Final answer:
Damage to the prostatic plexus due to prostatectomy or injury can cause complications like erectile dysfunction, as these nerves control arterial dilation necessary for an erection. Disorders like prostate cancer can also necessitate a prostatectomy, affecting sexual function and urinary control.
Step-by-step explanation:
A prostatectomy or injury to the prostatic plexus, which lies within the fascia of the prostate gland, can cause a number of complications due to its role in controlling erectile function. The prostatic plexus is a network of nerve fibers associated with the prostate gland and is integrally involved in the erectile process. Damage to these nerves during surgery, such as a prostatectomy, or as a result of traumatic injury, can lead to erectile dysfunction. This is because the nerves of the prostatic plexus are responsible for the arterial dilation necessary to achieve and maintain an erection. Additionally, disorders of the male reproductive system including prostate cancer can have related symptoms or may necessitate a prostatectomy. This procedure and any associated nerve damage can profoundly impact sexual function and urinary control.
