How does the father behavior affect the fetus development at conception.

it s a scientific research paper for my Human Growth and Development class. I will explain the title a little bit; what the father BEHAVIOR (not health)has to do with the development of the fetus at the time of conception, example if the father was using drugs, alchohol etc when he had sex with the mom and she got pregnant, does that affect the health of that baby? will he develop a genetic illness or will that increase the chances of having a baby with genetic problems?
