Serum β-hCG, AMH, TSH, and PRL Levels in Predicting the Outcome of Early Pregnancy 14 Days after Embryo Transfer: A Prospective Cohort Study.

BACKGROUND

Pregnancy outcomes in assisted reproductive technology (ART) are influenced by the ability of the embryos to create a pregnancy and maternal factors such as hormone levels to maintain and develop the pregnancy. This study investigated the role of β-human chorionic gonadotropin (β-hCG), anti-mullerian hormone (AMH), thyroid-stimulating hormone (TSH), and prolactin (PRL) in predicting pregnancy outcomes and determined cutoff values in women undergoing ARTs.

MATERIALS AND

METHODS

This prospective study included 153 women who underwent infertility treatment in the Department of Reproductive Medicine of the Yas Hospital, Tehran University of Medical Sciences (Tehran, Iran). Serum β-hCG level on day 14 after embryo transfer and serum AMH, TSH, and PRL were measured. Patients with β-hCG levels >25 mIU/ml were included in the study. Finally, any statistically significant relationships between these serum values and clinical pregnancy and live birth rate were investigated. To predict pregnancy outcomes with β-hCG levels, a receiver operating characteristic curve was used to estimate the β-hCG cutoff values.

RESULTS

Serum β-hCG levels were significantly higher in live-birth patients than in other patients. The β-hCG cutoff value for live births was 830 mIU/ml, with an AUC of 0.5920, sensitivity of 61.04%, and specificity of 56.58%. Serum AMH, TSH, and PRL levels did not show any significant results.

CONCLUSIONS

Serum β-hCG levels on day 14 after embryo transfer can be used to predict the probability of live birth in patients undergoing infertility treatment.
