Is it permissible to use or trade in penis enlargement products for those who suffer from a small size?

It is permissible for someone suffering from a pathological shortness of his penis to consult doctors for medicine or a device that enlarges the penis without surgery, provided that there is no harm and the treatment is free from prohibited methods. He may also masturbate with his wife's hand. It should be known that a small organ may not be a defect except by way of delusion, and this condition is called "Body Dysmorphic Disorder" (BDD). Many doctors believe that there is no harm in a small penis. It is also permissible to sell these medicines or devices if they are proven to be free of harm.
