Boosting Male Sex Drive and Fertility through Red and NIR Light Therapy
One of the most important biological processes that we engage in is reproduction. Through the reproductive process, we ensure the posterity of our race.
For us humans, reproduction is accomplished through sexual means. That is, in order to procreate, we engage in an activity which involves the use of hormones secreted by the endocrine and reproductive systems of our body.
Sex – related hormones are secreted by certain glands in our body to induce sexual desire and promote fertility. The lack of these hormones weakens our sex drive and impedes the reproductive process.
In this post we will explore the topic of male sex drive and fertility and how these can be enhanced through red and NIR light therapy.
The Makings of a Man
Let us begin with question. What makes a man, a man?
In this age of gender equality and open sexuality, we may have a lot of varying answers. But, answered from a purely biological perspective, what makes a man, a man is actually a sex hormone called testosterone.
Though women also produce this sex hormone, they do so only in small limited amounts. Men, however, secrete testosterone in greater or even exponential quantities.
What is testosterone?
Testosterone is the most prominent and the most abundant sex hormone in men. It singlehandedly controls and influences the development of male physical features.
During puberty, testosterone initiates the physical changes that turn a boy into a man – growth of the penis and testes; growth of facial, pubic and body hair; deepening of the voice; building muscles and strong bones; and getting taller.
Later in life, men also need optimal amounts of this hormone to produce sperm, increase sex drive, engage in sexual activity and be able to have children.

Closer look at your T
The body produces testosterone through the male gonad – the testes or the testicles.
The mechanism for the production of testosterone in our body involves a complex neurological process which starts from the brain down to the Leydig cells in our testicles.
When our brain through the hypothalamus detects that our body needs more testosterone, it secretes a hormone called gonadotropin-releasing hormone (GnRH). This GnRH travels to the pituitary gland at the back of our brain.
The moment our pituitary gland detects the GnRH, it starts to secrete two other hormones into the bloodstream – the follicle-stimulating hormone (FSH) and the luteinizing hormone (LH).
The FSH and the LH will then reach the testicles through the bloodstream. The bloodstream acts as a massive biological freeway where hormones, nutrients and wastes travel throughout our body.
Once in the testicles, the FSH kicks off sperm production in a process called spermatogenesis. On the other hand, the LH stimulates the Leydig cells to produce more testosterone.
Research suggests that Leydig cells can be found around seminiferous tubules forming groups of up to ten cells .
Because they are responsible for testosterone production, Leydig cells have features of steroid-secreting cells. They have large and well developed smooth endoplasmic reticulum, large and numerous lipid droplets, and significant numbers of mitochondria.
To know more about the histology of Leydig cells, check this study .
Leydig cells convert our body’s blood cholesterol to testosterone through a very complex biological process. To learn more about the mechanism of testosterone synthesis in the body, read this study .
Once synthesized, the testosterones produced by the Leydig cells in our testicles are sent back into our bloodstream. In the bloodstream, most of these hormones will immediately attach to sex hormone binding globulin (SHBG) and albumin – proteins that float around in the blood.
The rest of the testosterone that remains free and unbound to proteins in the bloodstream will circulate around the body. These free testosterones will enter the cells through active T – receptors which are mostly on our male genitalia. They give us virility and enhanced sex drive.
Testosterone production stops when our hypothalamus detects that we have enough of the hormone in our blood. It sends signals to the pituitary gland to stop secreting LH. Without LH, the Leydig cells in our testicles will then ramp down testosterone production.
Testosterone, Sex Drive and Male Fertility
Studies show that the production of testosterone in the body starts to increase significantly during puberty and begins to dip after age 30. Hence, our individual testosterone levels fall as we age .
As we are ageing, therefore, we need to have optimal testosterone levels in order to reap its many physical and psychological benefits – fighting depression, decreasing body fat, increasing muscle mass, strengthening the heart, strengthening the bones, decreasing chances of Alzheimer’s disease, improving cognitive ability, increasing competitiveness, increasing dominance, increasing tolerance for risk-taking and the subject of this blog post; improving sex drive and male fertility.
What does it mean to have optimal testosterone level in the body?
The word optimal means the most favorable. It comes from the root word optimum. Level, on the other hand, means the amount or number of something.
So, when we say we need optimal level of testosterone in our body, it means we need to have the amount of these sex hormones in our body that will give us maximum benefit.
Low levels of testosterone, also called Testosterone Deficiency Syndrome (TD) or Low Testosterone (Low – T), may have a variety of symptoms in men. These includes decreased sex drive, less energy, weight gain, feelings of depression, moodiness, low self-esteem, less body hair and possibly, balding as well as thinner bones.
Since testosterone is a sex hormone, it is not surprising at all that low libido or sex drive and erectile dysfunction are two of the first signs of low – T that we, men, notice. If you have noticed a decline in your mood or interest in sex, chances are, you might have low testosterone level in your bloodstream.
According to the American Urological Association (AUA) , about two men in every 100 may have low – T. Moreover, it is more common in men who have diabetes or are overweight.
How do we have optimal testosterone level?
To men who have symptoms of low – T, the most commonly suggested form of therapy is by testosterone therapy (TT). In TT, testosterone is delivered to the body in five ways – transdermal (through the skin), injection, oral (by mouth), intranasal (through the nose) and by pellets under the skin .
The Federal Drug Administration (FDA), however, cautions that while drugs that are supposed to increase testosterone might help some people, they may also slow down the body’s ability to naturally produce testosterone.
For instance, a study in 2013  concluded that in young men with classic hypogonadism caused by known diseases of the hypothalamus, pituitary or testes, TT induces a number of beneficial effects like the development of secondary sex characteristics, improvement and maintenance of sexual function, and increases in skeletal muscle mass and bone mineral density. However, it is not so among older men.
Moreover, the researchers of a study in 2016  noted in their conclusion that the benefits and safety of long-term use of testosterone replacement products are not known.
Hence, it is argued that the best way to improve testosterone levels is by adopting some lifestyle habits that can improve overall health and well-being. These lifestyle habits include getting enough sleep, maintaining a balance diet, losing weight, staying active, reducing stress, and avoiding drugs, cigarette and alcohol use.
Other ways that may also help increase testosterone levels are through supplementation either through taking vitamins and organic supplements or more recently, the rising trend of red and NIR light therapy (RLT).
Boosting Sex Drive and Male Fertility through Red and NIR Light Therapy
Recent studies explore how red and NIR light works to stimulate adenosine triphosphate (ATP) production, increase energy available to the cell, and in particular, increase the activity of the Leydig cells – the cells in our testicles which are responsible for testosterone production.
For example, a 2016 study  involved 38 men who had been diagnosed with hypoactive sexual desire disorder or sexual arousal disorder. These conditions are characterized by low libido or a lack of interest in sex.
Each of the subjects underwent an initial evaluation to determine the baseline level of interest in sex, with testosterone levels also being measured.
The researchers concluded that exposure to bright light increases testosterone levels and leads to greater sexual satisfaction in men with low sexual desire.
Another study in 2017 , this time on sperm motility, showed that sperm cells that are exposed to 630 nanometers of red light increased their swimming speed or motility and force. This means increased fertility which ensures reproductive success.
Still another study  on sperm motility was conducted in 2014. This time, fresh human semen specimens from patients diagnosed with asthenosphermia or low sperm motility were exposed to 830 nanometers of red light. Results showed that exposing human sperm cells with low – level light can improve their progressive motility.
Finally, a study in 2015  involving 30 men subjects was conducted. It focused on the effect of photobiomodulation (PMB) with light emitting diode (LED) on sperm motility in infertile men with impaired sperm motility – a condition called asthenozoospermia.
In the study, LED of different wavelengths were used in four groups namely: (1) 850 nanometers, (2) 625, 660 and 850 nanometers, (3) 470 nanometers and (4) 625, 660 and 470 nanometers. The results of the study confirmed that PMB using LED improved the sperm motility in asthenozoospermia regardless of the wavelength.
Since sperm motility is known as an effective parameter in male fertility, it follows that what these studies showed is that red and NIR light can boost male sex drive and at the same time, it can be a potential way to treat male infertility.
Red and NIR Light Therapy
Red and NIR Light Therapy (RLT) is also called photobiomodulation (PMB) or low-level light therapy (LLLT). It refers to treatments that use wavelengths of red and near-infrared light from light emitting diodes (LEDs) for health and wellness purposes .
Red and NIR light therapy works by delivering low-level radiation of red and near infrared light to the chromophores in the cells using cytochrome c oxidase (Cox) as the main light-absorbing protein .
Cytochrome c oxidase (Cox), or CCO, is a photosensitive enzyme found within the mitochondria of our cells. Studies show that the enzyme responds best to red and near infrared light .
After absorbing red and NIR light, the Cox in the mitochondria of the cell triggers an increase in the synthesis of adenosine triphosphate (ATP) – the body’s source of energy at the cellular level .

Are Red and NIR Light Therapy Devices Safe?
Though not many, there are compelling studies behind the effectivity and efficiency of red and near-infrared light therapy in relation to enhancing or boosting male sex drive and fertility.
Taking these studies into careful consideration, it is not totally surprising to see that more and more men are now turning to red light therapy devices for their sex drive and fertility problems.
An important question, however, still needs to be asked. Are red light devices currently in the market safe?
We at Leredd are confident that they are safe, efficient and cost-effective.
A study reported by the Harvard Gazette  website mentioned that researchers from the Massachusetts General Hospital (MGH) suggests that light therapy is safe and may even help patients with moderate brain injury.
It helps to also mention that Red and NIR light therapy uses LED devices that are approved by the FDA and other agencies like the CE and ROHS.
In addition, red and NIR light therapy devices do not make use of harmful electromagnetic radiation like ultraviolet rays, so it is safe. It uses, on the other hand, very low levels of radiant energy and does not hurt or burn the skin.
Most importantly, red and NIR light therapy is 100% non-invasive. Therefore, there is no need for a recovery time after treatment. Once you are done with the therapy, you can continue doing your daily activities without worry.
