In a paper forthcoming in the November issue of the journal Theriogenology, a team of researchers from the University of North Carolina at Charlotte and the Smithsonian Conservation Biology Institute, announced the first successful drying and rehydration of domestic cat spermatozoa using a rapid microwave dehydration method.

Far from being an esoteric accomplishment, the successful preservation of cat spermatozoa by dehydration is a potentially important step in addressing key issues involved in the reproductive biology of wild felids.

There is a significant risk that in the near future, species key to the biological diversity of the planet may either go extinct or be so reduced in their genetic diversity that wild populations are not viable.

Science might be able to rapidly and successfully improve the status of small animal populations if more "libraries" of preserved eggs and sperm are available.

Scientists could simply use stocks of reproductive material, preserved in stable, dried form, re-hydrate them and create a population of viable embryos.

The idea of preserving sperm, eggs and embryos for later use is not new, but generally the preferred preservation technique is for these materials to be frozen.

Around Empire Animalia, pregnant state is often for the fertilization of your ovum using a spermatozoon, a progression of your foetus while in the uterus and also its particular transport within the following community for a neonate.Biologically, women of all ages could be the exclusively gender selection perfect for remaining impregnated.

A great deal is carried out while in the health community so that you can escape all of our all-natural love-making properties : by way of love-making transplants, release of various growth hormones within homosexuals, etcetera.

Except in cases where, not surprisingly, there are actually experiments so that you can establish often.

Nonetheless less than ordinary scenarios, its exclusively around humankind this never remaining perfect for pregnant state is undoubtedly an dilemma.

However pregnant state is definitely taboo resulting from guidelines plus societal training some locations, it is far from hence and perhaps invited around some, primarily around Parts of asia.

Your Asian relatives results in being affected if pregnant state would not appear after the specified period.There are actually mental health problems that have an affect on married folks this could not generate pregnant state materialize.

Antoni van Leeuwenhoek, the person considered to be the world's first microbiologist, was born on this day in 1632.

Throughout his career he sent more than 560 letters to the Royal Society and is credited with a vast number of discoveries, from the sperm cell to a rare disease that involves incessant hiccuping.

Van Leeuwenhoek, whose microscope could magnify the users' vision by nearly 300 times, has been honoured with a Google Doodle on the 384th anniversary of his birth.

His lenses were characterised by silver or copper frames with an optical zoom of 275 times normal vision.

The biggest microscope was about 5cm long and was held very close to the researchers eye while facing into the sun.

Despite numerous attempts, it wasn't until 1957 that someone was able to recreate his method.

Most birth control, including condoms, targets the swimming portion of the baby-making biathlon; scientists haven’t been able to pull the plug on the sperm drilling operation itself.

To make their way from the cervix, through the uterus, and into a fallopian tube, sperm cells beat their tails side to side like a snake cutting across the countryside.

But that tail waggle is totally useless for pushing through an egg’s thick protective layer, called the zona pellucida.

The head of a human sperm is just five puny microns long.

Instead of beating side to side, it starts to turn in only one direction, corkscrewing the head forward, through the dense, viscous environment of the egg’s outer layers.

(Ion transfer across membranes is how cells generate the electricity they need to power motor function.)

p For the final stretch of their fertilization journey, sperm rev up their whip-like tails to ludicrous egg-boring speed.

But amid chemicals from old herbal remedies, sperm may be left feebly treading water a few strokes from the finish line.

Normally, progesterone, a hormone involved in pregnancy that is secreted by cells surrounding eggs, activates this ion channel during sperms’ final approach, the researchers report.

Because the herbal chemicals—called pristimerin and lupeol—are already used in traditional remedies (though not necessarily for anti-fertility purposes), the researchers are hopeful that they’ll easily pass safety tests and offer an effective alternative form of contraception.

For now, though, the chemicals are just in early lab testing—years away from marketable products even if tests in primates and clinical trials go well.

Lead researcher Polina Lishko, an assistant professor of molecular and cell biology at Berkeley, and her colleagues came up with the two chemicals after working out the mechanics of sperms’ tails.

p Astronaut reproduction could be possible one day, boffins reckon

Japanese scientists say reproducing in space could be possible one day, after preserved mouse spermatozoa kept on the International Space Station resulted in healthy offspring.

“If humans ever start to live permanently in space, assisted reproductive technology using preserved spermatozoa will be important for producing offspring,” the researchers wrote in a paper published on Monday in the Proceedings of the National Academy of Sciences of the US.

Radiation is more than 100 times more powerful on the ISS than on Earth, damaging DNA in cells.

Microgravity is less of a problem.

Previous studies involving other animals such as sea urchins, fish, amphibians and birds have concluded that it doesn’t hamper reproduction.

“Do sperm squirm the same in space?” Forget birds and bees.

NASA’s California Ames Research Center wants to know if human sperm measures up to bull sperm in space and Elon Musk’s SpaceX is helping.

On April 2, 2018, NASA launched freeze-dried samples of human and bull sperm on SpaceX CRS-14, the transport company’s fourteenth cargo resupply mission.

The giant rocket blasted off from Cape Canaveral for the approximately 41-hour flight to the International Space Station (ISS).

You can watch the bull and human sperm being launched in the SpaceX video below – no need for concern about the video rating, despite the transport company’s name.

NASA plans to compare male reproductive material from the two mammals to see how human sperm measures up to bull matter – additional fodder for a catchy project name.

It comprises of the organization of day by day infusions which cause the ovaries, rather than delivering a solitary ovum which is their main thing normally every month, to create more oocytes with the goal that a bigger number of incipient organisms can be gotten.Oocyte recovery comes straightaway.

When we have proof through the ultrasound examines that the follicles have achieved a satisfactory size, and we think about that there are a reasonable number of oocytes, we plan egg recovery (known as follicular cut) 36 hours in the wake of managing an infusion of the hormone hCG which makes the oocytes develop along these lines to the manner in which they would in a characteristic cycle.

This procedure can be performed through customary IVF, which includes putting an oocyte encompassed by spermatozoa on a culture plate, or else by means of ICSI, which comprises of embeddings a live spermatozoon into the oocyte by puncturing the last with the guide of a pipette.

The methodology is done in a working theater, in spite of the fact that it isn't important to utilize any sedation since it is a speedy and easy technique.

Anyway it's a smart thought to help yourself to remember IVI's record of accomplishment in the field: 9 out of 10 couples that counsel IVI because of issues with fruitlessness and put their trust in us accomplish their objective of getting to be guardians.

Medical experts have condemned the US government for its plans to lift a ban on some controversial biomedical research, raising fears that it could lead to part-human, part-animal embryo development.

Sounding like something from a budget sci-fi flick, the new policy would allow for Frankenstein-style experiments that take human stem cells to create hybrid embryos with those of animals, known as chimeras.

The government's National Institutes of Health NIH discussed reasons behind the proposed lift via a blog post by its Associate Director for Science Policy, Carrie Wolinetz.

In the post, Wolinetz outlined a new policy to permit scientists to get federal money to develop chimeras, under certain carefully monitored conditions.

But the news has worried some medical experts, who believe the research is unethical, and could spiral out of control; that 'playing God' with biology could one day lead to "adverse consequences", such as the creation of animals with partly human brains, perhaps giving them some semblance of human consciousness or human thinking abilities.

Another concern is that the cells could develop into animals with human sperm and eggs and breed, producing human embryos or foetuses inside animals or other hybrid creatures.
