After prostate removal, the body undergoes significant changes in urinary and sexual function. Most men experience incontinence and lose the ability to ejaculate, while erectile function may return gradually depending on nerve preservation and rehabilitation.
Urinary changes and incontinence
Immediately after surgery, the most noticeable change is urinary incontinence. The prostate contributes to the internal urinary sphincter, and its removal means the body must rely entirely on the external sphincter and pelvic floor muscles to control urine flow. Without the prostate’s support, leakage is common, especially during physical activity.
A urinary catheter stays in place for one to three weeks to allow the surgical connection between the bladder and urethra to heal. Once removed, most men begin to regain control slowly. Many experience stress incontinence—leakage when coughing, sneezing, or standing—especially in the first few months.
Pelvic floor exercises, such as Kegels, are often recommended to strengthen the muscles that control urination. Most men see significant improvement within 3 to 12 months, though recovery time varies by age, overall health, and surgical approach.
Loss of ejaculation and fertility
The prostate and seminal vesicles produce most of the fluid in semen. After their removal, men no longer ejaculate fluid during orgasm. This is known as a dry orgasm. The sensation of orgasm may remain, but the physical release of semen stops permanently.
Because sperm can no longer travel through the reproductive tract and seminal fluid is absent, natural fertility ends. Men who wish to have biological children after surgery are advised to consider sperm banking before the procedure.
Sexual function and erectile recovery
Erectile function is often affected because the nerves responsible for erections run close to the prostate. Even with nerve-sparing techniques, these nerves can be stretched or temporarily damaged during surgery, leading to erectile dysfunction.
Recovery is gradual and may take up to two years. Doctors often recommend early use of medications like sildenafil (Viagra) or vacuum erection devices to promote blood flow and help preserve tissue health. The success of recovery depends on whether nerves were spared, the patient’s age, and overall health.
Anatomical changes during surgery
The prostate sits between the bladder and the urethra. Removing it requires the surgeon to disconnect the bladder from the urethra and then reconnect them directly. This new connection, called a urethrovesical anastomosis, must heal securely before normal urination can resume.
A small space is left where the prostate once was. Nearby organs shift slightly to fill the area, but the main functional impact comes from the loss of the prostate’s structural and sphincter roles. The pelvic floor muscles must adapt to provide more support for urinary control.
