Trying to conceive, especially through IVF, isn’t just a physical process. It’s an emotional, mental, and deeply cellular journey. For many women, it becomes a full-time commitment marked by hormone injections, rigid protocols, invasive procedures, and repeated cycles of hope and disappointment. And the numbers behind this experience are sobering.
Worldwide, more than 1 in 6 couples face infertility. In many cases, women bear the emotional and physical burden of treatment. IVF, egg retrieval, and hormone stimulation are not only taxing on the body but also financially and psychologically demanding. A single IVF cycle can cost thousands of euros or dollars, with success rates dropping significantly with age. For women over 35, the chances of live birth per cycle decrease, and for those over 40, IVF may fail up to 45% or more of the time. Even with the best medical care, many find themselves navigating a process that feels uncertain, exhausting, and often out of their control.
In this landscape, it’s understandable to seek gentle, supportive tools that can enhance your preparation—not as a replacement for medical treatment, but as a way to support your body at its most fundamental level. This is where red light therapy (RLT) enters the conversation. While it is not a medical device nor intended to treat or cure any disease, RLT is emerging in wellness research as a potentially valuable ally in the fertility journey. Its ability to stimulate cellular energy production, support hormonal balance, and create a more supportive environment for egg development and uterine health may offer a subtle but meaningful form of preparation before an IVF cycle.
Let’s take a closer look at how red light therapy may support your body, starting at the cellular level.
The Role of Mitochondria in Fertility
Mitochondria are often described as the "powerhouses" of our cells. However, in reproductive health, they're more than just energy centers. Healthy mitochondrial activity is crucial for:
1. Oocyte (Egg) Quality
Mitochondria are essential for egg maturation and development. Each oocyte contains hundreds of thousands of mitochondria, more than most other cells in the body, because developing an egg and preparing it for fertilization requires an enormous amount of energy. Mitochondria supply this energy in the form of ATP (adenosine triphosphate), which fuels key processes like chromosome alignment and spindle formation, which are crucial steps in ensuring the egg is genetically healthy and viable for fertilization.
When mitochondrial function is strong, the egg matures properly, its chromosomes align correctly, and it’s more likely to be fertilized and develop into a healthy embryo.
Poor mitochondrial function leads to low ATP levels. This can result in immature eggs, chromosomal errors, and a higher likelihood of failed fertilization or early embryo arrest. Mitochondrial decline is one reason why egg quality tends to drop with age.
2. Cellular Division in Embryos
After an egg is fertilized, it must divide multiple times to become a viable embryo. Each cell division demands high levels of energy, and mitochondria are the only source of that ATP. They also play a role in regulating oxidative stress and signaling pathways that control the pace and accuracy of embryonic development.
Efficient mitochondrial activity supports smooth, even cell divisions. The embryo grows in a balanced way, increasing the chance of successful implantation and a healthy pregnancy.
If ATP is lacking, the embryo may divide unevenly or stall in development. This can result in lower-quality embryos, increased risk of genetic abnormalities, or failed implantation.
3. Endometrial Receptivity
The endometrium is the inner lining of the uterus that thickens in preparation for a fertilized embryo. Mitochondria in the endometrial cells help produce the energy needed for cellular growth, repair, and blood vessel formation, all processes that are vital for creating a hospitable environment for implantation.
With good mitochondrial support, the endometrial lining becomes thick, oxygen-rich, and receptive. It produces the right molecular signals to encourage implantation and support early pregnancy.
Poor mitochondrial function can impair cell growth and limit blood supply, leading to a thin or poorly developed endometrial lining. This may lower the chance of implantation or increase the risk of early pregnancy loss.
Mitochondria, Aging, and How Red Light Therapy Powers Your Cells
As women age, one of the most significant changes in fertility stems from a gradual decline in mitochondrial function. Mitochondria are responsible for producing ATP, the molecule that fuels nearly every cellular process. Over time, factors such as stress, environmental toxins, and natural aging reduce the efficiency of these energy-producing structures. When mitochondrial output slows, it impacts egg quality, hormone production, and the ability of the uterus to prepare for implantation.
This decline isn’t limited to age alone. Conditions like PCOS or endometriosis are also linked to increased oxidative stress in reproductive tissues, which can interfere with mitochondrial activity regardless of age. When cells don’t generate enough ATP, the body has a harder time carrying out energy-intensive tasks like maturing an egg or thickening the uterine lining.
This is where red light therapy offers promising support. RLT uses specific wavelengths of red light, around 660 nanometers, and near-infrared light, typically around 850 nanometers. These wavelengths are able to reach deep into the skin and tissues where they are absorbed by an enzyme called cytochrome c oxidase, located inside the mitochondria. This enzyme plays a key role in the final steps of energy production. By stimulating this enzyme, red light therapy helps mitochondria work more efficiently and increases ATP output.
Higher ATP levels mean that cells can function at their best. In the ovaries, this can support healthier egg development. In the uterus, it may enhance endometrial cell growth and improve blood flow, both of which are crucial for creating a receptive environment for implantation. When mitochondrial health improves, so does cellular communication, tissue repair, and hormone response, all of which are essential for supporting fertility.
Unlike treatments that force hormonal changes or introduce synthetic compounds, red light therapy works by supporting the body’s own biology. It empowers your cells to perform their natural functions more efficiently, creating a stronger foundation for reproductive health.

How Red Light Therapy Supports Eggs, Embryos, and Implantation
Red light therapy (RLT), also known as photobiomodulation, is gaining attention for its potential to support fertility. By enhancing cellular energy production and improving tissue health, RLT may positively influence key aspects of reproduction. Let's explore how RLT can impact oocyte quality, embryo development, and endometrial receptivity.
1. Oocyte (Egg) Quality
Oocytes, or egg cells, require substantial energy to mature properly. Mitochondria, the cell's energy producers, play a crucial role in this process. As women age, mitochondrial efficiency can decline, leading to reduced ATP production and, consequently, diminished egg quality.
RLT delivers specific wavelengths of red and near-infrared light that penetrate tissues and stimulate mitochondrial activity. This stimulation enhances ATP production, providing oocytes with the energy needed for maturation. A study demonstrated that multiwavelength red and near-infrared photobiomodulation improved female fertility and reproductive health, suggesting potential benefits for oocyte quality .

2. Cellular Division in Embryos
After fertilization, embryos undergo rapid cell division, a process demanding high energy levels. Efficient mitochondrial function is essential to support this development.
Research indicates that red light exposure does not harm embryo development and may support cellular processes. A study found that red light exposure did not negatively affect the development and quality of mammalian embryos, suggesting its safety and potential supportive role during early embryonic stages.
3. Endometrial Receptivity
For successful implantation, the endometrium (uterine lining) must be receptive. This involves adequate thickness, blood flow, and cellular health.
RLT may enhance endometrial receptivity by improving blood circulation and stimulating cellular activity. Studies have shown that RLT can increase uterine blood flow and support the growth of endometrial cells, contributing to a more favorable environment for embryo implantation.

Incorporating red light therapy into fertility care routines may offer supportive benefits by enhancing cellular energy production and tissue health. As research continues, RLT presents a promising adjunct to traditional fertility treatments.
How to Integrate Red Light Therapy into Your Routine (Alongside IVF Treatments)
Adding red light therapy to your pre-IVF or IVF routine doesn’t need to be complicated. The key is consistency, especially in the weeks or months leading up to treatment. While every body is different, here’s a simple sample routine to help you get started:
Morning (5–15 minutes):
Begin your day with a quick red light therapy session using a device like the Kini (for targeted use) or Essential (for full-body support). Focus on areas like the lower abdomen and lower back, where the ovaries and uterus are located. This can help stimulate circulation, gently energize your cells, and support hormone-producing glands.
Midday (optional, 5–10 minutes):
If you experience fatigue or stress during the day, a quick midday session on your face or chest can support mood, energy, and nervous system regulation. It’s a great way to reset without relying on caffeine or stimulants.
Evening (10–15 minutes):
Use red light therapy again in the evening to wind down. This time, focus on full-body relaxation. The warmth and glow of the light can help signal your body to begin producing melatonin naturally, supporting better sleep and recovery. Pair this with calming rituals like breathwork, gentle stretching, or journaling.
How often should you do it?
Aim for 3–5 sessions per week, ideally daily if preparing for IVF. The consistency helps your body build up the benefits over time.
Start this routine at least 4–6 weeks before your IVF cycle for the best chance of cellular support. And remember: every purchase from Luminous Labs includes one-on-one guidance for a year, so you’re never left to figure it out alone.
As always, consult your doctor to ensure it fits safely alongside your fertility plan.
