Stem cells are ‘grasp’ cells that may become different kinds of cells within the physique.
In a latest research, ten males with erectile dysfunction (ED), who had not responded to the utmost doses of Viagra and related medication, had a single injection of their very own stem cells into their penile tissue.

The pattern, taken from the highest of the hip, was processed to extract the stem cells which had been then handled within the laboratory to encourage them to multiply, after which injected into the penile tissue — once more beneath native anaesthetic in a day process.
The males had ultrasound pictures taken of the encompassing blood vessels earlier than and after the process. After six months, all of the sufferers confirmed improved blood move to the penis and 40 per cent had been in a position to have intercourse unaided and an additional 20 per cent in a position to have intercourse after taking Viagra.
One concept is that the stem cells multiplied over the six months and repaired broken blood, nerve or muscle cells which will have brought on the impotence.
The docs, from Benha University, Egypt, who led the pilot research, stated additional trials are actually wanted to verify the mechanisms concerned.
Commenting on the analysis, Professor Raj Persad, a guide urologist at Bristol Urology, careworn the research is small.
