BACKGROUND: Obstetric and perinatal outcomes depend not only on care during pregnancy, as there is an increasing evidence of their relationship with preexisting conditions. Woman's age and time to pregnancy (TTP) have been related to the prognosis in reproductive success, but TTP could influence fetal well-being and newborn. According to the World Health Organization, 48 million couples have subfertility globally.
METHODS: We analyzed the relationship between TTP and obstetric (premature labor, preeclampsia…), labor (type of delivery, postpartum hemorrhage…), and neonatal outcomes (low birth weight…) in a cohort of 190 spontaneous gestations. Subfertility is a disease defined by the failure to achieve a pregnancy after 12 months of regular unprotected sexual intercourse.
RESULTS: TTP was >12 months in 23.1 % (95 % CI = 17.57-29.55), however, no correlation was found with the perinatal outcomes (p = 0.24). We observed that 45.2 % of subfertile women had obstetric complications, 13.2 % labor complications, and 34.2 % neonatal complications, whereas non-subfertile women had 29.4 %, 21.0 %, and 21.0 %, respectively. Half of pregnancies have at least one adverse outcome, and obstetric complications were the most frequent.
CONCLUSION: Subfertility condition may appear in up to a fifth of our couples. Subfertility may behave as a mild risk factor for adverse perinatal outcomes. Obstetric or perinatal complication may be expected in up to half of the cases. Subfertile women ≥ 35 years of age have a 3-fold increase in their risk of having an obstetric complication when compared to non-subfertile women of the same age.
