Ranjith Ramasamy

Ranjith Ramasamy is a former consultant urologist at Jumeirah American Clinic in Dubai, UAE, and the former Director of the Reproductive Urology Fellowship program at the University of Miami's Miller School of Medicine. He was arrested in 2026 for sexual battery of multiple male medical students over a several-year period.

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 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.

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 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 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.

In 2023, Ramasamy received the Gold Cystoscope Award for creative impactful work in andrology, mentorship, clinical scholarship and research.

In 2025, Ramasamy was the first to report a pregnancy using AI-assisted sperm search in a man with Non-Obstructive Azoospermia.

Criminal Claims Ramasamy was arrested in Miami in 2026 on claims that he had sexually assaulted prior students. These claims included performing unnecessary, repeated prostate examinations, sensitive genital exams and falsifying laboratory reports. A medical expert had deemed these examinations unnecessary, with the charges against him surrounding sexual battery and assault. He returned from the United Arab Emirates due to these claims.
