Male Ejaculation Consists of Two Phases: Emission and Expulsion
Male ejaculation is an important part of male sexual functioning. It involves two distinct phases: emission and expulsion. In this article, I will provide a comprehensive explanation of these two phases, including their physiology, psychological components, and potential medical conditions that can affect them.
Emission refers to the process by which spermatozoa are released from the epididymis into the vas deferens. This occurs when seminal vesicles produce semen, which then mixes with the sperm cells. The semen contains proteins, fructose, citric acid, and enzymes that help keep the sperm alive for up to five days after being deposited into the female reproductive tract. Sperm travel through the vas deferens towards the urethra, where they are stored until orgasm.
Expulsion is the second phase of male ejaculation. It involves the contraction of the pelvic floor muscles, which forcefully pushes the semen out of the body through the penis. This phase is triggered by the sympathetic nervous system, which sends signals to the brain to initiate a series of muscle contractions in the pelvis. These contractions create the rhythmic motion of the pelvic thrusts during sex.
The psychological component of male ejaculation is also significant. Men who experience anxiety or performance-related issues may have difficulty achieving a satisfactory orgasm. For example, men who worry about premature ejaculation (PE) may feel anxious during sex and try to control their urge to climax too quickly. As a result, they may not be able to fully enjoy the physical pleasure of expelling semen.
There are several medical conditions that can affect male ejaculation. One common condition is retrograde ejaculation, in which semen enters the bladder instead of exiting through the penis. This occurs when the bladder and prostate muscles do not close properly, allowing semen to flow backward. Another condition is anejaculation, in which a man cannot ejaculate despite having an orgasm. This can be caused by various factors, including medications, surgery, or nerve damage.
In conclusion, male ejaculation consists of two distinct phases: emission and expulsion. Understanding these phases can help men improve their sexual functioning and enjoyment. However, certain medical conditions can interfere with ejaculation and require treatment. By educating ourselves on this topic, we can better understand our bodies and improve our relationships.
