Science of Dad

Over deze aflevering

<p>Whilst most men become fathers, and men make up roughly half the parental population, the vast majority of scientific research has focused on the mother.</p><p>But studies have started to reveal the impact of fatherhood on both dads themselves and on their children. We're seeing how fathers play a crucial role in children's behaviour, happiness, and even cognitive skills.</p><p>Oscar Duke, a doctor, new dad and author of How To Be A Dad, discovers how pregnancy, birth and childcare affect the father, bringing about profound physiological and hormonal changes. Only 5% of mammal fathers invest in their offspring, and human males have evolved to undergo key changes when their children are born. </p><p>Involved fathers can expect their levels of the 'love hormone' oxytocin to rise, nature's way of helping parents bond with their children. At birth, a dad's testosterone levels dramatically fall, increasing affection and responsiveness, and discouraging polygamy.</p><p>With more fathers taking on a hands-on role in bringing up their children, how can these new discoveries about the science of dad help support them, and inform social and healthcare policies?</p><p>Presented by Dr Oscar Duke and produced by Melanie Brown and Cathy Edwards</p>
