INTRODUCTION: To investigate the existence of a relationship between fetal sex and primary cesarean section (C/S) rates.
METHODS: The demographic characteristics, birth records, and medical characteristics of 58,897 patients who gave birth in our hospital between January 2013 and December 2022 were retrospectively evaluated. A total of 14,045 patients who had a C/S during their previous births were excluded from the study. C/S rates and indications were evaluated according to the presence of male and female fetuses. Pregnancy outcomes of pregnant women in adolescent and adult groups were also assessed.
RESULTS: The mean birth length and birth weight in the adult group were found to be significantly higher (p<0.001 and p=0.008, respectively). The 1st-minute and 5th-minute APGAR scores of the adult group were significantly higher than those of the adolescent group (p<0.001 and p<0.001, respectively). A significant difference was found in the probability of primary C/S delivery between male and female fetuses in both the adolescent and adult age groups, with a significantly higher C/S rate observed in male fetuses (p<0.001 and p<0.001, respectively).
DISCUSSION AND CONCLUSION: C/S rates are becoming a public health problem in developing countries. It should be kept in mind that fetal sex influences pregnancy outcomes and C/S rates. Additionally, the frequency of some maternal, perinatal, and neonatal complications may be higher in adolescent mothers.
