What Is Artificial Semen?

There are two basic types of artificial semen, as of summer 2011. The first type is used for decorative or demonstrative purposes. Typically, people use this kind of fake semen during some sort of demonstration that, were it a real event, would involve real seminal fluid. The second type is more of a scientific step forward. If successful beyond initial testing, this type of artificial semen might provide human health benefits.

Semen is produced in the testes, which are contained in the scrotum.

For years, artificial semen has been any kind of substance, crudely crafted or professionally manufactured, designed to mimic the appearance of real seminal fluid. Sometimes, this kind of fake semen is used in sex education classes. Teachers can pair the fake seminal fluid with condom demonstrators that have an ejaculation function.

Of course, this demonstration does not have to take place in a classroom setting. It can take place between two new sex partners, a parent and a child, or in any couple or group setting involving someone who is unfamiliar with and needs to learn how condoms work. Facilitators of sexual health seminars, retreats, and other group workshops might use condom demonstrators with ejaculation functions that emit artificial semen.

Similarly, sex industry professionals can use artificial semen when real seminal fluid is not possible or practical. Such instances might be during still photo shoots or even filming sessions. Depending on the company’s budget, this might be purchased from a manufacturer or made from the industry's own recipe. Typically, though, the sex industry uses a chemical compound called methyl cellulose for its artificial semen needs. Methyl cellulose is nontoxic and non-allergenic and these, along with other characteristics such as lubricating properties, could be why it is used in other sex-related products like personal lubricants.

The term “artificial semen” can also refer to real sperm created in an artificial way. Technically, this is an incorrect use of the term as semen and sperm are not the same. Semen is the fluid that holds sperm. Scientists who specialize in fertility issues have created germ cells that produce sperm. Experiments have shown that once these germ cells are inserted into the testicles of male mice, the mice can produce sperm that looks healthy and normal. Likewise, when the artificial sperm is inserted into the eggs of female mice, the female mice are able to conceive and deliver healthy pups, or baby mice. If and when such a procedure is fully regulated and made available to humans, it could act as a groundbreaking fertility treatment to help men and women who weren’t otherwise able to conceive children.

@miriam98: People have different tastes and sexual desires/ fantasies and want to be visually satisfied, if they can't have it for real. Just don't watch it. There something called freedom. Everybody has the right to do what he pleases without hurting each other in any way. This isn't hurting anyone.


Why do you think that everybody should figure it out for themselves? This is not the way how you educate young adults/kids to have responsible sex. What if they don't know, because they didn't care enough to inform themselves and you have a grandchild?

This is certainly not just about contraception; it is about STDs etc. They have to see something informative in school or else, but they won't get informed by porn. This is just fantasy and has nothing to do with real sex. They don't show how to handle a condom properly without making it useless. This has to be shown, not found out the hard way eventually.

Many young kids still have not heard about safe sex or know how to make responsible decisions.


@Miriam 98: Yes, you would probably have to see a triple xxx movie to see this happen. They call this the money shot when the guy ejaculates outside of the woman's body. But, don't despair. Many women are turned off by seeing this. You're not alone. But, some are also turned on by this and have incorporated this into their lovemaking for sexual protection against pregnancy and as a turn on for him and for her.

Just remember that the penis can be leaking seminal fluid all the time it is in a sexually aroused state so by no means is this a good solution for birth control. Wish more girls would realize this. It is not a safe sex act. You can still get pregnant. Use the pill, a condom or just abstain. Anything else could have you carrying a baby from someone you might not love, bringing a child into the world that you don't want, or contracting a sexual disease you certainly don't want.


@SkyWhisperer - Maybe most people don’t need an explanation but some of them might. Frankly, I think we should be prepared to offer all the help we can and not assume anything. The alternative to not properly using a condom is pregnancy or possibly even disease.

The real application here from what I can gather is how it can be used to generate real semen. It’s worked in mice so far so maybe it will work in adults.

Perhaps some males with fertility problems might benefit from it. I am not that interested in the demonstrative purposes of the stuff, but for medical purposes, we should continue researching.


@miriam98 - Yeah, the whole thing is bizarre to me too. What I find especially shocking is that the stuff is used in sex education classes. I need to check up on what my kid is learning these days!

I think it’s easy enough to explain the concept of a condom and what it does without needing a condom device and artificial semen. Kids are quite informed already, with most of them getting their real sex education from the movies and real life.

I can only imagine what such a class would be like, with kids snickering and giggling at the demonstration. I am personally not persuaded that anyone needs to figure out how a condom works. Just give them one and they’ll put two and two together. It’s not rocket science.


Well I must not be too familiar with the sex industry profession, I admit. I have absolutely no idea why they would need artificial semen for photo shoots or filming sessions. Do they actually show this stuff on film?

I have never seen an R rated movie that went this far; perhaps this is XXX fare. Personally, even if I were into those movies, this level of gratuity would gross me out. Some things we don’t need to see, like people going to the bathroom in movies. The less that is shown the better.

Subtlety has always been the hallmark of good filmmaking in my opinion, but again, perhaps this is just a whole new genre that I am not familiar with.
