An hCG level under 5 is considered negative. For patients with a regular menstruation cycle, the natural cycle was the first choice and blastocysts were transferred 5days post-ovulation. Higher -hCG levels are indicative of better pregnancy outcomes including higher rates of clinical pregnancy and live births [9]. One hundred eleven patients had positive serum quantitative hCG levels 14 days post-ET; 89/111, or 80.2%, had ongoing pregnancies. For that reason the data was analysed through a multinomial logistic model vs. multinomial distribution of a mistake and generalised logistic link function. Although prior work has attempted to predict pregnancy outcomes by assaying serum -hCG levels after blastocyst transfer, no study has focused on pregnancy outcomes in those with initially low serum -hCG levels.
