Highly specific and sensitive rise in Days 14–17 pro-αC inhibin with clinical pregnancy after frozen embryo transfer with ovulatory cycles

Abstract

Clinical pregnancy is always associated with a release of luteal derived pro-alphaC 14-17 days after conception. Pro-alphaC may play a possible biological role and be a useful clinical biomarker of luteal health.

Serum HCG measured in the peri-implantation period predicts IVF cycle outcomes

“…The initial detection of HCG in urine or serum is a common indicator of pregnancy and serial measurement of HCG concentration is commonly used to differentiate normally progressing pregnancies from ectopic pregnancies or spontaneous abortions. Following cycles of IVF and embryo transfer, it is routine to confirm early pregnancy through measurement of serum concentration of HCG 10-12 days after blastocyst transfer or 12-14 days after cleavage-stage embryo transfer (Bjercke et al, 1999;Poikkeus et al, 2002), although other molecules have been tried for this purpose (Tong et al, 2007).…”
