Penis shrinkage due to zero testosterone

[tinypenis (imported)]

I'm very curious to know how much penis shrinkage occurs with zero (or near zero) testosterone levels. Of course, with that level of testosterone, nocturnal erections no longer occur. Considering that nocturnal erections keep a man rock hard for hours every night, their absence has got to have a major effect on penis size over time.

So, if you have experience in this area, or if you have good anecdotal evidence, can you answer some or all of these questions?

1.) how much does the penis shrink with zero testosterone?

2.) how fast does it shrink?

3.) how much does the girth decrease?

4.) does it eventually stop shrinking, or does it just keep getting smaller and smaller?

5.) are there any other changes, like foreskin regrowth, penis retreating into the body, scrotum shrinkage, etc.?

As a 14 year no T eunuch the penis does shrink. Once shrunk it does not shrink anymore. Well it does when you are out in the cold walking your dog. Sadly to the point it barely sticks out of both your underwear and your jeans. Difficult to piss behind a tree and with the dog pulling at the same time. But I digress.

I would say I lost about 40% of length and 25% of girth. My scrotum has also retracted close to my body. My penis has not retreated into my body but I have noticed that with obese older men it can retreat. Knowledge from my patient care days regarding older men's penises.

Even on hot summer days I still look like I jumped into ice cold water. A visual to help you understand how things look.

after my castration my penis shrunk about 25% but my empty scrotum is still hanging down and is the same size but it's only been about 6 months since i lost my testicles

I am only one of quite a few folks here who have extensive education and work experience in clinical medicine and medical research settings and who have undergraduate and graduate degrees in one or another form of biology.

That having been said, my decision, in 1986, to get my bilateral orchiectomy was motivated by my noting a number of relatives who died comparatively young (including during their fourth decade of life), and recognizing my most likely having the particular genetic condition which "caused" such cancer. 25 years later, it has become incontrovertible that I have a form of the genome for familial adenomatous polyposis (FAP); and the medical information I had in 1986 strongly suggested to me that testosterone was a contributing factor, in my particular family, to the development of terminal cancer.

The State of California includes testosterone on its list of known carcinogens. However, FAP does not develop because of carcinogens alone; the FAP gene produces a tumor suppressor protein which, in the presence of a tumor cell, apparently activates apoptosis to prevent cancer development.

While the common view as I have found it in the medical literature is that FAP is of dominant inheritance, I find it to be a recessive gene at a fragile locus, such that inheriting a non-functional tumor protein gene from one parent does not result in failure of tumor suppression until the functional allele in a cell mutates somatically into a non-functional form, such that, in a cell having two non-functional tumor suppressor protein genes, tumor suppresson (apoptosis) will cease.

Because tumor cells form frequently, everyone would plausibly die in utero from cancer absent effective apoptosis resulting from functionally effective tumor suppresor genes.

Apoptosis? Programmed cell death. Apoptosis is why people are not usually born with webbed fingers and toes. In ducks, apoptosis not working in feet results in ducks having webbed feet. Programmed cell death, with different programming, is why ducks ordinarily have webbed feet and people do not. Ducks do not usually have a functional apoptosis program for the inter-toe web; people usually do.

Or, to use the classic Eunuch Archive phrase, "your mileage may vary."

After 25 years as a "no testosterone" eunuch, it is my observation (I am rather good at making biological measurements) that I have not experienced any penis shrinkage as a result of testosterone avoidance.

Unlike many folks, or so it seems to me, my being autistic may have given me an advantage in expecting the results of my orchiectomy to be mostly what I could not otherwise expect; in expecting to find results which I was unable to expect, I was never disappointed. I expected shrinkage. Had I wanted that, surely I would be very disappointed by now.

However, I seem to have an inner way of living which is, as I experience it, profoundly and gently affirming of my life and life experiences. I anticipate being unable to accurately anticipate the details of very nearly every event in my life, and my way of adapting to life experiences is, consequently, awfully simple.

Something happens (i.e., some life event which I have not accurately anticipated) and I adapt to it (or learn from it) as I am able to adapt (or learn), and the way I am able to adapt and learn is always, in my life experience, both necessary and sufficient; and whether I adapt to an event by remaining alive or by becoming dead (adapting by becoming truly dead seems to not have really happened yet); and if I remain alive, I will experience more events to which my adaptation and learning will always, in my view, be both necessary and sufficient.

Thus, I have never learned to actually hate any aspect of my life or any aspect of any aspect of life.

Had avoiding testosterone for more than 25 years resulted in my penis shrinking, I would have adapted to that. Observing that my penis did not notably shrink resulted in my adapting to that.

However, my adaptation to life events has never become passive. I actively work away at the effort I make to adapt to my life experiences, doing so with all the effort I can muster, doing so unrelentingly.

Did my scrotum shrink? Not that I can tell. Do I want it removed? No, because I avoid surgery whenever possible because I can see no benefit to me commensurate with the very small risk a "scrotectomy" would convey.

Not autistic? The way I adapt to life experiences may not be appropriate for you. But that is not for me to say for sure, not one way nor another.

I have to agree with tugon, but it's taken a few years to shrink that much. It's juvenile or pre-puberty looking to me.

I have been a eunuch now for 6.5 years, have lost my scrotum (after 3 years of eunuchism). My penis has shrunk about 45 percent maybe a little less when I don't have an erection (which is hard to come by). I read somewhere that part of the shrinkage is due to little or no erections. Don't know if that is right and can't remember where I read it. All I know is my "equipment" did shrink. Not so much in girth as in length.

[littletits (imported)]

My penis shrinkage has neen dramatic to say the least. I had a fairly average penis prior to castration. It is now less than half the length it was. I can never get erect due to damage to the organ in the incident that resulted in me becomong a Eunuch and I have little sensation in it. My scotum is also very small and does not hang down betwen my legs but remains close to my body and when cold it looks as though it is no longer there. The shrinkage had all occurred in the first year to a year and a half. I have not noticed it shrinking further since. My scrotum and pubic bone suffered damage at the time and this may have caused the shrinkage to be more pronounced.

[hkeunuch (imported)]

I have been a chemical eunuch for a few years now. The penis, which was never big to start with, shrank noticeably. It started as a cut cock, and now under normal circumstances, it has a full foreskin covering the entire glans. It took me a few years to reach this state. Girth did shrink some, but not nearly as noticeable.

Now that I have been off Androcur for a couple of years already, it remains as small as before. It did not seem to get much smaller.

I have always been into stuffing my genitals into my body. Now sitting down, penis needs no help to retreat into the body. But I guess I don't have sufficient fat around to keep it in all the time.

Scrotum does not really shrink much per se. But because the testes shrank a lot (to about 1/3 of their original size, clearly smaller than the bunched up vas deferens), there is no longer enough weight or volume to keep the scrotal sac stretched / hang down any more. But the skin is still there, but it does seem to generally bunch up nearer to the body.

Penis shrinkage due to low testosterone is a medically proven phenomenon. I've seen some papers saying that you lose 20% of the smooth muscle. I couldn't find that, but a quick search turned up the following showing that a number of things occur to change structure and function of the penis:

http://www.doctorpg.org/health-testosterone-gel.html

There is a large body of scientific evidence which shows that androgens are important for maintaining the function and structure of penile nerves, blood vessels, muscle, connective tissue matrix, and the tunica albuginea.

Androgens are known to act on nerves which control erectile function. Studies on castrated animals have shown deterioration of cavernosal and dorsal nerves which was reversed by testosterone replacement restoring erectile capacity.

Low levels of androgens are also known to damage the lining of blood vessels in the penis inhibiting their ability to produce nitric oxide (NO) which is a substance which plays an important role in producing erections. The erectile dysfunction drug Viagra works by increasing NO levels.

Similar studies have also shown that androgens maintain penile smooth muscle content. Loss of smooth muscle due to androgen deprivation caused lower intracavernosal pressure, in other words lower blood pressure inside the penis and weaker softer erections. Similar changes to penile muscle have been seen in humans suffering from erectile dysfunction with the severity of their symptoms correlating with the degree of muscle loss. Worryingly the smooth muscle in the corpora cavernosa (the vascular inner part of the penis that fills with blood during erection) seems to be replaced by connective tissue which leads to fibrosis. This would prevent the normal expansion of the penis during erection leading to a diminished erect penis size.

A similar process occurs in the tunica albuginea which is an elastic outer layer surrounding the corpora cavernosa. This layer is normally rich in elastic fibres which allow it to expand easily when the inner corpora cavernosa blows up like a balloon as it becomes engorged with blood during erection. However in castrated animals the elastic fibres have been seen to be replaced with inelastic collagen. So again the penis is unable to expand normally.

I believe most, if not all, transsexuals use chemical castration drugs for months or years before transgender surgery. Use of these chemical castration drugs, shrink their penises. If you look at Dr. McGinn's website, you'll easily see that in some of the pre-op pictures, that most of the penises shrank dramatically before surgery. Some in the transsexual community will state that this shrinkage is not beneficial because it doesn't give the surgeon much to work with, but others will tell you that penile skin, which is used to line the new vagina, stretches enough so that it's not usually much of a problem. Scroll down and take a looksy: http://www.drchristinemcginn.com/servic ... plasty.php

Some of the penises look normal and some have obviously shrank.

[smoothie36 (imported)]

I measured my penis before and after both chemical and surgical castration, and determined a total loss in length of about 1/3.

[harveywrwh (imported)]

After reading all of the above with interest. I would like to add my results. After almost a year using Depo Provera. I have found that my penis has shunk alot. The Results of the chemical castration I do like. I have found that using Depo once a month is best for me. The shrinkage is great. I did not measure my penis before I started. Which was about 6 inches hard. now not hard at all., and about 1 1/2 long.. I do like the sexaul Calm that goes with castration. But there is one item that does go along with this. It is the shortness of breath and low energy. Hopfully that will go away. At first when I started I wanted surgal castration. But I started reading alot on this website, I found that there was alot of great info on this subject. So I went the chemical route, and I do like the results. I did do the two injections at first and then two weeks later with another, That dropped am testrone down below 40. After three months. I found that was to much for me. So I backed off the injections of Depo. So then I went to once a month of 150 Mg. Now my testrostone is around 90 to 100. I like the results better. At this point I do not know if I will have the surigal part done. At this point it will be a look and see. and do a lot more reading on the subject. This website is GREAT. I do want to thank the folks that have added this info

Interesting Thread. Mee too. Low testosterone = small , smaller, smallest penis. It retracts into scrotum which makes me look like I don't even have a penis.

This is a result of testicles destroyed by alcohol injections. But it doesn't matter. Depo or alcohol, dead is dead.

Now that I have crossed over into the "netherland" of dead testes and virtually no testosterone, i can honestly say,

while erections and ejaculations were fun, due to the tremendous negative impact that testosterone had on my mind, body, and emotions,

I do not miss testosterone at all.

For anyone who have the benefit of a normal testosterone life, they can not possibly understand my point of view,

I envy their ability to live a "normal" life.

But we are what we are.

Easy for "normal" people to condemn or be critical of anyone who is not "normal".

They are more to be pitied than censured.

It was good to read your post tinypenis. I can provide you with my experience. I am on 5mg of Finesteride for BPH. I decided to reduce my T down to castration levels. I have used Androcur and Depo Provera. The combination really did a number on my penis. It was never that big to begin with. In 8 months I have lost over an inch of my penis. It used to be a bit above 5 inches and today I have a hard time getting to 4 inches. The girth also is reduced but my testicles have taken the biggest hit. They are less than half of what they were before. I wonder when the shrinkage will stop. My penis has started to retract into my body. At times it looks like I am uncut. It is amazing. As I continue my journey, I'll keep you posted.

Tigon, I was castrated 5 years ago, and my cock has now shrunk @ least 25% !

I never wake up with a "woody" either !

JaneKane?....Is there a corelation with apoptosis and the degeneration of cells due to the natural loss of telomere's or as I call it random allele data on the ends of the chromatids?

Cell division isn'ta perfect process. Each time the enzyme telomerase acts during the final stages of mitosis the process strips the ends of the chromatid each and every time. sorta live shaving it off. The danger being if we expend these protective caps from our DNA sequence.

How is Testosterone related to this process?

Further more Isn't estrogen related to this aswell?

Because my understanding is that both hormones will cause cancer

Also worth noting that different people have longer telomere sequences than others.

I read a paper a while back that centenarians who have a long history of no cancer tend to have longer telomere protective cap sequences in there dna?

It would be nice to hear feed back from you. I quit university by the time I finished organic chemistry, instead devouting my pursuit with engineering. But I always had my hunches about this dillema.

NB = In a perfect world, we live to chase our wildest dreams. However in an imperfect world the best we can do is to strive to reach whats possible

Im no expert in the field of biology, heck I got a C when I finished organic chemistry.

Truth is it was getting me no where. I had to change my career plans

I have been on an HRT regimen for about 6 months now..It consists of 5MG of finasteride daily for BPH, and two 25 mg doses of Spiro daily(50 mg total)....plus 2 doses of 2 mg estrofem daily..(4 mg total)..My penis has shrunken about 1/3, I'd say...with the forementioned reappearance of a foreskin(due, I'm guessing to loss of mass, and the skin, being about the same size, simply sliding forward). My testes have also shrunk...They don't hang like they used to..They present a smaller and much tighter appearance..

Both lovely side effects...The one thing I dislike however, as mentioned, is the shortness of breath..Does this ever go away? Or lessen? Thanks Jackie

I have had no supplemental T since my castration about 3 years ago. The last time my doctor checked, my T was less than 10 or unmeasurable.

My penis was about 7 1/2 inches erect, but is now the size of a prepubescent male. When it is cold out, my penis sometimes turns turtle and is hard to find. I have to sit to urinate to keep from making a mess.

My scrotum has shrunk until you can see a single fold in the middle that is less then 1 inche long when you get out of a hot shower.

Most of the time my scrotum pulls tightly against my groin.

I have not had an erection or ejactulation since about 10 weeks post castration. It went away so slowly/smoothly that I did not even realize it was gone until well afterwards.

For some time now I have been going to the Southwest Milwaukee YMCA, 3 times a week for exercise. I go in the morning when the place is flooded with Senior Citizens. Trust me, these men all walk around the lock room, shower area, heated whirlpool and Sauna stark naked. And I have determined after two years of watching, Ain't none of them hung. These Senior Citizens with low amounts of T all have Tiny penis. And 90% of the are circumcized and 100% of them all have tiny penis.

I've gone from 5+ to 4+, but part of that may be age. Plus my erections now are springy feeling, not hard. Much more loose skin on the shaft as a result.

[stephaniesteve1 (imported)]

My penis has shrunk about 25 % in both length and girth. Erections are softer but still good enough to perform in bed .No morning erections and when flacid it is just such a nice small cock, seems about 50% smaller when flacid.

Whats not to like about that .

[OneBallBoi (imported)]

In my first post I made comment as to the size of my penis. It is so very small. It really ranks in the area of tiny now. Erect, if I could get an erection it might be 3 inches. Erection, what is that. I forgot it has been so long. Most of the time it is a mere one inch long.

[Jorge2008 (imported)]

How much time did it take for that shrinkage to occur? I'm asking this because I'm on Triptoreline now for 2.5 months and have almost no erections. But I'd like my cock size to remain what it is, for the occasion that I'd ever stop chemical castration.

Mine shrank by a little over 1/3 over a couple of years of no T the shrinkage between 6 months and a year were the fastest,
