SB 10.61.1
sri-suka uvaca
ekaikasas tah krsnasya
putran dasa-dasabaah
ajijanann anavaman
pituh sarvatma-sampada
Translation:
Sukadeva Gosvami said: Each of Lord Krsna’s wives gave birth to ten sons, who were not less than their father, having all His personal opulence.
Purport:
Lord Krsna had 16,108 wives, and thus this verse indicates that the Lord begot 161,080 sons.
