SCIENTISTS have developed turbo-charged robotic sperm to help treat infertility-causing conditions affections millions of women, including uterine cancer, endometriosis and fibroids.

The new technology could provide a closer look into the body during fertilisation, helping understand unexplained infertility, and potentially improve IVF techniques.

Researchers from the University of Twente, in the Netherlands, transformed sperm cells into microscopic robots by encasing them in magnetic nanoparticles.

This allowed sperm to both be tracked in real time and steered for the first time.

"We're turning nature's own cell delivery systems into programmable microrobots," said study lead author Islam Khalil , an associate professor in the robotics and mechatronics research group at the uni
