Abstract :Aim: This study aimed to investigate the role of beta human chorionic gonadotropin (beta hCG) levels on post embryo transfer (ET) 12th- and 14th-day, and its folding after 48 hours in predicting live birth, abortion, and biochemical pregnancy. Material and Methods: The study included 124 patients who had a positive pregnancy test after a fresh single day 3 ET at the in vitro fertilization (IVF) center between 2017 and 2021. The first beta hCG value was measured 12th day and the second 14th day after ET. The beta hCG fold was calculated by dividing the second beta hCG value by the first beta hCG value. Results: The patients\' IVF indications included unexplained (n=40, 41.1%), poor ovarian reserve (n=23, 25.0%), male factor (n=31, 29.8%), and tubal factor (n=3, 4.1%). Of the 124 patients, 97 (78.2%) had a fetal sac, 81 (63.5%) had a fetal heartbeat (FHB), and 70 (56.5%) had a live birth. The results indicated that the post-ET 14th-day beta hCG level was the best predictor of biochemical pregnancy. It has a high sensitivity (92.5%) and specificity (86.6%), with an optimal cut-off value of 175 U/L. The post-ET 14th-day beta hCG level was the best predictor of a live birth. The post-ET 14th-day beta hCG value of 214.5 U/L had an 82.7% sensitivity and 74.4% specificity to predict the FHB. Conclusion: The beta hCG value, measured between the 12th and 14th days after ET, as well as the folding rate on these two days, can provide information about the pregnancy progression.Keywords : Beta hCG, canlı doğum oranı, embriyo transferi sonrası, gebelik sonucu
