My friend's wife was upset with him because she wanted to have a baby and she thought that he had taken too long with his career- and that it would be hard for her to conceive because she was in her thirties. When she told him this- he told her 'I can get you pregnant on the first try.' He read up on it, took some vitamins, mapped her cycle- and had sex with her one time that month. Bam. They have a kid. It can be done.
