Nano Patents and Innovations: Home Test For Men: Fertility Chip Measures Concentration And Motility Of Semen:
Loes Segerink, a researcher at the University of Twente has developed a “fertility chip” that can accurately count sperm and measure their motility. The chip can be inserted into a compact device for one-off use. A home test kit will soon make it possible for men to test their sperm in a familiar environment. As a result, there is a greater chance of obtaining a correct diagnosis, also the method is simple and inexpensive.
The lab-on-a-chip developed by Segerink measures sperm concentration. The importance of the sperm concentration is that the fertility standard states that a millilitre of ejaculate should contain at least 20 million sperm. A second important aspect of fertility is motility. This too can be measured using the lab-on-a-chip. Simple home test kits are already commercially available. These indicate whether the concentration is “above or below the standard value”. These tests are too limited, however, as they do not give accurate concentration readings.
How does it work?
