Red light therapy for fertility. By Dr Shabana Bora, MBBS, MRCOG, Consultant Gynaecologist and Fertility Specialist, ALMA Fertility

Red Light Therapy (RLT), or photobiomodulation, has been adopted as a noninvasive treatment that uses low-level wavelengths of red and near-infrared light to enhance cellular function, reduce inflammation, improve blood circulation, and optimise mitochondrial performance. These factors play crucial roles in reproductive health for both men and women.

It has gained widespread attention for its potential benefits on reproductive health for both men and women over the past decade, including improving ovarian function, sperm quality, hormonal irregularities, and fertility. 

How does red light therapy work?

Red Light Therapy works through photobiomodulation (PBM), where specific wavelengths of light (typically 600–1000 nm) penetrate tissues and interact with cellular components, particularly mitochondria. This interaction boosts adenosine triphosphate (ATP) production, enhancing cellular repair, reducing oxidative stress, and supporting tissue regeneration.

Initially developed by NASA to aid plant growth in space and accelerate wound healing in astronauts, this therapy mimics beneficial aspects of sunlight—excluding harmful UV—playing a key role in cellular function and overall health. Mitochondria is the body’s energy producer and power-essential biological process, but age, stress, and toxins can impair its efficiency, leading to reduced energy production and cellular decline.

Red Light Therapy directly stimulates mitochondria by penetrating the skin, restoring their function and energising cells. This reactivation supports a range of benefits, from wound healing and collagen production to improving skin conditions, helping with growth, reducing inflammation, and overall cellular rejuvenation. It makes it a versatile, noninvasive therapy for both aesthetic and general health applications.

How can Red Light Therapy be used beyond skin health?

Red Light Masks offer a range of benefits, primarily marketed for skin health and anti-ageing. These masks work by stimulating collagen and elastin production, which is believed to help reduce wrinkles and fine lines and improve skin elasticity, resulting in a brighter, more youthful complexion.

Beyond skincare, red light therapy may support ‘wellness’ by enhancing cellular energy production and reducing oxidative stress, which contributes to general ageing and cellular damage. Some research suggests that Red Light Therapy can positively impact fertility, thyroid function and hormonal balance, potentially aiding in stress reduction and regulating cortisol levels.

Red Light Therapy and Female Fertility

As research in this field continues to evolve, Red Light Therapy, which is already widely used in the USA, is thought to be a valuable adjunct to fertility treatment and may also optimise natural conception and overall reproductive health. 

For clients exploring non-invasive and supportive therapies for fertility and reproductive health, Red Light Therapy offers a low-risk option with potential long-term benefits.

Red Light Therapy for egg health and ovarian function

The ovaries require optimal mitochondrial activity to support oocyte (egg) development. Studies have shown that red and near-infrared light can enhance mitochondrial efficiency, increasing energy production in ovarian cells. Whether this improves egg quality is not known, as there is no good evidence that it does. However, there are a number of case reports that may demonstrate that Red Light Therapy has improved rates of live births in assisted reproduction (IVF) [1]. 

It’s worth noting that evidence is based on a very low number of cases and in reported case report studies and has not been investigated in randomised controlled trials. However, as RLT is a complementary and non-invasive therapy, that not only provides cellular benefit but also promotes relaxation it may be of added benefit while going through fertility treatment.  

2. Using Red Light Therapy for fertility, hormonal balance and menstrual cycle regulation

There are several gynaecological concerns, such as PCOS, endometriosis, or associated thyroid dysfunction, which are known to impact fertility and general reproductive health. 

RLT may assist in modulation of hormone-producing cells, potentially improving endocrine function, particularly beneficial for those suffering from PCOS. 

This may ultimately result in women achieving more regular menstrual cycles, resumption of ovulation and subsequent improved luteal phase support; all of which are critical factors for successful conception to occur.

3. Managing Endometriosis and Pelvic Pain with Red Light Therapy 

Endometriosis, a condition in which endometrial tissue grows outside the uterus, can cause significant pelvic pain and fertility issues. Some studies suggest that Red Light Therapy’s anti-inflammatory effects may reduce pain, promote tissue repair and reduce abnormal cell proliferation associated with endometriosis. 

In addition, improved microcirculation can enhance oxygen delivery to affected tissues, improving patients’ symptoms of the condition. A small randomised controlled trial in South Korea found some improvement in quality of life and pain symptoms [3]. 

4. Using Red Light Therapy for IVF

For successful implantation to occur during an IVF cycle, the endometrial (womb) lining must be adequately thick and receptive to the embryo. Red Light Therapy has been linked to enhanced blood flow and angiogenesis (the formation of new blood vessels), which is believed to improve endometrial receptivity. 

How does Red Light Therapy help male fertility?

1. How Red Light Therapy helps sperm health

Male fertility is largely assessed by sperm count, motility (the way the sperm move), and morphology (the shape of the sperm). Some human studies [4] and animal studies [5] have shown that Red Light Therapy, when applied at appropriate dosages, can enhance sperm mitochondrial activity, leading to improved motility and vitality.

This may be particularly relevant for men experiencing suboptimal sperm parameters due to oxidative stress, inflammation, infection or lifestyle factors; however, changes in lifestyle factors such as smoking, vaping, drinking, and recreational drugs will have a profound negative impact on sperm health. 

2. Testosterone Production

Leydig cells in the testes produce testosterone, a hormone crucial for sperm development, libido, and overall male reproductive function. Red Light Therapy is thought to stimulate these cells with exposure, enhancing testosterone levels. 

Things to consider when having Red Light Therapy for IVF or fertility 

While Red Light Therapy is generally regarded as safe, the effectiveness depends on factors such as wavelength, intensity, and duration of exposure. Overuse or excessive heat exposure may have counterproductive effects, particularly on sensitive tissues. 

Consulting a healthcare provider or fertility specialist before incorporating Red Light Therapy into a reproductive health regimen is advisable, especially for individuals undergoing medical treatments or dealing with underlying conditions.
