Some factors leading to inflammation include too frequent or too infrequent ejaculation, sexual arousal without ejaculation, withdraw at the time of ejaculation, excessive alcohol or spicy foods, prolonged sitting or bike riding, etc. The
prostate may then become secondarily infected and require antibiotic therapy
for cure. Sometimes as the prostate gradually enlarges with age, friable veins called varices develop on its surface. These are also prone to tearing.
