The spermiogram


A spermiogram is a test to determine the quality and quantity of male sperm. The spermiogram is made from a sample of the man’s ejaculate and is used to determine fertility. A spermiogram is often carried out in the context of an unfulfilled desire for a child, in order to look for possible causes.

In order to obtain a reasonable and meaningful result, it is important that the couple does not have sexual intercourse for several days before the semen is released. The spermiogram does not only provide information about the number of sperm in the ejaculate. It also determines the quantity and appearance as well as the viscosity of the ejaculate. The sperms can also be examined more closely with the spermiogram. Here, special attention is paid to the motility of the sperm cells and their appearance.

The indication

A spermiogram is a diagnostic test that provides information about the quality and quantity of the sperm. This test is carried out in the case of an unfulfilled desire to have children, in order to identify any infertility that may exist. This test is also used after vasectomy to assess the success of the procedure.

The procedure of a spermiogram

A spermiogram can be carried out at a urologist or andrologist (sub-area of urology with a focus on fertility and potency) and at a fertility clinic. In order to examine the sperms, they must first be obtained. This is usually done by masturbation.

The practices provide a quiet room for this purpose. Some practices also offer the option of collecting the sample at home. However, strict rules apply here, as sperm are very sensitive and can be damaged prematurely if carried out incorrectly.

The sperm must be collected in a sterile container. This vessel must be transported to the laboratory within one hour. During transport, it is also important to ensure that the vessel is kept at about 37 degrees (body temperature).

In addition to masturbation, sperm can be collected during sexual intercourse using a special condom and used for the examination. In the laboratory, the number, morphology (shape) and motility (mobility) of the sperm is tested. In addition, physical and chemical properties are assessed, such as pH, viscosity and liquefaction time.
