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.

Normal Endometrium and Infertility Evaluation

Synchronous development of the endometrium to achieve a receptive state and of the embryo is essential for successful implantation and ongoing pregnancy. Endometrial receptivity exists only for a finite time in a menstrual cycle and the endometrium is refractory to embryo implantation outside of this window. Administration of hormones to stimulate multifollicular development within the ovary, integral to the majority of assisted reproduction ART protocols, dramatically alters the hormonal milieu to which the endometrium is exposed versus normal menstrual cycles.

More specifically, it consists of developing a specific expression microarray of endometrial receptivity Endometrial Receptivity Array or ERA which allows evaluating the receptive state of a human endometrium, as well as assessing said state for diagnostic and therapeutic purposes. Prior Art The endometrium is the mucosa coating the inside of the uterine cavity. Its function is to house the embryo, allowing its implantation and favoring the development of the placenta.

This process requires a receptive endometrium capable of responding to the signals of the blastocyst, which is the stage of development of the embryo when it implants. Human endometrium is a tissue cyclically regulated by hormones, the hormones preparing it to reach said receptivity state are estradiol, which induces cell proliferation, and progesterone which is involved in differentiation, causing a large number of changes in the gene expression profile of the endometrium, which reaches a receptive phenotype for a short time period referred to as “window of implantation”.

Though there is no consensus as to the implantation period in humans, clinical studies suggest that this process takes place between days 20 and 24 of a normal ovulation cycle Wilcox et al. The evolution of our knowledge about the human endometrium contrasts with the lack of progress in developing new diagnostic methods for the dating and study thereof. The endometrium is still evaluated today by means of histological studies based on in observations described over 50 years ago Noyes et al.

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.
