Project Description

Sperm Analysis & Sample Preparation

The analysis of the semen (sperm diagram) is performed with a microscopic and macroscopic examination.

The most important parameters defined in a sperm diagram are the following:

Volume 2ml and above
pH 7.2 – 7.8
Fluidisation or not within an half hour Yes
Viscosity Normal
Shade of Color The sample must not necessarily have a particular shade of coor
Agglutination A normal sample should not exhibit agglutination. Nevertheless, if agglutination exists at a high percentage (over 50%) then it would be advisable to perform a control of the antibodies
Sperm concentration/ml 20 x 106
Total Sperm concentration/ml 40 x 106
Sperm mobility within an hour >50%
Round cells < 1 x 106
Morphology of the cells (according to Kruger) < 14% normal forms

Some of the terms we use to describe a state of the sample are the following:

  • Oligozoospermia (oligospermia) when the sperm concentration is less than 20 x 106

  • Asthenozoospermia (asthenospermia): when the sperm mobility is less than 50%

  • Teratozoospermia (teratospermia): when the sperm morphology is much lower than 14%

  • Azoospermia: when no sperms can be detected in the sample.

Note: A sperm diagram serves to give us a first impression with regard to the sperm sample. In certain cases, it is necessary to repeat the examination since there is the possibility of having fluctiations to the sample parameters.
