Swim further: new device selects sperm to improve chances of pregnancy

In 10 seconds? The female genital tract can be a hostile environment for conception, and only a few sperm will make it. Swimming in the right way is the solution but is not always happening, especially for those who have fertility issues. A new, low-cost device could help solve this problem.

Please, could you tell me more about this invention? It’s about helping couples to get pregnant. Using the natural movement of sperm, engineering researchers have developed a microfluid chip that separates healthy sperm and allows it to be used in assisted reproductive techniques. The device is easy to use (but is not meant for the home), and consists of different chambers separated by microchannels. This chip allows that motile and healthy sperm cells (i.e. those that can move) to be separated from the weak or the dead.
