Spermbot could help solve male infertility - Headline Science

One of the main causes of infertility is low sperm motility. Sperm that are healthy, but can’t swim. Now a team of scientists has developed a possible solution: the Spermbot. Oliver Schmidt, Ph.D. and his team at the IFW in Dresden, Germany built a tiny metal helix controlled by a rotating magnetic field. The Spermbot can wrap around a sperm and drive it into an egg, leading to possible fertilization. The research appears in the ACS journal Nano Letters. Original article:
