Talk:Urethra

Removed from article

We are taught the urethra has 4 parts the pre-prostatic part being missed out herre so I will add it in.

I think the "make sure to clean the urethra toy" needs to be made NPOV; make it say something like "health professionals advise people to clean urethra toys", instead of reading like a sex ed brochure.

Wheres the fourth pre prostatic part of the uretha?

Why does someone keep deleting the fat that there are 4 parts of the male urethra?

Does the circumcised penis tip count as a diseasily transmissible surface?

Like what if you cuddle naked afterwards? Or have oral if you know you have no diseases?

Defensive Function of the Urethra

@Zefr:

I recently added information about the urethra's active defensive function based on research published in PNAS. My edit was reverted citing WP:MEDANIMAL and "uncertain significance," but I believe this was a misunderstanding for several reasons:

1. The article is titled "Urethra" not "Human urethra" - my edit didn't claim human medical relevance but provided general information about urethral function observed in research.

2. The paper I cited ("A 5-HT-mediated urethral defense against urinary tract infections") includes research on both mouse and human urethral tissue, confirming the presence of the same neuroendocrine cells and receptors in human tissue.

3. Regarding "uncertain significance": The research was published in PNAS, one of the most prestigious scientific journals with rigorous peer review. The paper specifically states in its "Significance" section that this finding is relevant to human health, particularly in understanding urinary tract infections, which "rank among the most prevalent human infections worldwide." The authors include multiple human tissue confirmations to establish relevance beyond animal models.

I propose reinstating a version of this information in the Anatomy/Function section:

"Research has identified that the urethra is not merely a passive conduit for urine but contains neuroendocrine cells that can detect and respond to pathogens. These cells release serotonin (5-HT) which may help defend against ascending urinary tract infections."

This statement doesn't make claims about human medical relevance while still providing important information about urethral physiology. The PNAS research supports this as a general biological function.

The PNAS report is clearly speculation (an "hypothesis") from early-stage lab research, far too preliminary and unconfirmed to use in the encyclopedia. Wait for a future WP:BMI review. Zefr (talk) 16:21, 23 April 2025 (UTC)
