how does a sperm obtain energy for. it's motility
Answers
Answer:
Hello mate
Explanation:
In addition, spermatozoa are highly motile and consume considerable amount of energy. Spermatozoa utilize energy on motility, which is primarily in the form of intracellular ATP generated by oxidation of substrates, fructose, glucose, sorbitol, lactate, or pyruvate.
●Sperm motility generally reflects the viability of a sperm population. A positive relationship between sperm motility and fertilizing capacity has been shown in many species, although this correlation is not absolute. Several different instruments and methods have been developed for objective assessment of equine sperm motility, including time-lapse photomicrography, frame-by-frame playback videomicrography, spectophotometry, and computerized analysis . Computerized motility analysis provides a number of objective measures of sperm motion characteristics taken from tracks of large numbers of sperm, including percentage of motile sperm, percentage of progressively motile sperm (i.e., above a preset cutoff for speed and direction of movement), amplitude of lateral head displacement during forward movement, average path velocity in micrometers per second, and curvilinear velocity in micrometers per second. Subjective assessment of sperm motility via visual estimation, with a microscope equipped with phase-contrast optics and a warming stage (see Figure 12-18), is acceptable when personnel are experienced in analysis of sperm motility.
