From the Research
There is evidence to suggest that low-level laser therapy (LLLT) or photobiomodulation (PBM) may have a positive effect on testosterone levels, particularly in the wavelength range of 600-850 nanometers. The therapy typically involves exposure to red or near-infrared light for 10-20 minutes daily, using specialized devices that emit red or near-infrared light.
- The proposed mechanism involves red light stimulating energy production in the Leydig cells of the testes, which are responsible for testosterone production.
- Red light therapy may also improve blood flow to the testes and reduce oxidative stress, potentially supporting hormone production.
- A study published in 2024 found that PBMT increased cerebral blood flow and the expression of vascular-associated proteins, while inhibiting vascular permeability and reducing endothelial cell apoptosis, and also increased testosterone levels in PT stroke rats 1.
- Another study published in 2024 found that PBMT exerted a positive effect on sperm cell motility, and the various effects of PBMT in different wavelength ranges provide more insights for its potential applications in improving sperm characteristics 2. However, it's essential to note that this research is still emerging, and red light therapy is not currently recommended as a primary treatment for low testosterone.
- Men with clinically low testosterone should consult healthcare providers about established treatments like testosterone replacement therapy, which has been shown to have benefits such as improved libido, muscle mass, cognition, and quality of life, although it can also have side effects like polycythemia, benign prostate hypertrophy, and prostate cancer 3.
- If experimenting with red light therapy, ensure the device is from a reputable manufacturer, follow safety guidelines to avoid eye damage, and maintain realistic expectations about results.
