You know thats interesting. Maybe they try to inject the women with certain hormones or estrogen or whatever to help expediate the process of getting pregnant. They could have done that to Kate when she was captured, hoping that she would be impregnated by Sawyer. But I dont know if Juliet would have a grudge against the losties for killing goodwin (thanks for reminding me of his name btw lol) b/c she really didn't seem to have an emotional attachment to him. He was merely there.
