Health of Babies Born From IVF Versus IVM at 5 Years Old (FM-BABIES-5Y)

Long-term Developmental and Behavioral Outcomes of Children Born From CAPA-IVM Versus Conventional IVF at 5-year-old

The investigators conduct a long-term follow-up at five years on offspring born from our randomized controlled trial (RCT) to investigate whether or not there is any difference in developmental outcomes in children born after capacitation IVM (CAPA IVM) compared with conventional IVF in order to give strong evidence about the safety of IVM in women with high antral follicle count.

Study Overview

• Status: Completed
• Conditions: Infertility; IVF; Development, Child; IVM
• Intervention / Treatment: Other: Developmental score according to The Ages & Stages Questionnaires®, Third Edition - ASQ®-3 and behavioural screening according to Strength and Difficulties Questionnaires (SDQ's)

Detailed Description

The safety of the CAPA-IVM has also been proven by publications about the development of children born from this technique.

Data monitoring the physical, mental, and motor development of children born from the CAPA-IVM versus children born from the conventional IVF after 2 years under using the ASQ-3 tools and red flags showed that there were no significant differences in ASQ-3 scores at 6, 12 and 24 months between children born after IVM or IVF. The proportion of children with developmental red flags was low and did not differ between the two groups. Slightly, but significantly, lower ASQ-3 problem-solving and personal-social scores in twins from the IVM versus IVF group at 6 months were still within the normal range and had caught up to the IVF group in the 12- and 24-month assessments.

However, another question raised is whether there is a difference in the development of children born from CAPA-IVM compared to conventional IVF after a longer follow-up period. Does the development between the two groups have a clinically significant difference? Based on these questions, we decided to conduct an assessment of the physical, behavioural, mental, and motor development of children born from CAPA-IVM and conventional IVF up to 5 years after birth.

Cohorts and Interventions

Group / Cohort	Intervention / Treatment
IVM children; Children born from in-vitro maturation.	Other: Developmental score according to The Ages & Stages Questionnaires®, Third Edition - ASQ®-3 and behavioural screening according to Strength and Difficulties Questionnaires (SDQ's); Ages & Stages Questionnaires®, Third Edition (ASQ®-3) is a developmental screening tool designed for use by early educators and health care professionals. It relies on parents as experts, is easy to use, family-friendly and creates the snapshot needed to catch delays and celebrate milestones. The ASQ-3 covers five developmental domains: communication, gross motor, fine motor, problem-solving and personal-social behaviour. The Strengths and Difficulties Questionnaire (SDQ) is a brief behavioural screening questionnaire for 2-17-year-olds. It exists in several versions to meet the needs of researchers, clinicians and educationalists. The SDQ asks about 25 attributes, some positive and others negative. These 25 items are divided between 5 scales: emotional symptoms, conduct problems; hyperactivity/inattention, peer relationship problems, and prosocial behaviour

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Normal ASQ-3 score rate.	A normal ASQ-3 score is the child's total score for each area above the cutoff. ASQ-3 (Ages and Stages Questionaires®) has 5 aspects: Communication, Gross motor, Fine motor, Problem solving, and Personal-Social Each aspect has 6 questions, if the answer is Yes, score = 10, Sometimes = 5 and Not yet = 0. ASQ-3 score = total area scores.	Up to 5 years after birth
Normal SDQ score rate.	Normal SDQ score is defined as the total score of each area out of the abnormal range for each one. Abnormal range for each area is described as below: emotional symptoms: from 5 to 10; conduct problems: from 4 to 10; hyperactivity/inattention: from 7 to 10; peer relationship problems: from 4 to 10; prosocial behaviour: from 0 to 4; The total difficulties score: from 17 to 40	Up to 5 years after birth
Normal weight rate	Normal weight is a BMI greater than or equal to -2 standard deviations and less than or equal to 1 standard deviation of the WHO growth reference median.	Up to 5 years after birth

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Thinness rate	Thinness is a BMI less than -2 standard deviations below the WHO growth reference median.	Up to 5 years after birth
Overweight rate	Overweight is a BMI greater than 1 standard deviations above the WHO growth reference median.	Up to 5 years after birth
Obesity rate	Obesity is a weight greater than 2 standard deviations above the WHO growth reference median.	Up to 5 years after birth
