“A micro-robot that can travel into women’s fallopian tubes and drill out obstructions, allowing them to conceive, is being developed by scientists.

Blockages between ovaries and womb that prevent sperm from reaching the egg are one of the major causes of infertility in women.

The new device, developed by Shenzhen Institute of Advanced Technology (SIAT) in China, shaped like a tiny self-tapping screw, is activated by a magnetic field which allows it to rotate.

As the screw turns, it breaks up any obstructions, and also generates a vortex which sucks debris back towards its tail and out of the way.”
