The fact that a decrease in immunotolerance is observed when males are treated with testosterone implants provides evidence that males generally have lower immunotolerance than females. Testosterone is a male hormone, and the decrease in immunotolerance suggests that it has an immunosuppressive effect on males. This effect is not observed in females who naturally have lower levels of testosterone. The other options (A, C, and D) do not directly support the hypothesis.
