If you’ve ever noticed a mismatch between how energetic you feel and your physical sensations, you’re not alone. Issues such as low libido, reduced sensitivity, dryness, or erectile dysfunction can be particularly frustrating because they often stem from stress, circulation, nerve health, hormones, sleep habits, medical conditions, and psychological factors.
At Deeply Vital Medical, we provide supportive, noninvasive options that fit into a broader wellness plan. One approach receiving significant attention is Red Light Therapy (RLT), also known as Photobiomodulation (PBM). We use physician-guided sessions to support whole-body wellness and sexual health by addressing the systems that help the body respond naturally.
While it is not a cure-all or a replacement for medical evaluation, it can be a useful tool when the goal is to support the systems that help the body respond.
Sexual function depends on healthy circulation. For women, blood flow supports arousal, lubrication, sensitivity, comfort, and the ability to orgasm. For men, erections rely on blood inflow and the ability to trap blood in penile tissue. When circulation is impaired, even slightly, it can manifest as “something feels off” before becoming a bigger health concern.
A key player in this conversation is nitric oxide, a molecule the body uses to help blood vessels relax and widen (vasodilation). When nitric oxide signaling is disrupted, achieving and maintaining blood flow can be more difficult, especially during arousal. Unlike temporary fixes that mask symptoms, Red Light Therapy aims to support the underlying cellular environment and tissue.
Photobiomodulation uses specifically optimized wavelengths of Red and Near-Infrared (NIR) Light to stimulate the mitochondria, the “power plants” of your cells. However, the benefits go far beyond a simple energy boost. This process is not meant to generate heat or cause tissue damage.
Mitochondria are not just energy-producing organelles; they regulate vital functions such as cell signaling, growth, aging, and programmed cell death (apoptosis). Their dysfunction directly affects overall cellular and organismal health and contributes to many diseases. They are like the cell’s motherboard, far more than just energy-makers, as they manage metabolism, calcium, and stress responses. When mitochondria fail, it can lead to various health issues. Dysfunctional mitochondria are linked to conditions like chronic fatigue, diabetes, heart disease, dementia, neurodegeneration, cancer, aging, and sexual dysfunction. Additionally, damaged mitochondria emit signals that may activate detrimental immune and inflammatory responses.
When you visit our NoMad, NYC office, your session triggers a multi-layered biological cascade:
1. The Circulation: Light photons are absorbed by mitochondrial enzyme cytochrome c oxidase, causing immediate release of nitric oxide, a potent vasodilator that relaxes blood vessels. This promotes optimal microcirculation, supporting the blood flow vital for arousal and sensitivity.
2. Calming the System: Cytokines & Endorphins: Chronic inflammation is a major factor in vascular and nerve dysfunction. PBM helps heal the body by reducing pro-inflammatory cytokines, such as TNF-α, and by promoting endorphin release. This dual effect alleviates physical discomfort and psychological stress, often barriers to intimacy.
3. Regeneration via Stem Cells & ATP: Unlike treatments offering only temporary benefits, PBM acts on a cellular level. It stimulates mesenchymal stem cell production and migration crucial for repairing blood vessels and nerves. By increasing ATP, which supplies cellular energy, PBM equips cells with the ‘fuel’ they need for repair, resulting in healthier, more responsive tissue over time.
Ready for a Science-Backed Reset in NYC?
At Deeply Vital Medical, we believe in addressing sexual wellness at the cellular level. By combining advanced biological pathways with a physician-guided approach at our 99 Madison Ave office, we help you move toward a more confident, vibrant version of yourself.
In a 2025 study in Lasers in Medical Science, researcher Gisele Moceline Junkoski and colleagues evaluated LED Photobiomodulation on human radial artery tissue (in vitro). They found that a combined Red + Near-Infrared Spectrum improved vascular function, including stronger vascular relaxation, increased nitric oxide bioavailability, reduced oxidative stress markers, and reduced ICAM-1 expression (an inflammation-related marker).
That matters because healthier blood vessel relaxation is a foundational step toward improved blood flow.
When people search for Red Light Therapy for sexual health, they usually want to know one thing: Does it actually help?
Human research is still developing, but there is meaningful preclinical and early clinical evidence pointing toward mechanisms that matter for sexual function, especially for people dealing with vascular or nerve-related changes.
For example, a 2023 study in Andrology by L. Yang and colleagues investigated Near-Infrared Laser treatment in rats with diabetes-induced erectile dysfunction. Their work focused on oxidative stress as a driver of tissue damage, and they reported improvements in erectile function outcomes in the treated animals.
This is not the same as a large human trial, but it supports a biologically plausible pathway: supporting tissue health in a condition where vascular and nerve factors often collide.
Deeply Vital Medical provides physician-guided whole-body Red Light Therapy to patients in NoMad, the Flatiron District, and Murray Hill. Conveniently located at 99 Madison Ave, just steps from Madison Square Park.
Deeply Vital Medical provides non-thermal, noninvasive sessions designed to support wellness goals in a safe, structured way. Our approach is based on Photobiomodulation principles, using clinically relevant Red and Near-Infrared wavelength ranges commonly discussed in the research literature. Depending on your goals, sessions may help with
If you are looking for sexual wellness light therapy, it is important to frame it as supportive care. We also encourage patients to address the basics that often affect sexual health: hydration, sleep quality, medications, metabolic health or comorbidities, relationship stress, mental health, and hormone levels, as appropriate.
Erectile function is not just blood flow. Nerve signaling plays a big role. That is why research models often evaluate both vascular and nerve outcomes.
In 2024, Limanjaya Anita and colleagues published a preclinical study in the World Journal of Men’s Health exploring Photobiomodulation parameters in a cavernous nerve injury model. They assessed erectile function along with tissue findings to identify supportive PBM settings.
Then, in 2025, Anita and colleagues published in Scientific Reports on Photobiomodulation therapy for diabetic erectile dysfunction, targeting neuroinflammation and neurovascular regeneration in a diabetic mouse model. Their protocol included Red (around 660 nm), Near-Infrared (around 830 nm), and combined treatment approaches.
For anyone searching for LED therapy for erectile function, these studies support two key ideas: erectile concerns can be neurovascular, and light-based approaches are being studied for their potential to support both sides of the equation, non-invasively.
The “Tiny Vessel” Connection: A Window Into Your Longevity
It is important to understand that the vascular system is a single, continuous network, and sexual health is a direct reflection of your overall cardiovascular health.
Why Size Matters
The blood vessels supplying the pelvic region are among the smallest in the body, often only 1–2 mm in diameter. In contrast, the coronary arteries (those surrounding your heart) are larger, typically 3–5 mm.
Because these pelvic vessels are so small, they act as a health barometer. They often show signs of reduced blood flow before the larger heart vessels are affected.
At Deeply Vital Medical, we view sexual wellness as a proactive way to support heart health. If you are experiencing changes in erectile function, it is the perfect time to:
Prioritize a Cardiac Evaluation: Identifying changes in these “tiny vessels” gives you a head start on protecting your heart. We strongly recommend seeing a cardiologist to ensure your entire vascular system is supported.
Support the Endothelium: The “lining” of your blood vessels (the endothelium) is what Red Light Therapy targets. By using PBM to release nitric oxide and reduce inflammation in the smallest vessels, you support the health of your entire circulatory system.
Integrated Care in NoMad, NYC: Dr. Lauren Weber focuses on this connection, ensuring that your Red Light Therapy plan at our 99 Madison Ave office is coordinated with your long-term cardiovascular wellness.
Sexual wellness also includes comfort. Dryness, irritation, and pain can quickly turn intimacy into something you dread, which can affect desire and confidence. RLT can help improve blood flow, lubrication, collagen, and tissue elasticity.
In 2025, P. C. Wu and colleagues published a pilot study in Frontiers in Medicine evaluating low-level laser therapy for genitourinary syndrome of menopause (GSM) and stress urinary incontinence (SUI). In the GSM group, the researchers reported improvements in sexual function metrics, including lubrication and pain domains on the Female Sexual Function Index (FSFI).
This is an early study, but it highlights that light-based therapies are being explored in women’s intimate health, not just men’s!
Most people want something practical. At Deeply Vital Medical, sessions are designed to be straightforward and comfortable, and we tailor recommendations to your goals and medical history. While protocols can vary, many patients do well with a short series of visits followed by periodic maintenance, depending on their response, overall health, and lifestyle factors.
You will get the most value when light therapy is paired with healthy lifestyle support, such as improving sleep, increasing physical activity, maintaining a healthy diet, reducing stress, avoiding alcohol and tobacco, and undergoing medical screening when symptoms suggest an underlying condition.
If you are curious about the benefits of Photobiomodulation and how they relate to circulation and sexual wellness, it may be worth a conversation. Deeply Vital Medical offers whole-body Red Light Therapy in New York, NY, with a patient-first approach that respects privacy, comfort, and real-life concerns.
