In this article, we will look at the functions and structure of the penis and how these give rise to certain clinical conditions. Note: In the anatomical position the penis is erect, so the dorsal side is that closest to the abdomen and the ventral side is closest to the testes. The root and body of the penis are spanned by three masses of erectile tissue.
By Sabine Walter, Pierre A. Knowing how a penis functions can provide useful insight into sex and the human body — whether you want to understand the penis and male anatomy better or learning about it for the first time. Basically, a penis is composed of three structures, which are made of a spongelike material that can fill with blood:.

The penis is composed of three cylinders encased in a sheath called the bucks fascia. These three cylinders are the corpus spongiosum and two corpora cavernosa known as the corpus cavernosum of penis. The corpus cavernosum contains spongy erectile tissue.
Penisthe copulatory organ of the male of higher vertebrates that in mammals usually also provides the channel by which urine leaves the body. The corresponding structure in lower invertebrates is often called the cirrus. The human penis is anatomically divided into two continuous areas—the body, or external portion, and the root.
