Abstract：
Preimplantation genetic diagnosis (PGD) has been used not only to avoid genetic diseases and increase conception success rates but also to perform non-medical sex selection, particularly in the surging cross-border reproductive care (CBRC). In the context of commercialised biomedicine, assisted reproductive technologies, such as lifestyle sex selection, have been tailored to meet intended parents\' preferences. However, there is a lack of analysis on how individuals\' reproductive decisions on PGD-assisted sex selection were shaped within the sociocultural norms and CBRC. This article explores Taiwanese gay fathers\' navigations on sex selection while seeking third-party reproduction overseas because of local legal constraints. Drawing on in-depth interviews with 53 gay fathers (to-be), I analysed how \'individual preferences\' were dynamically shaped by local sociocultural norms and embedded within transnational settings of routinising PGD in chosen repro-destinations. The findings showed that gay fathers mobilised strategic discourses on non-medical sex selection from both the local and the global to negotiate their decisions in coherence with their LGBTQ+ identity and their role as sons carrying familial responsibility to procreate male heirs. This article proposed a nuanced understanding of gay fathers\' reproductive practices of \'gendering the beginning of life\' through PGD-assisted sex selection.
摘要：
植入前遗传学诊断（PGD）不仅用于避免遗传疾病和提高受孕成功率，而且还用于进行非医学性别选择。特别是在激增的跨境生殖保健(CBRC)中。在商业化生物医学的背景下，辅助生殖技术,比如生活方式的性别选择，已经量身定做，以满足预期的父母的喜好。然而,在社会文化规范和银监会范围内，缺乏对个人关于PGD辅助性别选择的生殖决策的分析。本文探讨了由于当地法律限制，台湾同性恋父亲在海外寻求第三方生殖时对性别选择的导航。通过对53名同性恋父亲（准）的深入采访，我分析了“个人偏好”如何由当地社会文化规范动态地塑造，并嵌入在选定的目的地中对PGD进行常规化的跨国环境中。调查结果表明，同性恋父亲从本地和全球动员了有关非医学性别选择的战略话语，以与他们的LGBTQ身份以及他们作为承担家庭责任以生育男性继承人的儿子的角色保持一致的决定。本文通过PGD辅助的性别选择，提出了对同性恋父亲的“生殖实践”的细微理解。
