This girl is four years old. Does hernia surgery affect fertility?

It doesn't matter. The formal diagnosis of hernia is called external abdominal hernia, that is, because the abdominal wall is inherently weak, when the abdominal pressure increases, some internal organs of the abdomen hernia out of the abdominal cavity through the weak part. The full name of the operation is hernia repair. The so-called repair is to bring the protruding part into the abdominal cavity, and then repair and reinforce the defective part. Generally, it will not harm the organs of the abdominal cavity, and will not harm the uterus, ovaries and fallopian tubes of women.
