The negative effect on sperm motility was not due to necrozoospermia
Como criterios de exclusion se consideraron muestras con oligozoospemia severa, azoospermia, hemospermia, criptozoospemia, hipospermia, necrozoospermia
y astenozoospermia severa.
Main causes of male infertility include low sperm count (azoospermia and oligozoospermia), poor vitality (necrozoospermia), low motility (asthenozoospermia), low DNA integrity, and abnormal sperm morphology (teratospermia) (4, 5).
In contrast, if no detectable color change is observed, then that patient may be at high risk for azoospermia, oligozoospermia, necrozoospermia, or asthenozoospermia.
Oxidative stress has been implicated in a number of different reproductive scenarios such as endometriosis folliculogenesis oocyte maturation hydrosalpingeal fluid necrozoospermia
asthenozoospermia and sperm DNA damage (Guerin et al.
Sperm-viability testing typically uses a nuclear-exclusion stain to determine whether non-motile sperm are alive and not able to move, or actually dead (necrozoospermia
The terms used to describe samples with values lying outside the reference range were hypospermia for seminal volume; oligozoospermia for sperm concentration; asthenozoospermia for progressive motility; necrozoospermia
for sperm vitality; teratozoospermia for sperm morphology; and leukocytospermia .
An abnormal vitality may be caused by necrozoospermia
or prolonged abstinence.
