The most common side effect with all the implants was changes in bleeding pattern. Rates of amenorrhoea after two years use were significantly higher in women using Implanon than Norplant. Implanon was also quicker to implant and remove than Norplant, and Jadelle was quicker to remove that Norplant.
“One way of judging the acceptability of a contraceptive is to see whether women are able to use them over a long period of time, there are indications of good tolerability in that over 80% of women in the studies continued to use their contraceptive implants for two or more years,” says lead researcher Jo Power, who works at the Margaret Pyke Centre in London, UK.
The data also showed that women in developing countries were more likely to continue using them than were women from developed countries.
“Menstrual disturbances are common however, and these side effects should be explained to women before the implant is inserted so that women can make an informed choice about their contraceptive strategy,” says Power.

World first experiments on sensor that may revolutionise everything from medical devices to unmanned vehicles
The new sensor - capable of detecting vibrations of living cells - may revolutionise everything from medical devices to unmanned vehicles.
Dead and alive at the same time? Researchers at the Max Planck Institute of Quantum Optics have implemented Erwin Schrödinger’s paradoxical gedanken experiment employing an entangled atom-light state.
In 1935 Erwin Schrödinger formulated a thought experiment designed to capture the paradoxical nature of quantum physics. The crucial element of this gedanken...
Cellulose obtained from wood has amazing material properties. Empa researchers are now equipping the biodegradable material with additional functionalities to produce implants for cartilage diseases using 3D printing.
It all starts with an ear. Empa researcher Michael Hausmann removes the object shaped like a human ear from the 3D printer and explains:
The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.
One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
