How Solis Red Light Therapy Reboots Men’s Hormonal Health
Unlike supplements that rely on absorption through the gut, Solis red light therapy directly targets the Leydig cells in the testes - the very cells responsible for testosterone production. Near-infrared wavelengths (e.g. 850nm) penetrate deep enough to reach these structures, delivering focused stimulation where it matters most.
Testosterone production is energy-intensive - and mitochondria are the power source. Red light is absorbed by these mitochondria, triggering a surge in ATP (adenosine triphosphate). This fuels vital processes like hormone synthesis, sperm development, and cellular repair, helping your body function at its peak.
By energising your hormonal and reproductive systems, red light therapy encourages the body to rebalance itself naturally - without synthetic hormones or side effects. This helps restore healthy libido, optimise fertility, and improve sexual function by improving blood flow, hormone signalling, and testicular health.
Like strength training, red light therapy works best with consistency. With regular use, hormone production and sperm quality can improve measurably within weeks, while long-term users often report sustained energy, confidence, and vitality as cellular performance continues to improve.

What else does the science say?
Emerging research into red and near-infrared light therapy reveals compelling benefits for men’s health. Clinical studies have shown improvements in testosterone production, sperm quality, libido, and erectile function. The specific wavelengths used in Solis panels enhance cellular energy production in tissues critical to male vitality - such as the testes, adrenal glands, and vascular system. As evidence grows, more health professionals are recognising red light therapy as a powerful, drug-free tool to support hormonal health, reproductive function, and overall male wellbeing.
In a preliminary in vitro study by Salama & El-Sawy, semen samples from 27 men (with and without asthenospermia) were exposed to a red LED light (~636 nm). Researchers found significantly increased progressive sperm motility after 2–10 minutes of red-light exposure compared to controls. The motility boost was seen in both washed and unwashed semen, with washed samples showing the greatest improvement. The authors conclude that red LED phototherapy is a promising, safe tool to enhance sperm motility in vitro, potentially improving outcomes in intrauterine insemination (IUI).

In a 2017 laboratory study (Scientific Reports) by Preece et al., human spermatozoa were exposed to 633 nm red laser light (5.66 mW/cm²). Using computer-assisted tracking, the team observed sperm swam 17–47% faster than untreated sperm, with speed increases evident within 35 minutes of irradiation. Importantly, no significant oxidative DNA damage was detected in the irradiated sperm, indicating the treatment did not harm genetic material. This suggests that red-light photobiomodulation can safely boost sperm motility (a key factor for fertility) without compromising DNA integrity. Notably, 633 nm falls in the Solis red-light range (~630 nm).

A 2021 in vivo experiment by Rezaei et al. investigated photobiomodulation in a male infertility model. Thirty-two mice with busulfan-induced testicular damage (azoospermia) received low-level light therapy to the testes at either 0.03 J/cm² or 0.2 J/cm² energy density. The low-dose red/NIR PBM (0.03 J/cm²) produced striking results: it significantly increased serum testosterone levels, boosted the number of spermatogenic cells (indicating higher sperm count), and reduced markers of oxidative stress compared to untreated controls. Treated mice showed improved sperm parameters and fewer apoptotic (dying) cells in the testes. These outcomes suggest that photobiomodulation (using wavelengths in the Solis range) can support hormone production and spermatogenesis, pointing to a potential therapy for low sperm count or quality.

In a double-blind clinical trial (Lasers Surg. Med., 2019) by Cassano et al. (at Harvard/Mass. General Hospital), 20 men with major depression (and associated sexual dysfunction) were given transcranial photobiomodulation or sham treatment. The active group received near-infrared light (~820–830 nm) to the forehead (frontal cortex) twice weekly for 8 weeks. Outcome measures of libido and sexual performance (desire, arousal, orgasm satisfaction) showed significant improvement in the NIR-treated group versus sham. Specifically, sexual function scores improved by an average of ~2.5 points in the NIR group, compared to ~0.5 in controls. This indicates that 830 nm-range NIR therapy enhanced sexual desire and satisfaction, beyond what could be explained by mood improvement alone. The wavelength (~823 nm) lies in the Solis near-infrared range, highlighting a possible non-pharmacologic option for low libido.

Testimonials
James R.
My testosterone bloodwork came back up 30% after 8 week
I started using the panel five days a week, aiming at the lower abdomen as recommended. After two months, I genuinely felt more energised and clearer mentally. Blood tests confirmed my testosterone had increased significantly - and this was without any medication. I’m sold.
Dan P.
Ask my wife?
Was sceptical at first, but after three weeks of consistent use, I noticed a change - stronger libido, better mood, and a general sense of drive that I hadn’t felt in years. My partner even asked what I was doing differently.
Ross N.
Trying to conceive - this helped get my sperm count back in the green
After a routine check-up flagged sluggish motility, I started looking into natural ways to support fertility. Came across red light therapy and gave it a go. Three months in, new tests showed big improvements. We’re now expecting our first baby.
Male Health FAQs
How long does it take to see results for testosterone or libido?
Most men begin noticing subtle changes - like improved energy or drive - within 2–4 weeks of consistent use. Clinical studies suggest testosterone levels may increase measurably in as little as 2 months. As with fitness or nutrition, consistency is key to long-term hormonal balance and performance.
Where should I use the red light for testosterone benefits?
To support testosterone production, panels should be directed toward the lower abdomen or groin area - ideally at a distance of 6–12 inches, for around 10–15 minutes per session. This safely stimulates the Leydig cells responsible for natural testosterone production, helping your body work as it should.
Is red light therapy safe for male reproductive health?
Yes — when used correctly, red light therapy is non-invasive, drug-free, and well-tolerated. The wavelengths used in Solis panels are clinically tested and do not overheat or damage tissue. In fact, studies show improved sperm motility and reproductive function over time, making it a safe and powerful tool for men.
How often should I use Solis for hormonal support?
For best results, we recommend 4–6 sessions per week. Just 10–15 minutes a day is enough to stimulate testosterone production and promote hormonal balance. Like training or supplementation, regular use delivers stronger and more sustained improvements over time.
Do I need to be undressed for it to work?
Yes - red and near-infrared light need direct skin exposure to be effective. Clothing blocks the wavelengths from reaching the target tissue, especially when treating areas like the lower abdomen or groin. For hormonal and fertility benefits, skin contact ensures the light reaches the cells responsible for testosterone and sperm production.
Is there an age where red light therapy stops being effective for testosterone?
While testosterone naturally declines with age, red light therapy can benefit men in their 20s through to their 60s and beyond. Whether you're optimising for performance or restoring balance, the treatment works by supporting your body’s natural systems — no matter your stage of life.
Male Hormonal Health Usage Guide
Optimal Positioning
Place your Solis panel 6–12 inches from your body. For testosterone and fertility support, position the panel to target the lower abdomen or groin area — where the testes and Leydig cells are located. Keep the panel perpendicular to ensure even light coverage and maximum absorption. For systemic hormonal benefits, you can also target the lower back (adrenal glands) or sternum (general energy and circulation support).
Dosage Protocol
Start with 10–15 minute sessions, 5–6 days per week. Use both Red (630nm/660nm) and Near-Infrared (810–850nm) modes for full-spectrum benefit. Stick with consistent sessions for at least 4–8 weeks to support testosterone production, libido, and fertility.
Habit Stacking
Red light therapy fits seamlessly into your daily routine — no downtime, no fuss. Maximise the benefits by pairing it with other healthy habits:
Morning Momentum Stack - Kickstart your day with a Solis session while doing a breath work routine or journaling for the day ahead. This helps regulate cortisol, boost energy, and support natural testosterone production - all before your first coffee. Ideal for setting a focused, grounded tone for the day ahead.
Evening Recharge Ritual - Use Solis while winding down — pair it with a magnesium drink, low blue light, or 10 minutes of stretching. This signals your nervous system to relax and supports deeper hormonal recovery overnight.
Fertility Support Stack - For men trying to conceive, combine your RLT session with daily supplements (e.g. zinc, CoQ10) and a clean diet — amplifying mitochondrial health and sperm quality.
