In an exciting development for contraception, MIT scientists—supported by funding from the Bill & Melinda Gates Foundation—have created an injectable solution that could release birth control over months, potentially up to a couple of years.
Here’s how it works: users receive a small injection of a crystal-based suspension under the skin. Once inside, the crystals form a long-lasting “depot” that steadily releases the contraceptive hormone levonorgestrel, minimizing both pain and the need for frequent doses. Early animal studies have shown the injection could remain effective for months—and possibly long enough to rival surgical implants—all via a thin needle.
This innovation holds major promise for birth control access, especially in areas with limited healthcare infrastructure. A simple, once‑in‑a‑lifetime injection could revolutionize contraception logistics and ensure steady protection without daily or monthly reminders.
Researchers are now working to tweak dosage levels and safety before moving into human trials. If successful, this could be a game-changer for contraception worldwide.
