Austrian Scientists Unlock the Sperm-Egg Fusion Code

In a groundbreaking 2024 study, Austrian researchers revealed the lock-and-key mechanism behind sperm and egg fusion, identifying proteins Izumo1, Spaca6, and the newly discovered Tmem81 across vertebrates, including humans. Leveraging Google DeepMind's AlphaFold, they mapped these interactions, highlighting evolutionary conservation. This discovery not only deepens our understanding of infertility but also opens doors for innovative male contraceptives. Who knew biology had such a well-guarded key?
