In some cases, there might not be any sperm cells in the male semen. In such cases sperm is retrieved from the testis by inserting a needle into the testis and aspirating (TESA - Testicular sperm aspiration) or by a testicular biopsy of the testis (TESE-Testicular sperm extraction). Sperm retrieved, then, fertilizes the egg and pregnancy may be possible. However, in cases where sperm cannot be retrieved from the testis, "Sperm Donation" might be an available solution.
In these types of occasions, ready products, which are collected, examined and scanned for number, movement and abnormal morphology, and then, seen fit for storing at certain centres in the world are used. Institutions dealing with such procedures are called sperm banks. Sperms are stored by freezing them. Just as in the case of egg donors serology tests are done (HIV, hepatitis B, C). Mostly, donations stored in England, Denmark and the USA are used. Our centre co-operates with the Danish origin Cryos Sperm Bank.
In sperm donation treatments the first step is to stimulate the folicules of the female. Medication used is the same medication used for classical IVF treatment. Usually on the second day of the menstrual cycle, after the specialist's examination injections will be started and approximately in 10-14 days eggs become mature enough to be collected. The time span depends on the structure of the ovary. Egg collection, fertilization and embryo transfer are processed at our centre. There are about three days between egg collection and transfer. This might also be possible in five days.
