(A)spermia - complete lack of semen

(Asthenozoo)spermia - reduced sperm motility

(Azoo)spermia - absence of sperm cells in semen

(Hyper)spermia - large semen volume

(Hypo)spermia - small semen volume

(Oligozoo)spermia - few spermatozoa in semen

(Necrozoo)spermia - dead or immobile sperms

(Teratozoo)spermia - sperm with abnormal morphology

Asthenozoospermia (or asthenospermia) is the medical term for reduced sperm motility. Complete asthenozoospermia, that is, 100% immotile spermatozoa in the ejaculate, is reported at a frequency of 1 of 5000 men.^[1] Causes of complete asthenozoospermia include metabolic deficiencies, ultrastructural abnormalities of the sperm flagellum (see Primary ciliary dyskinesia) and necrozoospermia.^[1]

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.^[1] The percentage of viable spermatozoa in complete asthenozoospermia varies between 0 and 100%.^[1]
