Scientists create live offspring without a female egg.

A study documented in journal of Natures Communication has shown how scientists have been able to breed produce offspring's from 2 males.The experiment by the University of Bath rewrites years of biology teaching and could pave the way for a baby to be born from the DNA of two men. It was always thought that only a female egg could spark the changes in a sperm required to make a baby, because an egg forms from a special kind of cell division in which just half the number of chromosomes are carried over.Sperm cells form in the same way, so that when a sperm and egg meet they form a full genetic quota, with half our DNA coming from our mother and half from our father. Scientists have shown embryos could be created from cells which carry all their chromosomes which means that, in theory, any cell in the human body could be fertilized by a sperm.Three generations of mice have already been created using the technique and are fit and healthy and now researchers are planning to test out the theory using skin cells. The experiment involved, scientists stimulating an egg into developing into an embryo using special chemicals which makes the egg think it has been fertilized. Technically the cells in an embryo copy themselves completely when they divide, and so mirror closely most other cells in the body, such as skin cells. When scientists injected the embryos with sperm, they grew into healthy mice which went on to produce their own litters. The technique shows a possibility for gay men to have children, whose DNA was half of each of the couple, although a woman would still need to act as a surrogate to carry the baby.It also amplifies the possibility that a man could even fertilize his own cells to produce offspring containing a mixture of genes inherited from him and his parents. Women can also benefit from this technique, women whose fertility has been erased by cancer drugs or radiotherapy to have their own children. The current method is for eggs to be frozen before cancer therapy and later fertilized in an IVF clinic, but nothing can be done once the eggs have been lost may be due to aging . This technique will also help women to continue having children later in life even after menopause. Its known that women are born with all their eggs but these degrade with age, which makes conception more difficult in later life. The possibility of fertilizing new skin cells to produce off springs will improve and increase the chances of having a baby at any age depending on the health status of the mother. The animal world will also have a piece of the cake as conception using sperm cells with non-egg cells(primed skin cells) will prolong the lines of certain species as endangered species will not be a problem since the need to recover eggs is erased. The preservation of certain breeds,with pure lines will be possible and with immense benefits.
