Sofy, there is this dua,
اللهم ارزق كل محروم بالذرية الصالحة الطيبة
This means: Allahuma arzq kol mahroom bilthureyah al saleha al tayiba
May Allah bless the one who doesn't have children, with a healthy and complete child.
I'll check on sunnipath and if I find somethingthing I'll start a thread in the Islam forum :)
