Ranjith Ramasamy

Ranjith Ramasamy is the former Director of the Reproductive Urology Fellowship program at the University of Miami's Miller School of Medicine. An American medical researcher and urologist, Ramasamy is known for academic contributions to reproductive medicine, including testosterone deficiency, regenerative therapy, erectile dysfunction, and prostate cancer studies. Ramasamy has co-authored a significant number of publications in the domain of male infertility and sexual dysfunction. Ramasamy is a recipient of the American Society for Reproductive Medicine Award.

Education
Ramasamy graduated with a B.S degree in Cell Biology and Neuroscience from Rutgers University in 2003. He continued to study at Rutgers, receiving his medical degree there in 2007. Ramasamy completed his urology residency training at Weill Cornell Medicine and NewYork-Presbyterian Hospital in 2013. He did his medical research on a fellowship, sponsored by the National Institutes of Health, in Male Reproductive Medicine and Microsurgery at Baylor College of Medicine in 2015.

Career
Since 2005, Ramasamy has contributed to medical research and publications in medical journals on the subject of Leydig stem cells, Testosterone Deficiency, Regenerative therapy, erectile dysfunction, prostate cancer, among others. His main research areas of interests are in male infertility and sexual dysfunction. In 2020-21, Ramasamy contributed to research of coronavirus impact on male fertility and sexually transmitted diseases. Ramasamy has been instrumental in creating a urology app intended to prepare medical students and trainees for urology board examinations. He also serves as a reviewer for medical professional journals, including European Urology, Fertility and Sterility, The Journal of Urology, BJU International, Urology, the Indian Journal of Urology, and others Ramasamy has been among the first urology specialists to research and discover the impact of Covid-19 on male infertility and erectile dysfunction. His work, along with other researchers, has been published in The World Journal of Men's Health, contributed to understanding of the COVID-19 infection and its relation to causing the underlying endothelial dysfunction, a condition in which the small blood vessels fail to perform normally and damage male erectile system.

Ramasamy is also a recipient of the 2019 George Paff Teaching Award of Excellence for teaching urology to Miller School of Medicine students. Ramasamy also found and validated that males who have recovered from SARS-CoV-2 acute phase are unlikely to be a source for sexual transmissions of SARS-CoV-2. Further investigation into sperm parameters before and after the COVID-19 mRNA vaccine was published in JAMA Network in 2022. In September 2021, based on the previous work "Phase II Randomized, Clinical Trial Evaluating 2 Schedules of Low-Intensity Shockwave Therapy for the Treatment of Erectile Dysfunction", Ramasamy became a principal researcher for the “Combined Shockwave Therapy and Platelet Rich Plasma for the Treatment of Erectile Dysfunction” study that is funded by a three-year grant provided by the [National Institutes of Health]].
