Assisted oocyte activation following ICSI fertilization failure

Area of Science:

• Reproductive Biology
• Assisted Reproductive Technology

Background:

• Intracytoplasmic sperm injection (ICSI) is highly successful for male factor infertility.
• Fertilization failure post-ICSI affects 1-3% of couples, necessitating alternative strategies.

Purpose of the Study:

• To review human oocyte activation mechanisms and ICSI fertilization failure.
• To evaluate the application, efficiency, and safety of Assisted Oocyte Activation (AOA) in human reproduction.

Main Methods:

• Literature review of oocyte activation and ICSI.
• Analysis of diagnostic approaches for fertilization failure.
• Assessment of AOA techniques and outcomes.

Main Results:

• ICSI failure is rare but significant.
• AOA is increasingly used to improve fertilization and pregnancy rates.
• Concerns exist regarding AOA's artificial agents mimicking natural activation processes.

Conclusions:

• AOA shows promise for overcoming ICSI fertilization failure.
• Further research is needed to address safety concerns and optimize AOA protocols.
• Understanding oocyte activation is crucial for improving assisted reproduction outcomes.
