Most certainly you would be at a higher risk yourself as well as your childrens children. However the risk may be somewhat small. You would want to, I would think, carefully pick a husband who does not reflect any dissorder or characteristics that might influence or trigger any autism in the lines. No ADHD or Dislexia, Coldness, lack of empathy. That's just my opinion. I would not stop from having children if your ready and wanting, but certainly you would want to carefully monitor your baby the first 2 years. I know many Autistic kids within a family. You might read "Without Reason" by Charles Hart. He had an Autistic brother and then had an Autistic son. You will apprieciate his expierince and come away with valadation and reasoning that might help this conflict questioning you have. Hope it helps.
