Helping hundreds of providers move patient care forward

1 of 9

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

As a vasectomy provider and fertility specialist, Fellow’s mail-in semen analysis allows my patients to provide a sample from the comfort of their home and get excellent laboratory-quality analysis and results. Fellow has simplified the process for my clinic to ensure patients get tested and I would highly recommend Fellow’s semen analysis for any patient or physician.

Sijo J. Parekattil, MDDirector of Avant Concierge Urology, Winter Garden, FL

We are very happy with Fellow and never want to go back! The whole clinic is happy to use Fellow, especially the providers. I even had a patient come in recently who was supposed to bring us in a sample and I offered him the option of a Fellow kit to do from home. He jumped on the option of buying the Fellow kit and was super excited to be able to do it all from home so that it was simpler for him.

* Turn around time of less than 2 days from receipt of sample to report.

† Patient compliance compares tests ordered in a 6 month period to tests accessioned anytime up to 6 months after the order period.

** Multiple publications report only 1 in 2 patients complete post-vasectomy semen analysis, including [1] Bradshaw (Hseih) et al., Urology, 2019, doi: 10.1016/j.urology.2019.10.026, [2] Duplisea and Whelan, Journal of Urology, 2013, doi: 10.1016/j.juro.2013.01.062 and [3] Johnson (Siegert) et al., Andrology & Gynecology: Current Research, 2019.
