There are many reasons for retrograde ejaculation after prostate surgery, such as urethral stenosis, surgical influence, higher blood sugar, etc. It is recommended to eliminate the disease through medication and surgical treatment. 1. Urethral stenosis: If the surgery causes damage to the membrane part of the urethra, it is easy to cause urethral stenosis and relaxation of the bladder neck. As a result, during ejaculation, semen cannot enter the urethra and instead backs up into the bladder. Urethral dilatation can be considered to treat urethral stricture and eliminate retrograde ejaculation symptoms. 2. Surgical effects: prostate surgery will inevitably have an impact on the body while treating the primary condition. If there is damage to the urethral sphincter, it may cause sphincter closure dysfunction, which in turn produces the phenomenon of retrograde ejaculation. It is recommended to follow the doctor’s advice and use drugs such as brompheniramine, neostigmine and midodrine hydrochloride for treatment. 3. High blood sugar: When the blood sugar in the body is high, it will increase the viscosity of semen, leading to the inability to ejaculate and the problem of retrograde ejaculation. Usually, you should use drugs to reduce blood sugar under the guidance of doctors, such as glibenclamide, metformin and so on. Secondly, you should also actively control sugar in your life and avoid eating sweets such as chocolate. To summarize, retrograde ejaculation after prostate surgery, the first thing to do is to identify the cause of the disease, and then you can target treatment. So after finding the symptoms, you should seek medical treatment as soon as possible and do not delay the condition.
