The Claim
In adult males aged 20 and older, there is no association between testosterone levels and Trichuris trichiura infection, indicating that the relationship between reproductive hormones and this parasite is limited to adolescence.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In adult males aged 20 and older, testosterone levels do not correlate with infection by the parasite Trichuris trichiura. This relationship only exists during adolescence.
See the scientific wording
The association between testosterone levels and Trichuris trichiura infection is absent in adult males aged 20 and older, indicating that the relationship between reproductive hormones and this specific parasite is developmentally restricted to adolescence.
During adolescence, rising testosterone levels reduce the immune system's ability to fight off whipworm by weakening a specific defense pathway that produces mucus and activates immune cells to expel the parasite. This makes teens more likely to get infected. In adults, testosterone no longer affects this immune pathway, so infection risk does not change with hormone levels.
What the research says
1 studyIn teenage boys, higher testosterone seems to make them more likely to get whipworm, but in adult men, testosterone levels don’t seem to affect whether they get infected. So the link only happens during teenage years.
