ejakulatsioon

Ejakulatsioon, also known as ejaculation, is a physiological process in which semen, the fluid containing sperm and other secretions, is released from the male reproductive system during orgasm.

During sexual arousal, the seminal vesicles and prostate gland produce a mixture of secretions, which are stored in the urethra. As orgasm approaches, the smooth muscle in the penis, known as the corpus cavernosum, contracts and relaxes, creating a build-up of pressure in the urethra.

Eventually, the pressure becomes too great, and the muscles in the pelvic floor contract, causing the semen to be released through the urethral opening at the tip of the penis. This process is usually accompanied by feelings of intense pleasure and relief.

Ejaculation can occur through sexual intercourse, masturbation, or nocturnal emissions, which occur during sleep. It is a natural and essential part of human reproduction, allowing for the transfer of sperm during copulation.

Research has shown that healthy males typically experience an average of 2-4 ejaculations per week, with a normal range of 1-13 per week. Factors such as age, physical health, and psychological well-being can influence the frequency and timing of ejaculation.

In some cases, ejaculation may be affected by medical conditions, medication, or lifestyle choices. These include conditions such as premature ejaculation, delayed ejaculation, and erectile dysfunction, which may require medical attention or counseling to resolve.
