Secretory endometrium dating comox valley dating
When accurately performed, endometrial dating provides valuable information.
A total of 172 patients who underwent hysteroscopic assessment of the endometrium and then became pregnant, was analysed retrospectively to explore the relationship between endoscopic findings and early phase pregnancy outcome after implantation.
At diagnosis of pregnancy, the mean age of the patients was 34.8 ± 3.8 (range 25–44) years.
These authors demonstrated that the assessments of the mid-secretory endometrium could be classified as `good', characterized by ring-type glandular openings showing maximum glandular secretion and well-developed varicose-like vessels, or `poor', characterized by dot- (no secretory) and/or punctate-type (early secretory activity) glandular openings and fine vasculature and that, in IVF and embryo transfer cycles, the pregnancy rate was significantly higher in patients with `good' hysteroscopic findings than in patients with `poor' findings.
In this context, it was felt to be of interest whether or not the hysteroscopic appearance of the endometrium is associated with early pregnancy loss as well as with implantation failure of fertilized ovum.
Hysteroscopy is not yet used routinely to observe the morphological condition of the endometrium, although it has been employed in studying endometrial pathologies which might cause female infertility (De Jong ., 1996).
Previous studies have shown that hysteroscopic observations could provide useful morphological information to evaluate the functional state of the endometrium, based on serial phase-specific changes in appearance of glandular openings and vasculature on the endometrial surface in subjects with normal ovulatory cycles (Inafuku, 1992; Sakumoto ., 1992).

Histological examination of the endometrium and assay of serum progesterone and oestrogen were carried out simultaneously with hysteroscopy. Of the remaining 160 patients, 62 (38.8%) were classified endoscopically as having `good' mid-secretory endometrium and 98 (61.3%) as `poor', between one and four cycles prior to the conception cycle.
