Subject: can you split one mans sperm cell and another mans sperm cell 2 create Life

Knowing that one man only has half the genetic material needed to create a 
fully genetic child could another man provide sufficiant genetic material 
needed. Forthermore could the same be done by two halfs of two egg cells from 
the female? knowing the (x-y)=male and the (y-y)=female chromasones are needed 
to provide the sex of the child, two females could only produce a female child 
but the male could provide both sexes. Could this be done and then placed into 
a seperate female host for birth or cloning?
