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.

Does Luteal Phase Deficiency Exist and What is its Association with Infertility?

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.

Endometrial maturation may be profoundly affected by this altered endocrine environment. Compare endometrial histology in fertile women, fertile women undergoing hormonal stimulation for oocyte donation and infertile women undergoing fresh embryo transfers in an ART cycle with further comparisons between women who did or did not become pregnant.

Examine the presence of leukocytes and markers of endometrial maturation. Endometrial histology was examined by hematoxylin and eosin staining with a semi quantitative scoring method developed to compare histological appearance of tissues. The presence of leukocytes and developmental markers was examined by immunohistochemistry and scored. Endometrial histology was dramatically altered upon stimulation for ART.

For the purposes of this study, histologic dating of the samples according to the criteria of Noyes et al1 was undertaken on 2 separate occasions (Table I).

We aim to bring about a change in modern scholarly communications through the effective use of editorial and publishing polices. Monique Monard. E-mail : bhuvaneswari. Courtney Marsh. Katelyn Schumacher. Warren Nothnick. The female reproductive system prepares the female body for conception and pregnancy through two distinct cycles, the ovarian cycle and the endometrial cycle.

The human endometrium, under the influence of complex biological signals, undergoes cyclic changes in preparation for implantation and the initiation of pregnancy. An array of molecular activity, still poorly understood, gives rise to relatively consistent morphologic changes of the endometrium during each cycle. In an era of assisted reproductive technologies ART , there exists an ever-increasing demand to delineate these pathways in order to improve pregnancy rates.

Nanette Santoro, Laura T. 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. Women collected daily, first morning voided urine for measurement of estradiol and progesterone metabolite excretion, estrone conjugates E1c , and pregnanediol glucuronide Pdg , respectively, throughout the cycle of study.

Hormones were normalized for creatinine.

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.

Normal Endometrium and Infertility Evaluation

Implantation occurs during a specific period of the menstrual cycle, known as the window of implantation between day 6 and day 10 of the cycle, following the luteinizing hormone surge , and is dependent on a synchronized dialogue between the embryo and endometrium. This dialogue is mediated by specific biochemical factors, including hormones, growth factors, enzymes, integrins and cytokines 1 — 3. Leukemia inhibitory factor LIF , which is a multifunctional protein that belongs to the interleukin 6 cytokine family, exerts numerous regulatory actions on various domains of cellular function 4.

LIF was initially reported to induce macrophage differentiation in M1 murine myeloid leukemic cells, and to suppress their proliferation in vitro 5. LIF was later examined in transgenic mice, and was identified as the first necessary cytokine for implantation 6 , 7.
