A semen analysis at the Kinderwunsch Institut Dr Loimer in Linz provides information about a man’s fertility and the quality of sperm. As part of the investigations of the couple, this is the most important finding for men.

A sample only shows us the current state of the sperm. Since the results can vary greatly also in normally fertile men, another semen analysis is always necessary after two to three months. With this we can then see in which ‘direction’ the semen quality is heading. Often a physical examination by a urologist is also necessary. If medication is taken regularly, the Dr must be informed before the sample is given.

A waiting period (no sexual intercourse) of two to five days should be observed before submitting a semen sample. The sample can be provided in a discreet room at the Kinderwunsch Institut Dr Loimer and is then immediately assessed in the laboratory. As a rule, you will receive a written report about 20 minutes later, which will be explained to you in detail.

If the semen sample is produced at home, it must be brought to the Kinderwunsch Institut Dr Loimer in the shortest possible time (max. 30 minutes) in order that the quality does not suffer.

The following parameters are taken into account when evaluating semen quality:

  • Volume of the sample (at least 1.5 millilitres)
  • Number of sperm cells per millilitre (density)
  • Mobility of the sperm cells (motility)
  • Shape of the sperm cells (morphology)


Additionally, the pH value, fructose value, viscosity and possible bacterial colonisation in the seminal fluid are determined during the semen analysis. In the case of very limited semen quality, genetic testing can also be useful, as certain genetic diseases lead to changes in semen quality.

MAR Test (Mixed Antiglobulin Reaction Test) at the Kinderwunsch Institut Dr Loimer Linz
This test looks for sperm autoantibodies in the ejaculate. Autoantibodies arise when the vas deferens are internally injured. Under normal conditions, the sperm swim through the mucus of the female cervix into the uterus. However, autoantibodies bind to the sperm and prevent their migration. In order for natural pregnancy to occur, no more than half of all sperm must be blocked with autoantibodies.
