Ejaculation
|
|
Ejaculation Ejaculation is the process of ejecting semen from the penis, and is usually accompanied by orgasm as a result of sexual stimulation. It may also occur spontaneously during sleep (called a nocturnal emission), due to stimulating of the prostate or, rarely, due to prostatic disease.

Ejaculation
Ejaculation is the process of ejecting semen from the penis, and is usually accompanied by orgasm as a result of sexual stimulation. It may also occur spontaneously during sleep (called a nocturnal emission), due to stimulating of the prostate or, rarely, due to prostatic disease.
Semen
The fluid containing sperm (the male reproductive cells) that is expelled (ejaculated) through the end of the penis when the man reaches sexual climax (orgasm).
Penis
The male sex organ, which consists of a head called glans, and the shaft or body. At the tip of the glans is the urethral opening, through which urine and semen leave the body. The shaft or the body of the penis is made of spongy tissue and blood vessels. And it fills with blood an grows in size (becomes erect) during sexual excitement.
Orgasm
An intense sensation that occurs at the climax of sexual excitement that is accompanied by rhythmic muscle contractions and intense pleasure, followed by release of sexual tensions. In men, orgasm is usually accompanied by ejaculation.
Sexual
Pertaining to sex or, more particularly, the stimulation, responsiveness, and functions of the sex organs either alone or with one or more partners.
Prostate
A male sex gland that produces a thick fluid which forms part of semen.
Disease
Illness or sickness often characterized by typical patient problems (symptoms) and physical findings (signs). Disruption sequence: The events that occur when a fetus that is developing normally is subjected to a destructive agent such as the rubella (German measles) virus.
SIMILAR TERMS--------------------------------------
Ejaculate
The fluid emitted from a man's penis that contains sperm.
Ejaculatory duct
A canal in the male formed by union of the vas deferens and the duct from the seminal vesicle. The ejaculatory duct passes through the prostate. Semen passes through them at the time of ejaculation.
PREVIOUS AND NEXT TERMS--------------------------------------
Epithelium
A thin layer of cells that covers the internal and external surfaces of the body, including body cavities, ducts and vessels.
Erythrocyte
An erythrocyte is more commonly known as a red blood cell, which is the most numerous type of blood cell. Erythrocytes contain the red pigment hemoglobin and are responsible for oxygen transport. In humans, the number of erythrocytes in the blood varies between 4.5 and 5.5 million per cubic millimeter. They survive for about four months and are then destroyed in the spleen and liver.
Ejaculation
Eukaryotic
The living world is divided into two classes of organism. Eukaryotic and, much simpler, prokaryotic organisms such as bacteria. Generally eukaryotes are diploid and their cells have internal organelles, such as nuclei. Prokaryotes are haploid with much simpler cells.
Enzyme
A cellular protein whose shape allows it to hold together several other molecules in close proximity to each other. In this way, enzymes are able to induce chemical reactions in other substances with little expenditure of energy and without being changed themselves. Basically, an enzyme acts as a catalyst.
Eicosanoid
A hormone derived from a polyunsaturated fat. Eicosanoids are made by every cell in the body. As autocrine hormones, they are constantly produced by the cell to sample the external environment. "Good" eicosanoids generate AMP.
Endocrine hormones
Hormones that are secreted from a discrete gland and then travel through the bloodstream to target tissues.
Endocrinology
The study of hormones. A more inclusive definition would be the study of biological communications.
