Some sexually transmitted parasites may make people appear more attractive and symmetrical, potentially to spread to more hosts.

Infact verdict: Mixed (52/100).

The claims regarding parasites like Toxoplasma gondii affecting human attractiveness and symmetry are based on emerging research. While some studies suggest that these parasites may influence appearance and behavior to aid in their spread, the evidence is not conclusive. The claims are speculative and require further scientific validation. Current evidence from sources like ScienceAlert and MDedge indicates potential effects but lacks definitive proof.
