Secretory phase endometrium
This study was based on our attempt to establish an outline for diagnosing endometrial dating on endometrial cytology. The study is based on a total of patients who underwent endometrial biopsy and cytology. Cell samples obtained from the uterine cavity by Endosearch were washed in physiological saline solution and then squashed between two slides for fixation and staining.
Uterine endometrial dating patterns were classified into five types: early proliferative phase, late proliferative phase, early secretory phase, mid secretory phase and late secretory phase.
For secretory phase endometrial dating, ovulation is used as the primary reference point. Originally, ovulation was assumed to occur on day 14 of.
Nevertheless, there is no consensus regarding the most suitable period of the luteal phase for performing the biopsy. OBJETIVE: This study evaluated the correlation between the histological dating of two endometrial biopsies performed in the same menstrual cycle, on luteal phase days six and ten. Dating was done according to morphometric criteria, in which an endometrium sample is considered out of phase if the minimum maturation delay is one day.
Luteal phase. Female infertility. Evaluation of the luteal phase of regularly cycling women complaining of infertility is directed towards the evaluation of corpus luteum activity and the action of progesterone on the endometrium. Endometrial maturation, whose role in human reproduction was first recognized by Jones, 1 is evaluated by the Noyes criteria.

The lining epithelium contains glycogen rich subnuclear vacuoles in the early secretary phase. The vacuoles will be supranuclear in midsecretary phase. In the late secretary phase, the glands are saw toothed and serrated with luminal secretions. This is called predecidual change as these are the precursors of decidual cells in pregnancy. The endometrium is obtained for evaluation by a process called dilatation and curettage or by endometrial biopsy.

The significance of dating an endometrial biopsy for the prognosis of the infertile couple.
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.

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. Between 7—9 days after home detection of a LH surge Sure Step , participants underwent an endometrial biopsy using a small bore Pipelle catheter. Tissue was prepared for histological and biochemical analyses. The histological analysis is reported herein.

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. Further, while reasonable consensus exists that endometrial biopsy is the most reliable diagnostic tool, concerns remain about its timing, repetition, and interpretation. It was first described by Jones in

SECRETORY PHASE. In contrast to the proliferative stage, progressive changes occur in the endometrium of the secretory phase at a rate that we believe.
The upper part of the uterus fundus is attached to the fallopian tubes while the lower part is connected to the vagina through the uterine cervix. Functions of the uterus include nurturing the baby, and holding it until the baby is mature enough for birth. The endometrium is hormone-responsive which means it changes in response to hormones released during the menstrual cycle. Following every menstrual period menses the endometrium grows to a thick, blood vessel-rich, glandular tissue layer, providing an optimal environment for a fertilized egg.
If the fertilization does not occur, the endometrium breaks down, leaving only the bottom layer basal layer and many open blood vessels. This leads to a temporary bleed and discharge of blood and endometrial tissue through the vagina menstruation, menstrual period, menstrual flow. Once the menstruation is over, the endometrium starts growing again, and the cycle repeats. During the menstrual cycle, the endometrium grows under the influence of two major hormones — estrogen and progesterone.
In the first part of the menstrual cycle, between menses and ovulation ovulation is when a mature egg is released from the ovary, pushed down the fallopian tube, and is made available to be fertilized , the endometrium grows under the influence of estrogen. This is also known as proliferative endometrium. Secretory endometrium is a normal non-cancerous change seen in the tissue that lines the inside of the uterus.
It is a normal finding in women of reproductive age. After ovulation, the endometrium grows under the influence of progesterone.

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.
We will also review pathologic states, such as endometriosis and related progesterone resistance, which affect mid-secretory phase and implantation. Finally, we will provide a detailed review of the literature on what the current state of knowledge is regarding receptivity and the microenvironment of the mid-secretory endometrium which is essential to implantation. Menstrual Cycle.
The female reproductive system prepares women for conception and pregnancy through two distinct, but highly integrated, cycles, the ovarian cycle and the endometrial cycle.

Menstruation describes the female period. The menstruation cycle begins when a woman gets her periods. The menstrual blood which leaves her body are products shed from the uterus the uterine lining also called the endometrium. During the remainder of the menstrual cycle the uterine lining regrows. It does so in preparation for pregnancy, which occurs if the egg oocyte a woman releases about half way through her menstrual cycle is fertilised. When fertilisation occurs, the lining stays in place to nourish the fertilised egg.
Women begin menstruation at an average age of 13 called menarche and on average continue menstruating till age 51 called menopause. Menstruation involves highly complex hormonal interactions. The key hormones involved in menstruation are oestrogen and progesterone produced by the ovaries and luteinising hormone and follicle stimulating produced by the pituitary gland , under the influence of hormones secreted by the hypothalamus. The interactions between these organs are referred to as the hypothalamic-pituitary-ovarian axis HPO axis.
