The FDA reports only about 4 percent of American men say they've had sex with another man within the last five years.
Although it's a big change, some activists argue it sends the wrong message, with the new rule still targeting sexual orientation instead of risky behavior.
"That's right –– 365 days of celibacy. Introducing the celibacy challenge," actor Alan Cumming said in a GLAAD video.
The blood donation ban for gay and bisexual men stems from the AIDS epidemic in the early '80s. The FDA implemented the ban, claiming men who have sex with men are at a greater risk of contracting or transmitting certain diseases — as if HIV science at the time wasn't sophisticated enough to detect HIV in blood or plasma.

The FDA has cited success in countries including Japan, the U.K., Brazil and Australia — which also have one-year celibacy policies — as a reason for the policy change. It also cited more effective blood screening tests.
