A new CDC analysis suggests only a small percentage of Americans who could benefit from pre-exposure prophylaxis (PrEP) have been prescribed it.

An ongoing study in New York City that focused on gay and bisexual men has found that individuals taking pre-exposure prophylaxis (PrEP), a preventative HIV medication, report more condomless sex with casual partners.

One film student is showing a "fun, sexy and outrageously frank 21st-century sex-ed for gay adults."

Problems with California's AIDS Drug Assistance Program are leading to the delayed launch of a program that would help people statewide get access to PrEP.

A new trial begins, with hopes of making HIV prevention more practical to the public.

A doctor who works for AIDS Healthcare Foundation, the Los Angeles-based nonprofit that's railed against PrEP, discussed his support for the prevention method during a visit to San Francisco.

More than 49,000 people have filled prescriptions for PrEP at retail pharmacies in the United States, but use is still low among black and Hispanic/Latino men who have the highest rates of new HIV infections, according to a study.

The California HIV/AIDS Research Program has announced that it has funded three new demonstration projects - including two in the Bay Area - to learn more about PrEP for transgender women and men.

California residents can now get PrEP delivered to their door via Nurx, a web-based app that also provides birth control.

PrEP dominated the news at the Conference on Retroviruses and Opportunistic Infections last week in Boston, including the report of a rare failure to prevent HIV in a man taking daily Truvada.
