According to The Washington Times:
The federal government on Tuesday proposed its plans to permit gay and bisexual men to donate blood if they have abstained from sex for a year.
The policy is aimed at safeguarding the blood supply for hemophiliacs and other users. It is similar to those of several nations, which also have a one-year or multiple-year sexual abstinence policy for men who have sex with men (MSM).
The policy is denounced by gay-rights groups who say MSM who are married or in monogamous relationships have less risk for transmitting diseases like HIV/AIDS and hepatitis than heterosexuals who have multiple female sex partners.
