Hello,
The results are within the normal limit. The causes for erectile dysfunction are many like diabetes, depression, autonomic nervous system problem, excessive alcohol ingestion or tobacco smoking etc. You may need to consult your doctor to see which amongst these causes are responsible for your problem. Once diagnosis is confirmed treatment can be planned.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
