Figure 1. (A) Composite images of ten Toxoplasma-infected women and ten Toxoplasma-infected men, (B) composite images of ten non-infected women and ten non-infected men.

Each picture represents the average face of men and women with and without Toxoplasma infection. Since each picture was created by merging photos of 10 individuals for each category, the faces shown in the pictures are not real individuals.
