Volume eiaculata

normospermia - volume normale
aspermia - no semen (no or retrograde ejaculation)
hypospermia - Volume eiaculata < 1.5 mL
hyperspermia - Volume eiaculata > 6 mL
leuco(cito)spermia, piospermia - Leucociti > 1x106/mL

Numero spermatozoi

normozoospermia - eiaculato normale
azoospermia - no spermatozoa in semen (confirmed after centrifugation)
necrozoospermia - dead or immobile sperms
teratozoospermia - abnormal morphology
astenozoospermia - reduced sperm motility
astenoteratozoospermia - reduced sperm motility, abnormal morphology
oligozoospermia - few spermatozoa in semen
oligoteratozoospermia - few spermatozoa in semen, abnormal morphology
oligoastenozoospermia - few spermatozoa in semen, reduced sperm motility
oligoastenoteratozoospermia - few spermatozoa in semen, reduced sperm motility, abnormal morphology
criptozoospermia - "hidden sperm" (spermatozoa found only after centrifugation)
criptoteratozoospermia - "hidden sperm" (spermatozoa found only after centrifugation), abnormal morphology
criptoastenozoospermia - "hidden sperm" (spermatozoa found only after centrifugation), reduced sperm motility
criptoastenoteratozoospermia - "hidden sperm" (spermatozoa found only after centrifugation), reduced sperm motility, abnormal morphology
polyzoospermia - high concentration (>250000000/ml)
