Endometrial dating noyes
To test the validity of the dating criteria, change in basal body temperature was used to correlate endometrial dating with ovulation rather than onset of menstruation.Of the 40 patients who had adequate temperature records, 31 (78%) ovulated as predicted allowing a or- 1 day error, indicating that dating is a better gauge of duration of progesterone effect than predictor of onset of menses.However, further analysis showed that biopsy does not interfere with length of flow or succeeding menstrual rhythm.You may now see our list and photos of women who are in your area and meet your preferences.Attention to qualitative changes in 8 morphological factors is most useful in dating the endometrial biopsy.During the 1st week of luteal activity, attention should be focused on changes occurring in gland epithelium: gland mitosis, pseudostratification of nuclei, basal vacuolation, and secretion.Subjects in this group will be treated with personalized frozen-thawed embryo transfer.The blastocysts were delayed or advanced transferred after ovulation depending on the endometrium dating in RIF group Exclusion Criteria: 1.
This ovarian steroid-dependant phenomenon can only take place during the window of implantation, a self-limited period of endometrial receptivity spanning between days 20 and 24 of the menstrual cycle.To determine whether biopsy caused early menstruation, the secretory phases of the 25 patients who had recorded temperatures in at least 2 cycles in addition to that in which the biopsy was taken were examined.The secretory phase was definitely shorter in the biopsied than control cycle, suggesting that biopsy does accelerate the onset of flow.These critera were used in 300 sterility biopsies taken from normally menstruating women over a 3-year period.
Absence of organic endometrial disease and availability of accurate menstrual history were the only selection criteria. 42 of the 300 patients (14%) menstruated on the day predicted, 36 (12%) menstruated later, and 222 (74%) menstruated earlier.
The clinical value of the endometrial histological dating in RIF patients in natural cycle is still to be answered.
