At-Home Male Fertility Test App Takes Sperm Selfies - Scientific American

A debate has raged for decades over whether male fertility is declining, according to some analyses of studies from recent decades. The latest study of a new at-home test kit, published today in Science Translational Medicine, found that even untrained users were able to measure sperm count and concentration as well as motility the percentage of actively moving sperm , detecting abnormal semen with 97 percent accuracy compared with traditional lab testing. Developed by researchers at Harvard Medical School, the system uses a smartphone app with a 3-D—printed optical attachment to record a video of sperm cells in a sample. Software algorithms then analyze the video to count the sperm and assess their movement. The user simply slides the brick-shaped magnifying optical attachment onto the back of a smartphone, then loads a semen sample into a disposable microchip device that looks like a flattened eyedropper, which is inserted into a slot in the device.

Fortunately, as the human body has evolved over thousands of years to maximize fertility potential, so has our scientific understanding about sperm. But many of us still believe some pretty unscientific, long-standing sperm myths.
