Scientists have created a novel method of contraception, using polymer beads coated in a special protein as “decoy” eggs in mice. In experiments described in Science Translational Medicine, researchers deposited the beads in the uteruses of mice. When the mice mated, sperm cells bound themselves to the fake eggs, preventing the real eggs from being fertilized. The scientists from the National Institutes of Health say it’s extremely unlikely the beads would be used in their current form as human contraception, but that they do show promise as a better way to select sperm for use in fertility treatments.
