Total fertilization failure with in vitro fertilization-intracytoplasmic sperm injection related to WEE2 mutation highlights emerging importance of genetic causes of in vitro fertilization failure. | LitMetric

AI Article Synopsis

  • A case report discusses a unique instance of total fertilization failure (TFF) after in vitro fertilization due to a specific genetic mutation in a couple.
  • The 25-year-old woman displayed near-complete fertilization failure in two IVF cycles, prompting genetic testing that revealed she was homozygous for a pathogenic variant affecting oocyte activation.
  • The report emphasizes the importance of genetic testing for couples facing TFF to improve decision-making and reduce the emotional and financial stress of unsuccessful fertility treatments.

Article Abstract

Objective: To report a unique case of total fertilization failure (TFF) after in vitro fertilization with intracytoplasmic sperm injection related to homozygous gene mutation and summarize the current literature and management of TFF.

Design: Case report.

Setting: Academic fertility center.

Patients: A 25-year-old woman and her 35-year-old partner with a history of near-complete fertilization failure after 2 cycles of in vitro fertilization/intracytoplasmic sperm injection.

Interventions: Consultation with medical and commercial genetic testing for , , and .

Main Outcome Measures: Oocyte fertilization.

Results: The patient was homozygous for pathogenic variant impacting oocyte activation and resulting in infertility.

Conclusions: In the setting of TFF, early consideration should be given to genetic testing to assist couples in clinical decision-making and help limit the financial and emotional burden associated with unsuccessful fertility intervention.
