Ready to know more...sperm head.

,,,,,,,,,, Type "a" .......hahaha piraty -lah...party of loyal to none!! ...survival of the fittest yaa,,,,,,,,we made it !! yooohohoo. ....hey matey survivors .....yaaaaaaaaa had been, still is a battle ??....make it fun as always, if NOT why NOT ?.......'allsome' hehehe !

The anatomy of a sperm !!....Yoo

,,,Do you know, if there are enough sperms from yours ??. If the sample has less than 20 million sperm per ml, this is considered to be a low sperm count. Less than 10 million is very low. The technical term for this is oligospermia (oligo means few).

,,, Some men will have no sperms at all and are said to be azoospermic. ,,,Yaaa !!....This can come as a rude shock because the semen in these patients look absolutely normal - it is only on microscopic examination that the problem is detected.
,,,Whether the sperms are moving well or not (sperm motility). The
quality of the sperm is often more significant than the count. Sperm
motility is the ability to move.

,,,Sperm are of 2 types – those which swim like mine, and those which don’t like yours ?. hehehe,,,just joking ya!!

,,, Oooh,,, Yes b4 I forget-lah!!...Remember that only those sperm which move forward fast are able to swim up to the egg and fertilise it – the others are of little use.

,,,Motility is graded from "a to d", according to the World Health Organisation ( WHO) Manual criteria , if I can remember correctly lah, as follows ; -

...Grade a ( fast progressive) sperms are those which swim forward fast
in a straight line - like guided missiles from pirate ship.

...Grade b ( slow progressive) sperms swim forward, but either in a curved or crooked line, or slowly (slow linear or non linear motility) ...as from most politicians'..... haaaha !!

...Grade c ( nonprogressive) sperms move their tails, but do not move forward ( local motility only). ...like most locals ??.

...Grade d ( immotile ) sperms do not move at all . ..cool guys koy ??.

,,,Hahaha,,,,,Please note that sperms of grade c and d are considered poor.

,,,BUT, why do we worry about poor motility ? Well, if motility is poor, this suggests that the testis is producing poor quality sperm and is not functioning properly – and this may mean that even the apparently motile sperm may not be able to fertilise the egg.

,,,Whether the sperms are normally shaped or not - what is called their
form or morphology. Ideally, a good sperm should have a regular oval
head, with a connecting mid-piece and a long straight tail. If too
many sperms are abnormally shaped (round heads; pin heads; very large heads; double heads; absent tails) this may mean the sperm are
abnormal and will not be able to fertilise the egg.

,,,Many labs use Kruger "strict " criteria ( developed in South Africa ) for judging sperm normality. Only sperm which are "perfect" like mine !!,,hohohoo are considered to be normal. A normal sample should have at least 15% normal forms ( which means even upto 85% abnormal forms is considered to be acceptable !)

,,,Sperm clumping or agglutination. Under the microscope, this is seen as the sperms sticking together to one another in bunches. This impairs
sperm motility and prevents the sperms from swimming upto through the cervix towards the egg.

,,,Putting it all together, one looks for the total number of "good"
sperms in the sample - the product of the total count, the progressively motile sperm and the normally shaped sperm. This gives
the progressively motile normal sperm count which is a crude index of
the fertility potential of the sperm.

,,,Thus, for example, if a man has a total count of 40 million sperm per ml; of which 40% are progressively motile; and 60% are normally shaped; then his progressively motile normal sperm count is : 40 X 0.40 X 0.60 = 9.6 million sperm per ml. If the volume of the ejaculate is 3 ml, then the total motile sperm count in the entire sample is 9.6 X 3 = 28.8
million sperm.

,,,O.K. got it guys/plus you ladies should be aware of too !!

,,,Yooo........hahaha !!......chopper pilots normally get daughters, will tell you why later o.k.??.....(hover too long-lah)
