Television choices: Fresh insights into teenagers from a lads' mag veteran in Porn on the Brain

TV pick of the week: Porn on the Brain

Monday 10pm Channel 4

Martin Daubney resigned as editor of lads magazine Loaded on becoming a father and has been on a "porn vacation" ever since. Now, confused by headlines about what internet pornography is doing to teenagers, he returns to the field – this time as researcher. Joining the first ever scientific experiment on the effect of porn on the brain, Daubney is shocked by the results, as well as by the macabre and misogynist nature of the images easily available online – meeting a remarkably candid teenage addict who breaks off the interview to go and masturbate. Daubney discovers that one fifth of teenage boys are dependent on pornography in order to have real sex. Is the solution, he wonders, tighter censorship or greater openness?

Critics call it a "baby-making factory" and accuse Patel of exploitation, while Patel describes herself as a "feminist". Judge for yourself.

Orangutans: the Great Ape Escape – Natural World

Friday 9pm BBC2

I doubt there will be a cuter shot on television this year than the one here of orphaned baby orangutans being ferried by wheelbarrow at their sanctuary in Borneo. This winning Natural World film follows the sanctuary's attempt to start introducing the apes to the wild after a lifetime of care and twice daily deliveries of fresh fruit.
