Ejaculation is the release of semen from the penis during orgasm. It's a normal part of male sexual functioning that can be pleasurable for both partners. Ejaculation involves rhythmic contractions of the pelvic muscles, which force semen out of the urethra and through the tip of the penis. The exact timing of these contractions varies between individuals but typically lasts around 2-10 seconds. Semen consists of sperm cells, fluids, and enzymes that help transport the sperm to an egg cell.
There are three phases of ejaculation: emission, plunger phase, and expulsion phase. During the emission phase, seminal fluid begins to accumulate in the prostate gland and mix with secretions from the seminal vesicles. This mixture travels up the vas deferens to the urethra, where it coats the walls of the urethra and forms a thick white substance known as "pre-ejaculate." In the plunger phase, smooth muscle contractions compress the prostate gland, pushing the pre-ejaculate out of the urethra. In the expulsion phase, more powerful pelvic floor muscle contractions propel semen at high velocity towards the tip of the penis, resulting in a distinctive sensation and sound often described as "shooting" or "explosion."
During sex, men may choose to delay their own or their partner's ejaculation by using techniques such as the stop-start method, squeeze method, or edging. Delayed ejaculation can enhance sexual pleasure for both partners and allow them to focus on other activities during intercourse. However, some men may experience premature ejaculation (PE), which occurs before they want it or is inconsistent with how long they would like. PE can be caused by various factors, including stress, anxiety, medical conditions, or medications. Treatments include behavioral therapy, medication, and lifestyle changes. Ejaculatory disorders are common but treatable.
In conclusion, ejaculation plays an important role in male sexual health and well-being. Understanding how it works can help individuals optimize their sexual experiences and address any issues that arise.
