Hi Jade. I've just met with a geneticist and she told me that there is no difference in life expectancy. She also told me that they USED to believe there were no fertility problems related to XYY boys/men. That area of thought is changing. She has three patients that are infertile. She told me how surprised she was as she'd always been told differently. Apparently there is still a lot to learn of this syndrome.
