Does A Vasectomy Affect Male Hormone Levels

No. Although common thought is that getting a vasectomy will lower testosterone levels, it will not. The purpose of a vasectomy is to stop the ability of the man to get the woman pregnant. Opposite from what many men think, it will not lower sex drive, cause erectile dysfunction or kill a man’s libido. On the other hand, without the worry of getting a woman pregnant, getting a vasectomy can increase sexual libido.


According to many men who have been asked about their vasectomies, they stated that getting the vasectomy gave them more freedom to enjoy sexual relations knowing that procreation was not an option.

With the pressure and worry of possibly creating a baby gone, a man (and a woman) can enjoy safe sexual practices in a more carefree way.

Can vasectomy affect testosterone levels? A vasectomy does not affect testosterone levels. It does not inhibit the ability to get or maintain an erection, it does not cause erectile dysfunction and it does not lower or diminish sex drive.

How Does A Vasectomy Affect Male Hormones?

A vasectomy does not affect male hormones. It does not lower testosterone levels at all. Studies show that when a man stops his ability to impregnate a woman by getting a vasectomy, the sperm that would naturally try to find the woman’s egg now will dissolve. After the sperm dissolves, it will be absorbed by the body naturally.

Sperm will still be formed in the male body after a vasectomy. Sperm is created within the seminiferous tubules located in the testes. When a man gets a vasectomy, the vas deferens is separated from each testis. This keeps the sperm from being able to be ejaculated; however, the testes will still work the same. Hormone production will not be affected.

Can a vasectomy lower testosterone levels? No. This is now clear. Hormone levels and sexual desire and functioning will not change despite getting a vasectomy. Men do not have to worry that this process will make him less manly, less sexually charged or not able to perform well.

What Happens To Your Sperm And Hormones After A Vasectomy?

When a man gets a vasectomy, it consists of clamping down on, cutting or sealing in some way the vas deferens that comes from each testicle. The testicles will not stop functioning and will still produce the same amount of sperm, but what is produced will end up being reabsorbed by the body.

The man will still ejaculate, releasing sperm which is contained in his semen. Semen consists of only two to five percent sperm and the rest of the ejaculate is made up of other bodily fluids. After a vasectomy, a man will never notice that the volume of ejaculatory fluid is less than it was before his procedure.

How Does A Vasectomy Affect Testosterone Levels?

Can a vasectomy lower testosterone levels? No. After this procedure, hormone levels including hormones like growth hormone and testosterone will not change. A vasectomy has nothing to do with the amount of testosterone that is being produced in the body. The pituitary gland is what signals the testes to produce testosterone and this gland is not changed by sealing the vas deferens. The testicles will still work the same.

It is a locker room joke that a man who has had a vasectomy will be any less of man. Will a vasectomy affect hormone levels? No. Will a vasectomy affect testosterone levels? No. This means that a man will still grow hair on his chest, he will still be able to have erections, he will still be able to ejaculate, he will get sexually excited and the vasectomy will not be the cause of erectile dysfunction. The only difference a man will experience is that his sperm will not be able to reach a female’s egg during intercourse.
