The degrees of erectile dysfunction can be classified as mild, moderate and severe. Determining the most appropriate treatment depends on the symptoms and possible causes, requiring specialized medical evaluation.
The erectile dysfunction is characterized by the persistent difficulty achieving or maintaining an erection sufficient for sexual activity. Isolated episodes can occur and do not necessarily mean there is a persistent condition. Although the condition is more frequent with aging, young men can also experience erection problems related to physical factors, psychological factors, or a combination of these.
The urologist can investigate the possible causes of erection difficulty, identify the degree of severity and check for the existence of health conditions or psychological factors that contribute to impairment of erectile function. Based on this analysis, it is possible to define the most appropriate treatment.
Why you should read:
- Erectile dysfunction can occur across different age ranges. A study published in 2025 identified some degree of the condition in 50.1% of the men evaluated in Bauru (SP). The interpretation of this number should consider the characteristics of the sample and the criteria used in the research.Consult the original study to learn about its methods and results.
- Not every erection difficulty indicates a severe condition. Knowing the different degrees helps to understand the problem.
- There are treatments for different levels of dysfunction, depending on the cause and clinical conditions.
- A specialized evaluation helps identify the degree of the problem and the available treatment options.
- Understand how the evaluation of erectile dysfunction can be performed and which approaches may be considered according to the characteristics of each case.
What are the degrees of erectile dysfunction?
The degrees of erectile dysfunction are divided into: mild, moderate and severe. Below, learn their characteristics:
- Mild: slight difficulty obtaining or maintaining an erection sufficient for sexual activity;
- Moderate: more marked or recurrent difficulty achieving or maintaining an erection, with possible impact on sexual activity;
- Severe: marked impairment of erectile function, with great difficulty or inability to obtain or maintain an erection sufficient for sexual activity.
These descriptions should not be used as a self-diagnosis tool. Medical evaluation takes into account the patient’s health and sexual history, the characteristics of the symptoms and their impact on erectile function.
The urologist may also use validated questionnaires, such as the International Index of Erectile Function (IIEF) or its abbreviated version, the SHIM (Sexual Health Inventory for Men), to assess sexual function and help classify severity. 
What is mild erectile dysfunction?
The mild erectile dysfunction is the slight difficulty in achieving or maintaining penile rigidity during sexual activity. This change may occur occasionally or in certain situations, without necessarily compromising all sexual encounters. Even when the difficulty seems minor, its persistence warrants investigation.
Changes in erectile function may be related to physical factors, such as cardiovascular diseases and hormonal changes, to psychological issues, or to a combination of these factors. Medical evaluation helps to identify the possible causes and check whether there are health conditions that require follow-up.
Not all cases progress to more severe degrees, but investigation allows for discussing appropriate care and treatments. 
What treatments are indicated for each of the degrees of erectile dysfunction?
The treatment of erectile dysfunction must be individualized, considering the possible causes of the erection difficulty and the presence of associated health conditions, such as diabetes, hypertension, hormonal changes, among others. Factors such as contraindications to certain medications, responses to previous treatments, and the patient’s preferences.
Medication treatment for erectile dysfunction: addressing degrees of erectile dysfunction
Medication treatment may include phosphodiesterase type 5 (PDE5) enzyme inhibitors, such as sildenafil and tadalafil. These medications do not produce an automatic erection; they only facilitate the erectile response in the presence of sexual stimulation. PDE5 inhibitors have demonstrated efficacy in certain clinical situations, but they are not suitable or safe for all patients.
Their use should take into account contraindications, drug interactions, and individualized clinical assessment. The use of nitrates is an important contraindication for PDE5 inhibitors, due to the risk of a significant drop in blood pressure.
Other contraindications, drug interactions, and clinical conditions should also be considered, in accordance with the recommendations of the EAU (European Association of Urology) and with the assessment of the healthcare professional.
Injectable treatment for erectile dysfunction
Intracavernous injection treatment consists of applying medications directly into the corpora cavernosa of the penis, structures responsible for rigidity during erection.
This alternative may be considered in different situations, including when oral medications do not provide satisfactory results or are contraindicated. Indication also depends on clinical characteristics and the patient’s preferences, following medical evaluation.

The active ingredient and dose are defined by the urologist, considering health history and individual response. In some cases, a combination of medications. Regardless of the chosen formulation, the patient needs to receive guidance on the application technique, the prescribed dose, and follow-up. Possible adverse effects include pain at the application site, bruising, and priapism.
The priapism is a prolonged erection that persists for four hours or more and requires urgent medical care. Delay in care can cause damage to penile tissue.
Surgical treatment for erectile dysfunction
Penile prosthesis is one of the surgical treatment options for erectile dysfunction. It may be considered when other alternatives do not provide sufficient benefit, are contraindicated, or when, after discussing risks, benefits and alternatives, the patient chooses this treatment. There are two types of prostheses: malleable and inflatable.
The malleable model keeps the penis in a semi-rigid state, allowing manual positioning for sexual activity. The inflatable model, on the other hand, allows control of the erection through its own mechanism. The benefits, limitations and choice of device should be discussed between the doctor and the patient.
In some cases, it may be necessary to perform a penile reconstruction procedure associated with the penile prosthesis. This may occur when there is pronounced curvature or anatomical changes resulting from Peyronie’s disease, which can compromise penile alignment and function.
The degrees of erectile dysfunction help to understand the severity of erection difficulties, but do not alone determine the choice of treatment. Investigating the causes and associated health conditions is essential to guide management. If you have persistent difficulty obtaining or maintaining an erection, consult a urologist.
The evaluation allows understand the clinical picture, including the degrees of erectile dysfunction and discuss treatment options.
