Is that moral since God intended his creations to make sperm with their testicles or equivalent structures? I don't see why not. God ? And do we believe these scientists who will claim anything to get on the frontpage of a internet site. Time will tell I guess. And would it be possible one day for a woman to grow her own sperm? Now that would be immoral. They could do away with us Please Register or Log in to view the hidden image!
First, you have to actually believe that God exists to ask that question. I don't, so let them have at it. It might allow infertile men or men with low sperm counts to actually be a dad, or... It will leave men obsolete and women will be on the planet here all by themselves with no one else but themselves to blabber incessantly to. And w/o men, they'll have to find something else to compete for and act catty over.
Some egomaniac will substitute his sperm for everyone elses and everyone will end up marrying their siblings.
If it is ever put into practice it should be restricted to couples that can't have kids themselves. So the bone marrow stem cells of the father are taken and 'converted' to sperm cells.
boar semen Boar Sperm Introduction Boars are a kind of mammal. That means that they have fur, mammary glands and give life-birth, although some freak mammals lay eggs. Because they live in australia and there are many freaks there. Boars live in many places, but preferably in the forest. Male boars have testicles which are little factories hanging outside the body in a sack (nut sack in colloquial english) that produce sperm. Later some stuff is added to the sperm turning it into semen. This semen is ejaculated from the penis usually into a vagina for the purpose of fertilizing eggs. Needless to say it is important to fertilize eggs for the future of boarkind and hence the study of boar semen is incredibly important in this respect. Methods Boar semen was collected and frozen in a special substance consisting of ostrich egg yolk lipoprotein fractions. Ostriches are birds and not mammals, although they cannot fly. It was then injected into female boars, which are called cows. No... sows! results The frozen boar semen in the ostrich milkshake like supplement was succefully injected into sows and ...tada...they got pregnant from it. discussion It is very good that boar semen can be frozen because wild boars are very important for the maintenance of the forest and they also taste good. There were some slight problems with variation. Not all fertilization went so well. It is not sure if that is because the sows were missing out on the foreplay of the boars, the researchers had cold hands, or the ostrich milkshake was not optimal as a supplement. Further studies are needed. References Fraser L, Strzezek R, Strzezek J. (2007) Fertilizing capacity of boar semen frozen in an extender supplemented with ostrich egg yolk lipoprotein. Pol J Vet Sci. 10(3):131-5. Questions Is it ethical to interfer with the natural matings of the boar in his forest? Was the idea to use ostrich supplements a reasonable idea? How is the boar doing in your country? And should science concentrate on human research instead of messing with animals? And maybe you have still more ideas on this interesting topic regarding boar semen, based on a peer-reviewed article.
threat to sperm counters all over the world Automated Sperm cunting In our modern society we lose track more and more of the common man who needs a job to provide for his wife and children. Not even the noble field of science or the even more moral field of medical industry is nowadays escaping from the trap of automation. My eye fell on an article that will be the kick of death to many sperm counters world wide. A research group is automating the sperm counting, which is normally a very laborious process- read: it provides for jobs for Americans and other races (According to James R American is a race - complain to him. I don't want another infraction for posting reality). And their preliminary study shows that it works quite decently: Carrell DT, Emery BR. Use of automated imaging and analysis technology for the detection of aneuploidy in human sperm. Fertil Steril. 2007 Oct 11; [Epub ahead of print] Should we do something about it? And do these researchers have no shame?
Generally, if I have to have any contact with semen, it's the human variety that I prefer. That said, however, I was merely asking why there was such an interest. It's a fascinating topic, and your little prose there was certainly compelling. I was just wondering. That's all.
I was wondering, instead of collecting the semen and inseminating, why don't they just capture the males and move them around to different areas, stirring up the gene pool that way?
