Currently, the need to initiate antineoplastic therapies should not mean giving up on motherhood by a patient who has not yet fulfilled her desire to become a mother. In recent years, socioeconomic advances in developed countries have led to a delay in the age at which women begin their search for their first pregnancy. The objective of this paper is to show a detailed review of the scientific literature regarding chemoprophylaxis with GnRH analogues, cryopreservation of ovarian tissue and ovarian stimulation techniques for cryopreservation of oocytes and / or embryos, in patients with oncological pathology, who has not fulfilled their reproductive desires. A literature review was carried out in PubMed, MedLine, Embase, BioMed Central and SciELO databases. Thanks to the improvement of oncological treatments, early detection programs and the appearance of new drugs and therapeutic guidelines, the survival of patients with oncological pathologies has increased. All this has allowed the development of optimal gene therapy for this group of women. The initial assessment of these patients should include the degree of ovarian function impairment that will cause the treatment and its impact on the ovarian reserve. The ovarian reserve is the number of oocytes that the woman has at the time of diagnosis, this decreases exponentially with age, which is a very important factor to take into account.
