Patient's question:
Recently, I've noticed it's very difficult for me to ejaculate. I used to have no problems during sex with my girlfriend, but is it because we have sex too frequently? What should I do about this? Hello, what are the causes of erectile dysfunction?Doctor's answer:
1. Congenital factors Congenital wide bladder neck, congenital urethral valves or urethral diverticula, congenital spina bifida. These congenital diseases lead to incomplete bladder neck closure and increased resistance at the membranous urethra, causing retrograde ejaculation.2. iatrogenic factors Mainly include various bladder neck and prostate surgeries, thoracolumbar sympathetic nerve resection, retroperitoneal radical lymph node dissection, and other pelvic surgeries, resulting in nerve root resection or damage, leading to incomplete bladder neck closure and recurrent retrograde ejaculation.
3. Mechanical factors Traumatic and inflammatory urethral strictures due to increased urethral resistance obstruct semen during ejaculation.
