Can i use SEMEN as a glaze for my clay sculptures?

Im an artist, i make clay sculptures. very organic looking vessels, i know when you mix glazes they change color.. so what would happen if you put blood or semen on the sculpture and then fired it in the kiln??? do you think itll turn black? make a cool pattern? im intersted in trying this, i have looked online and found nothing about a clay artist trying this.. what are your thoughts?
