The spermatic duct valve


The spermatic duct valve is an invention of a Berlin master carpenter.
This is a valve that is supposed to regulate the admixture of sperm with the man's ejaculate.

To do this, it is implanted in the vas deferens and can be switched on and off with a button on the testicle.
This means that the vas deferens do not have to be severed as with the vasectomy contraceptive method.

It should not have any negative effects on the body and guarantee lifelong sterility.

Why should you do that?

The spermatic duct valve is intended to represent a new alternative to the previously possible methods of contraception for men: condoms and vasectomy.
Since, unlike the vasectomy, the sterility of the man is to be preserved, the inventor advertises on his website with the name “The revolution in contraception”.
The valve can be switched on and off with a button under the skin on the testicle.
So you can stop the contraception at any time.
Since this method of contraception is hormone-free, it should not have any side effects that would otherwise occur as a result of hormone preparations.

Only one person in the world wears this implant and that is the inventor himself.
So until now there have been no medical studies on this new method of contraception.
The website is looking for test subjects for a study.

In view of these facts about the spermatic duct valve, one cannot answer this question as it stands today.

How does that go?

First of all, the patient should undergo a preliminary medical examination.
The urologist then examines the patient for any anomalies and answers any open questions.

The operation itself takes place under local anesthesia and takes about 30 minutes.
The vas deferens are cut through and then reconnected by the implant.
Then the vas deferens are brought back into the scrotum.
The inner skin layer is closed with absorbable thread material, the outer skin layer with a medical adhesive.

If the valve is closed after implantation, it is believed that sperm will remain in the ejaculate for up to three months.
That is why it is advisable to have a urologist take a semen analysis.
This is the only way to be sure that you are sterile.

Is that painful?

The intervention to install the valve takes place under local anesthesia.
Therefore, the patient does not feel anything during the operation.
However, as with any other operation, tissue is broken open and sewn back together again, so that pain should be expected later.

What does the spermatic valve cost?

The implantation of the two spermatic duct valves should cost around 5,000 euros.
Added to this are the costs of a semen analysis after three months. These are around 100 euros.

What are the risks and long-term side effects of the spermatic duct valve?

Nothing is currently known about risks or long-term side effects.Because worldwide only the inventor carries the valve.
The manufacturer equates the risk spectrum with that of a vasectomy and classifies it as very low.

Can you reverse that?

The manufacturer does not currently provide any information on this.

Is the spermatic duct valve safe as a contraceptive method?

How safe the spermatic duct valve really is cannot be said at present.
There are no studies on this.
About three months after the operation, you should have a urologist take a spermogram to see if there are any sperm in the ejaculate.

Who can implant a spermatic duct valve?

The implantation of the spermatic duct valve is carried out by specially trained urologists.
