A study published in JAMA Network Open suggests that parental fertility challenges—not IVF itself—are linked to small differences in children’s neurodevelopment. Researchers found that children of parents facing infertility showed higher odds of autism-like traits and ADHD, regardless of whether medical fertility treatments were used during conception.
What did the ECHO Cohort study reveal?
Researchers analyzed data from 15,382 mother-child pairs across 44 study sites in the United States and Puerto Rico. This research, funded by the National Institutes of Health (NIH) Environmental influences on Child Health Outcomes (ECHO) Program, tracked children between the ages of 2 and 10.
The study categorized pregnancies based on medical history, including infertility diagnoses, multiple miscarriages, and the amount of time spent trying to conceive. By combining medical records with parent-completed questionnaires, the team identified specific developmental patterns.
According to the study findings, children of parents with fertility challenges demonstrated slightly higher behavior-problem scores and more autism-like traits. These differences appeared even in children conceived without the use of fertility treatments.
Is IVF responsible for neurodevelopmental differences?
A critical distinction emerged in the data regarding different types of fertility assistance. The research found that conception using non-in vitro fertilization (IVF) treatments was associated with higher odds of ADHD compared to natural conception.
However, the researchers did not find clear evidence linking IVF specifically to neurodevelopmental outcomes. This distinction is vital for families evaluating reproductive options.
| Conception Method | Associated Neurodevelopmental Finding |
|---|---|
| In Vitro Fertilization (IVF) | No clear association found |
| Non-IVF Fertility Treatments | Higher odds of ADHD |
| Fertility Challenges (No Treatment) | Higher autism-like traits and behavior issues |
Why are underlying fertility issues the likely cause?
The data suggests that the medical procedures used to achieve pregnancy may not be the primary driver of developmental differences. Instead, the biological or environmental reasons why a couple struggles to conceive may play a larger role.
Linda Kahn, PhD, an ECHO researcher at NYU Langone Health, noted that the associations likely stem from the parents’ original fertility problems. These underlying issues could be driven by genetic factors, environmental influences, or other biological drivers.
“This study contributes to the growing body of evidence indicating that infertility treatment itself is not independently associated with child neurodevelopment outcomes. Rather, it appears that the parents’ underlying fertility problems… are likely driving these associations.”

This finding shifts the focus for medical professionals. Future fertility counseling may prioritize identifying the root cause of subfecundity to better understand potential developmental contexts for future children.
Frequently Asked Questions
Does IVF cause autism in children?
According to the ECHO study, there is no clear evidence that IVF is associated with neurodevelopmental outcomes like autism.
What is the link between ADHD and fertility treatments?
The study found that children conceived using non-IVF fertility treatments had higher odds of ADHD compared to those conceived naturally.
Does infertility alone affect child behavior?
Yes. The research indicates that children of parents with fertility challenges showed slightly higher behavior-problem scores and autism-like traits, even without medical intervention.

Boost its search engine visibility with relevant keywords for maximum impact. Immunotherapy resistance remains one of the biggest hurdles in cancer treatment. According to a recent study published in the journal Nature Communications, scientists at the Salk Institute have made a groundbreaking discovery that sheds light on the underlying mechanisms behind this resistance. The study reveals that interferons, a type of protein that plays a crucial role in the immune system, can contribute to mitochondrial dysfunction in cancer cells. This dysfunction can lead to the production of prostaglandin E2 (PGE2), a molecule that promotes tumor growth and resistance to immunotherapy. In their study, the researchers found that PGE2 production was a key factor in the development of immunotherapy resistance in cancer cells. The team used a combination of experimental and computational models to investigate the relationship between interferons, mitochondrial dysfunction, and PGE2 production. The findings of the study suggest that targeting PGE2 production could be a potential strategy for overcoming immunotherapy resistance. The researchers propose that blocking PGE2 receptors or inhibiting its production could help restore the function of mitochondria in cancer cells, making them more susceptible to immunotherapy. The study’s authors hope that their findings will pave the way for the development of new therapies that can overcome immunotherapy resistance and improve treatment outcomes for cancer patients.
