The condition of becoming rigid and elevated as in an of the penis.
A state where a body part such as the penis becomes swollen because of engorgement with blood.
State of rigidity, especially of the penis, which becomes enlarged and elevated when its tissues fill with blood usually as a result of sexual arousal but also occurring normally during sleep and as a result of physical stimulation. Erection of the penis enables the penis to enter the vagina during coitus.
The rising and hardening of the penis due to blood accumulating in its tissues. During sexual stimulation, blood fills the erectile bodies of the penis, which are closed by exit valves in the veins to keep the blood in rather than let it flow out. A similar process hardens and raises the clitoris. Erection is also used to describe the rising of other tissues, such as the nipple or fine hairs on the skin, that stand up from muscular contraction rather than from the accumulation of blood.
The sexually active state of the penis, which becomes enlarged and rigid (due to the erectile tissue being swollen with blood) and capable of penetrating the vagina. The term is also applied to the clitoris in a state of sexual arousal.
The rigid state of the penis when it responds to sexual stimulus. An erection is necessary for effective penetration of the vagina. As a result of sexual arousal, the three cylinders of erectile tissue in the penis become engorged with blood, lengthening, raising and hardening the penis. Muscles surrounding the blood vessels contract and retain the blood in the penis. Erections also occur during sleep and in young boys. Inability to have or maintain an erection is one cause of impotence.
The state of swelling, hardness, and stiffness observed in the penis and to a lesser extent in the clitoris, generally due to sexual excitement. It is caused by engorgement with blood of the corpora cavernosa and the corpus spongiosum of the penis in men and the corpus cavernosa clitoridis in women.
An erection refers to the stiffness, enlargement, and elevation of the penis that happens due to sexual arousal or physical stimulation. During an erection, the erectile tissue of the penis fills with blood as the blood vessels within it widen. The surrounding muscles then tighten to keep the blood in the penis, which sustains the erection.
Refers specifically to the change in the penis where it becomes engorged with blood, achieving an erect and rigid state.
