(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]
