Anatomy of a Penis

The penis is a complex organ comprised of tissue, muscle, veins, arteries, and nerves. It begins inside your body near your prostate gland. Your penis serves many important purposes and has a variety of parts.

Corpora Cavernosa

For an erection, the most important part is the Corpora Cavernosa. These are two cavities that run the length of your penis and actually fill with blood to create an erection. Basically, the penis is a "hydraulic" machine.

Glans Penis

The glans penis (or simply glans) is the sensitive bulbous part the end of the penis, opposite of the base. This is commonly referred to as the "head" of the penis. When the penis is flaccid, the glans is covered by the foreskin, unless the individual is circumcised.


The uretrha is a tube that connects the bladder to the outside of the body, allowing urine to exit the body. In males, the urethra also allows for semen to be passed.

Corpus spongiosum

The corpus spongiosumndis is the mass of spongy tissue surrounding the male urethra within the penis.

Erectile Dysfunction

In order to achieve a good erection, there are several factors that come into play such as a clear mind, functional nerves, and hormones. If you're having problems getting an erection or maintaining one, these are some reasons why it might be occurring:

  • Trauma - If there is any nerve damage to your pelvic region, this may cause ED.
  • Clear mind - As silly as it might sound, your brain has a lot to do with an erection. If something is on your mind that is interfering with nerve messages delivering blood to your penis, ED can occur.
  • Medications - Certain medications can prevent the proper signals that drive blood to the penis, such as blood pressure medicines.
  • Diet - People that lack the appropriate intake of calories can cause problems with having a properly functioning penis, which can be the case if you've recently been ill or are still ill and have not eaten much.

Treatment is highly possible, so please consult a doctor if you are having Erectile Dysfunction problems. Remember, Viagra and Cialis exist for a reason! To read more about ED, here's a good article to read.
