Sexual activity may promote kidney stone passage by increasing urine flow and aiding ureteral relaxation.
Understanding Kidney Stones and Their Passage
Kidney stones are hard mineral and salt deposits that form inside the kidneys. These crystalline masses can vary in size, from tiny grains to larger stones several millimeters wide. When a stone moves from the kidney into the ureter—the narrow tube connecting the kidney to the bladder—it can cause intense pain and discomfort. The process of passing a kidney stone involves the stone traveling through this narrow passage, eventually exiting the body through urination.
The journey isn’t always smooth. Stones can get lodged in the ureter, causing blockages, swelling, and significant pain known as renal colic. Physicians often recommend hydration, pain management, and sometimes medical procedures depending on the stone’s size and location.
But what role does sexual activity play in this process? Can sex help pass a kidney stone? This question has intrigued patients and healthcare providers alike.
The Physiology Behind Kidney Stone Passage
To appreciate how sex might aid in passing a kidney stone, it’s essential to understand the physiological mechanisms involved in ureteral function.
The ureter is lined with smooth muscle fibers that contract rhythmically—a process called peristalsis—to propel urine from the kidneys to the bladder. These contractions also help move any small stones along. However, when stones are too large or irregularly shaped, they can irritate or obstruct the ureter, causing spasms and pain.
Relaxation of these muscles can facilitate easier passage of stones by reducing spasms and widening the ureter slightly. Increasing urine flow also helps flush out smaller particles or fragments.
Sexual activity triggers various physiological responses that could influence these factors:
- Increased blood flow: Sexual arousal causes vasodilation, increasing blood flow to pelvic organs.
- Ureteral relaxation: Certain hormones released during sex may relax smooth muscles.
- Enhanced urine production: Sexual stimulation may indirectly promote hydration behaviors or minor hormonal changes affecting urine output.
These effects suggest a plausible connection between sexual activity and facilitating kidney stone passage.
Scientific Evidence on Sex and Kidney Stone Passage
Research specifically focusing on whether sex helps pass kidney stones is limited but growing. A few studies have explored how physical activity influences stone movement, with some mentioning sexual intercourse as a potential aid.
One notable study published in 2016 investigated whether sexual intercourse could serve as a non-invasive treatment for distal ureteral stones (stones located closer to the bladder). Researchers hypothesized that nitric oxide released during sexual activity might relax ureteral smooth muscles similarly to certain medications like alpha-blockers.
The study involved two groups of patients with small distal ureteral stones: one group was advised to engage in regular sexual intercourse (three times per week), while the control group received standard care without specific recommendations about sex. Results showed that patients who had regular sexual activity passed their stones faster and experienced less pain compared to controls.
While this study offers promising insights, more extensive clinical trials are needed to confirm these findings definitively. The mechanisms behind how sex aids stone passage remain under investigation but likely involve muscle relaxation and increased urine flow.
How Nitric Oxide Plays a Role
Nitric oxide (NO) is a powerful vasodilator produced naturally in the body during sexual arousal. It relaxes vascular smooth muscle cells, allowing blood vessels to widen. Interestingly, NO also impacts other smooth muscles, including those lining the ureters.
Medications like tamsulosin—commonly prescribed for kidney stone passage—work by relaxing ureteral muscles through alpha-adrenergic blockade, reducing spasms and easing stone movement. Nitric oxide produced during sex may have a similar relaxing effect on these muscles, potentially explaining why sexual activity could assist in passing stones.
Physical Activity vs Sexual Activity: Which Helps More?
Physical movement is often recommended for patients with small kidney stones because it promotes mechanical jostling that may dislodge or move stones along. Activities such as walking or jogging increase gravity’s effect on stones within the urinary tract.
Sexual intercourse combines physical exertion with specific physiological responses like hormone release and muscle relaxation. This combination might provide unique benefits beyond simple exercise:
| Factor | Physical Activity | Sexual Activity |
|---|---|---|
| Muscle Relaxation | Minimal direct effect on ureteral muscles | Releases nitric oxide; promotes relaxation |
| Increased Urine Flow | Possible if hydration accompanies activity | Mild hormonal effects; encourages hydration behavior |
| Pain Relief | No direct analgesic effect | Mediated by endorphins released during orgasm |
| Mechanical Jostling of Stones | High impact activities promote movement | Moderate physical movement during intercourse possible but variable |
This table highlights how sexual activity might uniquely benefit those trying to pass kidney stones compared to other forms of exercise.
The Pain Factor: Can Sex Ease Kidney Stone Discomfort?
One of the most agonizing symptoms of kidney stones is severe flank pain caused by spasms in the ureter as it tries to expel an obstructing stone. Managing this pain often requires analgesics or even emergency care.
Sexual activity triggers endorphin release—natural painkillers produced by the brain—which can reduce pain perception temporarily. Additionally, orgasms cause muscle contractions followed by relaxation phases that might ease tension in pelvic muscles surrounding the urinary tract.
While engaging in sex during an acute kidney stone attack might be challenging due to discomfort levels, mild sexual stimulation or intimacy could offer some relief for those with smaller or less painful stones waiting for spontaneous passage.
Cautions About Sexual Activity During Kidney Stone Episodes
Despite potential benefits, caution is warranted:
- If pain is severe or accompanied by fever, nausea, vomiting, or blood in urine, immediate medical attention is necessary.
- Avoid forcing sexual activity if discomfort prevents it; pushing through intense pain could exacerbate symptoms.
- Consult your healthcare provider before using sex as part of your management strategy.
- Avoid vigorous intercourse if there’s any risk of infection or injury related to urinary tract issues.
Sex should complement medical advice rather than replace established treatments like hydration therapy or prescribed medications.
The Role of Medical Intervention When Stones Don’t Pass Naturally
Not all kidney stones will pass spontaneously despite best efforts including sex or lifestyle changes. Larger stones (greater than 6 millimeters) often require medical intervention such as:
- Lithotripsy: Using shock waves to break up stones into smaller pieces easier to pass.
- Ureteroscopy: Inserting a thin scope via urinary tract to remove or fragment stones directly.
- Surgery: Rarely needed but considered when other methods fail or complications arise.
If you experience persistent symptoms beyond several weeks without improvement—or worsening signs like fever—seek prompt evaluation from a urologist.

Frequently Asked Questions
Can sex help pass a kidney stone by increasing urine flow?
Sexual activity may promote increased urine flow due to physiological responses like vasodilation and hormonal changes. This enhanced urine production can help flush out smaller kidney stones, potentially aiding their passage through the urinary tract.
Does sexual activity relax the ureter to assist in passing kidney stones?
During sex, hormones released can relax smooth muscles, including those lining the ureter. This relaxation might reduce spasms and widen the ureter slightly, making it easier for kidney stones to pass through.
Is there scientific evidence supporting sex as a method to pass kidney stones?
Research on this topic is limited but growing. Some studies suggest that physical activity, including sexual activity, may help facilitate stone passage by promoting muscle relaxation and urine flow, though more research is needed for conclusive proof.
How does sexual arousal affect the physiology related to kidney stone passage?
Sexual arousal causes vasodilation, increasing blood flow to pelvic organs and potentially triggering smooth muscle relaxation in the ureter. These changes can contribute to easier movement of kidney stones along the urinary tract.
Should sexual activity be considered a treatment option for passing kidney stones?
While sex may aid stone passage through physiological effects, it is not a standalone treatment. Patients should follow medical advice including hydration and pain management, using sexual activity as a complementary approach if appropriate.
The Bottom Line – Can Sex Help Pass A Kidney Stone?
Sexual activity has potential benefits that may aid natural kidney stone passage by promoting smooth muscle relaxation via nitric oxide release, increasing pelvic blood flow, encouraging mild physical movement, and providing temporary pain relief through endorphin release. While scientific evidence remains limited but promising for small distal ureteral stones specifically, incorporating consensual sex alongside hydration and lifestyle modifications could improve comfort and accelerate stone expulsion for some individuals.
That said, severe symptoms require immediate medical attention rather than relying solely on home remedies including sexual activity. Always discuss your condition openly with healthcare professionals before attempting alternative approaches.
Ultimately, Can Sex Help Pass A Kidney Stone? the answer leans toward yes—but it’s just one piece of an effective management puzzle involving hydration, diet control, medical guidance, and patience.
