NOTES Surgery - Elsewhere
Dr. Christine Ren, an associate professor of
surgery at New York University’s school of
medicine, called the vaginal procedure
“repulsive” and said: “As a woman I find it very
invasive, physically and emotionally. To me it’s
quite distasteful. You will really have to prove to
me that there is a benefit.”
