Can Red Light Therapy Help Improve Fertility?

Infertility is a growing concern, about 10-15% of couples face challenges with infertility. While assisted reproductive technologies like IVF have helped many couples, they can be prohibitively expensive and are still not a guarantee. This has led many people to explore natural and alternative therapies that may support fertility. One emerging therapy that has shown promise in improving fertility is red light therapy. But does it really work? Let’s take a closer look at what red light therapy is, how it may impact fertility, the evidence behind it, and how it compares to other fertility treatments.

Can Red Light Therapy Help Improve Fertility?

Why Fertility Issues are Common?

Before diving into the possible red light therapy solution, it’s important to understand why fertility challenges arise in the first place. There are many contributing factors to reduced fertility that stem from our modern lifestyles and environmental exposures.

For women, common barriers include:

  • Age – female fertility declines after 35 and drops rapidly after 40. Older eggs may have chromosome abnormalities.
  • Hormone imbalances – conditions like PCOS affect ovulation. Thyroid disorders also impact hormones.
  • Poor egg health – caused by oxidative stress, toxins, genetics, and dietary deficiencies.
  • Structural problems – issues like blocked fallopian tubes, fibroids, endometriosis.
  • Unhealthy lifestyle habits – being over- or underweight, smoking, excessive alcohol intake.

For men, reduced sperm quality is often the culprit:

  • DNA damage – from free radicals, toxins, high fever, drugs, radiation exposure.
  • Motility issues – sperm don’t swim properly due to structural defects.
  • Morphology problems – abnormally shaped sperm have difficulty reaching the egg.
  • Low sperm count – caused by varicocele, undescended testes, hormone imbalance.
  • Antisperm antibodies – when the immune system attacks sperm cells.

As you can see, the reproductive systems are complex and delicate. There are so many steps required to generate a healthy egg and sperm, come together to fertilize, form an embryo, and successfully implant. Disruptions anywhere along the chain can derail the baby-making process. This is why fertility treatments aim to optimize every aspect of reproductive function.

What is Red Light Therapy?

Before diving into the fertility benefits, let’s first cover the basics of what red light therapy is. Red light therapy involves exposing your body to red and near-infrared light to provide therapeutic benefits. These wavelengths of light are considered “photo-biomodulation” because they positively alter your body’s cellular functions.

Red light therapy can be done using at-home LED devices, such as light panels you sit near for a certain length of time. Or you can undergo red light therapy in a clinic setting. Most fertility clinics that offer red light therapy have large, full-body LED beds you lay inside for treatment.

No matter how it’s administered, red light therapy delivers natural, drug-free benefits to improve cellular function. The red and near-infrared light gets absorbed into your cells, which activates healing and regenerative processes. It’s a painless, non-invasive way to improve overall health and target specific conditions.

How Does Red Light Therapy Work to Improve Fertility?

Years of research support red light therapy for healing wounds, reducing inflammation and pain, protecting against oxidative damage, and stimulating tissue regeneration. It’s a proven treatment for conditions like hair loss, skin disorders, joint problems, neurological injury, cardiovascular disease, and damage from cancer treatments like oral mucositis.

But what does this have to do with fertility? It turns out, quite a lot. Red light seems to flip switches in both female and male reproductive systems for improved functioning. Here are some of the key ways red light therapy may improve reproductive function and fertility:

1. Improves Egg Quality

Egg quality declines naturally with age, negatively impacting fertility. Suboptimal egg health is a common cause of conception issues and miscarriage.

By influencing hormones, growth factors, and cellular function, red light may improve egg quality. This enhances the viability of the egg for fertilization and early embryo development.

2. Reduces Inflammation

Excess inflammation can interfere with conception and pregnancy. The cytokines released during inflammatory responses are thought to impact fertility and embryo implantation.

Red light therapy has natural anti-inflammatory effects. The light stimulates cells to produce more antioxidants and anti-inflammatory cytokines.

Lowering excess inflammation creates a more favorable cellular environment in the reproductive system. This allows ovulation, fertilization, implantation, and early embryo development to proceed

3. Increasing Sexual Function and Health

In both men and women, red light has been shown to increase blood flow and circulation to the genitals. This can improve sexual arousal, function, and overall sexual health. Improving this aspect alone can help some couples struggling to conceive naturally.

4. Balances Key Hormones

Hormonal imbalances can affect fertility in both sexes. In women, issues like PCOS often stem from irregular estrogen and progesterone levels. While low testosterone reduces sperm count in men. Red light therapy helps balance reproductive hormones in the following ways:

  • Increases testosterone levels in men
  • Regulates estrogen and progesterone levels in women
  • Reduces high prolactin levels
  • Improves thyroid hormone imbalance
  • Lowers high cortisol levels caused by stress

By optimizing hormonal balance, red light removes a major obstacle to fertility for both sexes. It provides an alternative to hormone medications that can cause unwanted side effects.

5. Increases ATP production in eggs and sperm

Red light boosts ATP synthesis in mitochondria. Higher ATP levels in sperm and egg cells provide the energy needed for improved motility and vitality. This optimizes the chances that sperm can reach and penetrate the egg.

6. Protects reproductive cells and tissues

The rejuvenating effects of red light therapy help protect delicate reproductive cells and tissues from damage. This preserves fertility and reproductive capacity as both men and women age.

In summary, red light therapy provides holistic benefits by supporting healthy reproductive processes on a foundational cellular level. Even if a specific fertility issue is present, improving foundational cellular activity can create an optimal environment for conception.

Red Light Therapy Research for Fertility

While still an emerging area, a number of studies have already demonstrated the potential for red light therapy to improve fertility:

  • In a 2004 study, red light therapy significantly improved oocyte (egg) quality in women undergoing in vitro fertilization (IVF) treatment.
  • A 2018 study found that red light therapy significantly improved sperm survival, motility and speed.
  • Sperm DNA damage is associated with reduced fertility, increased miscarriage rates, and developmental problems in offspring. A 2017 study showed that red light therapy can reduce sperm DNA damage, a known factor in male infertility, by up to 50%.
  • Multiple studies have found that red light therapy can increase testosterone levels. Testosterone plays a vital role in sexual function and many other health-related phenomena.
  • In a 2019 trial on mature female mice, it was found that red light therapy could also help improve ovarian function and promote ovulation.

While not extensively studied yet for fertility, the existing research indicates red light therapy holds significant promise for enhancing reproductive function in both women and men.

Red Light Therapy vs. Other Fertility Treatments

For couples struggling to conceive naturally, treatment usually starts with drug therapies to induce ovulation and intrauterine insemination (IUI) before progressing to advanced techniques like IVF. Compared to these conventional fertility treatments, red light therapy is emerging as an attractive option because it is:

Non-Invasive: Red light therapy simply requires brief exposure to red and infrared light emitted from an LED device. It does not require injections, surgery, or implanting embryos. This makes it low risk with virtually no side effects.

Drug-Free: Red light provides a natural way to improve fertility without taking ovulatory medications like Clomid or gonadotropins that can cause side effects. Avoiding drugs is appealing to many couples.

Less Expensive: A cycle of IVF costs over $12,000 on average in the US. In comparison, red light devices cost a few hundred dollars for at-home use. Red light therapy is more affordable and accessible.

Efficient: Traditional IUI and IVF cycles require frequent ultrasounds, lab testing, and office visits. Red light therapy allows couples to improve their fertility at home on their own schedule.

Holistic: Red light aims to optimize the entire reproductive environment. Rather than forcing ovulation, retrieving eggs or creating embryos in a lab, it helps normalize the body’s natural fertility processes.

However, red light therapy may not be advisable for couples with severely compromised fertility or tubal occlusion. These cases will likely still require IUI, IVF or surgery. But for unexplained infertility or moderate male or female factor infertility, red light therapy is a promising option before proceeding to advanced ART.

Choosing a Red Light Therapy Device

If you decide to pursue red light therapy for fertility, be sure to choose an effective device:

  • Select a full body panel that allows both partners to be treated simultaneously. RedDot LED device features full-body panel with medical-grade LEDs.
  • The RedDot LED ensure the device emits light in the optimal wavelength range of 630-660nm for red light and 810-850nm for near-infrared. Low quality LEDs may not emit therapeutic wavelengths.
  • Choose LEDs over lasers for safety and efficiency. RedDot LED provide more complete and uniform coverage.
  • Look for a power density output of at least 30-50 mW/cm2 to penetrate tissue effectively. Higher power density gives better results.
  • Get a device with near-infrared capability for enhanced benefits. Near infrared enhances the red light effect. The RedDot LED device has two wavelengths: red light and near-red light, and has more comprehensive functions.
  • Pick a product from a reputable manufacturer that provides a warranty and good customer service, such as RedDot LED. Beware of cheap imitation devices.

Following these tips will ensure you choose a high quality product that delivers the fertility and health enhancements red light therapy promises.

Are There Any Side Effects of Red Light Therapy?

One of the benefits of red light therapy is the remarkably low risk of adverse side effects. The moderate light energy is gentle on the body and well-tolerated.

That being said, here are some considerations:

  • Mild headache and fatigue – Can occur at first as the body adjusts. Dose lightly and hydration can help.
  • Skin sensitivity – Reduce exposure time if irritation develops. Consult doctor if it persists.
  • Hormonal fluctuations – Some women report spotting between periods as hormones recalibrate.
  • Interactions – Inform your doctor of all supplements and medications you take.
  • Eye damage – Avoid looking directly into the light. Use protective eyewear.

Overall red light therapy is very low risk, especially when adhering to responsible treatment protocols. The potential benefits for fertility likely outweigh the low chance of mild side effects in most trying-to-conceive women and men.

Guide to Using Red Light Therapy to Boost Your Fertility

If you and your partner have been trying to conceive without success, incorporating red light therapy into your fertility plan may be worth considering. Here is a practical guide to using red light treatment to maximize your chances of pregnancy:

Choose the right device: Look for an LED device that emits wavelengths between 600-800nm to target the colors absorbed by cytochrome c oxidase. Select a light with enough power density for the coverage area you need. Hands-free pads or panels designed for fertility may offer the best ergonomics.

Use it consistently: Be diligent about using your device 3-5 times per week to allow the light therapy to have a consistent, cumulative effect. Consistency is key to seeing benefits.

Target the reproductive organs: For men, aim for the scrotum/testes area. For women, use an intravaginal wand or external pad pointing at the ovaries/uterus. Position the device close enough for maximum light penetration.

Do a treatment cycle: Use the red light daily for 3-6 months to improve egg and sperm quality before actively trying to conceive. This allows time for optimal fertility enhancement.

Time treatments strategically: For women, use red light therapy from days 1-14 of your menstrual cycle to target the development of each new egg. For men, every other day is sufficient.

Support yourself: Eat a nutrient-rich diet, manage stress, limit alcohol, and take supplements like antioxidants. Adopting a healthy lifestyle optimizes the effects of red light therapy.

Be patient: Give the light treatments time to work and boost your natural fertility. It can take 3-6 months to see benefits. Have patience and stick with it.


In summary, red light therapy is a proven, natural way to enhance fertility without the risks and side effects of medications or surgery. Clinical studies back its safety and effectiveness. At-home use makes red light therapy for fertility easy and affordable to try on your own. Wishing you the best of luck on your conception journey ahead!
