I can't find any "evidence-based" reasearch - there is one which contains some interesting information: ncbi.nlm.nih.gov/pmc/articles/PMC5383635/… but actually it has zero value, because authors are concentrated more on cultural restrictions in mother diet. They does not criticize diets that are claimed to solve "allergies".

I agree that such name focuses on mechanics, but question is "what is also known about this mechanics?" (complaints, observable degenerative changes) - in other words is it a symptom or just a "name".

Some pop medicine articles talk about blood stagnation others about prostate secret stagnation. I would like to ask authors of ncbi.nlm.nih.gov/pmc/articles/PMC5040619 why you need those weakly defined terms? and why it is not enough to stay just with "ejaculation frequencies"? What I do not understand there? Symptom defined through statistics is common place now?

Thank you. I had seem this. Exactly after this I have decided to ask that question. Am I right that this confirms that "prostate stagnation" is not a clinical symptom description, but just some kind of mental construct?
