Smartphone-Based Test for Male Fertility
Current standard methods for diagnosing male infertility can be expensive, labor-intensive, and require testing in a clinical setting. Researchers from Brigham and Women's Hospital, Massachusetts General Hospital, and Harvard Medical School have developed an automated smartphone-based diagnostic assay that offers an inexpensive way to measure sperm concentration and motility at home rather than in the clinic. The analyzer consists of an optical attachment that connects to a smartphone and a disposable device onto which a semen sample can be loaded. A disposable microchip with a capillary tip and a rubber bulb is used for simple, power-free semen sample handling. The team also designed a user-friendly smartphone application that guides the user through each step of testing, and a miniaturized weight scale that wirelessly connects to smartphones to measure total sperm count.
