title: Sonography of the endometrium during conception and nonconception cycles of in vitro fertilization and embryo transfer.
abstract: The thickness of the endometrium was compared in 15 patients who conceived and 15 who did not with an in vitro fertilization and embryo transfer (IVF-ET) protocol after ovulation induction with human menopausal gonadotropin/human chorionic gonadotropin (hMG/hCG). There was no statistically significant difference (P = 1.0) in the endometrial thickness in the conception versus the nonconception group. Average estradiol (E2) values and number of mature follicles were also not statistically different in the two groups (P = 0.78, P = 0.81). There was a slightly significant difference in the number of embryos transferred in the conception versus nonconception groups (2.5 versus 1.9, P = 0.005). However, the most significant difference between the conception and nonconception groups was the total number of oocytes retrieved (4.4 versus 2.8, P = 0.005). These findings indicate that there are no sonographically detectable differences in the endometrial thickness in patients who achieve pregnancy versus those that do not when given a similar ovulation induction regimen of hMG/hCG for IVF-ET.
