new Treatment to eliminate male infertility



American researchers have found how to cultivate human stem cells to help children who have been treated for cancer and who have been infertile later in their lives. Healthy sperm cells have been developed before undergoing chemotherapy and are preserved in the study of mice.

For years, researchers have been trying to find ways to grow and expand these cells from testicular biopsies donated by young patients before treating cancer. But so far, there has not been a consistently successful approach.

Dr Sandra Riom, professor of cancer biology at the Pearlman School of Medicine at the University of Pennsylvania, and head of the oncology program at the Cancer Center in Abramson, said about one in 530 men aged between 20 and 39 years who survived cancer in their childhood, according to the association American cancer.. But cancer treatment, including chemotherapy and radiation, causes the children to suffer from infertility due to the killing of sperm stem cells. ”

Dr Gilles Gensberg, professor of Oncology and director of the Cancer program at the Children’s Hospital in Philadelphia, explained, “We never had any choice to save the fertility of pre-teen children, as these results are a first step for younger patients.”

The researchers found that testicular blanket cells are an important vital group for the maintenance and expansion of human cells in the laboratory. They also identified 5 growth factors produced by testicular endothelial cells to keep cells alive for a long time, and researchers even believe that they can be frozen until they are needed.
