More than 45 million couples worldwide grapple with infertility, but current standard methods for diagnosing male infertility can be expensive, labor-intensive and require testing in a clinical setting. Cultural and social stigma, and lack of access in resource-limited countries, may prevent men from seeking an evaluation. Investigators at Brigham and Women’s Hospital and Massachusetts General Hospital set out to develop a home-based diagnostic test that could be used to measure semen quality using a smartphone-based device. New findings by the team indicating that the smartphone-based semen analyzer can identify abnormal semen samples based on sperm concentration and motility criteria with approximately 98 percent accuracy are published online on March 22 in Science Translational Medicine.
