HOW MANY SPERM?
The two most important aspects of the sperm count are the actual numbers of sperm per cc and their motility, ie the speed and the
quality of their movement.
Motility of the Sperm.
More important than the quantity of sperm is the quality and activity of those sperm. Determining percentage are Sperm that are moving and those not
moving is another important parameter. There are always a certain number of dead, non
motile sperm in the ejaculate. These
nonmotile sperm are incapable of
fertilization. Only the moving sperm
are capable of entering the egg. After the percent motility is determined (that is, the
percentage of moving sperm), it is recorded as follows:
- Grade I motility means that the sperm
are only wiggling sluggishly in place and making very little, if any, forward progression.
These pathetic vibratory-type movements get the sperm nowhere and such sperm are incapable of fertilizing the egg, resulting in pregnancy.
- Grade II motility means that the sperm
are moving forward, but either the speed is very slow or they do not move in a straight
line. The sperm that can not hold
their remarkable propensity for maintaining straightforward motion are also incapable of
fertilization. Some sperm go forward a
little and then, instead of continuing undaunted, stop and reverse themselves. Such sperm will simply never make it in the
female genital tract.
- Grade III motile sperm are able to
move at a reasonable speed with straightforward progress and accurate homing.
- Grade IV sperm not only advance
straight but do so at an extraordinarily rapid speed. Grade III and Grade IV sperm are sperm capable of fertilization. Grade I and II sperm generally are not.
