According to foreign media such as The Sun, medical staff at the University of Pittsburgh Medical Center in the United States succeeded in transplanting their garden stem cells to a 26-year-old man A who is atypical.
Jeongwon stem cells are adult stem cells in the testis of male testicles, which can be made into sperm through differentiation processes.
A became anapathetic due to chemotherapy he received to treat bone cancer when he was young.
Before cancer treatment, the medical team collected sperm stem cell tissue from A's body and stored it frozen.
Researchers at the University of Pittsburgh later transplanted cryopreserved stem cells back into A's testicles. Currently, it is known to maintain a normal state without side effects.
No sperm has been found in his semen so far, but the researchers said no testicular tissue damage was found due to the procedure.
The researchers plan to examine semen twice a year to determine whether sperm cells are produced.
Many medical experts have mixed reactions to the procedure.
Cedars-Sinai Medical Center urology Dr Justin Houman "If the safety of garden stem cell transplantation is demonstrated, it could be an innovative fertility recovery technology for men who have lost their ability to produce sperm.""Especially for cancer survivors who have been treated before puberty or men with genetic or acquired testicular failure."," he said. Another expert pointed out that "it is likely that the patient will not be able to restore full fertility because the amount of stem cells taken when he was young is small.'
Until now, only animal experiments such as mice and monkeys have been conducted on this transplant method, and it is the world's first clinical trial on humans.
Dr. Justin Houman, who led the study, added that `Although this fertility repair is a promising medical and science, it is still in its early stages, so many difficulties are expected.'
Meanwhile, studies have shown that anamnesia affects about 1% of men worldwide. About 10 to 15% of infertile men suffer from amygdosis, according to a survey. This condition is presumed to be caused by hormonal dysfunction, obstruction of the reproductive tract, or genetic disease.
