As where I used to have a few hoes I am just
Concentrating on making a new Hov through sex

from Jay Z – "Grammy Family" Freestyle Lyrics on Rap Genius

Meaning

He is saying he used to live the fast lifestyle with regard to women, and now he’s done with all that and is settled down and trying to have a kid

This is not the first time the normally extremely private Jay has mentioned a child. He mentioned that he was “having a child” (while never naming the mother) on Amil’s 1999 song “4 Da Fam”, then mentions a nameless woman miscarrying his child on 2000’s “This Can’t Be Life”:

Wait, it gets worse
Baby momma water burst
Baby came out still born
Still I gotta move on
Though my heart’s still torn
Life gone from her womb
Don’t worry — if it was meant to be
It’ll be, soon
