NAVARRO MEDINA, P. et al. An analysis of our experience in cryopreservation of semen from cancer patients. Actas Urol Esp [online]. 2010, vol.34, n.1, pp.101-105. ISSN 0210-4806.

Objective: To analyze the characteristics of patients with oncological problems who were users of the sperm bank, as well as use of cryopreserved semen. Materials and methods: A retrospective analysis was made of all cryopreserved semen samples from males diagnosed with cancer from April 1992 to October 2007 at the province of Las Palmas. Results: One hundred and one male patients with cancer were referred to the sperm bank before cancer therapy. Eighty percent of them were contacted by telephone. Mean freezing age was 25 years. Forty-one percent of patients had testicular tumors. Thirty-three percent had no prior biological children. Only one patient had known fertility problems before treatment. Sixty-seven percent of patients were warned by the healthcare team about the possibility of infertility at the time of cancer diagnosis. Only 1% of samples were not adequate for cryopreservation. The frozen sample was used by 4% of the patients. When patients were asked about future use of semen, 63% of them wanted to continue with semen cryopreservation, as compared to 17% who had no interest in having offspring in the future. Conclusion: The number of fertile patients who cryopreserve semen is extremely low. It is very important that the healthcare team warns patients of potential infertility after treatment. A high proportion of patients have valid samples for cryopreservation, but semen is used by a low number of patients. A high proportion of patients want to maintain their semen frozen
