title: Is sex of fetus associated with duration of labor in nulliparas?
abstract: In a post facto study to examine whether sex of fetus was related to duration of nulliparas' labor 30 nulliparous (had not given birth previously) women who delivered boys and 30 others who delivered girls were matched according to the criteria that they were nulliparous, received an epidural for analgesia during labor, and their labors were either induced or augmented. All delivered vaginally. Duration of labor was not statistically significantly related to sex of the fetus.
