Background
Although most newborns conceived through assisted reproductive treatments are healthy, there are concerns about the safety of reproductive techniques and their effect on foetal/maternal well-being.
Objective
This study aims to describe the incidence of obstetric and perinatal complications in women undergoing assisted reproductive treatments in the Spanish Health System.
Method
This is a cross-sectional observational study aimed at women who have been mothers between 2013 and 2018 in Spain. The data was collected through an online survey of 42 items that was distributed through lactation associations and postpartum support groups. In the data analysis, crude odds ratios (OR) and adjusted odds ratios (AOR) were calculated, through a multivariate analysis with binary logistic regression and multinomial logistic regression.
Results
Five thousand nine hundred forty-two women participated, 2.3% (139) through artificial insemination and 8.2% (486) through in vitro fertilisation (IVF) techniques. Women who underwent IVF had a higher likelihood of suffering problems during pregnancy (OR = 1.71; 95% confidence intervals (95% CI), 1.37–2.13), delivery (OR = 1.43; 95% CI, 1.01–2.02), and postpartum (OR = 1.94; 95% CI, 1.40–2.69) than women with spontaneous pregnancy. No increased likelihood of neonatal problems was observed in this group except for twin pregnancy (OR = 9.17; 95% CI, 6.02–13.96) and prematurity (OR = 1.43; 95% CI, 1.01–2.02). No differences were observed between spontaneous pregnancies and those achieved by artificial insemination.
Conclusions
Pregnancies achieved through IVF present a higher risk of complications before, during and after delivery. However, there is no increased risk of neonatal problems except for a higher likelihood of twin pregnancy and prematurity.
