One of the leading causes of infertility in males is low sperm motility, or the inability of the sperm to reach the eggs. A team of German researchers has developed what they have dubbed a “spermbot” which can help sperm cells reach the egg. The spermbot is a metal spiral developed on the nanoscale, just large enough to fit over the sperm’s tail and take hold beneath the head. The researchers use a rotating magnetic field to direct the spermbot to an individual sperm cell, and then use it as a motor to drive the sperm to the egg. Once there, the sperm can fertilize the egg and the spermbot’s spiral motor can simply slip off.
Tests have only been done in a petri dish setting and the technology is not yet ready for use on humans. However, once available, this technology could be far less expensive than most other infertility treatments. To learn more, please watch the video above.
