Primary ciliary dyskinesia PCD , is a rare, ciliopathic , autosomal recessive genetic disorder that causes defects in the action of cilia lining the respiratory tract lower and upper, sinuses , Eustachian tube , middle ear , fallopian tube , and flagellum of sperm cells. The phrase "immotile ciliary syndrome" is no longer favored as the cilia do have movement, but are merely inefficient or unsynchronized. Respiratory epithelial motile cilia , which resemble microscopic "hairs" although structurally and biologically unrelated to hair , are complex organelles that beat synchronously in the respiratory tract, moving mucus toward the throat. Normally, cilia beat 7 to 22 times per second, and any impairment can result in poor mucociliary clearance , with subsequent upper and lower respiratory infection. Cilia also are involved in other biological processes such as nitric oxide production , currently the subject of dozens of research efforts.

Causes of Male Infertility | Metromale Clinic & Fertility Center

Even though most cases of infertility are complex and involve multiple factors, some of which are known, while others can only be speculated, the more that we can pinpoint, the better. One of the most common sources of male infertility is low sperm motility. Low sperm motility refers to the inability of the sperm move quickly and efficiently toward their desired destination, the egg. Among men with low sperm motility, the majority of the sperm are too slow and haphazard in their motion to make it to the egg; in fact, most probably do not make it past the vaginal canal. Those that do usually die immediately.

Asthenozoospermia or asthenospermia is the medical term for reduced sperm motility. It decreases the sperm quality and is therefore one of the major causes of infertility or reduced fertility in men. A method to increase the chance of pregnancy is ICSI. Sperm DNA fragmentation level is higher in men with sperm motility defects asthenozoospermia than in men with oligozoospermia or teratozoospermia.
