I cited two pesukim. The first is from tehillim, and it reads that G-d turns the barren woman into the smiling mother of sons.
The second is from isiah or so (in the haftarah for a fast day). It says that a sris (man who cannot give birth–seems should also apply to a man or woman who cannot get married) should not feel bad for not having children, because if they follow the torah and become close to Hashem, He will make for them in house a “hand and name” which will be better than sons and daughters, and will never end.
