A Chinese research was done in which a stem cell was converted into primitive sperm and used to fertilize an egg. Healthy pups were produced. Thus the healthy off-spring produced was encouraging.
This study indicated that the pups were all healthy and grew to produce their own offspring.
The experts have expressed joy, saying that this would be of great help in human therapies.
It could assist the boys that have lost their fertility to health issues such as treatment of cancer, mumps infections that have made them unable to produce sperm.
The process by which sperm is made in the testes is long and complicated and it takes close to a month from the time it begins to when it ends.
The scientists are now in a position in which they can reproduce the feat in the laboratory.
The Chinese research team stated that their experiments are in line with international set standards that are supposed to be followed while reproducing meiosis in the laboratory.
Professor Badge Robin of UK-based Francis Crick Institute said that the research was an impressive work that ended up with exciting results that would turn out beneficial in basic research.
He added that the most people may have the opinion that making sperm is easy. However, the results clearly deny this assumption.
University of Sheffield professor, Allan Pacey, sperm making outside the body would be an exciting happening for the scientists to handle. It would depict a great advancement in science as well as help infertile men.
He also stated that despite the results being encouraging; much is yet to be done in applying the technique as a way in which human male infertility would be taken care of.
One of the challenges that face the process is how to get the starting material. There is no adult that has embryonic stem cell. The Chinese team believes that if the skin cell can be converted into the stem-cell state, the challenge will have been overcome.
