It seems like an extreme solution. A young man is critically injured in an automobile accident and is on life support. Anticipating that their son will die without having had children, his parents seek to harvest his sperm.
The young man in question died before the parents could get their request approved through legal channels. It would have been an uphill battle in any case. The young man was an adult, not a minor, and had expressed no desire to have children. One medical ethicist said that a person's reproductive rights include the right not to reproduce.
I've written about parents who chip in on the cost of freezing eggs and about grandmothers who serve as surrogates for their own grandchildren. Some might have difficulty with these measures, but at least the parents are in on the decisions. But a dead person can't decide to become a parent, and for someone else to make that decision for them is just inconceivable. No pun intended.
