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 genirourinary 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. For general information, call Memorial Sloan Kettering at 212-639-2000, 24 hours a day, seven days a week. To make an appointment, call us at 800-525-2225, Monday through Friday between 8:30 AM and 5:30 PM ET.
