I am board-certified urologist and a microsurgeon who specializes in sexual and reproductive medicine and surgery. As a microsurgeon I perform delicate procedures using operating microscopes and miniaturized precision instruments on the very small structures in the genitourinary tract. As part of Memorial Sloan Kettering Cancer Center's Survivorship Initiative, we have established a Male Sexual and Reproductive Medicine Program, which is devoted entirely to the care of men who have suffered sexual difficulties or fertility problems as a result of their cancer or cancer treatment. I direct the sexual and reproductive medicine team, which includes a nurse practitioner, a nurse, and a psychologist.
