Scientists develop injection for long-lasting contraceptive implant

Approach could herald new way of delivering drugs, beyond birth control, over long periods of time

Researchers are developing an injection that creates a contraceptive implant in the body using an approach that could herald a new way of delivering drugs over long periods of time.

Current contraceptive implants last for years, meaning women do not have to take a pill every day, but the devices must be fitted by a trained professional via a small surgical procedure. Contraceptive injections are already available but they have limitations, including that they last for only three months.
