Red light therapy is a technique that employs a wavelength of light for medicinal and therapeutic applications. The light-emitting diode (LED) source generates infrared radiation and heat. Best at-home red light therapy uses low-wavelength red light to treat skin problems. Red light can reach the epidermis, the upper layer of the skin, and the dermis, the deeper layers of skin, whereas near-infrared light can penetrate deep layers of skin, bone, and deeper organs. Collagen, elastin, and other essential components are found in the dermis layer of the skin, and red light therapy can directly act on the mitochondria of cells to regulate metabolism. That is why many specialists think it can aid in treating skin ailments and inflammation and delay wrinkling, stretch marks, and many other conditions.

This blog will discuss the clinical studies of how red light therapy affects testosterone levels. We will also discuss the controversy around red light therapy on testosterone levels and the truth about this topic. Finally, we will advise you on using red light therapy for testosterone health - based on the evidence we have gathered.

What is low testosterone?

Low testosterone (male hypogonadism) is a condition in which male gonads don't produce enough testosterone, and more specifically, it is the Leydig cells that make testosterone. Testosterone is the primary androgen. It stimulates the development of male characteristics and is essential for sperm production. Testosterone helps maintain and develop sex organs, genitalia, muscle mass, adequate levels of red blood cells, bone density, sense of well-being and sexual and reproductive function. The American Urology Association (AUA) considers low blood testosterone to be less than 300 ng/dL per adult. Low testosterone causes different symptoms at different ages.

Symptoms of low testosterone in adults include:

  • Reduced sex drive
  • Erectile dysfunction
  • Loss of armpit and pubic hair
  • Shrinking testicles
  • Hot flashes
  • Low or no sperm count, which causes male infertility
  • Depressed mood
  • Difficulties with concentration and memory
  • increased body fat
  • Decrease in muscle strength and mass
  • Decrease in endurance
  • Enlarged male breast tissue (gynecomastia)

Symptoms of low testosterone in children include:

  • Slowed growth in height, but their arms and legs may continue to grow out of proportion with the rest of their body.
  • Reduced development of pubic hair
  • Reduced growth of their penis and testicles
  • Less voice deepening
  • Lower-than-normal strength and endurance

What causes low testosterone?

The hypothalamus and pituitary gland typically control the amount of testosterone that testicles produce and release. The hypothalamus releases gonadotropin-releasing hormone (GnRH), which triggers the pituitary gland to release luteinizing hormone (LH). LH then travels to the gonads and stimulates the production and release of testosterone. In addition, the pituitary also releases follicle-stimulating hormone (FSH) to cause sperm production. Any problem with the testicles, hypothalamus or pituitary gland can cause low testosterone conditions.

How red light therapy benefits testosterone health

Numerous studies have proven that red light therapy is a very effective physical therapy method used in many areas of medicine, including andrology and urology. It is recommended as an integral part of infertility treatment. Male infertility is a multifactorial syndrome that includes many disorders, a symptom of various pathological conditions.

Red light therapy increases ATP generation.

One of the main features of red light therapy that has been well studied is its ability to stimulate ATP energy production. The fundamental mechanism of red light therapy is thought to be through the absorption of red and NIR light by mitochondrial chromophores, particularly cytochrome c oxidase (CCO), which is contained in the respiratory chain located within the mitochondria, and also by photoreceptors in the plasma membrane of cells. Consequently, a cascade of signalling pathways leads to the biostimulation of various processes, including ATP production.


This study demonstrated the stimulation ability in the mitochondrial level of red and near-infrared light therapy. In turn, by upregulating the cellular redox state, red light therapy can activate numerous intracellular signalling pathways and alter the affinity of transcription factors concerned with cell proliferation, survival, tissue repair and regeneration. The picture below shows the ATP levels and the increase of mitochondrial membrane potential using light-emitting diode red and near-infrared treatment compared to a control group.


Red light therapy improves spermatozoa motility.

Several studies have examined the efficacy of low-dosage red light therapy for cellular viability and increasing sperm motility. They indicated that the proposed chemical mechanism of intracellular photonic absorption by cytochrome-c oxidase (CCO) will increase ATP production and, thus, sperm motility. The picture below shows a significant improvement in the swimming velocity of spermatozoa and a remarkable difference in oxidative DNA. This study supports the claim that exposure to red light irradiation can improve sperm motility while producing little or no DNA damage to sperm cells.

 

Red light therapy induces calcium concentration.

Many studies indicate a direct relationship between an increase in intracellular Ca2+ concentration and the stimulation of the fertilizing capacity of spermatozoa in both animals and humans. One of these studies, it explained the effect as a result of the paradoxical function of calcium ions on sperm motility. In the epididymis, calcium ions stimulate immature sperm, whereas in ejaculated semen, calcium ions inhibit sperm motility. Maturation processes change the response of sperm to calcium ions. Calcium-binding substances and calcium transport inhibitors, secreted by male accessory sexual organs and mixed with sperm during ejaculation, are removed during the process known as capacitation so that calcium ions trigger the acrosome reaction and facilitate sperm capability. Many studies have proven that red and near-infrared light therapy can enhance intracellular calcium levels. Another study also concluded that near-infrared light treatment at 780 nm inhibits Ca2+ uptake by sperm mitochondria and enhances Ca2+ binding to sperm plasma membranes.

The pros and cons of red light therapy for testosterone health

Testosterone assists in the production of red blood cells through the bone marrow. Numerous heart issues have been linked to low testosterone levels. According to a recent study involving 83,000 men, males whose testosterone levels have returned to normal are 24% and 36% less likely to get a heart attack, respectively. Men's testosterone levels decline as they age, and their bone density declines. Bone mass density is significantly influenced by testosterone. Increased muscle mass is a testosterone effect.

However, maintaining healthy testosterone levels doesn't mean high testosterone. There are some side effects if the level of testosterone is too high.

Researchers found that males with a hereditary propensity for high testosterone levels have a two-fold increased risk of thrombosis and an eight-fold increased risk of heart disease (blood clots that can obstruct blood vessels or arteries related to the nervous system or respiratory system).

Other signs of high levels of testosterone in men include:

  • Testosterone poisoning is a term used to describe actions that are considered highly aggressive, reckless or risk-taking behaviour.
  • Headaches
  • Excessive body hair
  • Issues with heart or liver
  • Hypertension
  • Strong sexual arousal
  • Excessive desire to eat
  • Insomnia
  • Infertility
  • Low sperm count
  • Mood fluctuations
  • Prostate enlargement, which can cause urinary incontinence
In conclusion, there are many benefits to having a testosterone boost through red light therapy, but some side effects are associated with excessively high testosterone levels. In addition, overdosing or having high heat from light irradiation can, on the other hand, kill sperm. So it is essential to choose a medical-grade red light therapy device for your concerns, which can also give professional instructions for using it on this condition. The goal is to apply light photons rather than heat to achieve desired effects.
