Predictive Value of Serum beta-hCG Level in Pregnancies following In Vitro Fertilization and Embryo Transfer
Abstract
- Serum level of beta-subunit of human chorionic gonadotropin (beta-hCG) at the post-ET day 16 was studied to evaluate its predictability of pregnancy outcome in 165 patients in vitro fertilization and embryo transfer (IVF-ET), which included 63 singleton pregnancies, 40 multiple pregnancies, 37 preclinical abortions, 20 clinical abortions and 5 ectopic pregnancies. In comparison to normal singleton pregnancies, multiple pregnancies showed significantly higher serum beta-hCG level and preclinical abortions showed significantly lower serum beta-hCG level, but Clinical abortions and ectopic pregnancies didn`t showed statistical significance level of serum beta-hCG. In conclusion, determination of serum beta-hCG level at post-ET day 16 is a useful tool for the prediction of preclinical abortions and multiple pregnancies.
