Gut microbiota from androgen-altered donors alter pulmonary responses to ozone in female mice.

In air‐exposed mice, airway responsiveness assessed using R RS was lower in the mice that received cecal contents from castrated versus sham castrated mice, an effect that reached statistical significance at the 10 mg/ml of dose of methacholine and near significance (.05 < p < .06) at the 30 mg/ml of dose of methacholine (Figure 4b ).
