Births following oral contraceptive failures
Obstetrics and Gynecology
|April 1, 1980
Summary
Oral contraceptive failure during early pregnancy is linked to adverse neonatal outcomes. This includes higher rates of birth defects and perinatal mortality, especially in infants born to younger mothers.
Area of Science:
- Reproductive Health
- Neonatal Studies
- Teratology
Background:
- Oral contraceptives (OCs) are widely used for birth control.
- Accidental pregnancy while using OCs can lead to unintended exposures.
- Previous studies suggest a potential link between OC failure and adverse pregnancy outcomes.
Purpose of the Study:
- To investigate the neonatal outcomes of infants conceived during maternal oral contraceptive use.
- To identify specific risks and malformations associated with oral contraceptive failure.
Main Methods:
- Retrospective study of 108 infants conceived during oral contraceptive use.
- Analysis of maternal demographics, exposure history, and infant health outcomes.
- Comparison with expected rates of malformations and mortality.
Main Results:
- Infants were more likely born to younger, less educated mothers.
- Increased exposure to hormonal pregnancy tests noted.
- Ten newborns (8 males) had malformations, including anencephaly and Down's syndrome.
- Significantly higher rates of twins and excess perinatal mortality observed.
Conclusions:
- Oral contraceptive failure is associated with a small but increased risk of adverse neonatal outcomes.
- Findings highlight the need for effective contraception and early prenatal care.
- Further research is warranted to elucidate mechanisms and confirm risks.
