In 53 patients of an in vitro fertilization (IVF) program with unsucce
ssful fertilization of oocytes, an endometrial biopsy was carried out
on the day of the intended embryo transfer, The results were compared
with the thickness (assessed on the very same day by means of ultrason
ography) and the echo pattern of the endometrium, which was classified
into four grades (A to D), We found grade A in 16 cases (30%), grade
B in 22 cases (41.5%) and grade C in 15 cases (28.5%); no endometrium
was assessed as grade D, The distribution of histologic findings was n
ot significantly skewed within the respective grading categories (only
37.5% of grade A endometria, 63.5% of grade B endometria and 66.5% of
grade C endometria were in phase with the menses), The in-phase and o
ut-of-phase endometria did not display significant differences in endo
metrial thickness (8.8 +/- 0.29 mm vs, 9.13 +/- 0.4 mm), Neither the s
onographically measured endometrial thickness nor the echo pattern cor
related with the histologic findings, suggesting that ultrasonography
is inadequate for drawing reliable conclusions about endometrial recep
tivity in an IVF program. (C) 1997 World Federation for Ultrasound in
