Although most board-certified reproductive endocrinologists agree on the major areas of the performance of infertility testing, there was significant variability in the details of the performance of most testing, especially with respect to physician age and geographic location. Biopsies can only provide a snapshot of the real situation in the endometrium, and sample bias is unavoidable because it is not applicable to take large numbers of samples. However, despite these advances, pregnancy rates are still relatively low and have not increased significantly in the last decade ;. These incidences in normal, fertile women are as high as the rates quoted for infertile populations, and call into question the standard criteria for defining this condition and evaluating therapies to correct it. In routine dating, the pathologist should avoid bias by evaluating the histologic section before reading the clinical information. Endometrial biopsy was the adequacy of noyes et al. Our findings indicate that an endometrial biopsy performed in the midluteal phase may detect a greater number of women with delayed endometrial maturation during the temporal window of embryo implantation. A single, well-timed progesterone determination appeared adequately to reflect the data obtained from serial samples in the same cycle. There also seem to be abnormalities associated with intracellular deposits of glycogen-rich material and mitochondrial elaboration in the infertile women. Contrib Embryol ,
hundred-and-twenty-five endometrial biopsies were taken within 4 according to Noyes et al. Traditional dating criteria of a late luteal phase endometrial.
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.
Schematic representation of steroid hormone-morphologic interactions during the endometrial cycle. Estradiol promotes endometrial proliferation, whereas after ovulation, progesterone converts estradiol-primed endometrium into secretory tissue. Postovulatory estradiol amplifies the progesterone effect, and after withdrawal of both estradiol and progesterone, the endometrial mucosa breaks down and regenerates within the period of menstruation.
Steroid hormone control of endometrial, epithelial, stromal, and presumably endothelial cells is mediated by estrogen receptors and progesterone receptors. These steroid receptors are specific proteins concentrated exclusively in the nuclei of both endometrial epithelial and stromal cells, as well as the endothelial cells of stromal capillaries.
They have high affinity to bind estradiol and progesterone, respectively. This chapter contains a review of the technical procedures for handling endometrial tissues and a discussion of the morphologic aspects of the endometrium, focusing on the interpretation and understanding of the physiomorphology of the endometrial cycle.
In current practice, the device that is most often used is the Pipelle endometrial aspirator.
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.

LPD results from low endogenous progesterone production and the resultant insufficiency to maintain a secretory endometrium to allow embryo implantation and growth [ 2 ].
Jones studied the luteal phase by evaluating basal body temperature charts, urinary pregnanediol excretion hour urine collection at the peak of luteal phase by basal body temperature , cervical mucus, and most importantly, timed endometrial biopsies. In the initial study, Jones evaluated cycles in 98 women with infertility that was not due to tubal, uterine, anovulation or male factor.

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.
In the most common terminology for dating the endometrial biopsy, day 1 is used as the To circumvent the limitations of the Noyes et al histology criteria, it is.
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.
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. This will be put in the context of the luteal phase of ovulation and the hormonal support that progesterone provides.
