Summary
Maternal smoking significantly impairs fertility and increases risks of miscarriage and ectopic pregnancy. Quitting smoking can reverse these effects on fertility, but more research is needed on smoking cessation
Area of Science:
- Reproductive Health
- Epidemiology
- Obstetrics
Context:
- Smoking prevalence among couples of reproductive age in France remains high.
- Despite recommendations, many continue smoking before or during pregnancy.
- Existing research highlights associations between parental smoking and adverse reproductive outcomes.
Purpose:
- To review epidemiological associations between maternal/paternal smoking and infertility.
- To examine the link between maternal smoking and very preterm birth (VPTB).
- To assess the reversibility of smoking's detrimental effects on fecundity.
Summary:
- Maternal smoking demonstrably impairs both natural and assisted fertility.
- Smoking increases the likelihood of ectopic pregnancies and spontaneous abortions.
- Evidence links maternal smoking to very preterm birth, though effects in specific subgroups (hypertensive mothers, primiparae) require further study.
Impact:
- Smoking cessation by both parents can reverse negative impacts on fecundity.
- Further research is needed to evaluate the effectiveness of smoking cessation interventions during pregnancy on reducing VPTB rates.
- Findings underscore the importance of smoking cessation for reproductive health and pregnancy outcomes.
