These stained immotile sperm were isolated in droplets and exposed to ultrasound (at a power of 800 mW and frequency of 40 MHz). After exposure, 34% of the live immotile sperm exhibited some form of motility , with no significant difference in responses between samples from different donors (fig. S6). For the remaining 66% of live immotile Sperm that show low motility or are immobile are not able to reach the egg to fertilize it, so sperm mobility is a fundamental sperm quality parameter to achieve a natural pregnancy.. It is analyzed through a semen analysis report and is considered to be altered when the number of progressively motile spermatozoa is less than 32% or the total number of motile spermatozoa in the ejaculate is Lastly, for most patients, the amount of immotile sperm cells in their samples was below 40 %, leading to a condensed data distribution. Nonetheless, immotile sperm cells were still quite reliably detected by our framework, yielding an R2 score of 66 %.

The immotile-cilia syndrome is a congenital disorder characterized by all cilia in the body being either immotile or showing an ineffective beating pattern. Most symptoms, not unexpectedly, come from the ciliated epithelia, but two further symptoms are: (1) male sterility caused by the spermatozoa being unable to swim progressively Immotile sperm. These are the sperm cells that do not show any movement at all. It's normal to have a small percentage of immotile sperm in a specimen. For a man to be fertile, he will need a total motility of at least 40%, and his sperm needs to have progressive motility of 32% or more 1.
