Prostatectomy, the surgical removal of the prostate gland, is a common treatment for prostate cancer. While the procedure can be life-saving, it can also lead to side effects such as urinary incontinence and erectile dysfunction (ED). In this article, we will explore the reasons behind ED after prostatectomy and discuss what you need to know about this condition.

Erectile dysfunction, or the inability to achieve or maintain an erection sufficient for sexual intercourse, is a common side effect of prostatectomy. In fact, it is estimated that up to 70% of men experience some degree of ED after the surgery. This can be distressing for both the patient and their partner, and it is important to understand the reasons behind this condition and the available treatments.


Understanding the Prostate


The prostate gland is a small, walnut-shaped organ that sits below the bladder and in front of the rectum in men. Its main function is to produce semen, which is the fluid that carries sperm during ejaculation. The prostate gland is also responsible for regulating urine flow by surrounding the urethra, which is the tube that carries urine from the bladder out of the body.


What is Prostatectomy?


Prostatectomy is the surgical removal of the prostate gland. There are two main types of prostatectomy: radical prostatectomy and simple prostatectomy. Radical prostatectomy is the most common and involves removing the entire prostate gland, seminal vesicles, and some surrounding tissue. Simple prostatectomy, on the other hand, involves removing only the inner part of the prostate gland and is typically done to relieve urinary symptoms caused by an enlarged prostate.


Causes of Erectile Dysfunction after Prostatectomy


There are several reasons why ED can occur after prostatectomy. These include:


Nerve Damage


During prostatectomy, the nerves that control erections may be damaged or removed. These nerves are responsible for sending signals to the penis to initiate and maintain an erection. Damage to these nerves can result in a loss of sensation in the penis or an inability to achieve or maintain an erection.


Blood Supply Disruption


The prostate gland is surrounded by blood vessels that supply blood to the penis during an erection. During prostatectomy, these blood vessels may be damaged or removed, resulting in a disruption of blood flow to the penis. This can lead to difficulties achieving or maintaining an erection.


Psychological Factors


The diagnosis of prostate cancer and the subsequent treatment can be a stressful and emotional experience. This stress can lead to depression, anxiety, and other psychological factors that can contribute to ED.


Treatment for Erectile Dysfunction after Prostatectomy


Fortunately, there are several treatments available for ED after prostatectomy. These include:




Oral medications such as sildenafil (Viagra), tadalafil (Cialis), and vardenafil (Levitra) are often the first line of treatment for ED. These medications work by increasing blood flow to the penis, which can help to initiate and maintain an erection. However, these medications may not be effective for all men, and they can have side effects such as headaches and flushing.


Vacuum Erection Devices


A vacuum erection device (VED) is a non-invasive device that can be used to create an erection. The device consists of a plastic tube that is placed over the penis, and a pump that creates a vacuum inside the tube. This vacuum draws blood into the penis, causing it to become erect. A constriction band is then placed at the base of the penis to maintain the erection.


Penile Injections


Penile injections are another treatment option for ED after prostatectomy. These injections involve the injection of a medication called alprostadil into the penis. Alprostadil works by relaxing the blood vessels in the penis, allowing blood to flow in and create an erection. Penile injections can be effective for up to 80% of men, but they do require a certain level of comfort with self-injection.


Penile Implants


Penile implants are a surgical option for men who have not had success with other treatments. There are two types of penile implants: inflatable and non-inflatable. Inflatable implants consist of two cylinders that are placed inside the penis, a reservoir that is implanted in the abdomen, and a pump that is implanted in the scrotum. Non-inflatable implants consist of a pair of rods that are implanted in the penis. Penile implants can provide a more natural-looking and -feeling erection, but they do require surgery and can have complications such as infection and mechanical failure.




Erectile dysfunction is a common side effect of prostatectomy, but there are several treatments available to help manage this condition. Understanding the causes of ED after prostatectomy and the available treatments can help patients and their partners navigate this difficult aspect of prostate cancer treatment.
