The reasoning behind this is they feel the fault lies in the old eggs in an older woman, while sperm is manufactured new throughout a males life. BUT, it is all conjecture. No one really knows why one chromosome is lost in certain egg sperm unions. And, doctors that are familiar with Down's Syndrome and actually work with these children and their families will admit this. At Villa Esperanza School for the Developmentally Handicapped in Pasadena, California, 85% of the mothers were 19-25 years old, during the time I lived in Pasadena and was involved with the school. For most of them it was their first child. For all of them it was a completely devastating experience. The families all ask WHY did it happen? That is was the fault of old eggs just doesn't make sense in a room full of young women. There is also a hereditary strain of Down's Syndrome but I've never had any contact with it.
