What is the function of injection?

Patient's question:

Patient Gender: Male
Patient Age: 25
During the examination, Alprostadil Injection was used. What should I do if the test results are lower than normal data?
Previous Treatment History and Effect: No treatment has been administered.

Doctor's answer:

Local alprostadil injection is used to diagnose erectile dysfunction. If it is only premature ejaculation, check for phimosis. If it is caused by phimosis, surgery can be considered. If it is due to excessive sensitivity, attention can be paid to techniques. Short-term use of sildenafil citrate or topical anesthetic drugs to reduce sensitivity can be considered. I believe everyone knows that prostatitis can cause significant harm to patients, so it is important to seek treatment as soon as possible. In daily life, pay attention to dietary issues and avoid stimulating foods. Maintain a balanced diet. Additionally, regular follow-up visits can be scheduled when necessary.
