Abstract
Progesterone rose significantly from days 35 today 60 Pregnenolone likewise rose significantly from days 35–60 but at a much higher rate with an increase of 57 by day 60 75 to day 80 The increase in pregnenolone was statistically more significant than the increase in progesterone p 05This is the first report describing that progesterone’s precursor pregnenolone increases with time in the very early pregnancy Because no corpus luteum is present in oocyte recipients the main source of pregnenolone is the early placenta Measurements of pregnenolone may provide information concerning early trophoblast function and may represent a method of assessing placental competency
