There are numerous states, pathologicalas well as some other, for which particular person or couple haveendangered reproductive function, before he or she has managed to achieve in the role of parents. Unfortunately, in recent decades there was an increased prevalence of numerous malignant diseases affecting women and men in an earlier age during the reproductive period. Optimistic is the fact that most of malignant diseases (including the most common breast cancer, lymphoma, leukemia, cervical cancer, and many others) are successfully treated today if the disease is detected at an early stage, but it will, as a result of the disease or its treatment and use of chemotherapy, reproductive function in most cases be seriously affected, if not impossible. On the other hand, the contemporary cultural and social trends often lead to postponement of achieving the parenthood to a later age. It should be borne in mind that the biological clock was not created after the agenda of such plans. In addition, there are a number of non-malignant diseases such as endometriosis, benign ovarian tumors and its surgical treatment, as well as genetically conditioned premature exhaustion of ovarian function, which can lead to significant loss of reproductive function at very young age prior to realization of parenthood. Severe damage to spermatogenesis in men, of known or unknown origin, as a result of inflammation, tumors, trauma, and many other factors (often of unknown cause), also tends to deteriorate and lead to a loss of reproductive function prior to realization of parenthood. In all these situations, modern medicine has brought to perfection techniques of fertility preservation by improvement of freezing - cryopreservation of ova, ovarian tissue, sperm, and embryos and the use of modern methods of vitrification. Nowadays this is a standard in approaching a person with these problems, and is considered unacceptable that someone is not informed or was not given an opportunity to preserve fertility in situations when faced with potential endangerment of reproductive function.
