Guideline-Based Recommendations

Diagnosis

Assess neurodevelopmental outcomes using caregiver-reported measures.

Management

Consider parental subfecundity as a factor in assessing child behavioral outcomes.

Monitoring & Follow-up

Monitor children born to parents with a history of subfecundity for behavioral difficulties.

Risks

Higher externalizing behavior scores and increased odds of ASD and ADHD in children of parents with subfecundity.

Patient & Prescribing Data

Parents with a history of infertility or subfecundity

Non-IVF infertility treatments may be linked to higher ADHD rates.

Clinical Best Practices

Evaluate the impact of parental fertility issues on child development.
Utilize comprehensive assessments for children with a parental history of subfecundity.
