title: Relaxin and human chorionic gonadotropin concentrations in blood serum during the first trimester of normal and pathological pregnancy.
abstract: Relaxin and human chorionic gonadotropin (HCG) were determined in the blood serum of women during normal and pathological pregnancy in the 1st trimester. In normal pregnancy, the hormones showed similar behavior in their secretion pattern up to the 7th week with continuously increasing concentrations. Thereafter different patterns in their secretion developed. In pathological pregnancy, both relaxin and HCG concentrations were significantly lower than in undisturbed pregnancy, following an almost parallel course without peaks.
