Understanding how sperm and egg interact: New discoveries about fertilization.
Reading
Scientists have long wondered how sperm and egg come together. New research suggests a lock and key system helps this happen in many animals, including humans.
A team of scientists found that three proteins on the sperm work together like a key. This key unlocks the egg and lets the sperm attach.
The scientists used a special computer program called AlphaFold to find the proteins. This program helped them understand how the proteins work in living animals.
While this discovery is a big step, scientists still don't know how the sperm gets inside the egg after attaching. They hope to study this next.
Understanding this process better could help scientists learn more about infertility. It could also lead to new ways to prevent pregnancy.
