How Does The Urethra Grow

How Does The Urethra Grow

Hi all,

I understand through jelqing and stretching you can grow your soft tissue, but how do the inner workings of the penis grow. To my best understanding, your soft tissue grows because it is like a sponge absorbing more blood with each exercise allowing it to become larger. How does this theory apply to the urethra or the vas deferens?

Thanks in advance

Not a clue, I’d imagine it stretches alongside the inner tissue. Akin to how you can stretch your skin? I’m just spit balling though

Any senior members have any info on this?

I did some reading, and the only way I can make heads or tails of it is to hypothesizes that maybe the urethra doesn’t “grow” or “extend”. from what I’ve read so far: “The mean urethral length was 22.3 cm with a standard deviation of 2.4 cm.” [PMID: 18778496] The smallest urethra they studied was 15cm and the longest being 29cm.

“Male urethral length was obtained in 109 men. After study permission was obtained, the subject’s penis was placed on a gentle stretch and the catheter was marked at the tip of the penis. The catheter was then removed and the distance from the mark to the beginning of the re-inflated balloon was measured. Alternatively, urethral length was measured at the time of cystoscopy, on removal of the cystoscope. Data on age, weight, and height was obtained in patients when possible”

Painful.

Anyway, to get back on track, I hypothesize that the urethra may not grow at all, rather, it just gets pulled more internally as the penis grows? As in, the urethra in it’s natural state may just have it’s “slack reduced” as the CS and tunica continue to lengthen.

I’m probably completely wrong, I’d actually like someone else’s 2 cents on this too.

Ouch, so if that being the case are we actually tearing at our urethra’s through PE?

Like I said, I’m only guessing, but from pictures and what I’ve read from the anatomy of the organ that’s the only way I can really picture it getting longer. The cells are “pseudostratified columnar and stratified columnar epithelia, [and] stratified squamous cells” which are different from the endothelial cells that line the CS. Whether that means they don’t really take to elongation and stretching that same way, I don’t know. Just trying to make heads and tails of it. Might go for a cytoscopy now and again in a year to let you guys know haha

This is something that Marinera posted in a science thread, might be of some use to you :P

Constrictive Penile Band Injury
Color Doppler Sonographic Assessment

trangulation of the penis is a rare injury, usually seen as a consequence of the placement of penile rings or bands, which are used to increase potency and to prolong erection.

Complications related to the use of penile rings or bands have been little reported. We report a case that describes the color Doppler sonographic findings in penile strangulation. The value of color Doppler sonography (CDS) in the clinical management of this injury is worth noting.

Case Report

A 36-year-old man was admitted to our hospital with a 3-day history of painful swelling of the penis related to a penile band, which had accidentally remained placed on his penis for 6 hours.

On physical examination, large swelling of the penis was evident. The dorsal artery pulse could not be palpated, although penile coloration was preserved. Color Doppler sonography was performed with a multifrequency linear array transducer (6–12 MHz, PowerVision 6000; Toshiba Medical Systems, Tokyo, Japan) to evaluate penile vascularization. Gray scale examination showed slight heterogeneity of the corpora cavernosa and spongiosum and poor definition of their margins. Moreover, a thick layer of echogenic tissue surrounding the Buck fascia was evident. In fact, the largest diameter of the penis was 7.3 cm, whereas the corpora cavernosa and spongiosum (considered together) measured 2.6 cm in diameter.

A color Doppler study revealed enhancement of normal vascularization (Fig. 1⇓) consisting of a circlet of arterial and venous vessels (due to enlargement of circumflex vessels). The dorsal artery was patent, maintaining its usual location (Fig. 2⇓). The superficial dorsal vein was laterally and dorsally displaced, being enlarged and patent (Fig. 3⇓). Intracavernosal arteries were also patent (Fig. 4⇓). Thus, the color Doppler study showed preserved vascularization, allowing us to adopt conservative treatment of the patient by following the wait-and-see rule. His penis recovered its normal size in 2 weeks without consequences.

The use of penile constrictive devices is a very dangerous practice that may produce a wide range of injuries from penile swelling to urethral lesions with fistulization and even gangrene.1 The fact that these devices produce ischemia has been shown by Broderick et al,2 who studied the value of CDS in the assessment of the hemodynamics of vacuum-induced erections. They concluded that because of the risk of ischemia, the constriction bands should not be worn for more than 30 minutes.2

………….
The clinical evaluation of penile strangulation includes assessment of temperature, color, sensation, the ability to void, and pulsation distal to the strangulation. The sonographic assessment should include careful evaluation of the corpora cavernosa and spongiosum, taking into consideration that the latter and the urethra are more susceptible to injury, because they are covered by a thin layer of fibrous tissue.1 Rupture of the cavernous bodies is very often associated with rupture of the urethra. Sonography should also exclude rupture of the tunica albuginea.

The color Doppler study provides information about vascular patency, and both arterial and venous vessels must be interrogated to rule out several important complications such as thrombosis or rupture of the cavernosal arteries and thrombosis of the dorsal penile vessels. Arterial supply to the penis is provided mainly through the dorsal arteries running close to the deep dorsal vein. Venous drainage of the penis is multiple. The superficial dorsal vein runs in the subcutaneous tissue, draining the prepuce and the skin of the penis, and joins the saphenous vein. The deep dorsal vein lies beneath the Buck fascia and receives the blood from the glans penis.3

…………….
Several cases of penile strangulation have been described in the literature,1,3–,5 although they have mainly focused on clinical management and surgical treatment. We have not found reports on the color Doppler sonographic assessment of such an injury, despite the fact that the value of CDS in the vascular assessment of the penis is widely known.6,7

In our case, CDS was able to show the patency of the vascular system of the penis. Both arterial and venous vessels were enlarged. This finding was thought to be related to reactive hyperemia (due to anoxic injury). The duration of this phenomenon is proportional to the duration of the occlusion.

The enlargement of the penile transverse diameter was caused by subcutaneous edema without changes in the size of the corpora. This fact could be related to venous stasis and also to impairment of lymphatic drainage.7 Supporting the latter hypothesis is a reported case of long-term use of a penis-enlarging ring in which pathologic examination revealed enlargement of the lymphatic vessels.8 Moreover, the residual edema may be considerable and in some cases may require removal of the skin and subsequent grafting.3

Wow thanks for all the research! And thanks to Marinera for posting that in the first place. But my question is then, how is PE possible if the inner workings of the penis don’t grow in the same way. Just very slowly and hopefully without injury? I’m not doubting PE works, only wanting to better understand the science/avoid injury.

Science of PE Posts and Threads. Link Here!

There’s a lot of theory in this thread, mainly to do with collagen, the CS, ligaments and tunica elongation. some with comparison to other body parts.
