Merevedése

Merevedése refers to the physiological process in males where the penis becomes engorged with blood, causing it to stiffen and enlarge. This phenomenon is a crucial component of sexual arousal and is essential for sexual intercourse.

The process is initiated by psychological or physical stimuli that trigger nerve signals from the brain and local nerves to the penis. These signals cause the smooth muscles in the penile arteries to relax, allowing more blood to flow into the corpora cavernosa, the two sponge-like chambers within the penis. Simultaneously, the veins that normally drain blood from the penis are compressed, trapping the blood within the corpora cavernosa and maintaining the erection.

Several factors can influence merevedése. Hormones, particularly testosterone, play a significant role in sexual desire and function. The health of blood vessels is also critical; conditions affecting circulation, such as cardiovascular disease or diabetes, can impair erectile function. Psychological factors like stress, anxiety, and depression can also have a negative impact.

The duration and firmness of merevedése can vary. It typically subsides when the stimulation ceases, allowing blood to flow out of the penis and return it to its flaccid state. Issues with achieving or maintaining merevedése are collectively known as erectile dysfunction.
