Refers to how active the sperm cells are - that is, how much they move or "swim." The more the sperm swim, the greater the chance they will reach their goal: the egg. Most sperm banks conduct a sperm analysis to measure motility, and only accept donors whose sperm meets a minimum standard of motility.

The percentages of all moving sperm in a semen sample.

(noun) movement, as in the movement of food or waste through the gastrointestinal tract.

The ability of sperm to swim. Poor motility means the sperm have a difficult time swimming toward the egg.

a change of position that does not entail a change of location; "the reflex motion of his eyebrows revealed his surprise"; "movement is a sign of life"; "an impatient move of his hand"; "gastrointestinal motility"

The power of movement. Usually used to describe sperm, which move under their own power.

The coordinated neuromuscular activity of the wall of the GI tract that moves intestinal contents.

The ratio of motile (moving) to immotile (not moving) sperm, expressed in percent.

A term used in semen analysis to describe the movement of sperm. The percentage of sperm swimming is assessed and the speed with which they are progressing is measured.

Motility is the percentage of sperm actively swimming around. At least 50% of the sperm should be motile. Only the sperm that are able to swim quickly to the egg and fertilize it are of any use when trying to conceive a pregnancy.

Spontaneous movement. A term used to describe the motor activity of smooth muscle in the gastrointestinal (GI) tract.

movement of food through the digestive tract.

movement of the sperm. Less motility means less chance of fertility.

Pertaining to movement

In a semen analysis, the degree to which sperm cells are able to spontaneously propel themselves

Refers to the swimming ability of the sperm. close window

Movement of the muscles that propel food through the intestinal tract.

The term to describe the movement of food throughout the digestive tract.

Contractions of the muscles in the digestive tract that promote mixing and movement of digestive contents.

The designation of the quality of sperm movement.

Movement of the eye by muscles

The percentage of all moving sperm in a semen sample. Normally 50% or more are moving rapidly.

Motility is the power to move spontaneously.

mothion, such as the forward swimming motion of health sperm

The movement or capacity for movement of an organism or body organ. Indigestion is sometimes caused by abnormal patterns in the motility of the stomach.

The measurement of motion and forward progression of sperm in a semen analysis.

The ability of the digestive tract to propel its contents (see Digestive Health).

Capacity for spontaneous movement, frequently in reference to the intestine.

The percentage of all moving sperm in a semen sample. Normally, 50% or more sperm in a sample move rapidly.

Motion, such as the forward swimming motion of health sperm.

Percent of sperm in a specimen that are alive and moving.

Ability to move.

The nature of a sperm's movement

The quality of movement, especially forward propulsion, shown by sperm cells (spermatozoa) and caused by effective beating of their tail, or flagellum. Analyzed as part of the routine sperm count.
