How Can Health Drink Make Penile Erection Permanent

Christopher Woods, a New York man has sued the maker of the health drink Boost Plus, saying the vitamin-enriched beverage gave him an erection that would not go away; reposts AP .
Woods said he bought the beverage, which is made by the Swiss-based Novartis pharmaceutical company, on June 5, 2004, and drank it.
He woke up the next morning "with an erection that would not subside" and sought treatment of the condition, called severe priapism, court papers say.
Woods, 29, underwent surgery for implantation of a Winter shunt, which moves blood from one area to another.
