Corpus Cavernosum Tissue: Facts About Its Size, Function & More
The corpus cavernosum is a pair of spongy tubes that runs along the length of each side of the penis. It plays an essential role in achieving and maintaining an erection during sexual arousal. During an erection, blood flow into the corpora cavernosa increases while the smooth muscles relax, allowing the corpora to expand and trap more blood inside them. This causes the penis to become stiff and rigid, which allows for penetration during intercourse. In this article, we will explore what the corpus cavernosum does during an erection and some key facts about its size and function.
Function of Corpus Cavernosum Tissue
When a man becomes sexually aroused, nerve impulses are sent from his brain to the corpora cavernosa, causing it to fill up with blood. The blood flows into the corpora through the sinusoids, small veins that allow the blood to pass through without much resistance. As the corpora fills up with blood, pressure builds up, and the tunica albuginea, a sheath surrounding the corpora, expands. When there's enough blood in the corpora, the tunica albuginea keeps the blood trapped until the man orgasms or loses his erection. Once the erection ends, blood leaves the corpora slowly, reducing its size back to normal.
Size of Corpus Cavernosum Tissue
On average, the corpora cavernosa makes up 40%-50% of the total penile length. However, it can vary widely depending on factors such as age, weight, height, and ethnicity. For example, men who are overweight may have larger corpora than those who are not.
Factors That Affect Corpora Cavernosa Size
Several factors can affect the size of the corpora cavernosa, including:
Age - As a man gets older, he may experience changes in the size of his corpora cavernosa due to hormonal changes and decreased elasticity.
Weight - Men who are overweight or obese tend to have larger corpora cavernosa due to increased tissue mass.
Ethnicity - Studies show that African American men tend to have smaller corpora cavernosa than Caucasian men.
Penis Enlargement Surgery - Penis enlargement surgery involves increasing the girth and length of the corpora cavernosa through injectable fillers or fat grafting. While this procedure can be effective for some men, it comes with risks like scarring, discoloration, and infection.
Corpora Cavernosa Lengthening Procedure - This is a newer type of penis enlargement surgery that involves removing excess fat from one part of the penis and transplanting it into the corpora cavernosa. The surgery can help increase both the length and girth of the penis but also carries risks like complications from anesthesia and infections.
In conclusion, the corpus cavernosum plays a crucial role in achieving and maintaining an erection during sexual arousal. Its size and function can vary depending on various factors such as age, weight, height, ethnicity, and the type of penile enhancement procedure used. Understanding these facts about the corpus cavernosum can help men better understand their own bodies and make informed decisions about their healthcare needs.
