Male Penis Anatomy

The penis is located on the outside of the body and is the main part of the male reproductive system. It houses several parts of this system including the tubular structures that help carry semen and other fluids to the outside of the body.

The male reproductive system is made up of many parts that all work together to stimulate sexual activity and facilitate reproduction. Each part serves a specific purpose and is crucial in this process. The penis is among those parts and is one of the central locations for the various tubular structures that help make up this system.

The penis is made up of two parts: the shaft and the glands. The shaft serves as the main part of the penis, while the glands are located at the tip. This is usually the most sensitive part of the penis, and is important during sexual intercourse.

There is a small slip or opening located at the tip where semen and urine are excreted. This opening is connected to the tubular structures that help make this happen. These fluids exit the body through a tube called the urethra.

The inside of the male penis is made of a spongy tissue that can contract and expand as necessary. During an erection, the penis expands and becomes hard. When an erection is not present, the penis contracts and can become significantly smaller than when it is in an erected state. Erections can last for varying amounts of time, depending on the signals the brain receives. Sometimes it is eve impossible for a male to get an erection, but this is normally not cause for concern.

The penis is also the part of the male reproduction system that is physically used during sexual intercourse. Here, nerves are stimulated and sperm are dispensed. The other parts of the male reproductive system are connected to the penis through the various tubular structures located inside. The penis is also connected to the scrotum, the sack-like structure that holds the testicles .

The testicles produce and store the sperm, which is then transmitted through the penis. During sexual intercourse, they exit the body. The sack containing the testicles is also attached to the penis, and the various tubular structures that help transport sperm and other fluids outside the body.
