Dating Endometrial Biopsy
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.
An endometrial biopsy was obtained on the seventh or eighth dating was also assessed in tissues according to criteria of Noyes et al.
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.

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.

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. This study evaluated the correlation between the histological dating of two endometrial samples, obtained by biopsies performed on luteal phase days 6 and 10 of the same menstrual cycle.
Twenty five regularly cycling healthy women, complaining of infertility for at least one year, voluntarily agreed to participate in the study group and gave their informed written consent. Blood samples were drawn from patients between days one and five of the menstrual cycle, for basal plasma levels of LH, FSH and prolactin, measured by immunofluorimetry normal ranges: FSH: 2.
A transvaginal ultrasonograph was also done to evaluate uterine echoes. From menstrual cycle day nine onwards, follicular diameter 7 and endometrial thickness 8 were measured daily by transvaginal ultrasound. When the dominant follicle reached at least 16 mm, daily plasma LH level measurements were started, until an LH peak was demonstrated.

When disparity was observed between glands and stroma, each component was dated separately, and the overall histological date was taken as the mean. 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.

While the dose of progesterone administered consistently resulted in an increase of salivary progesterone concentration to above the upper limit of the reference range, no significant effect on endometrial development was observed; in particular, endometrial development was not advanced.
