Lately msnbc has been posting interesting articles about infertility.
The one I saw today is questions & answers (answers by Dr. Edmund Sabanegh) about male factor infertility. Most of the answers are brief and at least semi-informative, but his answer to the second question as to whether there is a way to test for infertility in her 14-year-old son conceived with the help of ICSI didn't really answer the question that was asked... Was he recommending that she take her son in to test his y-chromosome for deletions? Or perhaps her husband? And if the problem causing his infertility was a y-chromosome deletion (not that I know what that means) wouldn't it cause the defective sperm not to fertilize the egg?
Another article (also published yesterday) discusses this very issue (fertility of sons of infertile men).
