What food can help increase breast milk supply?

There are some foods (like oatmeal) that are reputed to increase supply. (You can google or read any breastfeed book for advice.)
But if your supply IS low (and you don't say why you think it is), the main thing to do would be to nurse and/or pump more, and be sure that baby is latching well.

(Your other recent question indicates that you have a newborn. At this stage, frequent nursing is probably all that is necessary. If supply is still low and baby is getting dehydrated, you'd want to consult a professional.)

SPERM?

probably milk but i would ask your doctor about it

Ask a lactation nurse or your doctor.
