Left untreated, Peyronie’s disease follows a fairly predictable two-phase course: an active inflammatory phase lasting roughly 12 to 18 months, followed by a stable chronic phase where the scar tissue hardens and the curvature locks in. The good news is that the condition isn’t dangerous in a life-threatening sense, and some men do see improvement on their own. But waiting it out carries real risks, from worsening curvature to erectile problems to narrowing your future treatment options.
The Two Phases of Untreated Peyronie’s
Peyronie’s disease starts with an active phase driven by inflammation inside the tough tissue surrounding the penis. During this window, you may notice pain during erections, a developing curve, or changes in shape like shortening or narrowing. Pain is reported by 20% to 70% of men in this phase and typically fades within 12 to 18 months as inflammation dies down. The curvature, however, tends to stabilize or worsen during this same period.
Once the inflammation settles, the disease enters its chronic phase, usually around 12 to 18 months after onset, though some men reach this point as early as 5 to 7 months. Pain generally resolves. The scar tissue (plaque) becomes firmer, and in some cases it calcifies into a hard deposit. Penile deformity stabilizes, but it rarely improves on its own during this second phase.
How Often Curvature Improves, Stays, or Worsens
One of the biggest questions men have is whether the curve will get better by itself. The answer depends on which data you look at and over what timeframe. A long-term survey following men for a median of 8.4 years found that about 43% perceived some improvement in curvature, 37% stayed the same, and 20% got worse. That’s more optimistic than older estimates, which put spontaneous improvement at just 8% to 12% of cases.
The takeaway: while a meaningful number of men do see some natural improvement over years, the majority either stay the same or get worse. There’s no reliable way to predict which group you’ll fall into, which makes a “wait and see” approach something of a gamble.
Erectile Dysfunction
Erectile problems are common alongside Peyronie’s disease, showing up in anywhere from 22% to 54% of men during the active phase. The relationship between the two conditions runs in both directions. The scar tissue itself can interfere with the way blood fills and stays trapped in the penis during an erection. At the same time, many of the risk factors that contribute to erectile dysfunction (diabetes, obesity, smoking, high cholesterol) are also significantly associated with Peyronie’s. The longer erectile dysfunction persists alongside untreated Peyronie’s, the more severe it tends to become.
Psychological and Relationship Effects
The mental health burden of living with untreated Peyronie’s is substantial and often underestimated. Studies put the prevalence of depression in men with the condition between 12% and 62%, with most estimates landing around 15% to 27%. Anxiety rates range from 7% to 75%, depending on the study and population. Low self-esteem, emotional distress, and reduced quality of life are consistently reported.
Being in a committed relationship appears to offer some protection. One study found that having a partner roughly halved the odds of depression, and men with higher self-esteem and stronger relationship satisfaction scores also fared better psychologically. But Peyronie’s doesn’t affect just one person. Research on female partners found that untreated curvature contributed to pain during intercourse, loss of sexual desire, difficulty reaching orgasm, and overall sexual dissatisfaction. Researchers have described the resulting dynamic as a “couple’s pain,” where both partners experience physical discomfort and the sexual relationship deteriorates in a cycle that reinforces itself.
How Waiting Can Limit Treatment Options
Perhaps the most concrete consequence of leaving Peyronie’s untreated for years is what happens to the plaque itself. Over time, scar tissue can calcify, turning from a firm, fibrous deposit into something harder and more rigid. This matters because calcified plaques are specifically excluded from the eligibility criteria for injection-based treatments. The American Urological Association notes that the main injection therapies have only been studied in men without calcified plaques and with curvature between 30 and 90 degrees. If your plaque calcifies, those less-invasive options are essentially off the table, and surgery becomes the primary path forward.
Surgery itself isn’t available during the active phase. The AUA recommends that men be in the stable phase, with unchanging curvature for at least 3 to 6 months, before surgical reconstruction is considered. So there’s a built-in waiting period regardless. But there’s a difference between monitored waiting during the active phase and years of avoidance that allow the plaque to harden beyond the reach of nonsurgical treatments.
What “Stable” Doesn’t Mean
It’s worth clarifying what happens when the disease stabilizes on its own. Stabilization means the curvature and plaque stop changing. It does not mean they go away. Most men who reach the chronic phase without treatment are left with a permanent curve, a palpable hard spot, and some degree of shape change. If the curvature is mild (under 30 degrees) and doesn’t interfere with sexual function, that may be perfectly livable. For men with more significant deformity, stabilization simply means the problem has stopped getting worse, not that it’s resolved.
The chronic phase also doesn’t protect against continued erectile difficulties. Even after pain resolves and the curve stops progressing, the structural changes in the penis and any underlying vascular issues remain. Men who had erectile problems during the active phase often continue to experience them unless those issues are addressed separately.
