While it’s typical for men to experience erections in their sleep, it usually occurs without disturbing them. However, for a small percentage of men, nighttime erections are a painful and anxiety-inducing experience. Occasionally, this can affect men with Peyronie’s disease as well. The main distinction between some of the men who have sleep-related painful erections (SRPE) and Peyronie’s disease is that they don’t have any deformities of the penis. They also don’t experience painful erections when awake. Nevertheless, both conditions can exist simultaneously.
Although SRPE may have been around for years, there still isn’t much information about its causes. However, according to a 2021 narrative review, a combination of factors may contribute to its development. When analyzing the data available at the time, researchers concluded that SRPE was mainly caused by obstructive sleep apnea (OSA), higher testosterone levels, compartment syndrome in the penis, psychological issues, a lower threshold for pain in REM sleep, and regulation of the neuroendocrine system.
With OSA, you’re dealing with a sleep disorder in which something is obstructing your airway and disturbs your sleep. The issue may be caused by a complete or partial collapse of the upper airway, followed by decreased oxygen levels (hypoxia) and activation of the sympathetic nervous system. Hypoxia can then lead to increased blood flow that has multiple effects on the body, like an erection.
While you don’t necessarily need high levels of testosterone to have an erection while awake, there’s some research to suggest that higher levels of the hormone at night are related to having an erection. Of course, this needs further study.
In penile compartment syndrome, researchers suggest that an overly full bladder may stimulate the erectile center and result in a continuous erection. Additionally, a full bladder may cause inflammation that leads to the pain associated with the erection. If other organs, such as the prostate and urethra, are swollen, this can block the return of deoxygenated blood to the heart and result in penile compartment syndrome. If this happens, a painful erection may be persistent.
There may also be a link between 5-hydroxytryptamine (5-HT) or serotonin and the occurrence of SRPE. Serotonin plays a role in multiple processes in the body, including acting on vascular smooth muscle cells found in the penis. While this needs a bit more research, the possibility of an association is further suggested by the fact that using selective serotonin reuptake inhibitors (SSRIs) can prevent erections at night.
Researchers would also like to explore the correlation between mental health and SRPE. One study compared the psychological distress of participants who had SRPE and those who had psychogenic erectile dysfunction. Interestingly, those who had SRPE showed more distress than the participants with erectile dysfunction. Generally, this distress is connected to the anxiety that can happen with how SRPE affects the quality of life and mental health of people with this condition.
The link between pain levels and SRPE is another avenue that researchers would like to explore. When looking at other conditions, like migraines, researchers found that changes during sleep may affect how pain is perceived. There is also a cyclical relationship between poor sleep and the perception of pain. Painful conditions can disrupt sleep, and poor sleep can influence your pain threshold. In any case, more work is needed to establish a link.

In addition to more research into the causes of SRPE, more studies are needed to develop an effective treatment regimen. Still, there are a few options. While dealing with it, there are also ways you can handle the pain if it happens. It may help to try urinating, as this may reduce the erection and its resulting pain.
However, it usually takes medical intervention to fully manage SRPE. Generally, using a CPAP machine can help address OSA and may improve sleep. Medications like REM inhibitors and Baclofen have also been shown to be effective in treating SRPE. In a 2024 study, researchers also assessed the use of sodium oxybate to treat the condition. Although this study included only one person, his case caught their interest because he didn’t respond to other possible treatments. It should be noted, though, that this drug is usually used to treat narcolepsy and isn’t an approved treatment for SRPE. As such, your doctor will need to discuss the potential side effects.
The study further highlighted that there’s no ‘one size fits all’ treatment program for SRPE. While some medications have proven effective, it doesn’t mean that researchers should close the door on finding alternatives. That’s why it’s important to talk to your doctor about your symptoms and how any medications may help.

When talking to your doctor about your symptoms, providing detailed information will be key. It may seem daunting at first, but try to write down how often you experience painful erections during sleep. It can also help to record the level of pain, how long it lasts, what helps to ease the pain, and any measures you take to get back to sleep. Noting all the medications you take can also prove useful.
Since more data is needed to fully understand SRPE, it may also help your doctor if you document how conditions may differ from one night to the next. Are there any differences between the nights when you have a painful erection and the ones you don’t? For example, were you more active during the day? Did you take a nap? Were you feeling more relaxed? Did you take anything to help you sleep? All the information you provide can help your doctor paint a more accurate picture of the situation.
Additionally, feel free to do your own research using trusted sources. Doing so can make conversations about managing the condition easier. It’s also important to note that you shouldn’t treat this as a singular conversation. As you move forward with tests to confirm your diagnosis and even further to treatment, you still need to communicate what’s happening.
You should let your doctor know if there were any issues with diagnostic tests, as the diagnostic process is still evolving. At the very least, your doctor may try to rule out priapism, which is an abnormally prolonged and painful erection. Depending on the situation, this can be a single occurrence or a repeated one.
Currently, as part of an SRPE diagnosis, you may need to undergo a sleep study to see what happens at night. However, the first one may not go according to plan. According to one person’s account, undergoing his first sleep study didn’t have the expected results because he had trouble falling asleep in a strange environment. That’s something you’d need to discuss with your doctor as well, because that situation may mean you need to be reassessed.
Once you get to the point of being prescribed medication, you should discuss possible side effects and whether there’s anything you need to change about your current medication regimen. You should also let your doctor know if the drugs you’re taking aren’t effective for managing your symptoms. As long as you keep the lines of communication open, you should be able to work together to determine an effective treatment plan.
Even if you’re already working with a doctor to manage your symptoms, there may be circumstances where you have to seek emergency care. Although they are two distinct conditions, some people with SRPE can also develop what is known as stuttering priapism (SP). This is an emergency condition in which a painful erection lasts for more than four hours. When this happens, blood can’t enter or leave the penis, resulting in a hard shaft but a soft tip. SP needs to be treated by a physician, so it’s critical that you get emergency care immediately. While your treatment options may vary, the doctor may opt to watch what happens, drain the excess blood using a needle, inject medication into the penis to improve blood flow, or surgically insert a shunt to vent the excess blood.
If you’re already dealing with the symptoms of Peyronie’s disease, having painful erections that wake you up may take a toll on your mental health. Fortunately, you don’t have to live that way. While more research is needed on the causes and full range of treatment options for SRPE, some effective options are available. Talk to your doctor as soon as possible so you can get the medical attention you need.
