Impaired movement of sperm
This measures many features of the sperm and semen the fluid in which the sperm are contained. The most important of these are the number of sperm sperm count , motility of the sperm percentage of moving sperm , morphology of the sperm percentage of normally shaped sperm , and the volume of fluid. To assess sperm morphology, the sperm are examined under a microscope and the percentage of abnormally shaped sperm is estimated. Sperm morphology is assessed using one of 2 sets of characteristics.

Stress degrades sperm quality, study shows
Sperm motility - Wikipedia
Back to Pregnancy and child. The research behind this news was a two-part study that first tested the blood vitamin D levels and sperm motility of Danish men taken from the general population. The second part then looked at what happened when vitamin D was added to sperm samples from an additional 40 men. The researchers found vitamin D raised calcium levels in the sperm and that, in turn, increased their motility and the proportion of the sperm undergoing the changes needed to fuse with a female egg. This study shows that vitamin D can have an effect on sperm, but further work is needed to see whether the amount of vitamin D used in the experimental phase of this study reflects the range of vitamin D that sperm would typically be exposed to in the human body.

How does sperm motility affect fertility?
Correspondence Address : Dr. It has been suggested that the energy required for sperm motility is produced by oxidative phosphorylation while glycolysis seems to be an important source for ATP transmission along the flagellum. Some studies have investigated the chemical and kinetic properties of the enzyme glyceraldehyde 3-phosphate dehydrogenase to identify any changes in the regulation of glycolysis and sperm motility.
