What Do You Call a Penis Doctor?

The doctor who specializes in penis-related health issues is most commonly called a urologist. Urologists are surgeons trained to diagnose and treat conditions of the entire urinary tract and the male reproductive system, including the penis, testicles, and prostate. A more narrowly focused specialist called an andrologist concentrates specifically on male reproductive and sexual health. Depending on the problem, you might also see a sexual medicine specialist, a dermatologist, or a pediatric urologist, but a urologist is the standard starting point for most penile concerns.

Urologist vs. Andrologist

The word “urologist” comes from the Greek root for urine, which can be misleading. Urology covers far more than bladder and kidney issues. Urologists handle erectile dysfunction, penile curvature, infections, trauma, cancer, congenital abnormalities, and surgical procedures like circumcision or penile prosthesis implantation. If you need one specialist for a penile problem and you’re not sure where to start, a urologist is almost always the right call.

An andrologist is a step more specialized. The term comes from the Greek word “andros,” meaning man. Andrologists focus on conditions unique to male biology: infertility, hormone deficiency, erectile dysfunction, and ejaculatory disorders. Some andrologists are urologists who completed extra fellowship training in male reproductive medicine. Others come from an endocrinology background, particularly when hormone management is the main concern. Andrology is well established as a subspecialty in Europe and parts of Asia, but in the United States, the distinction is less commonly recognized by the public. Most American men who need andrological care end up seeing a urologist with a subspecialty interest in male infertility or sexual medicine.

Other Specialists Who Treat Penile Conditions

Not every penile problem calls for a urologist. Some conditions sit squarely in another specialist’s territory, and knowing which door to walk through can save time.

Dermatologist: Skin conditions that affect the penis, such as lichen sclerosus, psoriasis, balanitis, or genital warts, often start with a dermatologist. Lichen sclerosus is a chronic inflammatory skin disease that can cause scarring and tightening of the foreskin or urethral opening. When it progresses to the point of causing urethral strictures, a urologist typically takes over. In one series of lichen sclerosus patients, the majority needed circumcision, and a subset with strictures required reconstruction using tissue grafts from the inner cheek.¹
Sexual medicine specialist: These physicians may be urologists, psychiatrists, endocrinologists, or gynecologists who have additional training in sexual dysfunction. They manage conditions like erectile dysfunction, low desire, premature ejaculation, and the psychological dimensions of sexual health.
Pediatric urologist: Children born with congenital penile conditions such as hypospadias (where the urethral opening is on the underside of the penis rather than the tip) are referred to a pediatric urologist, who has surgical training specific to growing anatomy.
Oncologic urologist: Penile cancer is rare, but when it occurs, an oncologic urologist or surgical oncologist with urologic expertise manages the treatment, which can range from local excision to partial or radical penectomy.²
Reconstructive urologist: Surgeons who specialize in rebuilding urethral and penile structures, whether after trauma, failed earlier surgeries, or as part of gender-affirming procedures like phalloplasty.³

In practice, many of these roles overlap. A urologist with a sexual medicine fellowship might manage both erectile dysfunction and Peyronie’s disease. A pediatric urologist handles hypospadias surgery but may also treat phimosis in an adolescent. The medical system is less neatly divided than these categories suggest, but knowing the subspecialty names helps when you’re searching for the right provider or asking for a referral.

Common Conditions a “Penis Doctor” Treats

Erectile dysfunction is the most common reason men see a specialist for a penile concern, but it is far from the only one. Here is a sampling of the conditions that bring people through the door:

Peyronie’s disease is a fibrotic condition in which scar tissue, called plaque, forms in the tough outer layer of the penis. Over time, the plaque can cause curvature, pain during erections, and difficulty with intercourse. Research into potential treatments is active. One animal study found that a drug called mycophenolate mofetil helped restore the normal collagen balance in penile tissue after Peyronie’s-like damage was induced in rats, suggesting a possible future treatment pathway.⁴ Current standard treatments include injectable medications, penile traction devices, and in severe cases, surgery.

Priapism is a prolonged erection unrelated to sexual arousal. The ischemic form, where blood is trapped in the erectile tissue without fresh oxygen, is a medical emergency. Left untreated for more than four hours, it can permanently damage the erectile tissue and lead to lasting erectile dysfunction.⁵ Treatment involves draining blood from the penis and injecting a medication like phenylephrine to constrict the blood vessels. Research has found that even relatively high doses of this injection can be given safely without significant effects on blood pressure or heart rate.⁶

Hypospadias is one of the most common congenital conditions affecting the penis. Surgery to reposition the urethral opening is routinely performed in childhood, often before age one, though complications like fistulas and narrowing of the opening are well documented. For milder cases where the opening is only slightly displaced, the decision to operate is less straightforward. Evidence suggests that adults with uncorrected mild hypospadias often report good sexual and urinary function, which has prompted some surgeons to question whether early surgery is always beneficial for distal cases.⁷ More severe forms, where the opening is located partway along the shaft or near the base, almost always require surgical correction.

How These Specialists Investigate Penile Problems

Diagnosis goes well beyond a physical exam. One of the most important tools in a penile specialist’s arsenal is Doppler ultrasound, which uses sound waves to measure blood flow through the arteries and veins of the penis. This test is the go-to method for figuring out whether erectile dysfunction has a vascular cause, meaning a problem with blood flow in or out.⁸

During the procedure, a medication is injected into the penis to trigger an erection in a controlled setting, and then a handheld ultrasound probe measures how quickly blood flows in and how well the veins prevent it from flowing back out. The same imaging technique is also used to evaluate Peyronie’s disease and priapism.⁹ One study found that men who failed to reach their full stretched penile length after the injection were more than twice as likely to have a specific type of vascular problem called veno-occlusive dysfunction, where blood leaks out of the erectile tissue too quickly.¹⁰

Beyond imaging, evaluation may include blood tests for hormone levels and diabetes markers, nocturnal penile tumescence testing (which checks whether erections happen normally during sleep), questionnaires about sexual function, and psychological screening. The specific workup depends on the presenting problem. A man with a painless lump and a curved erection gets a different workup from a teenager with an abnormal urethral opening.

When Erectile Dysfunction Needs More Than a Prescription

For many men, erectile dysfunction begins with a prescription for a medication like sildenafil (Viagra) or tadalafil (Cialis) from a primary care doctor. That is a perfectly reasonable first step. But when pills don’t work well enough, or when the cause is more complicated than simple blood flow, a specialist becomes important.

Psychological factors play a bigger role than many people assume. Performance anxiety, relationship conflict, depression, and a history of sexual trauma can all drive erectile problems even when the blood vessels and nerves are working fine. A pilot study found that combining sildenafil with cognitive-behavioral sex therapy produced better erectile function and higher satisfaction rates than sildenafil alone. After the initial treatment phase, about half the men in the combined group met success criteria for erectile function, compared to less than a third of men taking the medication by itself.¹¹ This is a small study, but it illustrates why a specialist who understands both the physical and psychological dimensions of sexual health can offer something a pill alone cannot.

When medications and therapy are not enough, the next tier of treatment includes vacuum erection devices, penile injections, and penile prosthesis implantation. The prosthesis option is a surgical procedure, most often involving a three-piece inflatable device implanted inside the penis and scrotum. It is typically reserved for men who have exhausted other options. A recent study of men with inflatable penile prostheses found that self-reported sensory loss, rather than the specific surgical technique, was the main factor associated with lower sexual satisfaction after the procedure.¹²

Why Men Avoid Going

A significant barrier to penile health care is embarrassment. Conditions involving the genitals carry a layer of social stigma that kidney stones or a sprained ankle do not. A review of stigma in urology found that the societal taboo around discussing urologic conditions creates an environment where people hesitate to seek professional help, sometimes for years.¹³ Erectile dysfunction, sexually transmitted infections, penile curvature, and concerns about penis size are all topics men frequently avoid raising with their doctors.

This avoidance has real consequences. Erectile dysfunction, for instance, is often an early warning sign of cardiovascular disease. The blood vessels in the penis are smaller than those feeding the heart, so they tend to show damage first. A man who avoids seeing a doctor about erectile problems might miss a chance to catch and manage heart disease risk factors years before a cardiac event.

There is also a safety dimension to avoidance. Some men turn to unregulated sexual enhancement supplements instead of seeing a doctor. Many of these products contain undeclared pharmaceutical ingredients, sometimes at unpredictable doses, and without the warnings about dangerous drug interactions that legitimate prescriptions include. Beyond the direct risk of the product itself, skipping the doctor’s visit means skipping the screening for underlying conditions like diabetes, high blood pressure, or hormonal imbalances that often accompany erectile dysfunction.¹⁴

How to Find the Right Specialist

If you are starting from scratch and your primary care doctor cannot resolve the issue, the standard path is a referral to a general urologist. From there, if the problem requires more specialized expertise, the urologist can point you toward a fellowship-trained sexual medicine specialist, a microsurgeon for fertility issues, or a reconstructive urologist for structural problems.

Professional societies can help you find credentialed providers. The American Urological Association (AUA) and the Sexual Medicine Society of North America (SMSNA) both maintain directories. For fertility-specific concerns, the American Society for Reproductive Medicine lists andrologists and reproductive urologists. In the UK and much of Europe, andrology is more formally recognized as a distinct clinical discipline, so searching specifically for an andrologist is more straightforward.

When choosing a provider, it is reasonable to ask about their fellowship training, how frequently they perform the procedure you need, and whether they work as part of a multidisciplinary team. A urologist who regularly places penile prostheses will have different complication rates than one who does it a few times a year. Similarly, a hypospadias repair is best done by a surgeon who specializes in it, not by a general urologist who occasionally takes on pediatric cases.

Testosterone Therapy and the Hormonal Side

Low testosterone, sometimes called hypogonadism or testosterone deficiency, is another condition that falls under the penile-health umbrella because of its effects on erectile function and libido. Testosterone therapy in men with genuine deficiency has been shown to improve sexual function, body composition, bone density, and quality of life.¹⁵

The specialist managing testosterone replacement may be an endocrinologist, a urologist, or an andrologist. The choice depends partly on the underlying cause. If low testosterone is driven by a pituitary problem, an endocrinologist is the better fit. If it is related to testicular injury or age-related decline and the patient also has sexual dysfunction, a urologist or sexual medicine specialist who can manage both the hormones and the downstream symptoms is often more practical.

Testosterone therapy is not without trade-offs. It can suppress sperm production, which matters if you want to have children. It requires ongoing monitoring of blood counts, prostate health, and cardiovascular markers. The “low T” advertising campaigns of the last two decades have made testosterone therapy seem simpler and more universally beneficial than the evidence supports. A thoughtful specialist will check your levels carefully, rule out other causes, and have an honest conversation about what treatment can and cannot do before reaching for the prescription pad.

Gender-Affirming Penile Surgery

Reconstructive urologists are increasingly involved in gender-affirming surgeries, particularly phalloplasty (construction of a penis) and metoidioplasty (release and enhancement of a testosterone-enlarged clitoris) for transgender men and nonbinary individuals. These are complex, multi-stage procedures. One of the most challenging aspects is constructing a functional urethra through the new anatomy. Urethral strictures, which are narrowings that block urine flow, are a known complication. A study of stricture repairs after gender-affirming phalloplasty and metoidioplasty documented the surgical outcomes of urethroplasty in this patient population, highlighting the particular anatomic region of the new urethra most prone to scarring.³

Finding a surgeon with specific expertise in gender-affirming penile procedures is important. Not every urologist is trained in these techniques, and the complication and revision rates vary significantly with surgical volume. Multidisciplinary teams that include mental health professionals, endocrinologists, and experienced reconstructive surgeons tend to produce the best outcomes. If you are exploring these options, organizations like the World Professional Association for Transgender Health (WPATH) can help identify qualified surgical teams.

What a Visit Actually Looks Like

If you have never been to a urologist or andrologist for a penile concern, knowing what to expect can reduce some of the anxiety. The visit typically starts with a detailed medical and sexual history. You’ll be asked about the onset, duration, and nature of your symptoms, your medications, your cardiovascular health, and your sexual history. Be honest. Doctors in this field hear every version of every concern, and withholding information only makes diagnosis harder.

A physical examination follows. For penile complaints, this includes inspection and palpation of the penis, foreskin, and testicles. It is brief and clinical. If imaging is needed, a Doppler ultrasound may be scheduled for a follow-up visit rather than performed on the spot. Blood work for hormones, glucose, and cholesterol is standard when erectile dysfunction is the presenting issue.

The visit may end with a treatment plan, a referral to a more specialized provider, or a request for additional testing. Many men are pleasantly surprised to learn that their problem has a straightforward explanation and a well-established treatment. Conditions that feel uniquely embarrassing from the patient’s perspective are routine from the specialist’s side of the desk.
