Intracytoplasmic sperm injection (ICSI) offers an alternative for male infertility, but should be reserved for specific cases. Careful consideration of indications is crucial for optimizing its use in assisted reproduction.

Area of Science:

  • Reproductive Medicine
  • Andrology
  • Infertility Treatment

Background:

  • Intracytoplasmic sperm injection (ICSI) is a microfertilization technique primarily used for severe male subfertility.
  • While ICSI shows promising results, it is considered novel with largely unexplored safety aspects.

Purpose of the Study:

  • To outline and discuss the non-existent, relative, and absolute indications for performing ICSI.
  • To guide the appropriate application of ICSI in assisted reproductive technologies.

Main Methods:

  • Review and discussion of existing clinical data and expert opinion on ICSI indications.
  • Categorization of indications into non-existent, relative, and absolute.

Main Results:

  • ICSI is not recommended for the first cycle with a normal sperm sample, even with few oocytes.
  • Relative indications include subnormal sperm, antisperm antibodies, or prior poor fertilization with conventional IVF.
  • Absolute indications encompass previous fertilization failures, use of testicular/epididymal sperm, acrosomeless/immotile sperm, and oocyte fertilization before preimplantation genetic diagnosis.

    • Conclusions:

    • ICSI should be reserved for specific indications due to its novel nature and unexplored safety.
    • Indications for ICSI should remain flexible, adapting to new research findings and clinical outcomes.
