How does our body work?

The penis is part of the male reproductive or sexual system, which includes body parts like the scrotum and testicles. In order to understand how the penis works, it can help to think of it in two parts – the outside and the inside.

On the outside, the shaft of the penis is covered by a thin layer of skin that is loose when un-aroused or flaccid. On the inside, the urethra runs through the middle of the penis, a tube that ends at the top of the head, or glans penis, where a slit-like vertical opening can be seen. Essentially, the urethra connects the bladder and the prostate gland with the end of the penis and plays a key role in men’s sexual health.

The internal sphincter, a muscle located at the base of the bladder,stops urine and semen from leaving the penis at the same time. When an orgasm occurs, the muscle shuts tightly to prevent urine from passing through the urethra at the same time, and to prevent sperm from passing ‘backwards’ into the bladder.


How does ejaculation occur?

Ejaculation is controlled by the body’s central nervous system and occurs when sexual stimulation is combined with a certain degree of friction. This creates impulses that are sent to the spinal cord and up into the brain. The brain then sends signals back down the spinal cord to the genital area. These signals cause the pelvic muscles to start contracting.

When this happens, phase one of ejaculation kicks in: the tubes that store and transport sperm from the testicles (or testis) start to contract to squeeze the sperm through the prostate gland and towards the base of the penis. Once this occurs, ejaculation becomes an unstoppable force and the process moves on to phase two, when muscles at the base of the penis begin to contract to force the semen up through the urethra and out of the penis.

What is male orgasm?

For males, an orgasm is an intense and highly pleasurable feeling of release that occurs at the peak of sexual excitement. Although it is true that a man usually ejaculates at the time of orgasm, the two acts are not the same thing.


Is there a difference between male ejaculation and male orgasm?

While the words orgasm and ejaculation are often used interchangeably, they are two different processes that usually happen simultaneously.

Ejaculation is when there is an expulsion of semen from the penis. Orgasm produces a strong sensational rush over the body. However, it is possible for men to experience orgasm without ejaculation and vice versa.
