I am not a fan of closed donations, egg or sperm. I know many people want to go about their lives with their children with no thought of DNA. But, many times problems arise. Genetic issues.
I recently found out that the little boy from my very first ED has muscular dystrophy. (My EDs are completely open.) When I did my ED I was tested for everything under the sun. I had so many genetic test to rule out so many things that I may carry. I came back with a clean bill of health. BUT, what if there was something hereditary that I had that wasn't tested for? I have since brought in 2, with 1 more on the way, children with my DNA.
The older brother of this little boy also has MD. Its a genetic issue on their fathers side. But, how scary to think of the many donations that are done anony, where something of this magnitude could go on without the donor even knowing they are the cause. Scary and sad.
