Increased Vitamin D Levels Decrease Odds of Early Pregnancy Loss Following Intrauterine Insemination

Abstract

was 121.7 mIU/mL (IQR 86.0, 115.5), in those 35 -40 the median hCG level was 110.2 mIU/mL (IQR 75.8, 155.8), and in those > 40 the median hCG level was 119.8 mIU/mL (IQR 78.2, 173.8) at mean of 13.4 days AOR.CONCLUSIONS: Specific rises in early hCG levels after SET were associated with LB when hCG levels were checked 15 days AOR. In cycles where hCG levels both doubled and reached 100 mIU/mL by 15 days AOR, the LB rate was 84% and this was a stronger predictor of LB than either parameter alone. LB was only achieved in 9% of cycles where hCG levels neither ''doubled'' nor ''reached 100''. Age was not associated with early hCG levels in cycles that ended in LB.IMPACT STATEMENT: Defining explicit parameters related to early hCG levels that can reliably predict LB can improve counseling. Using ''doubling'' and ''reaching 100'' 15 days AOR as parameters may help guide patient's expectations regarding pregnancy outcomes as early as possible after SET.
