Spermbot for male infertility

Researchers have come up with a novel way to help couples conceive using spermbots. Tiny magnets attached to sperm may be a future way to help increase a a couple's chance of conceiving.. Watch a video of the little guys working.


What is a spermbot?

The concept isn't exactly new. But now German researchers are even closer to developing tiny little sperm shaped swimmers that can be used to propel men's sperm forward to reach target. The treatment could be used for low sperm motility.

The newest finding appears in the ACS journal Nano Letters. Spermbots are better than present fertilization techniques that can be either expensive or simply fail.

One of the new features of the artificially propelled sperm is that the researchers have developed tiny metal devices that fit on the tails of sperm. They use magnetic devices to drive sperm into a woman's egg. The motorized sperm can then be released.

Micro motors that drive sperm to a woman's egg are not ready for clinical testing, but scientists are closer to finding a way to treat male infertility from low sperm motility. The spermbot may someday replace more costly, invasive procedures to help couples conceive.
