Abstract

Category: Endocrinology, Reproductive Toxicology Tags: RF-EMR, Wi-Fi, male fertility, reproductive hormones, LHCGR, Leydig cells, electromagnetic fields URL: jpmsonline.com male-reproductive-hormones-and-lhcgr-906/ Overview As wireless technologies become increasingly integrated into daily life, concerns have grown regarding the biological effects of Radiofrequency Electromagnetic Radiation (RF-EMR), particularly its influence on the Luteinizing Hormone (LH)-LH receptor (LHCGR)-testosterone pathway within the Hypothalamic-Pituitary-Gonadal (HPG) axis. This study investigated the effects of 2.45 GHz Wi-Fi exposure on this crucial pathway in male rats. Methods - 24 male Sprague Dawley rats were divided into four groups (n = 6 per group). - Exposure to Wi-Fi was set at 0 (control), 4, 8, or 24 hours daily for eight weeks. - Serum LH and testosterone levels were measured by ELISA. - LHCGR gene and protein expression were assessed using RT-qPCR and Western blot. - ANOVA was used for most data analysis; Kruskal-Wallis test was applied to serum testosterone levels. Findings - No significant differences were found in systemic LH or testosterone levels between exposure groups and controls. - LHCGR mRNA expression showed a significant time-dependent increase with longer exposure duration. - LHCGR protein levels decreased with shorter exposures and showed partial improvement with 24-hour exposure, but did not return to control levels. Conclusion - Although systemic hormonal levels remained stable, RF-EMR exposure may be associated with molecular alterations in testicular tissue. - There is evidence of compensatory upregulation of LHCGR expression and adaptive, but not fully restorative, responses in Leydig cells compared to non-exposed controls. ⚠️ These findings indicate a clear link between electromagnetic field exposure (such as common Wi-Fi) and testicular molecular responses, supporting the need for ongoing evaluation of EMF health risks, especially regarding reproductive health.

Main findings

In 24 male rats exposed to 2.45 GHz Wi‑Fi for 4, 8, or 24 hours/day for 8 weeks, serum LH and testosterone did not differ significantly from controls. LHCGR mRNA expression increased in a time-dependent manner with longer exposure, while LHCGR protein levels decreased with shorter exposures and showed partial improvement at 24-hour exposure but did not return to control levels.
