Hyaluronic acid (HA) is a natural macromolecule found in high amounts in the extracellular matrix surrounding the human oocyte. This critical component helps bind the cumulus cells together, forming a labyrinth-like system that a mature sperm must navigate during fertilization. Understanding the role of HA is vital for appreciating the complex processes of natural reproduction and advancements in fertility treatments, clarifying if hyaluronic acid in human eggs plays a part in reproduction.
