American experts who developed the technology based it on the same principle as existing long-lasting contraceptive implants that are inserted surgically, usually into the arm.
Scientists in the US have developed a self-injectable contraceptive jab containing microscopic crystals that release hormones over a prolonged period to prevent pregnancy. Preliminary rat studies show it is safe and effective, potentially offering a more accessible, long-lasting alternative to the daily pill or implanted devices, especially in low-resource settings. The scientists are exploring its potential for other long-release drugs.
