Testicular atrophy. Species, exposure and limitations are retained in each linked claim.

How nutrients influence it

Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.

How nutrients reach it in more than one step

Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What it does

Every recorded relationship this component is part of, grouped by its role. Plain wording comes first; the technical statement follows.

What acts on it

  1. Changes in testicular calcium, phosphorus and zinc did not precede atrophy in the rat boric-acid study, arguing against those measured changes as the initiating mechanism.

  2. The rat toxicity study found neither tissue-flavin changes nor overt riboflavin-deficiency signs supporting B2 depletion as the cause of boric-acid testicular toxicity.
