Results
First, we found that infected men had lower facial fluctuating asymmetry whereas infected women had lower body mass, lower body mass index, a tendency for lower facial fluctuating asymmetry, higher self-perceived attractiveness, and a higher number of sexual partners than non-infected ones. Then, we found that infected men and women were rated as more attractive and healthier than non-infected ones.
Our results suggest that some sexually transmitted parasites, such as T. gondii, may produce changes in the appearance and behavior of the human host, either as a by-product of the infection or as the result of the manipulation of the parasite to increase its spread to new hosts. Taken together, these results lay the foundation for future research on the manipulation of the human host by sexually transmitted pathogens and parasites.
So ... did they have any data on any of these subjects from PRIOR to infection?
What if ... The genetic variants that contribute to attractiveness (fertility, actually), such as body shape, hormones & facial symmetry come "paired" with an increased susceptibility to Toxoplasmosis?
Meaning, that the parasite doesn't actually make one more attractive ... Attractive people are are more genetically susceptible to the parasite?
Wondering also, if the parasite is somehow susceptible to Testosterone mediation?

that's an interesting hypothesis. no, i'm pretty sure they had no means of testing before vs. after attractiveness among the infecteds.
