We conducted a prospective study to assess serum melatonin as a biomarker to predict the development of late-term and postterm pregnancies and spontaneous beginning of labor in women with term pregnancies. Population of this prospective study included pregnant women with late-term and postterm pregnancies and term pregnancies as controls. In these study groups, serum melatonin concentrations were measured in women with or without labor and their perinatal data were collected. In the postterm pregnancies without labor, the lowest median melatonin concentrations were measured (p<0.05). In the late-term and postterm pregnancies with and without labor, the median serum melatonin concentrations were significantly lower than term ones (p<0.05). In the term pregnancies with labor, the highest median melatonin concentration was measured (p<0.05). A serum melatonin concentration
