A retrospective analysis of perinatal information of 7,924 confinements in the calendar year of 1994 was performed to determine whether fetal sex was a significant risk factor for fetal distress in labour leading to abdominal delivery. The sex of the fetus (male) was a significant, independent, risk factor for Caesarean section (odds ratio = 1.26, 95% CI = 1.05 to 1.50). This increase was wholly attributable to the increased risk of having fetal distress in labour (odds ratio = 1.76, 95% CI = 1.32 to 2.34). Male fetuses are at higher risk of developing fetal distress during labour.
