Sperm Stem Cells Were Used for the First Time in an Attempt to Restore Fertility


“What we expect from this initial transplant was to show that the method is safe and it is possible,” said Orwig. Ultrasounds show that the HSU’s testicular tissue procedure was harmless with the procedure and has a normal number of hormone levels. So far, its semen still has no sperm.

More transplant can occur soon. The Orwig team has been a bank testicular texture since 2011, and now some of these patients are reproductive. The group received permission from the institutional viewing board from the transplantation of stem cell transplants, as well as the transplantation of the testicular tissue transplantation clinical trial.

Transplanting the immature testicular texture is an alternative to the study of researchers. This technique is attached to the skin of a piece of the protected tissue scrotum. Hope, the tissue will grow and eventually produce sperm. In apeOrwig and his team transferred testic tissue, then eight and 12 months later, sperm was removed. The sperm fertilized eggs and eventually transferred embroiders from Women’s Macoues, which resulted in a living birth.

A sliding of tissue to get sperm is less invasive procedure than the skin, less invasive procedures than a stem cell transmission that requires the opening of the testicle.

When the Orwig team started collecting the testicular texture first, he first thought that they will beolate from the seed and then they will get more stem cells. They did this with the first few patients, including HSU. But later, many stem cells or more of the pieces of tissue were able to get many stem cells or more, then remove them from melting and cells. This could only pass the HSSU, because his cells were frozen. Other patients with all the tissue fragments will be the option to test either stem cell or tissue transplant.

In January, the researchers in Vrije Universityit Brussels and Brussels in Belgium, said they did the IVF The first testicle texture transplant In a patient who receives chemotherapy in childhood. The patient will be monitored for a year with testing for sperm for a year. After a year, doctors will produce some transplanted tissue pieces to check the sperm.

“For these patients receiving life-saving cancer treatment, they are often stayed with permanent impaired productivity,” Robert Brannigan, United States Reproductive Medicine and Urological Professor at Northwestern University. “It is difficult to say which approach will be more effective, but I think both intimacy really deserves to learn more.”

A similar procedure called an ovarian texture transplant is available for women’s cancer patients and resulted in more than 200 live births around the world. In adult men in the need for chemotherapy, there is a choice of equivalent practices in freezing eggs, because women can take two or three weeks in freezing eggs, and who can not come to the patients. If the egg ice cream is not possible, a piece of ovation can be collected for a piece of tissue and retained for subsequent use.

“It’s nice to see that we will take a little we can offer to our young women we can offer,” said Jonathan Routh, Duke says a child urologist in health. “The number one seemed to be alive, but I think this life is the number two and I think this study will affect the future.”

HSU understands that technology is still in the baby and it may not work for him. Although not having a biological child, these methods end hope that other childhood cancer patients will open. “It’s a new starting experience,” he says. “More support, no more research and the so much information, the better for people like me.”
