Brief summary
This study aims to investigate the effects of trophectoderm (TE) biopsy on the health and development of children born after preimplantation genetic testing (PGT) cycles. The blastocyst biopsy is performed as part of standard clinical practice, in accordance with established protocols and current national regulations governing assisted reproduction.
Interventions
The only additional procedure involved in this study is the administration of a questionnaire to the parents, which is not part of routine clinical follow-up. The questionnaire was originally developed in the context of the Norwegian Mother and Child Cohort Study (MoBa).
