P-54: Predictability of pregnancy viability after assisted reproductive techniques (ART) cycles by CA-125 and progesterone serum levels on the day of β-hCG testing

Abstract

Ideally a marker of ART success should predict treatment outcome as early as possible. Serum progesterone levels have been found to be defective before an adverse pregnancy outcome. CA-125 is found in endometrial tissue and glands, although it may have an ovarian origin too. Higher levels in conception vs non conception ART cycles have been found, rising the question about a possible serum marker of endometrial receptivity. The objective of this study is to evaluate the prognostic value of pregnancy outcome of serum CA-125 and progesterone levels in ART cycles testing positive for β-hCG, with a fixed progesterone supplementation protocol.
