Mothers who conceive using assisted reproductive technology may breastfeed for shorter durations than mothers who conceive spontaneously, a new study found. Breastfeeding outcomes (initiation and duration at 8 weeks) were reported among 15,615 women who conceived using fertility treatments (assisted reproductive technology, intrauterine insemination, or fertility-enhancing drugs). Researchers found:
- Mode of conception was not associated with breastfeeding outcomes when comparing women who conceived spontaneously vs those who conceived using any fertility treatment.
- The odds of breastfeeding at 8 weeks were lower among women who conceived using assisted reproductive technology, after adjusting for basic demographic covariates and additionally adjusting for maternal health conditions.
- Mothers who conceive using assisted reproductive technology may breastfeed for shorter durations, partially mediated by an increased likelihood of multiples and infants born preterm.
