Reports have suggested a correlation between low serum progesterone (P) levels prior to human chorionic gonadotropin (hCG) administration and increased pregnancy rates in patients undergoing in vitro fertilization (IVF) patients. We have published two opposite conclusions, dependent upon the methodology used. Pregnancy rates were higher when P by radioimmunoassay (RIA) was < 1 ng/mL, but no increase in pregnancy rates were found when P was measured by the same company's non-isotopic assay.
