NEW YORK (Reuters Health) – Researchers have discovered a new medical breakthrough that gives hope to male infertility patients treated for cancer and found a way to freeze the testicles.
Powerful chemotherapy and radiation therapy can damage the undeveloped testis and about a third of men who have survived cancer are sterile at puberty.
But researchers have discovered the possibility of extracting testicular tissue at an early age and freezing it. It seems that the experience of the developed technology has been successful in the monkey and can be used soon in humans.
The experts said the study, published in the journal Science, was a "major step" in the development of treatments to restore fertility in men, who may become infertile.
In the monkey experiment, researchers from the University of Pittsburgh's School of Medicine extracted the testes from 5 small monkeys and froze living tissues. The animals were then subjected to chemotherapy.
When the monkeys approached puberty, tissue samples were dissolved and replanted in monkeys. The team found that after a few months, testicular tissue produced sperm used to generate embryos.
