Anatomy of the erect penis

The penis consists of three main structures: the corpora cavernosa, corpus spongiosum, and tunica albuginea. The corpora cavernosa, which is filled with spongy tissue extends along the length of the penis. Tunica albuginea is a membrane that covers and protects the corpora cavernosa. Spongiosum, in the middle of the penis, urethra houses, opening at the end of the penis through which a man urinating and ejaculation. There is also a network of tissues, muscles, arteries and veins pass through the penis, allowing it to fill with blood and stiffness for an erection.

Man reaches the penis is erect from the stimulation, such as touching or rubbing the penis, or see or think about something sexually stimulating and exciting. When stimulation occurs, the brain takes over and runs with the nerve endings in the penis. The brain and the nerves to send messages to the penis to relax, which increases blood flow to the veins and arteries in the penis.

Blood fills the penis, leading to pressure, which is contained and supported by the tunica albuginea. Blood entering the penis is essentially locked in for the supporting tissues and membranes, which allows pressure to be maintained, creating and holding an impotence. The testes also release the hormone testosterone, which plays a role in determining when an erection is as firm and it is.

Erection goes away when the penile muscles to tighten and stop blood flow to the penis. This usually occurs after orgasm and once in the stimulation, no longer exists.

Erectile dysfunction can occur for various reasons, including the sensitivity of the nerve, circulatory problems and other problems with blood flow, slowed heart rate and low production of testosterone.

If you have a neurological problem that affects communication between the brain and nerves of the penis, erectile dysfunction can occur. If you have high blood pressure or take medicines to treat high blood pressure, blood flow and circulation can be affected, making it difficult to achieve an erection, because not enough blood flowing to fill the penis. Diabetes can cause circulatory problems that impede blood flow and nerve damage, which receive messages from the brain signal the penis to relax and fill with blood.

Psychological problems like depression, fear and anxiety about sex and sexual activity may also affect the process of sexual arousal and messages sent to the brain.
