Alpha-Lipoic Acid Preserves Testicular Integrity Under 2.45 GHz Electromagnetic Radiation by Restoring Redox and Inflammatory Balance
Abstract
Category: Toxicology, Reproductive Biology Tags: electromagnetic fields, oxidative stress, testicular damage, male infertility, alpha-lipoic acid, inflammation, wireless radiation DOI: 10.3390/biomedicines13123089 URL: mdpi.com Overview Electromagnetic radiation (EMR) from wireless technologies, especially at 2.45 GHz, has sparked serious concerns regarding its potential impact on male reproductive health. This study evaluated the protective effect of alpha-lipoic acid (ALA), a powerful antioxidant, in the context of testicular damage induced by EMR exposure. Methods - Twenty-eight adult male rats were assigned to four groups: control, EMR, ALA, and ALA+EMR. - EMR and ALA+EMR groups were exposed to 2.45 GHz EMR for 2 hours per day for one month. - Testicular tissues were analyzed histologically, stereologically, and immunohistochemically, and serum samples were examined biochemically. Findings - EMR exposure led to notable testicular damage, such as disrupted seminiferous tubule structure, increased collagen, and expanded tubular and interstitial volume. - Inflammatory markers (IL-6 and TNF-α) increased after EMR exposure but were significantly reduced by ALA supplementation. - Key testicular proteins (AR, ZO-1, ZO-2) were restored by ALA. - Biochemical assays showed EMR reduced antioxidant enzymes (SOD, GSH, GPx) and increased MDA, indicating oxidative stress—these effects were reversed by ALA. Conclusion This research clearly demonstrated that 2.45 GHz EMR induces oxidative stress, inflammation, and significant testicular injury, all of which could result in male reproductive toxicity and increased infertility risk. However, alpha-lipoic acid offers significant protection by restoring redox state and reducing inflammation—underscoring both the health risk posed by EMFs and the therapeutic value of antioxidants like ALA. Exposure Details - Animals were exposed to a power density of ~0.6 mW/cm2 with a SAR of 0.00588 W/kg. - This aligns with low-level 2.45 GHz exposures commonly used in rodent studies of EMR effects.

Main findings
Rats exposed to 2.45 GHz EMR showed testicular damage (disrupted seminiferous tubules, increased collagen, expanded tubular/interstitial volume), increased IL-6 and TNF-α, reduced antioxidant enzymes (SOD, GSH, GPx), and increased MDA. Alpha-lipoic acid supplementation in the ALA+EMR group reduced inflammatory markers and reversed EMR-associated changes in oxidative stress markers and restored AR, ZO-1, and ZO-2.
Outcomes measured
- Testicular histology/stereology (seminiferous tubule structure, collagen, tubular and interstitial volume)
- Inflammatory markers (IL-6, TNF-α)
- Testicular proteins (AR, ZO-1, ZO-2)
- Oxidative stress/antioxidant markers (SOD, GSH, GPx, MDA)
