Testing Sperm Quality
In this article we are going to look at sperm quality tests and some common errors that are being done, and how to avoid them.
Sperm count analysis can help you to determine if you got enough sperm.
But what exactly is enough sperm? A concentration of more than 20,000,000 sperm per ml is enough. If it’s less, then you got a low sperm count, a condition that medical professionals refer to as oligospermia. (oligo is a greek word meaning few).
Another condition that is called azoospermic means heaving no sperm at all, which is true for some unfortunate men. Only a microscopic exam can unmask this condition – otherwise, the problem might not be recognized at all, because the semen look otherwise perfectly standard.
What Is Sperm Motility?
Sperm motility describes how well sperms are moving or how “unwell” they are moving.
The standard of the sperm is usually more serious than the count. There are two kinds of sperm. The ones that swim, and the ones that do not swim.
Guess what the ones that don’t swim are good for? Apparently: nothing. Because in order to fight up their way to the egg of a woman, and be able to fertilize it, an egg needs to be swimming.
Motility is graded from a to d, according to the World Health Organization ( WHO ) Manual criteria, like the following.
- Grade a ( fast progressive ) sperms are those which swim forward fast in a straight line – like led missiles.
- Grade b ( slow progressive ) sperms swim forward, but either in a curved or crooked line, or slowly ( slow linear or non linear motility ).
- Grade c (non-progressive) sperms have moving tails, but they do not change their location (local motility only).
- Grade d ( immotile ) sperms don’t move in the slightest.
Sperms of grade c and d are regarded as poor.
How sperm is shaped also has an impact on it’s quality. Medical professionals refer to this as sperm form or sperm morphology. Ideally, a good sperm should have a regular oval head, with a connecting mid-piece and a long straight tail.
Many laboratories use Kruger “strict “criteria for judging sperm normality. Only sperm which are “perfect” are thought to be standard.
An ordinary sample should have at least 15% standard forms ( meaning even up to 85% unusual forms is thought to be satisfactory. Under the microscope, this is viewed as the sperms sticking together to each other in bunches. This harms sperm motility and forestalls the sperms from swimming up to thru the cervix towards the egg.
What does the presence of pus cells in the semen indicate ?
While some white blood cells in the semen is ordinary, many pus cells suggests the presence of seminal infection.
Sperm Testing Methods
Some laboratories employ a PC to do the semen research. This is named CASA, or PC aided semen research. Even though it may seem to be more trustworthy ( as the test has been done “objectively” by a P. C. ), there are still many controversies about its real worth, since plenty of the technical details haven’t been standardised, and vary from lab to lab.
What does an ordinary semen research report mean ? A standard sperm report is reassuring, and customarily does not have to be repeated. The sole guaranteed way of establishing whether the sperm work is by doing IVF ( in vitro fertilization ).
What are possible explanations for a poor semen research report ?
- too short an interval since the prior ejaculation.
- wrong semen collection method, if the sample isn’t picked up correctly, or if the container is unclean.
- contemporary widespread sickness in the last a quarter ( even an influenza or a fever can temporarily depress sperm counts ).
- too long a delay between providing the sample and its testing in the lab.
Don’t jump to a conclusion primarily based on just one report – remember that sperm counts do have a tendency to vary all alone. It takes 6 weeks for the testes to supply new sperm – and is the reason why you want to wait before repeating the test.
It also makes perfect sense to repeat it from another lab, to make sure that the report is valid.
