“What we expected in this initial replacement was to prove that the method was safe and it was possible,” said Orvig. ” Ultrasound shows that the HSU’s testicular tissue was damaged by the tissue method and its hormone layers are in a normal range. Now, his semen is still lacking sperm.
More transplants can happen soon. The Orwig team has been banking testicular tissue from children for 25 years and now some of these patients are entering the breeding age. Its group received permission from the board of an institutional review for replacement of stem cells, as well as part of the testicular tissue, as part of it Clinical trialThe
An alternative method of replacing immature testicular tissues is an alternative method that researchers are exploring. In that technique, a piece of stored tissue is tucked under the skin of the scrotum. The hope is that the tissue will mature and will finally produce sperm. In MonkeyOrwig and his team replaced the testicular tissue, then removed the grafted tissue after eight to 12 months and removed the sperm from it. They used sperm to fertilize the eggs, and as a result the fetuses transfer the fetus from the female macak to the sarogette, causing birth to live.
To restore sperm, a sliver of tissues is cut off from the skin – it is a less aggressive method than a stem cell transplant, which requires opening the tests.
When the Arwig team started collecting the first testicular tissue, he thought they first separated from the tissue and then frozen more stem cells. They did it with their first few patients with HSU. But they later discovered that they discovered the whole tissue of the whole tissue whole pie May pass through the transplant, because only its cells were frosty. Other patients who frost the whole piece of tissue will have the option of trying to replace stem cells or tissues.
In January, researchers at the University of Vriz in Belgium Brussel and Brussels IVF announced that they played First testicular tissue transplant Patients who had chemotherapy in childhood. The patient will be monitored for one year, his semen will be tested for the presence of sperm. One year later, physicians will remove some replacement pieces of tissue to test the sperm.
“In the case of these patients who get life-saving cancer therapy, they often go to permanently with disabilities,” Robert Branunigan, president-elected of the American Society for Breeding Medicine and Professor of Urology at North Western University. “It is hard to say which method is going to be more effective, but I think both approaches are truly suitable for further study”
A similar method, known as ovarian tissue replacement, is available for female cancer patients and has been born more than 200 live worldwide. It is more advanced to the testicular frost and replacement because adults usually have the option of frozen sperm in need of chemotherapy, while on the other hand equivalent practice in women – freezing eggs – can take two to three weeks and patients may not have time to cross it before starting chemotherapy. When the egg is not possible, a tissue can be collected from the ovary and stored for use later.
Jonathan Routh, a pediatric urologist at Duke Health, said, “It was nice to see that we could give our youth the same opportunities that we were able to offer our young women,” said Jonathan Roth, a pediatric urologist at Duke Health. “Save the children is always the number one goal, but their lives allow to survive then and I think this study will really affect the future.”
HSU realizes that the technology is still in childhood and it may not be effective for it. Even if he may not have a biological child, he hopes that these techniques will eventually open options for patients with other childhood cancer. “It’s a practice that barely begins,” he said. “The more support, the more research and the more we have data we have, the more people like me get down the line”
