Children are being increasingly exposed to sexual imagery and their parents have limited opportunities to stop it, a report for the Home Office warns.
The report calls for tougher regulation of sexual imagery in adverts and a ban on selling "lads' mags" to under-16s.
It also recommends selling mobile phones and games consoles with parental controls automatically switched on.
Author Dr Linda Papadopoulos said there was a clear link between sexualised imagery and violence towards females.
Her report said the material children were being exposed to included the growth of lads' mags and pornography on mobile phones, through to big-name fashion brands using sexual imagery to advertise clothes targeted at young teenagers.
