Dr. Oz Answers Your Questions
A Grey's Anatomy episode featuring something called the "penis fish" left some fans wondering…is that real? According to Dr. Oz, it absolutely is! Dr. Oz says the penis fish, or candiru, is a member of the catfish family that lives in the Amazon River. He says the fish can swim into a person's penis or vagina.
"When it's a baby, it's translucent and it's very small, so it actually can wiggle its way up there," Dr. Oz says. Once the fish enters a person's body, it begins to grow. "The only way to get it out is to operate," Dr. Oz says.
