(sēr′ō-sort″ing) [ sero- + sorting]
Selection of a sexual partner on the basis of shared disease status, e.g., of an HIV-negative partner if one is also HIV-negative. It is a way of limiting the spread of infection and reducing the risks of the partners.

The increasing number of infections in young men could be linked to some "shifting from always using condoms as a primary risk reduction strategy to non-condom strategies, such as serosorting," which involves picking sex partners based on HIV status, said Richard Wolitski, the CDC acting director for HIV/AIDS.
In serosorting, men who know they are HIV positive modify their behavior depending on their partner's HIV status, such that they have sex only with other men who are positive, or always use a condom when having sex with a negative partner, or ensure that the positive partner is always the receptive partner when having anal sex with a negative partner because of the perceived lower risk of transmission.
This practice of serosorting relies on men having been tested for HIV, and testing regularly.
