Figure 1 Diagnostic outcomes of pregnancies of unknown location from fresh and frozen IVF cycles using autologous oocytes. Pregnancy of unknown location defined as a positive serum β-hCG without evidence of extrauterine or intrauterine pregnancy on transvaginal ultrasound. Abnormal β-hCG trend defined as an increase <53% or a decrease <15% in 2 days. Early failed intrauterine pregnancy diagnosed by β-hCG decline ≥15% after sampling (“adequate β-hCG decline,” n = 30) and/or villi on final pathologic diagnosis (“Villi,” n = 21). Presumed ectopic pregnancies (EP) met neither criterion.
