As a high-volume vasectomy provider, Fellow post-vasectomy testing is the perfect solution for my patients as well as my practice. My patients are now able to complete their post-vasectomy semen analysis from the privacy of their own home, thereby increasing patient compliance. Once they complete testing, Fellow sends results to both me and my patient, decreasing the call volume into my practice previously required to communicate results.David Robbins, MDUrologist at Urological Consultants of Florida, Miami, FL
Fellow is building a biobank of semen samples so that the most potent and accessible analyte—seminal fluid—can be used to yield breakthroughs across medical disciplines.Our science
