastocyst to take place. The methods that have been used in the past were indirect, assumptive and not reproducible. Researchers in Spain have created a new tool which has been shown to be promising for identifying molecular markers for uterine receptivity. Remarkably, as the blastocyst floats within the uterine cavity looking for a place to land, a dialog takes place between the blastocyst and the endometrium.
The hormonal preparation of the uterus plays a critical role each month in creating this environment in which the blastocyst can adhere to the endometrium in the hope that implantation will take place. The uterine lining undergoes changes during the two phases of the menstrual cycle that prepare it for blastocyst implantation. During the proliferative phase, it grows due to the increasing production of estrogen by the ovaries.
The second phase is called the secretory phase where the production of progesterone, produced by the corpus luteum, converts the endometrial lining to a secretory one, changing the cells to prepare for implantation a process called decidualization. Should implantation not take place, the hormone levels will fall, resulting in a shedding of the lining, which results in menses.
Studying the mid-secretory phase is of great importance since the window of implantation WOI takes place then. The sweet spot of WOI is approximately a 2-day period when the uterus is prepared to accept the implantation of a blastocyst. Conventionally, it was assumed that every woman had the same WIO, approximately days after ovulation so embryo transfers would be scheduled to take place during this time.
Secretory Phase and Implantation
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.

Published online January 1, Endometrial pattern and thickness were observed in those patients receiving infertility work up from April, 1 f94 to July, at Seoul National University Hospital. The study group was patients with normal regular menstrual cycles. Among them, 44 patients received endometrial biopsy, and the date of endometrium was compared with the observed endometrial pattern and thickness. The observed endometrial pattern was presence or absence of central cavity echogenicity, triple line sign, endometrial hypoechogenicity, ring sign, endometrial hyperechogenicity and posterior acoustic sonic enhancement.
The results were as follows; Central cavity echogenicity was seen throughout menstrual cycle. Triple line sign was observed in However, in mid to late secretory phase, triple line sign was appeared in only 6. The percentage of positive endometrial hypoechogenicity was highest in early secretory phase. In contrast to hypoechogenicity, positive endometrial hyperechogenicty was highest in mid to late secretory phase.
