Endometrial Receptivity and the ERA Biopsy

Endometrial Receptivity and the ERA Biopsy

Patients and Methods: A novel method was used for endometrial dating, with parameters including menstrual cycle days, Noyes histological criteria, along with immunohistochemical expression pattern of estrogen and progesterone receptors and proliferation marker Ki Results: Endometrial maturation varied individually, occurring 1. Comparison of histological maturation with clinical days after ovulation showed a delay of about 2 days. Conclusion: Endometrial maturation requires 8 days, rather than the expected 6 days, to reach the histological mid-secretory phase. This is not a delay and is also seen in fertile patients. The new analysis method used is superior to that using Noyes criteria alone and provides a better basis for determining conditions for optimal timing of embryo transfers. The endometrium is one of the major factors involved in embryo implantation.

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.

The present application claims priority of application Ser. The present invention relates generally to the fields of infertility, endometrial hyperplasia, assisted reproduction, and hormone replacement therapy for women, and methods of assessing and monitoring endometrial development in connection with diagnoses and therapies related to the same. Many of these couples further pursue costly procedures using assisted reproductive technology ART in an attempt to overcome their unidentified problems.

Yet, even with ART, only Also, the live birth rate decreases to Clearly, despite improvements in embryo quality and culture conditions, some women are still unable to become pregnant. Their infertility, as well as the infertility experienced by many women, is likely caused in part by implantation difficulties. Thus, predictors of implantation potential are needed, both to better understand the causes of infertility in women and to improve the efficacy and reliability of embryo transfer.

Despite over two decades of ART, no tools for endometrial evaluations exist which can adequately predict whether implantation will occur during any given ART cycle.

Estradiol stimulation results in proliferation of the basalis and functionalis, whereas progesterone promotes glandular development and secretion and is believed to initiate the changes necessary for implantation.

They were instructed to collect their first morning voided urine upon awakening each day, to label each tube with their names and the date, and to freeze the tube within 2 h of voiding. Technique was geared toward obtaining a cylinder of intact tissue; therefore, a back and forth motion was not used. Dating the endometrium histologically is customarily accomplished using standards set by Noyes 6—8 days after ovulation may provide greater detection of histological abnormalities 8 and, hence, greater sensitivity of the clinical test.

We evaluated the ability of the endometrial biopsy to detect luteal adequacy in a small population of fertile, midreproductive-aged women. To examine the relationship between endometrial histological maturation and reproductive hormones, we studied 11 fertile women, aged 18—37 yr. All participants had had at least 1 previous pregnancy and cycled regularly, every 25—35 days.

Final dating was agreed upon based upon the method of Noyes E1c and Pdg were integrated throughout the cycle using the trapezoidal rule, and correlations were sought between deviation from expected histology based upon urinary hormones and LH surge and integrated hormone values. If less than a 5-cm-long cylinder of tissue appeared to have been obtained, and the participant agreed, a second pass was made with the Pipelle to assure that adequate tissue was obtained. One third was immediately placed into formalin for fixation and histological evaluation.

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.
