Listen up ladies & gentleman – this could be a game changer. Scientists are working on combining birth control & jewellery. The idea is based around the skin patch technology, the patch which contains the contraceptive hormone is placed on the back of the earring therefore allowing women to change the front of the earring whenever they like but keep wearing the back of the earring. Further research is needed to make sure it is safe for humans & importantly effective as a birth control but imagine it could then be used with so make other forms of jewellery including watches & necklaces.
