Offspring of subfertile parents. A preliminary survey
Insights
Subfertility in parents significantly impacts neonatal outcomes, with 18% of livebirths experiencing adverse events. However, children of subfertile parents who survive infancy show no developmental or learning differences compared to the general population.
Area of Science:
- Reproductive Medicine
- Neonatal Health
- Pediatric Development
Background:
- Subfertility affects a significant portion of couples seeking parenthood.
- The long-term health and developmental outcomes for offspring of subfertile parents require further investigation.
- Previous research indicates potential risks during the neonatal period for these children.
Purpose of the Study:
- To assess the neonatal morbidity and mortality rates in livebirths to subfertile parents.
- To evaluate the developmental trajectory, including malformations and learning disorders, in children born to subfertile parents.
- To compare the health and developmental outcomes of children from subfertile versus fertile parent populations.
Main Methods:
- A preliminary survey was conducted on livebirths of subfertile parents.
- Data collected included neonatal death, low birth weight, and major anomalies.
- Follow-up information on developmental delay, malformations, and behavioral/learning disorders was gathered for surviving children.
Main Results:
- 18% of livebirths (11 out of 60) experienced adverse neonatal outcomes, including death, low birth weight, or major anomalies.
- Neonatal morbidity and mortality were significantly influenced by parental subfertility.
- Among 49 children with available follow-up data, no cases of developmental delay or increased malformations were observed.
Conclusions:
- Parental subfertility is associated with increased neonatal risks.
- Children of subfertile parents who survive the neonatal period appear to have outcomes comparable to the general population.
- Further research with larger cohorts is warranted to confirm these preliminary findings.
Abstract:
This preliminary survey reports findings among offspring of subfertile parents. Combining neonatal death, low birth weight and major anomalies, 11 of 60 livebirths (18%) were affected, indicating that subfertility adversely influences neonatal morbidity and mortality. Information was available for 49 of 56 children and there were none with developmental delay nor was there an increase in malformations or minor behavioral or learning disorders. Although numbers are small, these observations suggest that children of subfertile parents who survive the neonatal period do not differ from the normal population.
