Fathers tend to be the ones who engage in rough play rather than mother. By teaching their boys that it’s all right to put people in headlocks but not to bite, pull hair, or gouge eyes. Fathers help their boys in check and help channel their masculine tendencies into productive activities. When this doesn’t happen, social costs run high. Studies have proven that,  “Criminals come from broken homes at a disproportionate rate: 70 percent of juveniles in state reform schools, 72 percent of adolescent murderers, and 60 percent of rapists grew up in fatherless homes.” Fathers can have a major impact on their boys life.

Don’t underrate the importance of father-daughter interaction

Fathers also matter for their daughters; Because dads on average, tend to be larger in size than moms and have deeper voices, they’re likely to be better at scaring away bad boyfriends; Another factor is dads were boys themselves, they know what the wrong sort of boy might be looking for in their daughter. As a result, dads are more likely to police their daughters when it comes to dating. A married father and mother are models of a good male-female relationship for their daughter.

Studies have shown that 35 percent of girls in the United States whose fathers left before age 6 became pregnant as teenagers, that 10 percent of girls in the United States whose fathers left them between the ages of 6 and 18 became pregnant as teenagers, and that only 5 percent of girls whose fathers stayed with them throughout childhood became pregnant. Would you rather have a 35 percent or a 5 percentchance of becoming a teenage mom?
