The penis is an integral part of male reproductive system that plays a vital role in sexual intercourse. It is composed of three main parts including corpora cavernosa, corpus spongiosum, and glans penis. It receives its blood supply from various sources including cremasteric arteries, bulbourethral arteries, and dorsal arteries. Out of these, dorsal arteries are one of the most important ones which carry rich blood supply to the penis. These arteries originate from internal pudendal artery and run along the length of penile shaft providing a rich blood supply to the penis tissue. This article will discuss about the importance of dorsal arteries in terms of their functioning and contribution to erection.
The dorsal artery is also known as penile artery due to its location in the penis. It runs along the length of the penile shaft supplying blood to it. The dorsal artery branches out into two types of arteries called lateral and median arteries. The lateral arteries supply blood to the left and right sides of the penis while the median artery supplies blood to the central region of the penis. Both the lateral and median arteries eventually merge together to form the dorsal vein which carries blood away from the penis.
During sexual arousal or stimulation, the brain sends signals to the smooth muscles present in the corpora cavernosa which causes them to relax and expand leading to an increase in blood flow to the penis. This increased blood flow helps in creating rigidity and stiffness in the penis for optimal sexual performance. The dorsal artery plays a crucial role in this process by delivering a rich blood supply to the penis during arousal. Without proper blood flow to the penis, it becomes difficult to achieve an erection and have sexually satisfying experiences.
Apart from that, the dorsal artery also provides oxygenated blood to the penis which is necessary for maintaining the healthy condition of the penis. Oxygen-rich blood ensures that the cells remain active and viable throughout the day. Furthermore, it facilitates the removal of waste products like carbon dioxide from the penis tissue which is essential for normal functioning.
In conclusion, the dorsal artery has significant importance in terms of providing a rich blood supply to the penis. It contributes immensely in achieving and maintaining an erection as well as keeping the penile tissues healthy. Therefore, any damage to these arteries can lead to erectile dysfunction which makes sex difficult or impossible for men.
