Ejaculation is the release of semen from the penis due to sexual stimulation during sex.

Ejaculation occurs when the semen is released from the prostate to the seminal vessels. After the semen is released, the muscles around the urethra push the semen through the urethra and out of the penis.

Sexual arousal causes nerves in the penis to send chemicals through the spinal cord to the brain. When a man reaches a certain level of excitement during this process, chemical and nerve messages sent from the brain to the pelvis cause the process of ejaculation. While it is not completely understood, medical researchers believe that the chemical serotonin released in the brain is a substantial component to the feeling of euphoria created during and after sex in men.
