Based on in-depth interview data and popular culture texts, the current study has explored the politics of reproduction revolving around women's age in contemporary China. Conceptualizing reproduction as a site of contestation and politics between different, and often contradictory, sets of discourses and power structures, I pursue a feminist and social constructivist analysis of the politics of reproduction in the lives of a group of urban professional women who are yet to enter motherhood at their late 20s and 30s. I engage with Inhorn's (2009) concept of 'disrupted reproduction' to highlight the politically, morally and emotionally charged contestations in the 'problematized' reproductive lives of these women. I unveil how Chinese professional women beyond their 'reproductive prime' are discursively constructed as 'disrupters', who fail their femininity test tied to a motherhood identity within the family context, challenge the 'natural' biological law regulating their reproductive bodies, and face a doomed reproductive future fraught with medical, physical and emotional traumas which ART cannot alleviate. Such a discourse renders invisible the structural causes of problems and challenges professional women face in negotiating parenthood, social norms and selfhood, which systematically put them under pervasive social surveillance and discipline.
