[Hormone profiles and hormone therapy in early pregnancy (author's transl)]

Hormone profiles in early pregnancy were established in 67 women and correlated to simultaneously performed ultrasonic examinations. Normal values for human chorionic gonadotropin (HCG), human chorionic somatotropin (HCS), oestradiol (E2) and progesterone (P) were established from the data obtained in 30 early pregnancies which culminated in the birth of a living child. Lowered HCG values were found in 17 out of 23 pregnancies which ended in miscarriage. In these cases ultrasonic examination failed to detect any heart action. Lowered HCS values after the 9th week of pregnancy are also certain proof of missed abortion. P and E2 values are shown to be a parameter reflecting activity of the corpus luteum graviditatis. In clomiphene- and gonadotropin-induced pregnancies higher values were found than in pregnancies managed by substitution treatment with twice weekly 10 mg oestradiolvalerianate + 500mg 17alpha-hydroxyprogesteronecapronate. Lowered P and E2 values with HCG values in the normal range indicate imminent insufficiency of the corpus luteum graviditatis. Pros and cons of hormonal therapy in early pregnancy are discussed.
