Relaxin concentrations in exoembryonic fluids during the first trimester.
In 15 women undergoing therapeutic termination of pregnancy (8-13 weeks), the median concentration of relaxin was 1000 ng/l in maternal serum, 122 ng/l in coelomic fluid and 9 ng/l in amniotic fluid. Its presence in coelomic fluid suggests that relaxin may be present in the fetal circulation and thus be able to influence embryonic development during the period of organogenesis.
