Sædutløsningen

Sædutløsningen, also known as ejaculation, is the process by which semen is expelled from the penis. This occurs during sexual arousal and typically accompanies orgasm. The process is a complex physiological reflex involving the nervous system and muscular contractions.

During sexual stimulation, nerve signals are sent to the spinal cord and then to the reproductive organs. This leads to two main phases: emission and expulsion. In the emission phase, sperm from the testes and fluids from the seminal vesicles and prostate gland are collected in the urethral bulb at the base of the penis. This is often felt as a sensation of "ejaculatory inevitability."

The expulsion phase involves rhythmic contractions of the muscles in the pelvic floor and at the base of the penis. These contractions forcefully propel the semen through the urethra and out of the penis. The frequency and volume of semen can vary between individuals and with age.

Sædutløsningen plays a crucial role in reproduction, as it delivers sperm into the female reproductive tract. It is a natural and healthy bodily function. In some medical contexts, issues related to sædutløsningen, such as premature or delayed ejaculation, may be discussed.
