Summary

Assisted hatching (AH) can improve implantation rates, particularly for women with recurrent implantation failures. Further research is needed to refine patient selection and evaluate AH

Area of Science:

  • Reproductive medicine
  • Embryology
  • Infertility treatments

Background:

  • Assisted hatching (AH) is widely used in fertility centers globally to enhance embryo implantation.
  • The zona pellucida (ZP) is a protective layer around the embryo that AH aims to breach.
  • Existing studies on AH efficacy have yielded inconsistent results across various clinical scenarios.

Purpose of the Study:

  • To analyze the effectiveness of assisted hatching (AH) in improving pregnancy outcomes.
  • To clarify the complex indications for AH based on available clinical evidence.
  • To reevaluate the role of AH in assisted reproductive technology (ART).

Main Methods:

  • Review and synthesis of retrospective and prospective studies on AH over 13 years.

Related Experiment Videos

  • Assessment of AH's impact on implantation rates in different patient groups.
  • Consideration of embryo selection criteria and culture methods.

    • Main Results:

    • Assisted hatching demonstrates a clear benefit for women experiencing repeated embryo implantation failures.
    • The disparate results from studies highlight the complexity in selecting appropriate candidates for AH.
    • Optimal embryo selection using morphometric criteria or extended culture to blastocyst stage is crucial.

    Conclusions:

    • Assisted hatching is most beneficial for patients with a history of recurrent implantation failure.
    • The clinical application of AH requires careful patient and embryo selection, potentially involving advanced embryo assessment techniques.
    • The value of AH for indications beyond repeated failure needs cautious evaluation to avoid negative impacts on implantation success.
