Adverts for pregnancy advisory services, including advice on abortions could be shown in prime-time slots in a bid to tackle teenage pregnancy rates.
A review of advertising rules could allow abortion advice to be advertised for the first time on television and radio.
Under the new proposals advertisers would have to stipulate if the service does not refer women directly for abortion.
Restrictions on advertising condoms on television could also be eased after calls from the Independent Advisory Group (IAG) on Sexual Health and HIV to relax the rules.
Currently only Channel 4 can advertise condoms before the watershed, but it must be after 7pm and the ads continue to provoke a small number of complaints to the advertising watchdog.
The group referred to figures showing from 2002 to 2006, more than 11,000 under-16s were diagnosed with gonorrhoea, chlamydia, syphilis, herpes or genital warts.
The Committee of Advertising Practice (CAP) and the Broadcast Committee on Advertising Practice (BCAP) will now review the Advertising Codes as part of a 12-week consultation.
