How to deal with impotence caused by chronic prostatitis?

Patient's question:

Medical history and treatment outcomes: Two interventional thermocoagulation procedures, three, microwave
Auxiliary examinations: Staphylococcus epidermidis identified in bacterial culture, normal white blood cell count
Detailed medical condition and consultation purpose: I have suffered from prostatitis for 8 years, and despite various treatments, it remains unresolved. Currently, a routine prostatic fluid examination shows normal white blood cell count. However, I still experience symptoms, primarily persistent testicular pain. The doctor ruled out epididymitis and varicocele, noting that the pain sometimes radiates to the perineum and lower back. The most severe issue is erectile dysfunction, as I rarely achieve erection with my girlfriend and have no morning erections or ejaculation. I have a history of long-term use of aphrodisiacs.

Doctor's answer:

Hello: I am not sure about the specific inspection fees, but based on your condition, it appears that you still have certain symptoms of prostatitis. Therefore, what you need to do first is to actively treat your prostatitis.
Many men cannot determine whether they have erectile dysfunction (ED), but in fact, one can judge the nature of ED by observing nocturnal penile tumescence (NPT). Normal men of all ages can experience reflexive penile erections during sleep. During adolescence, the average number of nightly erections is about 6, each lasting 20-30 minutes. In young adulthood, the average is about 4 nightly erections. Even in healthy elderly individuals over 65, there can still be a total of 1-1.5 hours of erections per night. Even children often experience penile erections during sleep.
Clearly, nocturnal penile reflexive erections are unrelated to sexual stimulation and are not influenced by psychological factors. Therefore, they can be used to differentiate whether ED is caused by psychological factors or by underlying medical conditions. If an ED patient has no nocturnal erections or if the degree of erection is below the normal range for their age group, it may indicate a medical cause, requiring further investigation. On the other hand, if an ED patient has normal nocturnal erections, it is unlikely to be due to a medical condition but rather psychological factors.
There are several methods for self-assessing nocturnal penile erections:
(1) Stamp Test: Place four around the penis, stick the overlapping sections together to form a ring, and then go to sleep. In the morning, check whether the stamp perforations are torn. If they are torn, it indicates nocturnal erections. If the overlapping sections come apart due to poor adhesion, it is not meaningful.
(2) Penile Circumference Measurement: There is a commercially available device with...
