In women at risk for an ectopic pregnancy, every effort should be made to exclude the presence of an intrauterine pregnancy before embarking on an irreversible treatment for ectopic pregnancy. The diagnosis of ectopic pregnancy, unless directly visualized with transvaginal ultrasound, is made with the exclusion of an intrauterine pregnancy. Measurement of human chorionic gonadotrophin and progesterone levels, and transvaginal ultrasound are the tools used to evaluate early pregnancy. In women at risk for an ectopic pregnancy, every effort should be made to exclude the presence of an intrauterine pregnancy before embarking on an irreversible treatment course. Methotrexate is an antimetabolite that inhibits DNA synthesis and repair and cell replication. It is administered to ostensible destroy a pregnancy, especially ectopic pregnancies. When administered to an intrauterine pregnancy, embryonic death and missed abortion is the most common result, but early embryos that survive this exposure are likely to have multiple anomalies. The mistaken administration of methotrexate to an intrauterine pregnancy is made because of misinterpretation of the discriminatory zone of human chorionic gonadotropin hCG , misinterpretation of early hCG serum levels, misinterpretation of early transvaginal ultrasound images, and failure to clinically correlate hCG levels and ultrasound findings. Core tip: In women at risk for an ectopic pregnancy, every effort should be made to exclude the presence of an intrauterine pregnancy before embarking on an irreversible treatment course. In women at risk for an ectopic pregnancy, every effort should be made to exclude the presence of an intrauterine pregnancy before embarking on an irreversible treatment for ectopic pregnancy, such as the administration of methotrexate.

When the cow is in oestrus, the endometrium becomes oedematous and therefore the endometrial folds become more prominent. The lumen also has a varying.

Progesterone is the major secretory product of the corpus luteum CL. Deficiency in either the duration or the amount of progestin secretion leads to an impairment of the endometrial development and its ability to support pregnancy. Progesterone and its synthetic analogues progestins are being widely used to restore the normalcy of the endometrium in a variety of clinical conditions including CL defects, habitual and threatened abortions, endometrial hyperplasias, and certain forms of endometrial cancers [Chez, R.

They are also employed as contraceptive agents in a variety of delivery systems [Landgren, B. In spite of such widespread use of progestins, very little is known about their biochemical effects on the human endometrium and the mechanisms by which these effects are produced. Moreover, the art lacks reliable means of monitoring the responses of endometrium in individual patients to endogenous or exogenous progestins. Progesterone has been shown to bring about the differentiation of estrogen-dominated proliferative phase tissue into a secretory phase tissue.

Continued stimulation of this target tissue with progesterone, as occurring in early pregnancy, promotes decidualization of the endometrial stromal cells and induces a hyper-secretory response within the glands. Studies on the mechanism of progestin action which have been conducted on animal models have clearly shown that progesterone, like many other steroid hormones, induces specific changes in the transcription and translation of the genetic messages encoded in the cellular DNA of the target cells [Glasser, S.

Fuchs and Klopper, A. Harper and Row, New York , pp. Specific progestin-dependent translation products such as uteroglobin, purple protein and an acidic protein, and a pregnancy-specific protein have been detected in the reproductive tract of laboratory animals by other investigators. However, such proteins are species-specific, and hence, of limited clinical utility.

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.

Study record managers: refer to the Data Element Definitions if submitting registration or results information. This study will evaluate the utility of the endometrial biopsy as a tool for the routine evaluation of the luteal phase of women presenting for infertility evaluation. The study will establish whether the mid-luteal or late-luteal phase is the most appropriate time to perform an endometrial biopsy.

The study will be conducted through the multi-center Reproductive Medicine Network. Women with a history of infertility will be age matched to fertile women controls. Women will be randomized either to the mid-luteal phase 7 to 8 days post-ovulation endometrial biopsy group or to the late-luteal phase 12 to 13 days post-ovulation endometrial biopsy group. Endometrial specimens will be evaluated histologically by a “blinded” pathologist.

There is some debate about “how thin is too thin”, as well as to “how thick is too thick”. What If the Endometrium Becomes too Thick? The condition in which endometrial thickness exceeds the normal thickness is referred to as endometrium hyperplasia.

First trimester scanning is useful to identify abnormalities in the early development of a pregnancy, including miscarriage and ectopic pregnancy, and provides the most accurate dating of a pregnancy. Technique First trimester scanning can be performed using either an abdominal approach or a vaginal approach. Abdominal scanning is performed with a full maternal bladder, provides a wider field of view, and provides the greatest depth of view. Vaginal scanning is best performed with the bladder empty, gives a much greater resolution with greater crispness of fine detail.

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:.

Statistical analysis was performed using the Graph-Pad Prism software (version , Among the 32 samples collected, 17 samples had endometrial dating.

Abstract Endometrial sampling is a major component of gynecologic care as practitioners endeavor to identify the causes of abnormal uterine bleeding AUB , potential explanations for infertility, and abnormalities that might place the patient at greater risk for malignancy. The plethora of patterns that might be encountered during reproductive life and postmenopause can be confusing, and an informed pathologist is critical to optimal care. Fundamental to this task is a thorough understanding of and a systematic approach to non-neoplastic endometrial disorders.

This chapter brings together detailed descriptions of the entities encountered when evaluating uterine bleeding and an authoritative clinical perspective. The goal is to provide the reader a road map of benign endometrial disorders from both a pathologic and clinical perspective, and provide the foundation needed to address both benign and neoplastic endometrium. The majority of endometrial biopsies are performed for abnormal uterine bleeding AUB and questions that are posed in each situation requiring biopsy and the clinical information required vary for each individual case Table

Pathology of the Female Genital Tract pp Cite as. Endometrium, the lining mucosa of the uterus, is a labile tissue hormonally responsive to sex steroids elaborated in the ovary. In the first half of the menstrual cycle all its elements undergo proliferation under the influence of estrogens, and in the latter half, it responds to progesterone by the production of secretions and stromal alterations necessary for implantation of a fertilized ovum.

The factors in the hypothalamus and anterior lobe of the pituitary gland that control and regulate hormone production in the ovary are discussed in Chapter Unable to display preview.
