Area of Science:

  • Reproductive Biology
  • Andrology
  • Genetics

Background:

  • Sperm morphology is insufficient for assessing fertilization potential and embryo health.
  • Idiopathic infertility may stem from genetic and epigenetic factors.
  • Posttranslational modifications are key to understanding fertilization and offspring development.

Purpose of the Study:

  • To explore novel sperm markers for successful assisted reproductive therapies (ART).
  • To investigate the role of sperm epigenetic status in fertilization and embryo development.
  • To review non-invasive sperm selection techniques for improving ART outcomes.

Main Methods:

  • Review of current literature on sperm markers and selection techniques.
  • Focus on epigenetic modifications as potential quality indicators.
  • Evaluation of non-invasive methods like microfluidics, nanopurification, and Raman spectroscopy.

Main Results:

  • Traditional sperm selection methods can be harmful.
  • Novel techniques offer non-invasive assessment of sperm quality.
  • Epigenetic markers combined with gentle selection show promise for ART.

Conclusions:

  • Integrating sperm epigenetic analysis with non-invasive selection methods can significantly improve ART success.
  • Further research into these novel approaches is warranted for clinical application.
  • This strategy promises healthier embryos and offspring through advanced reproductive technologies.
