ABSTRACT In Denmark, female patients who undergo chemo- and radiation therapy are, prior to treatment, increasingly offered fertility preservation in the form of ovarian tissue freezing. In the cryotank, the frozen ovarian tissue awaits the recovery of the patient, after which it can be thawed and implanted into the remaining ovary or the abdominal wall. Here it potentially restores the ovarian function and enables women to become pregnant and experience genetic motherhood. Promising reproductive futures, the biomedical imaginary of ovarian tissue preservation is entangled with visions of possibilities and risk management as well as gendered understandings of reproduction and the ‘good life.’ From the get-go, ovarian tissue freezing has been informed by an optimistic imaginary of scientific progress. Not only were freezing programs established before clinical evidence testified to the success of the technique in humans; the envisioning of improvements and new applications also anticipates future scientific breakthroughs, such as in vitro maturation of eggs. In the imaginary of hopefulness and reproductive futurity, frozen ovarian tissue becomes an object of vitality which (re)installs the cancer patient as a reproductive citizen. Moreover, ovarian tissue is imagined as a bountiful material with different potentiality than egg freezing. In Denmark, the biomedical imaginary romanticizes the restoration of ‘natural’ fertility and spontaneous pregnancies. Thus, the potentiality of ovarian tissue freezing is imagined within a normative framework privileging ‘natural’ conception, yet simultaneously destabilizing the very notion of the age-span of ‘natural fertility.’

冷冻中的希望与幸福的未来：卵巢组织冷冻的生物医学想象

摘要在丹麦，接受化学和放射疗法治疗的女性患者在治疗前以卵巢组织冷冻的形式越来越多地提供生育能力保护。在冷冻箱中，冷冻的卵巢组织等待患者康复，然后可以将其解冻并植入剩余的卵巢或腹壁。在这里，它有可能恢复卵巢功能，并使妇女能够怀孕并经历遗传性孕育。卵巢组织保存的生物医学假想有前途的生殖前景，充满了对可能性和风险管理的愿景以及对生殖和“美好生活”的性别理解。从一开始，对卵巢组织的冷冻就被科学发展的乐观想象所告知。在临床证据证明该技术在人类中取得成功之前，不仅建立了冷冻程序，而且还建立了冷冻程序。改进和新应用的设想也预见了未来的科学突破，例如卵的体外成熟。在有希望和生殖未来的想象中，冷冻的卵巢组织成为生命的对象，这（重新）使癌症患者成为生殖公民。此外，人们认为卵巢组织是一种具有丰富潜力的物质，其潜力与冷冻卵子不同。在丹麦，生物医学的想象使浪漫恢复了“自然”的生育能力和自然怀孕。因此，可以在赋予“自然”概念的规范框架内想象卵巢组织冻结的可能性，
