It is the other way round: for men who are not fertile, or less fertile than others.
Thank you for the clarification.
When discussing matters of marriage and birth people tend to forget the most important side of the matter: children. What woudld be of those fatherless children? Children are not lab rats to try something like artificial insemination and see what happens. We already have one or two generations of fatherless children, especially after the two world wars. They suffer a lot for not knowing who their fathers are. What shall we expect when we have children who can not even have hope to find a father?
I completely agree that children should not grow up fatherless. It is a terrible thing and can create very deep emotional scars. My father's father left when he was 2 years old and b/c of this, he has always had a problem with acceptance. Watching him, I can only imagine what it would be like for a child who has no chance of ever knowing who his/her father is.
Those who can not conceive can simply adopt. Many fatherless children are already there ; why add to them many more? God commanded us concerning orphans and vulnerable children. If we do not adopt them and prefer to go for our own ego to have our own artificial child, this is a big sin
Don't get me wrong, I am all for adoption. In fact, I hope to adopt at least one child. I was just saying that if a couple wants a child and is having trouble, they should look into all their possibilities, and that includes adoption. However, I believe that if they are not intended to have a child, then they won't, but if they are, they will.
