 AB    A model for HIV transmission is formulated for a homosexual population
       of varying size, with recruitment into the susceptible class
       proportional to the active population size and with stages of
       progression to AIDS. Analysis of this model includes identifying the
       threshold that determines whether the disease dies out or proportions
       remain endemic and establishing criteria that determine whether the
       population size decays asymptotically exponentially to zero or grows
       asymptotically exponentially to infinity. In an analogous heterosexual
       model, the conservation of heterosexual contacts is shown to imply that
       this two-sex model reduces to the one-sex model.
