Erectile dysfunction occurred after benign prostatic hyperplasia.

Benign prostatic hyperplasia was diagnosed three years ago. I have been casually treating it, but upon reflection, I think I also developed erectile dysfunction at some point. Is erectile dysfunction inevitably associated with benign prostatic hyperplasia? In my case, I also experienced a stroke about ten years ago, so I wonder whether my erectile dysfunction is caused by the stroke or by the benign prostatic hyperplasia. It's ambiguous. However, when I had the stroke, my erectile dysfunction was not as severe as it is now. It seems more likely to be related to benign prostatic hyperplasia, but the exact diagnosis is uncertain. I would like to hear medical opinions on this. I also want advice from someone with experience.
