Human procreation is all about accuracy alongside volume. Out of around 350 million sperm, only about a hundred of them might be able to navigate correctly, but only one will end up leading to fertilization. The odds are terrible, but thanks to science and technology we can now rely on one sperm to always get the job done. Researchers in Germany have successfully created and tested something to turn the tables around with “spermbots.” Spermbots were created to help with the mobility of a sperm and successfully guide it to fertilization. For some reason, sperm tend to have poor mobility, and so they are deterred from the right path

The spermbot is a magnetically-driven power suit for individual sperm that can be remote controlled all the way to the egg. Methods like artificial insemination or in vitro fertilization can be of help, but they are not that reliable and comes included with chances of failure. In order to prevent such mishaps, the spermbot was designed to be equipped with a motor and user to navigate its way.

The motor are metal-coated polymer microhelices that fit perfectly over the tail of a sperm. A rotating magnetic field that causes them to cycle, moving them (and whatever sperm they’re attached to) forward. Adjusting the orientation of the field can steer the spermbots in 3D, and all of this stuff can be done inside of an MRI machine, although the video (and testing so far) has been in the equivalent to a Petri dish. Once the (dizzy) sperm reaches the egg, the micro- motor can even plow them into it, making the fertilization process quick and simple
