But recently a team of scientists announced they had made artificial sperm from human bone marrow , and media reports abounded with the dire news that my goodfellas and by extension, me had been rendered unnecessary. There are at least half a dozen reasons why such speculation is silly, some scientific and some practical. For example, as long as sex feels good and remains no more expensive than dinner and a bottle of wine, most people will use natural-grown sperm. Still, suggests Gregory Stock, director of the program on medicine, society and technology at the UCLA School of Medicine and the CEO of a biotech company called Signum Biosciences, it is very interesting that there were any stories at all. Experiments have created eggs and sperm, so-called artificial gametes, from embryonic stem cells and other cell types for years now with limited success, so the bone marrow work does not represent a giant leap. And the stories are reminiscent of some that were printed 10 years ago when the birth of Dolly the sheep, the first mammal cloned from an adult cell, was announced.

We men were declared washed up then, too. Well, what does that say about marriage laws? About whether men are needed?

There are all sorts of ways that play into our psyche, who and what we are, what relationships are all about, the limits of the technological vision of ourselves.

I just want to know why you women are in such a rush to get rid of us. A world without our sperm So permit me to run with the tabloid visionaries and see where men wind up in a world that does not need our sperm because you ladies are out there making them on your own.

Video: Conceivable? Rates of women who are opting for preventive mastectomies, such as Angeline Jolie, have increased by an estimated 50 percent in recent years, experts say. But many doctors are puzzled because the operation doesn't carry a percent guarantee, it's major surgery -- and women have other options, from a once-a-day pill to careful monitoring.

In the near term, men may not be much different than the present. Well, strictly in terms of keeping the human species alive, you women need some of us. We make a glut of sperm, millions of them, so one man can spread a lot of seed. Sperm banking has long been an important part of in vitro fertilization, just as bull semen is integral to dairy production. Frankly, you only need a small tribe of us guys equipped with porn magazines and plastic cups. You could feed us, groom us and give us a little exercise — pretty much like you do now.

Baby-making by the numbers: Stats on women in the workplace, the rate of assisted reproduction, numbers of twins and triplets, and much more. Once a worldwide network of stem cell banks is established already starting, by the way , the raw material represented by the cells could be used to make any kind of cell in the body, including sperm. Catalogs could be produced the way listings of sperm donors are created now, outlining features and benefits.

Women could make a toll-free call. Stag colonies of men eating Doritos? Being a man, I will assume that most women would prefer to give birth to female babies, girls being far more competent, intelligent and with less propensity to crash motorcycles.

Two hundred years from now, a few isolated stag colonies are inhabited by men who have mutated to survive solely on Doritos. Other future technologies like synthetically created genomes, artificial chromosomes and manufactured cells also may be used as part of reproductive services.

And if any of this ever comes to pass, we are going to have to make conceptual adjustments because such developments will further change an already changing outlook on culture and on what it means to reproduce.

This is a real question for women, too. Roger Gosden, an IVF pioneer, favors the research. Show discussion.

Pregnancy in Bone Marrow Failure Disease

Log in Advanced Search. A study in mice suggests that bone marrow-derived stem cells may play a role in establishing pregnancy. The research showed that the stem cells can travel through blood circulation to the uterus, making it more receptive for a new embryo. Specifically, the authors showed that these cells concentrate in the lining of the uterus where the embryo is about to implant.

Bone marrow-derived cells play a role in changes to the mouse uterus before and during pregnancy, enabling implantation of the embryo and reducing pregnancy loss, according to research published September 12 in the open-access journal PLOS Biology. Although the study was done in mice, it raises the possibility that dysfunction of bone marrow-derived progenitor cells may contribute to implantation failure and pregnancy loss in women.

It may be hard to get and stay pregnant for some would-be mums, but there is hope. Scientists have discovered the vital role bone marrow plays in pregnancy, which can lead to new therapies in the future. In 10 seconds? Stem cells play a key role in successful pregnancies.

Bone Marrow Stem Cells May be Vital for Pregnancy

Since the late s, scientists have explored how to produce sperm where all of the chromosomes come from a female donor. Creating female sperm was first raised as a possibility in a patent filed in [3] by injecting a woman's cells into a man's testicles, though the patent focused mostly on injecting altered male cells into a man's testes to correct genetic diseases. In , Japanese scientists partially confirmed such techniques by creating chicken female sperm in a similar manner. It is therefore concluded that most of the W-bearing PGC could not differentiate into spermatozoa because of restricted spermatogenesis. One potential roadblock to injecting a woman's cells into a man's testicles is that the man's immune system might attack and destroy the woman's cells. In usual circumstances, when foreign cells such as cells or organs from other people, or infectious bacteria are put into a human body, its immune system will reject such cells or organs. However, a special property of a man's testicles is that they are immune-privileged , that is, a man's immune system will not attack foreign cells such as a woman's cells injected into the sperm-producing part of the testicles. Thus, a woman's cells will remain in the man's testicles long enough to be converted into sperm.

Bone marrow stem cells may be vital for pregnancy

By Roxanne Khamsi. In a first step towards creating artificial sperm cells, researchers have turned human bone marrow tissue into primitive sperm cells. If these precursor cells can be coaxed into becoming fully functioning sperm cells, the technique could allow infertile men to father their own children, and even allow women to produce their own sperm. But experts caution that provoking the sperm precursors to fully mature presents a serious challenge.

The breakthrough paves the way for lesbian couples to have children that are biologically their own.

Researchers found that when an egg is fertilised, stem cells leave the bone marrow and travel via the bloodstream to the uterus, where they help transform the uterine lining for implantation. If the lining fails to go through this essential transformation, the embryo cannot implant, and the body terminates the pregnancy. Study first author Dr.

Stem cells have generated such an enormous amount of interest, in part, because of their applications related to areas such as fertility and genetics. In that same light, their interest for solving reproductive challenges has also generated a great deal of controversy. This is particularly true in the application of stem cells to facilitate reproduction for gay couples. At present, there are a number of research laboratories that are focused on the creation of cells that are genetically male but have been produced from eggs. Alternately, they are also trying to create sperm from female eggs.

How bone marrow boosts chances of a healthy pregnancy

Monday, 16 April Maggie Fox Reuters. Scientists have created cells that look like immature sperm. But no-one knows if they will be able to mature and go on to fertilised eggs Image: Science. Stem cells taken from men's bone marrow can be coaxed into something that resembles an immature sperm cell, researchers working in Germany say. They hope to use their findings to come up with new and better fertility treatments for men and women. Nayernia, now at the UK's Newcastle University and the North East England Stem Cell Institute , had previously grown sperm cells from mouse bone marrow and used them to fertilise mouse eggs and create living baby mice. In the latest research, his team worked with men who were about to have bone marrow transplants, a common treatment for cancer. The researchers removed some of the bone marrow, a rich source of so-called adult stem cells, cells the body uses to replenish blood, bone, muscle and other tissues.

Jan 31, - British scientists are ready to turn female bone marrow into sperm, cutting Gay men could follow suit by using the technique to make eggs from male Couples who have children from artificial sperm created from women.

Bone marrow failure diseases frequently occur in women who are young and of child bearing age. People with these diseases have legitimate concerns about whether a pregnancy will cause their infants to suffer from the disease or its treatment, or whether their own disease will relapse. But the goal of modern therapy and modern obstetrics is to minimize both maternal and fetal complications. Experience from published reports suggests that in the past ten years, both maternal health and fetal outcomes have improved in women with aplastic anemia and PNH. However each bone marrow failure disease aplastic anemia, MDS, PNH has to be evaluated separately for pregnancy complications.

If the lining fails to go through this essential transformation, the embryo cannot implant, and the body terminates the pregnancy. But knowing that bone marrow has a significant role is a paradigm shift. In this study, the researchers were able to prove the physiological relevance of stem cells to pregnancy.

I guess after being told to "Go Fuck Yourself" for so many years, these scientists finally found a way to do it. There will be some interesting debates raging about this one for a long time.
