New Technique May Protect The Female Egg During The Freezing Process A growing number of women are now having their first babies well into their thirties and even in their forties. There are several reasons for waiting to start a family. Women who wait usually have more financial security, more emotional maturity and more time to commit to their marriages and their careers before focusing their energy on children. Unfortunately, it's a biological reality that the female egg becomes less viable over time – unlike male sperm. The egg cell is also much harder to freeze because it contains a lot of water that can crystallize during the freezing process. Now, a company called ViaCell is testing a new technique that is designed to protect the egg during freezing. The multiple site clinical trial is expected to enroll approximately three hundred healthy women, age twenty-one to thirty-five, who are currently seeking fertility treatment to demonstrate births from previously frozen eggs. Currently, there is not an FDA approved product for egg freezing. The study is expected to be completed in 2009, and if the results are positive, it may give women more options when planning their families. Produced for ViaCell, Inc

Get IVF treatment in India by the best kind of doctors and medical staff and the surgery cost in India is really affordable to the pocket of all. IVF treatment or In vitro fertilisation is a process in which the female egg cells are fertilised by sperm outside the womb, in vitro also called petri dish. Get your IVF treatment in India wth the best kind of medical rehabilitation facilities. IVF treatment or in vitro fertilization is a major treatment in infertility when other methods of assisted reproductive technology have failed. The process involves hormonally controlling the ovulatory process, removing ova (eggs) from the woman's ovaries and letting sperm fertilise them in a fluid medium. The fertilised egg (zygote) is then transferred to the patient's uterus with the intent to establish a successful pregnancy. The first "test tube baby", Louise Brown, was born in 1978.

ICSI treatment in India by most qualified medical experts of Mumbai and Chennai with all medically modern healthcare facilities is being provided at a very less cost offered to International as well as Indian patients. Patients are being provided with the facilities JCI certified infertility surgeons of India having vast experience of performing numerous numbers of successful surgeries in all the major cities such as Delhi, Mumbai, Chennai and Bangalore. ICSI treatment in India also commonly known as IVF- (In-Vitro-Fertilisation) is saved for a few exceptions conducted according to hormonal stimulation of ovaries. The aim of the hormonal therapy is to let several follicles on both ovaries grow up and to extract several egg cells able to fertilisation. The phase known as "down-regulation" prepares the body for stimulation by suppressing bodily hormone production or excretion. This so-called "down-regulation" can be regulated either through oral medication or daily subcutaneous injections, the advantage being heightened external control. India is one of the best options for the abroad patient who desire to have child but with medically modern healthcare facilities in low cost options. The payment modes for the patients are also made easy as payments for the surgery could be made via credit cards, debit cards, wire transfers etc and foreign currency exchange counters in the hospital itself. Patients will also offered with a holiday vacation tour at various marvelous and beautiful tourist destinations of India arranged by the medical tourism in India at an affordable price offered to complete your medical tourism experience along the ICSI treatment in India in India.

(Image source: Wired) BY EMILY SPAIN You're watching multisource health/science news analysis from Newsy. Researchers might have a cure in the works for infertility in women. Scientists say they found ovary stem cells they can convert into unfertilized human eggs. WBAL has the details of the experiment. “Similar experiments in mice show transplanting the egg cells into the ovaries of infertile females produced healthy offspring. Scientists believe the same is possible in humans and are exploring the possibility of human stem cell banks.” Researchers from Massachusetts General Hospital used a cell-sorting machine to find reproductive cells from the ovaries of mice and then did the same with donated human ovaries. According to the New York Times, the experiment on human ovaries had positive results. “The egg cells, when injected into mice, generated follicles, the ovarian structure in which eggs are formed, as well as mature eggs, some of which had a single set of chromosomes, a signature of eggs and sperm.” The BBC talked to one doctor who called the results of the experiment "extremely significant" and "a potentially landmark piece of research.” The outlet quoted him saying: "If this research is confirmed it may overturn one of the great asymmetries of reproductive biology - that a woman's reproductive pool of gametes may be renewable, just like a man's." Other researchers aren’t so sure. Some question if egg-producing cells actually exist in ovaries. Director of the Center for Reproductive Sciences at the University of California plays devil’s advocate to the research. Discovery News has his thoughts: “I would like to see better characterization of this very small pool of cells that may be present in the ovary...’ [He] noted that some properties of the egg-producing cells described in this study do not match descriptions from previous studies.” According to The New York Times, doctors say cells grown in labs often develop abnormalities. And even if the research is confirmed, use of them in fertility treatments is still years away. Transcript by Newsy.

Read All Please; The human body is the most complicated machine in the world. We see with it, hear with it, breathe with it, walk and run with it, and sense pleasure with it. Its bones, muscles, arteries, veins and internal organs are organized with marvellous design, and when we examine this design in detail we find even more amazing facts. Every part of the body, though each may seem to be so different from another, is made up of the same material: cells. Cells, each of which is one thousandth of a millimetre, are the structural units that form our body and everything in it. Some of these cells unite to form bones, others to form nerves, the liver, the inner layer of the stomach, the skin or the cornea of the eyeball. Each has the size and shape that exactly meet the requirement of that part of the body. How and when did cells, which have such varied functions, come into being? The answer to this question will take us into a process whose every moment is filled with mystery. All the approximately 100 trillion cells that make up your body today came from the division of one single cell. That single cell which had the same structure as all the cells in your body now, came from the union of your mother's egg cell and your father's sperm cell. In the Qur'an, God sometimes refers to the wonders of the earth and the sky, and sometimes to the mysteries of the creation of living things as various signs of His existence. One of the most important of these signs is His wondrous creation of human beings. In many verses, as a lesson to human beings, God advises them to turn and look at their own creation. He explains in detail how human beings come to be and what stages they pass through. In Sura 56, He tells of human creation: We created you, so why do you not confirm the truth? Have you thought about the sperm that you ejaculate? Is it you who create it or are We the Creator? (Qur'an, 56: 57-59) The essence of a human being composed of 60-70 kilos of flesh and a mass of bones was originally contained in a drop of fluid. It is certainly a wonder that an intelligent, feeling human being with the faculties of speech and hearing and with a remarkably complex physical structure could come into existence from a drop of fluid. This development was certainly not the result of a random process or the operation of chance, but rather of a conscious process of Creation. This site will explain in detail a wonder that is experienced continually, by every person on the face of the earth the wonder of human creation. It must be made clear that what is dealt with in this site is only a part of the intricacies of human creation; but even what is related in this site reveals once again the eternal power of the Creator, His limitless knowledge and intelligence that surround and embrace the whole universe. And it will remind human beings that Almighty God is "the Best of Creators". We created man from the purest kind of clay; then made him a drop in a secure receptacle; then formed the drop into a clot and formed the clot into a lump and formed the lump into bones and clothed the bones in flesh; and then brought him into being as another creature. Blessed be God, the Best of Creators! (Qur'an, 23: 12-14) *******www.creationofman****

Double fertilization in flowering plants involves the fusion of two sperm cell nuclei of the male gametophyte with two cell nuclei of female gametophyte. One sperm fuses with the haploid egg cell to form the zygote; the other sperm unites with the diploid central cell to form a triploid cell that will develop to an endosperm.

Scientists from the University of Tübingen has succeeded in harvesting stem cells from the testes of adult men. In lab tests with mice, the cells behaved just as embryonic stem cells do, including the ability to develop into many different kinds of cells: bone, muscle or nerve. The possibilities are exciting for potentially curing such diseases as Parkinson's disease. You can't see it with the naked eye, but in this test tube, human tissue is being grown. Thomas Skutella and other German researchers are growing a blood vessel, adding stem cells in layers. It's fundamental research for creating tailor-made replacement tissue, which could one day help patients with diabetes or Parkinson's Disease. Prof. Thomas Skutella, Uni Tübingen: "We hope at some point to be able to regenerate or replace more complex organs like the liver or even an entire heart muscle." With the help of his team, Skutella has now come a step closer to realizing this dream. The scientists have derived so-called human adult germline stem cells, or GSCs, from the testes of adult males. Could they be the alternative to human embryonic stem cells? Searching for embryonic stem like all-rounders The embryonic stem cells are all-rounders. They can reproduce endlessly and turn into any kind of tissue: nerve, bone, muscle or blood. But generating them requires that the embryos be destroyed. So the research in Germany is strictly regulated. So-called adult stem cells are no problem, those derived from skin for example. But by their nature, they can't turn into other kinds of cells because they come from already developed tissue. Researchers are now working to make these adult stem cells become more than just their own type. For men only? The human adult germline stem cells discovered by the Tübingen researchers seem to represent a third type. They are all-rounders, just like embryonic stem cells, and they survive longer than adult stem cells do. But stem cells derived from testes - does this limit their potential application to men only? Prof. Thomas Skutella, Uni Tübingen: "Here we're talking about stem cells that later develop into sperm cells. Women have them too, stem cells which in their case develop into egg cells. We can in turn take those cells from adult women." The researchers are testing their new human adult germline stem cells on laboratory mice, examining to what extent they can turn into other cells. They inject the mice with the GSCs. The injected cells form a lump. And there the researchers find every kind of tissue. Skin, nerve, cartilage and bone cells. Prof. Thomas Skutella, Uni Tübingen: "We didn't do much manipulating. We added things to the cell culture within the limits allowed in clinical research. So we would be very close to the clinical testing stage for these cells."

An embryo is a multicellulardiploid eukaryote in its earliest stage of development, from the time of first cell division untilbirth, hatching, or germination. In humans, it is called an embryo until about eight weeks afterfertilization (i.e. ten weeks LMP), and from then it is instead called a fetus. The development of the embryo is called embryogenesis. In organisms that reproduce sexually, once a sperm fertilizes an egg cell, the result is a cell called the zygote that has half of the DNA of each of two parents. The resulting embryo derives 50 percent of its genetic makeup from each parent. In plants, animals, and some protists, the zygote will begin to divide by mitosis to produce a multicellular organism. The result of this process is an embryo.

Implanon is a long acting contraceptive implant that is fitted by trained healthcare professionals. The implant is 4cm by 2mm in size and is a semi rigid plastic rod containing the active substance etonogestrel (a progestogen). Implanon has now been replaced by Nexplanon (October 2010) Nexplanon differs from Implanon in two ways: • the applicator has been redesigned. • it is radio-opaque and can therefore be located on an X-ray if necessary. The Nexplanon / Implanon is inserted just under the skin of the non-dominant upper arm. This allows a small amount of etonogestrel to be released into the bloodstream continuously. This prevents the release of an egg cell from the ovaries and also makes it more difficult for sperm to enter the womb. When you use Nexplanon / Implanon you do not have to remember to take a pill every day. Therefore, Nexplanon / Implanon is very reliable. This video shows how the implant is inserted. It is effective for up to 3 years and can be removed at any time. There are many methods of contraception Implanon is just one. Discuss fully with your family doctor or nurse to ensure that you use the safest and most appropriate method. Builth and Llanwrtyd Medical Practice has made every effort to ensure that the information in these episodes is accurate, up to date, and as helpful as possible. However we will not be responsible for any inaccuracies or omissions. In particular if you are unwell, it is important that you do not rely on information from the Internet - you should seek professional medical advice from your Doctor. If your condition is getting worse, or if you are seriously ill, you should call or visit your Surgery.

The penis goes into the vagina very easily, although there are many stages so it goes in "right." When the penis goes into the vagina it may go in far enough that - if the female is a virgin - it may tear the small layer of tissue that partially covers the vaginal opening, known as the hymen. When the female is not a virgin, depending on the elasticity of the hymen, the penis should slide in without any difficulties. The vagina is actually the name of the canal in the woman's body, a natural orifice like the mouth or anus. During sexual intercourse, the male's penis is inserted into the vagina. If the penis even comes in close contact with the area near the opening of the vagina, whether the male ejaculates or not, it can result in pregnancy (the woman can conceive a baby). The ejaculated fluid is called semen, and contains the male sex cells, or sperm. If the sperm cells enter the vagina, they will attempt to fertilize an egg cell from the ovaries, which will become a fetus and eventually a baby. Note: To avoid injury or discomfort, be sure that the vagina is lubricated before intercourse. Normally body contact is sufficient to begin this process. If natural fluids do not provide a comfortable insertion, there are artificial lubricants Using a Condom: Condoms are usually lubricated, maybe not enough, but it helps a lot and they're smoother. This may make the process easier, thanks to the added lubrication. The most important thing is to first be sure that the female is receptive and has given permission for the penis to be inserted into her vagina. That is step number one! 1. Begin by ensuring the vagina is properly lubricated, either through oral or manual stimulation or a store bought lubricant. 2. Inserting the penis into a dry vagina may cause the female a painful and unpleasant experience. 3. Proceed slowly by using the head of the penis to feel for the opening of the vagina. Do not stab at it. Be gentle. 4. Place the head of the penis into the vagina and slowly lean in to finish the insertion of the penis. The penis is now inserted and sexual intercourse can proceed. The best way to approach this is to make sure the girl is adequately aroused. You do this through foreplay (sexual touching and caressing before intercourse.) You can also use vaginal lubricants Factors that may prevent insertion would include; the penis is not erect enough, the vagina is not wet enough or lubricated, the vaginal opening is too small for insertion When a man is sexually aroused, his penis becomes longer and stiffer. This is called an erection. Where a man's penis usually is soft and hangs downwards, when he has an erection it is hard and points forwards and slightly upwards. When a woman is sexually aroused, some lubricating fluids are produced by the Bartholin's glands which are located close to the opening of her vagina which can make it more slippery inside. So the combination of the man's and the woman's sexual arousal makes it very easy for the man to put his penis inside the woman's vagina or for the woman to take the man's penis into her vagina.

If you have more questions about eye color, check out these informative website: *******www.allaboutvision****/conditions/eye-color.htm Article on how Blue Eyed Parents can have Brown Eyed children *******genetics.thetech****/how-blue-eyed-parents-can-have-brown-eyed-children Calculate the Probability Your Child Will Have a Certain Eye Color *******genetics.thetech****/online-exhibits/what-color-eyes-will-your-children-have Wikipedia has a wealth of information on eye color, including anomalous (unusual) conditions in regards to eye color. *******en.wikipedia****/wiki/Eye_color Also below, I go into depth about how genes control eye color: ~~~~~~~~~~~~~~~~~~ Eye color is commonly taught as a trait controlled by one gene. However, eye color is a polygenic trait meaning it is controlled by multiple genes. These genes in combination may allow large amounts of melanin (a brown pigment) to be deposited or less melanin to be deposited. For example, a person who has genes that deposit larger quantities of melanin would have either black skin, black hair, and/or dark brown eyes. A person who has the genes that deposits smaller quantities of melanin would have white skin, blonde hair, and/or blue eyes. I don't talk about the genotypes associated with eye color in this video-- which would be quite complicated. Genotypes are the underlying genes associated with a trait. For example, cleft chin (or butt chin) genotype is cc, and not having cleft chin is CC or Cc. Why two letters? Because you receive one letter (or one allele) from each parent, one coming from dad's sperm cell and one coming from mom's egg cell. Depending on the trait, one allele might dominate over the other allele. For example, a person with even one "C" will have no cleft chin, but someone has to have 2 "c's" in order to have cleft chin. Having no cleft chin is the dominant trait (since it masks over the cleft chin allele) and having a cleft chin would be considered the recessive trait (since you need both alleles to express this trait). Now eye color is slightly complicated because there are said to be two genes associated. with eye color (thus, eye color being a polygenic trait). For example, BBGG genotype would be someone has only the genes for dark brown eyes, depositing the greatest amount of melanin, whereas bbgg would be blue eyes, depositing the least amount of melanin. But what about green eyes? The green eye genotype would have to be bbGg or bbGG. If a person had even one big "B" that person would have brown eyes. So brown eyes can be any of the following genotypes: BBGG, BBGg, BBgg, BbGG, BbGg, Bbgg. But those genotypes might have varying shades of brown-- think of each big letter depositing the greatest amount of melanin and every small letter depositing less melanin. What if two parents, one with dark eyes and one with light colored eyes had children? There's a whole host of possibilities that can rise from such a cross because it'd be difficult to determine the exact genotype of both parents, thus, it'd be difficult to determine the exact genotypes of the children. For example, lets say the dark eyed parent had a genotype of BbGG (one possible genotype of brown eyes), and the light eyed parent had a genotype of bbGg (one possibe genotype of green eyes). After conducting a dihybrid punnet square cross, you would find that the parents would have 25% likelihood of having kids with BbGG genotype (brown eyes), a 25% likelihood of having BbGg genotype (possibly lighter colored eyes), 25% likelihood of having bbGG (green eyes), 25% likelihood of having (bbGg possibly lighter green eyes). It's a complicated cross, but it shows how siblings can have varying shades of eye color depending on the genotypes of their parents. What you can be sure of is that at least some of the offspring will be carriers for light colored eyes ('b" or "g") and thus, have the possibility of having children with light colored eyes if the other parent carries similar genes. ------------------------------------- In this video, I explain how melanin plays a role in eye color. In addition, one can see a noticeable difference between two brown-eyed individuals, where the brown-eyed individual with a green-eyed and brown-eyed parent has noticeably different colored eyes compared to an individual with two brown-eyed parents. By the way, the person with the green-eyed and brown-eyed parent is my boyfriend, Jon. The person with the two brown-eyed filipino parents is me! And the dogs are my dogs, Chippy and Butters.
