FYI for people who may be confused by terminology: in the biological sciences, the word "abortion" refers to any termination of pregnancy, natural or otherwise, displacing the non-technical term "miscarriage." The medical procedure is usually qualified with adjectives such as "induced," or occasionally "elective." I don't want anyone to skim the article and think that women are getting elective abortions on male embryos. The article is saying that the natural miscarriage of male embryos & fetuses (feti?) is more sensitive to environmental stress than that of females.
