Genetic Studies in Assisted Reproduction Unveiling the Risk of Congenital Anomalies

Introduction

The journey to parenthood through assisted reproductive technologies (ART) has transformed the lives of countless couples worldwide. However, concerns about the potential risk of congenital anomalies among children conceived through in vitro fertilization (IVF) continue to spark important scientific discussions. A recent observational study conducted by researchers from the National and Kapodistrian University of Athens sheds light on these concerns by analyzing genetic outcomes among children born via ART.

Key Findings from the Study

The study evaluated 230 children and adolescents conceived through ART and treated at the Clinical Genetics Clinic of Aghia Sophia Children’s Hospital. Key findings included:

• Psychomotor retardation was the most commonly observed anomaly (35.53%).
• Facial and spinal cord abnormalities were observed in 23.68% of cases each.
• Morphological abnormalities (21.05%) and short stature (20.61%) were also prevalent.
• Karyotype chromosome analysis revealed pathological results in 10.43% of the cases.
• Molecular DNA analysis showed 21.74% had identifiable genetic issues.

Broader Medical Insights

While congenital anomalies in ART offspring raise concern, findings indicate that the absolute risk remains limited. This is in alignment with previous research by the American Society for Reproductive Medicine (ASRM), which emphasizes that while ART may slightly elevate risks, proper screening and medical interventions can greatly mitigate potential adverse outcomes.

Key broader findings include:

• Maternal age is associated with chromosomal anomalies.
• Cryopreservation techniques showed no significant risk increase.
• Full-term pregnancies in ART cases had a higher incidence of cranial morphological abnormalities.

Genetic Screening Recommendations

The study recommends comprehensive genetic screening of both oocyte and sperm donors to protect the health of future offspring. Early diagnosis and interventions based on genetic testing can improve clinical outcomes significantly.

• Screening reduces the likelihood of severe congenital anomalies.
• It safeguards not only the child but also supports the well-being of parents and donors.
