The most common way to collect spermatozoa
is through masturbation and ejaculation
, usually on the day of the egg retrieval
Performing "on demand" and being under pressure of time, it is not always easy to produce a semen sample. In such cases, the specimen can be collected at home and dropped off at the IVF Center (the time between ejaculation and handing over the semen sample to the staff of the IVF Center should not exceed 2 hours). On the way to the IVF Center, the specimen should be kept close to your body.
The ejaculate / sperm
has to be produced under hygienic conditions. You should wash your hands and penis thoroughly with soap and then rinse them with a lot of water. To collect the specimen, please ejaculate directly into the precisely labeled sterile container that we have provided you with. Please do not collect your sperm in any other container, because the spermicidal agents contained therein may alter your sperm. In any case, do not use a condom!
Prior to using them for IVF
the sperm is specially processed in the laboratory. Healthy, living sperm cells are separated from the other components of the ejaculate / sperm
This process takes about 1 - 3 hours. Through the processing of semen the following may be achieved:
- Isolation of the best sperm cells
- The density grade of the sperm cells can often be increased
- Sperm cells get activated
- Removal of bacteria and other unwanted components from the ejaculate (e.g. prostaglandins)
