NCT ID NCT05502770
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study follows 700 children born from frozen embryo transfer to see if the way the mother's womb was prepared affects the child's development. Researchers compare three common methods: natural cycle, modified natural cycle, and artificial cycle. Parents answer questionnaires about their child's communication, motor skills, and problem-solving at age 2.
