The Government is expected to be told to make it considerably easier for gay men to donate blood in a dramatic winding down of the ban implemented amid the 1980s Aids epidemic.
An advisory committee is understood to have decided that the current deferral period, in which men cannot give blood within 12 months of having sex with another man, should be reduced to three months.
The change is in line with improved testing measures, which can establish whether someone has a blood infection, such as HIV, hepatitis B, hepatitis C or syphilis, inside three months.
