Erectile tissue is tissue in the body with numerous vascular spaces, or cavernous tissue, that may become engorged with blood. [1] [2] However, tissue that is devoid of or otherwise lacking erectile tissue (such as the labia minora, vestibule, vagina and urethra) may also be described as engorging with blood, often with regard to sexual arousal.
When a large amount of blood flows to the genital region, the penis becomes erect and the testicles also experience increased blood flow and swelling. [4] In the vulva, the blood flow increases in erectile tissue, causing it to expand. After orgasm, the tissue shrinks back to its initial size as most of the blood leaves.
An erection (clinically: penile erection or penile tumescence) is a physiological phenomenon in which the penis becomes firm, engorged, and enlarged. Penile erection is the result of a complex interaction of psychological, neural, vascular, and endocrine factors, and is often associated with sexual arousal, sexual attraction or libido, although erections can also be spontaneous.
This molecule plays a key role in relaxing the smooth muscle tissue that controls blood flow to the erectile tissue inside your penis. During this process, an amino acid produced by the body, L ...
Drinking plenty of water promotes blood flow to the penis, while also ensuring you have enough energy to last in bed. As for what to avoid in your diet—Elist suggests limiting processed foods ...
During sexual arousal, arterial blood flow to the clitoris is increased, and within the clitoris, the arteries further branch to supply the erectile tissues. The trabecular smooth muscles of the erectile tissue relax increasing blood flow to fill the vascular spaces, and expanding the erectile tissues until they are fully engorged with blood. [7]
Most FDA-approved prescription-only medications have a clearly understood mechanism of action for increasing blood flow to the privates. Currently, there are four FDA-approved prescription oral drugs.
Functional hyperaemia is an increase in blood flow to a tissue due to the presence of metabolites and a change in general conditions. When a tissue increases its activity, there is a well-characterized fall in the partial pressure of oxygen and pH, along with an increase in partial pressure of carbon dioxide, and a rise in temperature and the concentration of potassium ions.
