title: Measurement of endometrial volume increase during the first week after embryo transfer by three-dimensional ultrasound to detect pregnancy: a preliminary study.
abstract: Endometrial volume and thickness were measured in 20 women undergoing in vitro fertilization on the day before the embryo transfer and one week later by three-dimensional ultrasound. The endometrial volume increase was higher in the 8 pregnant women (0.70 cm(3) at least) than in the 12 nonpregnant women (0.21 cm(3) at most).
