Hyperactivated Motility in Sperm

Journal of Andrology, 1996
The functions of hyperactivation may fit together to create the following scenario. Sperm that enter the oviduct bind to the mucosal epithelium. Near the time of ovulation, hyperactivation helps them to detach from the epithelium, escape mucosal pockets, and move through oviductal mucus.

Sperm Motility, Velocity and Migration

British Journal of Urology, 1990
Summary— Four different methods for evaluating sperm motility were analysed for experimental error: subjective assessment of a wet film preparation, sperm velocity measured by time‐lapse photography, sperm velocity measured by computer analysis and sperm migration across a nucleopore membrane.

Sperm Motility Assessment by Videomicrography

Fertility and Sterility, 1981
A technically simple, inexpensive method is described for measuring objective parameters of sperm motility. The instruments involved are commercially available, home-oriented videotape equipment. Quantitative measurements of sperm motility are made directly from the video image and are facilitated by use of an analysis transparency that is applied as ...

Bacterial effect on sperm motility

Urology, 1975
Human semen containing normal number of sperm was exposed to concentrations of Escherichia coli varying from 500 to 10-8 colonies per cubic centimeter. A significant decrease in motility was abserved at 10-6 colonies per cubic centimeter.

Automatic sperm motility measurement

2015 International Conference on Information Technology Systems and Innovation (ICITSI), 2015
Sperm quality can be measured by sperm count, vitality, morphology, motility, etc. Unfortunately, it is very hard to assess sperm quality manually especially sperm motility. To overcome this, researchers developed Computer-Aided Sperm Analysis (CASA). This device was still an expensive one so that only big medical laboratories used it.
