Erekcj

Erekcj is not a standard entry in English or Polish dictionaries; it appears to be an incomplete form of the Polish word erekcja, which means erection. This article provides a concise overview of the physiological phenomenon commonly described as an erection in humans.

Erection is the penile engorgement with blood resulting in stiffening of the penis, typically during sexual arousal. The process involves the nervous system, blood vessels, and erectile tissue. Sexual arousal triggers the release of nitric oxide, which relaxes smooth muscle in the corpora cavernosa and corpora spongiosum. This relaxation allows blood to flow into the spaces, while the tunica albuginea helps trap the blood, creating rigidity. Venous outflow is reduced during erection, helping to sustain it. Erection also occurs in females, where clitoral tumescence may accompany sexual arousal and lubrication.

Most erections end with detumescence as sympathetic activity returns to baseline. Persistent difficulty achieving or maintaining an erection is known as erectile dysfunction (ED) and can reflect health issues such as cardiovascular disease, diabetes, hormonal imbalance, medications, or psychological factors. Evaluation typically includes medical history, physical examination, and, when indicated, laboratory tests. Treatments range from lifestyle changes and psychotherapy to medications (for example PDE5 inhibitors), devices, or surgical options in some cases.
