[|Human|] I have noticed a hard, almost vein like area under the gland of my penis.  I believe it has been there for a while.  It is white, and if I stretch the skin it seems that the hardest part is almost round.  I can pinch it between my fingers and feel that it is a very hard, possible ball shaped.  It seems that the white vein looking thing that ends with a hardish ball feeling thing is about 3/4 inches long.  It gets less hard as it moves away from the harder portion of the ball.
[|AI|]  Degree understand your concerns went through your details. I do understand your question. The vein like area under the gland of your penis, which is 3/4 of an inch long and hard, could be referred to "Corpus Spongiest".  The corpus spongiest is the mass of spongy tissue surrounding the male urethra within the penis. It is a mass of erectile tissue alongside the corpora caverns of the penis and terminating in the glans. I suggest you not to worry and obsess about its presence. For you to be satisfied, I suggest a consultation with a urologist. If you require more of my help in this aspect, please use this URL. http://goo.gl/aYW2pR.
