What this trial studies

This observational study aims to assess the long-term physical, mental, and motor development of children born from various endometrial preparation protocols used in frozen embryo transfer, specifically focusing on natural, modified natural, and artificial cycles. Building on findings from a previous randomized controlled trial, the study will utilize The Ages & Stages Questionnaires® to evaluate developmental outcomes up to 24 months after birth. The goal is to provide insights into the safety and efficacy of these preparation regimens on the health of IVF/ICSI children.

Why it matters

Potential benefit: If successful, this study could enhance understanding of the safest endometrial preparation protocols, potentially leading to improved health outcomes for IVF/ICSI children.

How similar studies have gone: While this study builds on previous research, it focuses on a novel aspect of child development related to different endometrial preparation protocols, which has not been extensively studied.
