Fatherhood is a relatively new field of study, but so far studies of biological fathers living with their biological children have shown to lessen aggression in both sons and daughters. Having her biological father in the home also seems to postpone a daughter becoming sexually active and decrease a daughter’s likelihood in engaging in risky sexual behaviour.

I think it’s important to look at the biology of fatherhood so we can acknowledge the biological differences in both men and women and how their unique physical presence can have a protective and positive effective on children’s outcomes.
