As everyone knows, Viagra is used (and sometimes abused) as a treatment for impotency. It works by expanding blood vessels. Apparently, a prematurely born baby was on the verge of death and, in connection with heart surgery, some enterprising doctor prescribed Viagra—opening the child’s lung blood vessels, allowing better oxygen absoroption, and saving his life. It was experimental, but it worked. It will be interesting to see if this opens a whole new use for the drugs currently used to help sexual dysfunction in men.
