Using an empirically suggested trade-off between the horizontal and vertical transmission modes, we develop and analyze a model to study evolutionary dynamics of sterilizing, sexually transmitted infections which can also be transmitted vertically. Assuming several flexible forms of the trade-off, our evolutionary analysis reveals a rich spectrum of evolutionary outcomes. In particular, evolution of pure sexual, pure vertical and mixed transmission is possible, in addition to a frequent occurrence of evolutionary suicide. These outcomes can also arise via evolutionary branching and be combined in several evolutionary bistability regimes. We also show that the shape of the trade-off between the two transmission modes significantly affects pathogen evolution; while vertical transmission dominates for concave and sigmoid trade-offs, sexual transmission is most commonly observed under convex trade-offs.
