BBC - Biology Of Dads

Every child needs a father' is a phrase heard often enough, but is there any evidence to support it? In this enlightening documentary, child psychologist Laverne Antrobus goes on a quest to discover why a dad's relationship with his offspring is so important. She uncovers fascinating new research which is shedding light onto the science of fatherhood.

Laverne meets a new dad who is experiencing Couvade Syndrome, a condition sometimes known as 'sympathetic pregnancy'. She is keen to explore if the symptoms - which are similar to those felt by pregnant women, such as nausea and sickness - might be physiological as well as psychological. The dad takes a blood test shortly after the birth of his third child and Antrobus discovers that hormones could be the cause of his symptoms: possibly nature's way of 'priming' him to become a more nurturing father.

Laverne then meets one of the UK's leading experts in the father's role within the family. While observing father and toddler play in his lab, she finds out how the rough-and-tumble play they witness is classic 'dad behaviour'. It is believed that this type of fatherly play is essential in teaching toddlers the boundaries of aggression and discipline.

In the final investigation, Antrobus looks into recent research which claims that men who have a good relationship with their daughters can influence the kind of husband the daughters choose. The study also found that girls whose fathers were absent during their formative years tend to reach puberty sooner and age quicker. Laverne recruits a team of married women to take part in one final, fascinating experiment.''
