Sexual health is a barometer of how healthy you are in general. When you are sexually healthy, that radiates out to positively affect all other forms of health: physical, mental, emotional, social, spiritual, and environmental.
Summary
- Sexual health serves as a vital barometer for overall longevity, requiring harmony between physical, mental, and social health to reduce stress and lower the risk of all-cause mortality. - Managing stress is essential for sexual function, as shifting the brain into a parasympathetic state via mindfulness or neuro-technology is necessary to maintain desire and arousal. - Boosting blood flow by optimizing nitric oxide is critical; this involves habits like nose breathing while avoiding antiseptic mouthwash and medications that disrupt chemical pathways. - Hormone optimization for both men and women is a critical anti-aging tool that helps prevent cardiometabolic diseases, dementia, and muscle wasting associated with age-related decline. - Regenerative medicine, including stem cell therapy and shockwave treatments, can be used alongside pelvic floor exercises and red light therapy to repair and revitalize sexual organ structures.

Sexponential Medicine Cast Sexual Health As A Mirror Of How We Age
At Biohacker Summit 2022 Amsterdam, Dr. Amy Killen Argued That Desire, Blood Flow, Hormones, And Regenerative Therapies Belonged At The Heart Of The Longevity Conversation
There was a moment early in Dr. Amy Killen’s talk at **Biohacker Summit 2022 Amsterdam**, held in **Amsterdam, Netherlands** on **15 October 2022**, when she reduced a room full of optimization enthusiasts to a simple true-or-false quiz.
Was sexual health only important if you had a partner? False. Was it only relevant when you were young? False. Was it the same thing as reproductive health? False. Did it have nothing to do with longevity? Also false.
From that opening, Killen’s presentation, **“Sexponential Medicine: Enhancing Sexual Health For Longevity & Optimization,”** made its case with unusual clarity: sexual health was not a luxury, nor a niche concern, nor a matter to be quarantined from the broader science of aging. It was, she insisted, one of the clearest windows into how the body was performing as a whole.
“**Sexual health is important whether you have a partner or not, because it’s not about them, it’s about you,**” Killen said. “**It doesn’t matter how old you are; it is a vital indicator of how well you are aging.**”
Sexual Health As A Longevity Barometer
Killen’s central claim was both intimate and systemic. Sexual function, she argued, depended on the harmonious cooperation of nearly every major axis of human health: neurological signaling, vascular integrity, endocrine balance, emotional regulation, stress load, and tissue resilience.
“**When your neurotransmitters are firing in harmony, your hormones are dancing, and your blood is flowing without obstruction to every nook and cranny of your body, you know that you are aging well,**” she told the audience.
That framing recast sexual health from a private concern into a clinical marker. In Killen’s telling, it was less a side effect of wellness than a barometer of it. A sexually healthy person, she suggested, was often displaying the downstream effects of better sleep, lower stress, healthier blood vessels, stronger hormonal signaling, and more robust mental wellbeing.
She pointed to evidence linking sexual activity with lower stress, improved self-image, better immune function, and improved sleep. More strikingly, she referenced data suggesting that in older adults, greater sexual activity correlated with reduced cognitive decline, and in men, sex once or twice a week was associated with a 50 per cent reduction in all-cause mortality over ten years.
In a conference world often crowded with supplements, gadgets, and biomarkers, Killen’s thesis was refreshingly blunt: if sexual health was faltering, something larger might be too.
Stress, Busyness, And The Assault On Desire
If there was a villain in Killen’s framework, it was not age alone. It was modern life.
“**Stress and busyness are among the biggest killers of sex drive,**” she said. “**To flourish, we must prioritize practices that put us in a rest and relax state, where desire, arousal, and connection can truly thrive.**”
This was the first pillar of her four-part model, which she called **Sexponential Medicine**: mind your mind, boost blood flow, optimize hormones, and support the structures.
The brain, she reminded the audience, was the body’s largest sex organ. Desire, arousal, and orgasm began there, and under chronic stress, the body’s chemistry shifted away from receptivity and toward vigilance. In practical terms, that meant parasympathetic activation mattered. Breathwork, mindfulness, journaling, time in nature, and newer neurotechnology tools all had a role in helping the body move from fight-or-flight into rest-and-relax.
Killen noted that a new generation of devices originally designed for depression, insomnia, PTSD, and anxiety had shown an unexpected side effect: improved sexual desire and arousal. The implication was not merely commercial. It was conceptual. Sexual wellbeing could improve when the nervous system was calmed.
Blood Flow, Nitric Oxide, And The Hidden Cost Of Everyday Habits
The second pillar was vascular health. Sexual organs, like every organ, required blood flow. As arteries narrowed with age and endothelial function declined, arousal became harder to achieve and sustain.
That led Killen to nitric oxide, the vasodilator that allows blood vessels to open and deliver blood efficiently throughout the body. By age 40, she said, production had already fallen by roughly half.
Her recommendations ranged from the familiar to the oddly overlooked: exercise, sunlight, red light therapy, sauna, hyperbaric oxygen, and pulsed electromagnetic field therapy. But her most immediate advice came in two deceptively ordinary forms.
First: breathe through the nose.
Killen described nasal breathing as a simple way to support nitric oxide production, even recounting reports from patients who resumed waking erections after using mouth tape at night to prevent mouth breathing.
Second: be careful with antiseptic mouthwash and acid-blocking medications.
Dietary nitrates from leafy greens, beets, and arugula can be converted into nitric oxide, she explained, but only if oral bacteria remain intact and stomach acid is sufficient. Frequent use of antibacterial mouthwash can disrupt the first step of the process. Proton pump inhibitors can disrupt the second.
The point was larger than sex. Nitric oxide, Killen argued, was fundamental to blood flow in the brain, muscles, heart, and genitals alike. Small habits could quietly blunt one of the body’s most essential signaling systems.
Hormones, Menopause, And The Quiet Crisis In Testosterone
Killen’s third pillar, hormone optimization, moved into more politically and medically charged terrain.
For women, she framed ovarian health as a neglected cornerstone of longevity science. Menopause, she argued, was not merely a life stage to be endured but a profound endocrine event with systemic consequences.
“**Your ovaries are one of your best anti-aging tools,**” she said. “**Menopause increases the risk of developing almost all other diseases, and investing in ovarian health is a crucial part of the conversation about women’s longevity.**”
She linked declining estrogen, DHEA, and testosterone to increased risks of cardiometabolic disease, osteoporosis, sarcopenia, dementia, and depression. She also lamented the mismatch between the billions flowing into longevity research and the relative scarcity of investment in ovarian aging.
For men, she described low testosterone as an epidemic. Citing data that testosterone levels had dropped roughly 1 per cent annually since the mid-1980s, she warned that the decline was not simply a matter of individual aging but of population-level deterioration. Sedentary living, poor sleep, obesity, chronic stress, and widespread exposure to endocrine-disrupting chemicals all formed part of the explanation.
The urgency in her message was not confined to libido. Low testosterone, she said, was associated with obesity, diabetes, heart disease, and increased mortality.
Regenerative Medicine And The Rebuilding Of Sexual Tissue
The fourth pillar of Sexponential Medicine dealt with structure itself: pelvic tissues, sexual organs, and the physical architecture that supports function.
Here Killen entered the territory of regenerative medicine, describing treatments in her practice that used autologous stem cells from bone marrow, fat, or blood. These cells, once processed and injected into penile or vaginal tissues, were intended not to become new tissue directly but to signal existing cells to repair, regenerate, and restore function.
In men, she said, the goal was improved erection quality, sensation, and tissue health. In women, it was increased arousal, enhanced sensation, and relief from issues such as stress urinary incontinence.
She also highlighted **low-intensity extracorporeal shockwave therapy**, a non-invasive treatment intended to promote blood vessel formation and recruit healing responses within tissue. Alongside this sat a newer ecosystem of consumer and clinical technologies: penis pumps for maintaining oxygenation and tissue nourishment, pelvic floor devices that gamified Kegel exercises, vaginal red light therapy, and bio-tracking devices capable of charting orgasmic response.
It was, in one sense, an almost futuristic catalogue of interventions. But Killen’s argument remained rooted in an old truth: tissues that were injured, underused, scarred, or poorly perfused tended not to function well.
From Wearables To Decentralized Science
Killen also cast an eye toward a more distributed future, where sexual health data would no longer be trapped in fragmented medical silos. She spoke with enthusiasm about wearables, app-based tracking, and decentralized science platforms that could aggregate personal experiments, laboratory values, and biometric data.
For a field long shaped by embarrassment, underreporting, and lack of rigorous female-centered measurement, this mattered. New technologies, particularly in women’s sexual health, promised not only treatment but visibility. Metrics once ignored could now be recorded, compared, and studied.
This was, perhaps, one of the more quietly radical notes in the talk. Sexual health had often been excluded from serious biomedical tracking, especially for women. Killen’s vision suggested a future in which intimate function would be measured with the same seriousness as glucose variability, sleep stages, or heart-rate recovery.
A Provocation Wrapped In Practical Advice
There was a provocative confidence to Killen’s presentation, but also a pragmatic streak. Lift heavy weights. Reduce stress. Breathe through the nose. Protect nitric oxide pathways. Investigate hormonal decline rather than normalize it. Consult pelvic floor specialists before using strengthening tools. Use technology when it adds insight, not just novelty.
What made **Sexponential Medicine** memorable at **Biohacker Summit 2022 Amsterdam** was not simply its willingness to speak openly about sex in a longevity setting. It was the way Killen fused the erotic with the clinical, the futuristic with the ordinary. In her telling, sexual health was neither indulgence nor afterthought. It was a biological report card.
By the end, she framed the subject in almost civilizational terms.
“**Sexual health is one of the greatest forms of human connection and one of the greatest drivers of longevity and human optimization known to man,**” Killen said.
For a field obsessed with extending life, her message was difficult to dismiss. A longer life, she suggested, should not be imagined only in years added, diseases delayed, or biomarkers improved. It should also be measured in vitality, connection, circulation, sensation, and the body’s enduring ability to feel fully alive.
