Although a moving or motile sperm was traditionally required for use with this technique, some infertile men have genetically immotile sperm and are unable to take advantage of this technology to become fathers.

Disconnected from their originating immotile groupings, Beta's Primes started to routinely alter themselves through genetic manipulation and mechanical augmentation and therefore were referred to as " alienPrimes " by the Alpha Primes.

Human resistance forces have found two ways to fight back : using the Prime weapons ( primarily directed-energy weapons ) against the invaders, and disrupting communication between the slave caste ( motiles ) and the commanding caste ( immotiles ) of the Primes.

Although ciliopathies are usually considered to involve proteins that localize to motile and / or immotile ( primary ) cilia or centrosomes, it is possible for ciliopathies to be associated with proteins such as XPNPEP3, which localizes to mitochondria but is believed to affect ciliary function through proteolytic cleavage of ciliary proteins.

In early research in this area, Turek tried to understand more about how sperm viability relates to motility . " Subsequently, his team evolved the Hypoosmotic Swelling Test into a therapeutic tool that harmlessly and physiologically pokes a non-moving sperm to determine whether it is alive and therefore able to be used for ICSI . This technique was subsequently applied to men with genetically immotile sperm with success and this technique is now used routinely in many reproductive centers worldwide.
