Reasons Red Light Therapy for Fertility Might Not Seem to Be Working
“I used RLT for my last cycle and it didn’t work”.
What's the deal? When everyone is hyped up for red light therapy - the stories of success are exciting and hope is high BUT you don't feel like it's working for you - or it seems to be creating issues instead of fixing them. What's going on?
We all know at some level that, that getting that positive test is influenced by a multitude of factors. photobiomodulation is one piece of a very complex puzzle, and while it can be beneficial, it’s essential to understand the many variables that come into play during a cycle (there's probably a lot more to consider that we don't even know about). Before we jump in I'm working with the assumption that you're also 'doing all the things' - nutrition, movement, stress management and tracking your cycles consistently.
Differing Diagnoses: Every Journey is Unique
Each of us have our own medical history and challenges. Each diagnosis brings its own set of variables that can impact our fertility.
The length of time you’ve been TTCing also matters. Women who have been TTCing for several years may face different hurdles compared to other women who have recently started their journey. The cumulative stress, emotional toll, and potential changes in ovarian function over time can all influence those outcomes.
Age: A Crucial Factor
Enough said.
Inflammation:
Inflammation is a critical factor that can impact fertility. Chronic inflammation in the body can affect ovarian function, egg quality, and even implantation. Women with autoimmune conditions or chronic inflammatory diseases may find that reducing inflammation is key to improving their chances. Red light therapy is a fantastic tool for reducing inflammation and enhancing cellular function, but it’s not a standalone solution. Combining red light therapy with other lifestyle modifications, such as an anti-inflammatory diet and stress management, can create a more supportive environment for conception. Ovarian reserve, as mentioned earlier, is another essential variable. Women with a lower ovarian reserve may have fewer eggs available during an IVF cycle, which reduces the chances of success. Red light therapy may help improve mitochondrial function in the ovaries, potentially enhancing egg quality, but again, it’s just one piece of the puzzle.
Endometrial Receptivity: Preparing the Soil
The endometrium, (lining of the uterus) plays a crucial role in supporting implantation and early pregnancy. Some women have issues with endometrial receptivity, making it difficult for an embryo to implant and thrive. Red light therapy has been explored as a method to improve blood flow and reduce inflammation in the endometrium, potentially enhancing receptivity. However, it’s important to remember that endometrial health is also influenced by various factors, including hormone levels, blood flow, and overall uterine health. A low-grade silent infection is another challenge - if it’s silent and you generally feel well you an have a lingering infection within the uterus for a looooooong time that is preventing implantation. Red light therapy will help modulate the immune system but unless you’ve had this investigation and treated the infection you’re going nowhere fast. If we’re working together my intake form will ask about number of sexual partners…so don’t be shocked when you see it.
Consider NeoFertility if Cycles Aren't Improving
If you've been using red light therapy consistently and your cycles still aren't showing the improvements you're hoping for, hormones remain suboptimal, cervical mucus production is poor, or you're still experiencing abnormal bleeding patterns it may be time to consider a more comprehensive root cause approach like NeoFertility.
NeoFertility uses a multifactorial treatment strategy that addresses underlying hormonal imbalances and follicle function through a structured three-phase approach: Assess (finding the problem), Balance (fixing the problem), and Allow (counting ‘good’ cycles). The program runs for about twelve effective cycles of treatment, but "good cycles" are only counted when specific criteria are met, satisfactory cervical mucus production, normal bleeding patterns, controlled PMS and period pain, and normal energy levels.
Treatment protocols may include medications to enhance follicle function and rupture, such as letrozole or clomiphene for follicle stimulation, DHEA supplementation (particularly for women with hypoandrogenemia or adrenal fatigue), naltrexone for clinical endorphin deficiency, and luteal phase support with cyclogest or HCG. For women with conditions like PMOS, insulin resistance, or luteinized unruptured follicle (LUF), additional interventions such as prednisolone, metformin, or GnRH therapy may be recommended.
NeoFertility emphasizes monthly blood testing to monitor progesterone and estradiol levels and ensure treatment is effective. The approach also addresses lifestyle factors through personalized diet modifications (often eliminating dairy, gluten, and sugar based on IgG food sensitivity testing), appropriate supplementation (Vitamin D3, Omega-3, B12, folate), and stress management. This comprehensive strategy recognizes that fertility challenges are rarely due to a single factor and requires addressing multiple variables simultaneously.
If red light therapy alone isn't delivering the cycle improvements you need, combining it with a structured treatment program like NeoFertility may provide the additional support required to optimize your hormonal environment and improve your chances of conception.
Photobiomodulation Variables: Dosage, Device, and Delivery
When using red light therapy as part of your pregnancy journey, it’s essential to consider the variables within the therapy itself. The research paper by Zein et al. highlights how critical these variables are for ensuring the effectiveness of PBM. The following factors should be carefully considered:
Dosage: The correct dosage is vital to achieving the desired effects. Too little light may not penetrate deeply enough to make a difference, while too much light could potentially cause harm or diminish the benefits. This concept is underpinned by the Arndt-Schultz law, which describes a biphasic dose-response where low doses stimulate, moderate doses inhibit, and high doses can damage cellular activity.
Device: Not all red light devices are created equal. The quality of the device, including the wavelength of light it emits, can impact its effectiveness. Red and near-infrared wavelengths are most often used in PBM for fertility, with red light (600-700 nm) being more effective for superficial tissues and near-infrared light (780-1064 nm) for deeper tissues. Look for devices that have been studied - and at the moment those studies are scarce.
Skin Contact and Delivery Method: Whether the light is applied directly to the skin or used at a distance can affect how much energy is absorbed by the tissues. Direct skin contact is generally preferred for deeper penetration. Additionally, the mode of delivery, whether continuous wave or pulsed can also impact effectiveness, with some studies suggesting pulsed light may be more effective for certain applications.
Joules Delivered: This refers to the total energy delivered during a session. It’s another critical factor that needs to be tailored to your individual needs to optimize the benefits of red light therapy.
Time of Day: The time of day when you use red light therapy may also influence its effectiveness. Recent research suggests that our cells respond differently to light exposure depending on the time of day, with potential variations in circadian rhythms affecting the outcomes. Discussing the optimal timing for your sessions with a light specialist may help maximize the benefits.
Skin Color: Skin color can influence how light is absorbed and penetrates the tissues. Melanin, the pigment responsible for skin color, can absorb light and may affect the depth at which red light reaches the target tissues. Individuals with darker skin may need adjustments in dosage or device settings to achieve similar therapeutic effects.
Propagation, Scattering, and Reflection: The way light propagates, scatters, and reflects within your body can also impact the effectiveness of photobiomodulation. Light can scatter as it travels through tissues, and some of it may reflect off the skin surface rather than penetrating deeply. These factors, though often not visible, are crucial in determining how much energy actually reaches the target tissues, influencing the therapy's effectiveness. This is why skin contact matters so much - not standing in front of a panel.
The Landscape Keeps Evolving
While red light therapy has shown great promise, it’s important to recognize that the science behind it is still evolving. We have made significant strides in understanding how light interacts with our cells and supports healing, but there is still much to learn. Researchers are constantly discovering new insights into how variables like light dosage, skin color, and time of day can affect outcomes. This ongoing research is helping to refine and improve red light techniques, but it also means that there may be limits to our current understanding.
It Takes Time…
And I know that’s not what you want to hear - when I was taking the Chinese herbs I wanted it to work NOW!
But we have to give the body time to respond to these changes. Persistence, resilience, and support are so important. While photobiomodulation can support your fertility journey, it’s not a silver bullet - it’s one more tool in your toolkit to improve your cellular health.
***There are also a small % of research participants who seem to be resistant to PBM*** Don't assume that's you (it's normal for our mind to focus on worst-case scenario when we're stressed). Give yourself a chance over several months, or longer to give your body the energy it has been starved of for so long.
I hope this helps explain a little more about why PBM may not seem to be working and why that might be.
