A common question among men is whether an enlarged prostate causes impotence. In fact, no, because the gland does not have a direct relationship with erection. Learn more in today’s text.
To introduce such a delicate subject, it’s important to start this text by making it clear that no: an enlarged prostate cannot cause sexual impotence.
This statement is necessary to debunk a common misconception. Today, we’ll explain better what happens when the prostate is enlarged and why there’s this question about sexual impotence, since there’s no direct relationship between these two aspects.
We’ll address the main related doubts, providing accurate information, in addition to clarifying the fundamental role of the prostate in male sexual health and its influence on different aspects of erectile function and ejaculation. Stay with us!
Can an enlarged prostate cause erectile dysfunction?
If you think an enlarged prostate causes erectile dysfunction, know that the relationship between benign prostatic hyperplasia (BPH) – popularly known as “enlarged prostate” – and erectile dysfunction (sexual impotence) is also uncertain for many men.
Although both problems can significantly impact the quality of life of patients, the association between them is a myth. Besides not being directly related, the symptoms are different.
In general, BPH affects urination, causing symptoms such as difficulty urinating or increased urinary frequency. On the other hand, erectile dysfunction is related to the ability to obtain or maintain an erection for initiating sexual activity.
What causes an enlarged prostate?

The enlargement of the prostate is more common than imagined. According to information from the Brazilian Society of Urology, the condition affects about half of the patients after 50 years, and approximately 90% after 90 years.
A study published in the National Library of Medicine (PubMed) reinforces that benign prostatic hyperplasia is very present in the aging of men in general, and has a histological worldwide prevalence, starting between 40 and 45 years, reaching 60% at 60 years and 80% at 80 years.
Among the main reasons for prostate growth are aging itself, genetics, and the presence of hormonal imbalances.
However, the exact mechanisms leading to prostate growth are not yet confirmed by studies.
Chronic inflammation of the prostate (chronic prostatitis) may also be associated with the development of BPH, although the exact relationship is not fully understood by medicine.
Symptoms to watch out for and associated risks
Among the most common symptoms of BPH are:
- Difficulty urinating;
- Increase in urinary frequency, especially during the night (nocturia);
- Urinary urgency, often resulting in loss of bladder control (urinary incontinence);
- Dribbling after urinating, due to incomplete emptying of the bladder;
- Feeling of a full bladder, even after urinating;
- Pain or discomfort in the pelvic region, back, or perineum (area between the anus and genital organs).
It’s important to emphasize that these signs can also be caused by other conditions, such as urinary tract infections or even prostate cancer. Evaluation by a urologist is essential for diagnosis in all cases.
What is the relationship between the prostate and sexual function?

The prostate plays an important role in male sexual function, although it is not directly involved in the mechanism of erection or orgasm.
Its main function is related to the production of prostatic fluid, which is part of the semen and helps to nourish and transport sperm during ejaculation.
Generally, a healthy prostate is the size of a walnut (about 3cm in height and weighing 20 to 30 grams) and is located just below the bladder, surrounding the urethra, which carries urine from the bladder out of the body.
In younger men, the prostate is usually smaller and remains stable in size. However, with aging, the prostate can gradually increase in size, which we call BPH.
Although the condition can cause urinary symptoms due to compression of the urethra, it is not directly associated with sexual dysfunction.
Do treatments for benign prostatic hyperplasia cause erectile dysfunction?
An enlarged prostate has a cure: in some cases, treatments for BPH, such as medications or surgeries, can affect erectile function. However, this still does not associate the two conditions.
This is due to side effects. There may also be a decrease in male libido or retrograde ejaculation (where semen enters the bladder instead of being ejaculated out of the body).
In this case, if side effects are identified and concerns about erectile function arise, it’s essential to consult a urologist for evaluation and proper guidance.
If the patient has impotence, can it be reversed?
Yes, sexual impotence can be reversible in many cases, and the treatment will depend on the cause. In some situations, just lifestyle changes, such as weight loss, regular exercise, and reducing alcohol and tobacco consumption, can significantly improve erectile function.
When the cause is psychological, therapy is a viable option to assist the man.
In addition, there are medications, such as phosphodiesterase type 5 inhibitors (commercially known as Viagra, Cialis, and Levitra, for example), which are effective when well indicated.
In more complex cases, a multidisciplinary approach involving medical follow-up, a sex therapist, and/or psychologists may be necessary.
Can those with an enlarged prostate have sex?
Yes, people with an enlarged prostate can normally have sexual relations. As we mentioned earlier, BPH is not directly associated with sexual function.
Indirectly, however, the condition can cause urinary symptoms, which can affect the quality of life and potentially interfere with sexual activity.
Can those with an enlarged prostate take Viagra?
Viagra (sildenafil citrate) is a controversial medication. Self-medication can cause serious problems. Therefore, it is important that it be consumed only under medical guidance.
Although it is considered safe for many men with BPH, the doctor will consider, before prescribing, other health problems or medications in use that may pose risks.
Only a doctor can carefully evaluate the situation and determine if Viagra is a safe and appropriate option, on a case-by-case basis.
