Researchers are developing a fertility preservation technique?testicular tissue cryopreservation (TTCP)?for prepubescent boys who may become infertile as a result of their cancer treatment. Although this technique is still in development, some researchers are calling for its widespread use. They argue that if boys do not bank their tissue now, they will be unable to benefit from any therapies that might be developed in the future. There are, however, risks involved with increasing access to an investigational procedure. This article examines four (...) methods of expanding access to TTCP: (1) expansion of institutional review board (IRB)-approved research trials; (2) offering TTCP as an innovative procedure in hospitals; (3) offering TTCP as a standard practice in hospitals; and (4) commercialization of TTCP. The ethical and practical implications of each are evaluated through a comparison with umbilical cord blood banking (UCBB), a technology that has achieved widespread use based on similar claims of future benefit.

Although analogical reasoning has long been a popular method of reasoning in bioethics, current literature does not sufficiently grasp its variety. We assert that the main shortcoming is the fact that an analogy's value is often judged on the extent of similarity between the source situation and the target situation, while in (bio)ethics, analogies are often used because of certain dissimilarities rather than in spite of them. We make a clear distinction between dissimilarities that aim to reinforce a similar approach (...) in the source situation and the target situation and dissimilarities that aim to undermine or denounce a similar approach. The former kind of dissimilarity offers the analogy more normative force than if there were no dissimilarities present; this is often overlooked by authors who regard all relevant dissimilarities as detrimental to the analogy's strength. Another observation is that an evaluation of the normative force of an analogy cannot be made independently of moral principles or theories. Without these, one cannot select which elements in an analogy are morally relevant nor determine how they should be interpreted. (shrink)

Melanie was 29-years-old, married, and hoping to start a family when she discovered a lump in her pelvis. She was diagnosed with non-Hodgkin lymphoma. But one of her biggest fears upon learning of her diagnosis was the possibility of loosing her ability to have children. When Melanie asked her oncologist and radiation oncologist about the risk cancer treatment posed to her fertility, they told her it was small, as only one ovary would be destroyed during the radiation. Deciding to ask (...) for another opinion, she sought out a reproductive endocrinologist, who told her, contrary to what her oncologists had said, that women like her typically did have problems conceiving after radiation treatment on their pelvis. One of the hardest parts of dealing with her dual diagnosis, Melanie later recalled, was the unknown: “I didn't know if my treatment would definitely render me infertile.”. (shrink)
