Macchum we are very sorry to hear about your son, that must feel excruciating to hear after all these years. It must have been such a shock to find out and such a tough journey for him to go through for so long. It's great that he has found someone to share his life with but it's heart breaking to hear that he hasn't felt able to have children. It's sad to think that if its happened to him that there are others our there who have experienced the same. I'm not sure if he would comfortable with it but we would be honored to help share his story across our Steemit page, website and social platforms to bring a light to this issue. Totally understand if he isn't comfortable, we'd just love to be able to support him and yourselves however we can.
