A couple of questions...
1) Is it reversible without a problem? (I heard it costs a lot and not as much effective as the original operation)
2) Do you feel only steril as a man or.. err..ahem.. don't get me wrong, no offense, no concealed thought, half?
I'm just trying to understand the psychological side of the thing.
It can be reversible, but one shouldn't consider this if they have any notion that they might want to reverse it. It does not always work.
For me it doesn't make me feel one bit less of a man.
Let's clear a few things up. The sperm factories (the scientific name is blocked) are not harmed at all. There are tubes called vas deferens that carry sperm from the factory to the seminal vesicle which is on the bladder and connected to the prostate gland. This is where sperm is combined with the rest of the seminal fluid. Sperm make up only a very small amount of the seminal fluid. Those vas deferens tubes are cut. So, sperm is still produced it just doesn't have a path to the urethra anymore. The seminal vesicle still produces seminal fluid. The normal variation in the quantity of seminal fluid is far greater than any reduction in quantity caused by the absence of sperm. The sperm-less fluid is indistinguishable from before as far as you can tell without a microscope. The feeling of release, for me at least, is exactly the same. Any difference caused by having a vasectomy, if there is any, is much less significant than the normal variation from one time to the next.
Like I said in my thread about this, if I had been abducted by aliens and been given a vasectomy while unconscious (and provided ample recovery time) I would have absolutely no reason to think anything had changed. I simply would not know that it had been done because all things related to sexual activity would work and feel and seem the same.
If the option you had been using to prevent unwanted pregnancy was female hormonal birth control then you'd be in for a nice surprise I think. Hormonal birth control has many side effects, such as weight gain, loss of libido and decreased enjoyment. So once you get the surgery your female partner will probably start losing weight (fairly dramatically in my case), want to have sex more often and enjoy it a lot more when she does. So all the changes I have encountered are positive.
Psychologically I don't need sperm in my seminal fluid to feel good about myself. I never had any desire to go around planting my seed in foreign fields. I'm not sure why else I would be disappointed to no longer have to worry about causing unwanted pregnancy.
The analogy I like is this:
If someone was going to shoot you with a gun, but gave you the option to wear a bullet proof vest or take the bullets out of the gun, which option would you choose?
