In our fertility clinic, the spermogram is a tool that allows us to evaluate the quality of the semen, and with other medical studies, we can detect which treatment is indicated for each couple. Today you will discover the parameters used for this semen analysis.
First, we invite you to read our article What is a spermogram and how is it done? Once you have read it, we will share with you the six most frequently analyzed sperm parameters:
Sperm concentration is the number of sperm contained in one milliliter of semen. A normal density should be greater than 15 million spermatozoa.
The sperm concentration is very important for fertilizing the oocyte. A lower or higher than normal concentration may indicate a fertility problem. Therefore, it is a fundamental parameter in the spermatozoon.
Mobility is the percentage of spermatozoa in motion and indicates the direction and speed of their movement. Sperm motility is also important, as only motile sperm can travel through the uterus and fertilize the oocyte.
At least 32% of the sperm must be able to move and travel rapidly in a straight line when examined under the microscope. Sperm movement is rated from 0 (immobile) to 4 (optimal motility).
The morphology parameter analyses the size, shape, and appearance of the spermatozoa. We pay attention to the shape of the sperm and its structure since it will be difficult for an abnormal sperm to fertilize the oocyte.
The higher the number of abnormal sperm, the lower the chance of pregnancy. Abnormal shape includes head, neck, and tail abnormalities, as well as immature sperm.
It is a test that involves staining the sperm, which is a method for staining immobile sperm to see if they are alive. It is also called a sperm life test.
There are other cells in semen besides sperm. Leukocytes (white blood cells) are routinely evaluated on a sperm test because they can predict an existing or previous infection.
With this test, particular information can be obtained through the number of leukocytes. Normally, the number of leukocytes should be less than 1 million per milliliter in the semen.
The acid-base balance of the semen is measured by a special paper that changes color. The pH of normal semen gives an alkaline value between 7.2 and 7.8.
The pH value can be affected by problems with one or more glands. The pH value may be affected by problems with one or more glands, although this may not have a significant effect on the potential for infertility in men.
To find out if there is a cause of male infertility, we evaluate each parameter separately and together. Although each factor influences fertility, the analyses may not reflect the true end result. This means that some men with poor semen analysis results may have children, while others with better results may experience difficulties.
