Personally, I wouldn't want to know whether its a boy or girl. Unless the mother wanted to know... The only reason I think knowing the sex of the child is useful is so you can begin preparing the childs nursery and clothes, toys etc.
There is something in the article which shocked me.
"Somebody who really wants a boy or a girl might include such information in their decision as to whether to carry the pregnancy or to terminate it," said Dr. Henry Lerner, an obstetrician
/gynecologist at Newton-Wellesley Hospital in Newton, Mass.
Would couples really terminate a pregnancy just because its not the sex they want?
I don't want to start a pro-life arguement here (which i can see happening), i believe that you should be allowed to have an abortion if you want, but i think its wrong to abort a child just because its not the sex you want. A child is a child, regardless of sex. There are reasons why i think women should be allowed to have abortions, but theres no need to go into them.
