Oftentimes, men notice changes in urination and sexual performance as they get older.
Two of the most common concerns are an enlarged prostate and erectile dysfunction (ED). Because they often show up around the same stage of life, men often wonder, "Can an enlarged prostate cause ED?"
How the Prostate Changes with Age
The prostate is a small gland located just below the bladder. It surrounds the urethra, which is the tube that carries urine out of the body. Its primary role is to produce fluid that helps transport sperm.
Over time, the prostate can grow larger due to normal cell growth, which can narrow or partially block the urethra. The medical name for this is benign prostatic hypertrophy (BPH), and it can result in urinary symptoms such as:
- A weak or slow urine stream
- Difficulty starting urination
- Frequent urination, especially at night
- Feeling that the bladder is not completely empty
- Dribbling after urination
Understanding Erectile Dysfunction
ED happens when a man cannot get or maintain an erection firm enough for sexual activity. Common causes of erectile dysfunction include:
- Reduced blood flow to the penis, often from clogged or narrowed arteries
- Nerve damage from diabetes, injury, or pelvic surgery
- Hormonal changes, such as low testosterone
- Stress, anxiety, or depression
- Side effects from certain medications
- Past treatments for prostate cancer, including surgery or radiation
While ED becomes more prevalent with age, it’s not something you have to accept as part of getting older.
Can An Enlarged Prostate Cause ED?
BPH itself doesn’t directly cause erectile dysfunction. They are separate conditions but may share some contributing factors. The two often occur together because:
- They share risk factors, including the natural changes that come with aging
- The discomfort of urinary symptoms, like leakage and interrupted sleep, can interfere with intimacy and reduce sexual interest
- Some BPH medications and procedures can affect ejaculation or libido
Another Cause of Prostate Enlargement
BPH is the most common reason for a prostate to grow, but it’s not the only one. Prostate cancer can also cause the gland to enlarge. Since early signs of BPH and prostate cancer can look alike, it's essential to see a urologist for any new or ongoing urinary changes right away.
Why a Urology Evaluation Is Essential
If you notice changes in urination, sexual function, or both, don’t try to self-diagnose. A urologist can:
- Determine the exact cause of prostate enlargement
- Screen for early signs of heart disease if ED is present
- Recommend treatments that will best fit your priorities. For instance, the medication tadalafil is unique in that it is approved to treat both ED and urinary symptoms from BPH. For men who deal with both conditions, it can be a helpful option to discuss with a urologist.
You don’t have to live with interrupted sleep, urgency, or the frustration of ED. Addressing both issues can restore intimacy and protect your long-term urinary health.
