The Penis is a Male Reproductive Organ
The penis is one of the male reproductive organs responsible for the discharge of semen, reproduction, and urination. It is also known to have an external shaft which houses its spongy tissues and a glans at the tip. This organ plays a crucial role in the process of procreation since it enables men to pass sperm into women's bodies. However, did you know that the penis has no bones? In this article, I will discuss the absence of bones in the penis and how they affect its functionality during erections.
What are Bones Made Of?
Bone is a living tissue found in vertebrates like fishes, amphibians, birds, mammals, and reptiles. Its basic structure includes collagen fibers and calcium phosphate crystals, creating a mineralized matrix that provides structural support. Bone cells called osteoblasts produce bone tissue through a process called ossification. During this process, they secrete collagen fibers and calcium phosphate crystals to form bony structures that provide rigidity and strength.
Why Does The Penis Lack Bones?
Scientists believe that the absence of bones in the penis may be due to its evolutionary adaptation from ancestral aquatic creatures with gills who lived in water and required less rigid skeletons. When they evolved into land animals, their bodies adapted to the new environment by developing stronger muscles, tendons, ligaments, and cartilages to support them against gravity. As such, the male penis lacks bones but contains other connective tissues, including cartilage, which makes it flexible for sexual arousal and urination.
Erectile Tissue: How It Works
The penis consists of three spongy cylindrical tubes filled with erectile tissue known as corpora cavernosa. These tissues become engorged with blood when a man gets sexually excited or aroused, resulting in an erection. Arteries carry blood to the corpus cavernosum, while veins drain out blood after orgasm. Erections can last up to 30 minutes before subsiding. However, without bones, the penis is prone to injuries and fractures during rough intercourse or mishandling.
Softness vs Rigidity
During an erection, the penis becomes stiff and hard because of the increased flow of blood into the corpus cavernosum. This process causes the tissues to swell and trap more blood, making the organ firm. The penis then remains erect until the body returns to normal levels, and the blood flows out through veins. Men can get aroused and stay hard for long periods, depending on their physiological state. Without bones, this process occurs naturally and does not require any assistance from bones.
In summary, the absence of bones in the penis allows it to be flexible and absorb shock during sexual activity. Its softness enables easy movement, making it easier to penetrate women's vaginas. In addition, its lack of rigidity reduces the chances of injuries and fractures that could occur if there were bones. Thus, the male reproductive system has evolved to adapt to changing environments and circumstances for better functionality.
