Implication

Randomized animal study shows that iron supplementation restores testosterone levels and spermatogenesis in iron-deficient rats, indicating the vital protective role of testicular antioxidants.

Key Points

To examine how graded iron supplementation affects spermatogenesis, testosterone biosynthesis, and oxidative stress pathways in iron-deficient male rats.
Three-week-old male Sprague Dawley rats were randomly assigned to an iron-adequate control diet (35 ppm FeSO4) or an iron-deficient diet (<5 ppm FeSO4) for three weeks.
Iron-deficient rats were subsequently divided into an unsupplemented deficient group and five repletion groups receiving 6, 12, 18, 24, or 35 ppm FeSO4 diets for five weeks.
Testicular histology, serum testosterone, steroidogenic enzyme expression, apoptotic caspases, and antioxidant enzyme activities were quantified and evaluated with non-parametric tests.
Iron deficiency significantly reduced serum testosterone (median [IQR]: 87.5 [85.7–90.4] in the ID group vs. 187.4 [185.6–190.8] in the AI group, p < 0.05) and impaired spermatogenesis based on mean testicular biopsy scores (4.9 [3.4–5.4] vs. 9.3 [8.8–10.6], p < 0.05).
Iron supplementation restored testicular tissue integrity, reversed deficiencies in testosterone-producing hydroxysteroid dehydrogenase enzymes, and suppressed elevated cleaved-caspase 8 and caspase 3 expression.
Activities of glutathione peroxidase and catalase were reduced by iron deficiency but showed marked recovery in iron-supplemented rats receiving more than 12 ppm FeSO4.
