title: Doubling time of urine human chorionic gonadotropin after assisted reproductive technology.
abstract: In the present study, we measured urinary hCG after assisted reproductive technology to accurately calculate normal doubling time (DT) of hCG, and we compared DT values with prognosis of pregnancy. We clarified the correlation between normal DT values, calculated from urinary hCG levels, and viable and nonviable pregnancies.
