It is a fact that with ageing men’s fertility diminishes. Certain diseases, the medicines taken against these diseases, external environmental impacts, traumas and accidents can cause the diminishment of the men’s fertility, moreover these can cause infertility. Child-planning has been put off, so it can happen that the man’s spermatozoa are no more capable of spontaneous begetting.
It can happen that the sperm of a man having a relationship with a woman is not even usable for artificial insemination, or contains hereditary diseases (for example, haemophilia). In these cases, the use of a donor’s sperm can be a solution for the family. Moreover, nowadays, single women can also use donated sperms for artificial insemination according to some restricted conditions.
