ObjectiveTo study the association between pre-pregnancy body mass index (BMI) and adverse maternal and neonatal outcomes of singleton pregnancies after assisted reproductive technology (ART).MethodsThis hospital-based retrospective cohort study of women with live singleton births through ART in China from January 2015 to August 2020 included 3043 Chinese women. According to the latest BMI classification standard of Asian women, the women included in this study were classified as underweight (BMI <18.5 kg/m2), normal (BMI 18.5 to <23 kg/m2), overweight (BMI 23 to <27.5 kg/m2), and obese (BMI ≥27.5 kg/m2). We compared the risk of adverse outcomes of different pre-pregnancy BMI values of women with singleton pregnancies conceived through ART. We used Logistic regression analysis to estimate the associations between pre-pregnancy BMI and adverse perinatal and neonatal outcomes.ResultsOur findings showed that women who were overweight or obese before pregnancy through ART are more likely to have a cesarean section, gestational diabetes mellitus, gestational hypertension, and preeclampsia, regardless of whether confounding factors are adjusted. Moreover, pre-pregnancy obesity was more associated with a higher risk of these adverse outcomes than pre-pregnancy overweight. In addition, neonates from women who had obesity before pregnancy through ART were more likely to have macrosomia; adjusted odds ratios and 95% confidence intervals were 3.004 (1.693-5.330).ConclusionsOur research showed that women who had pre-pregnancy overweight or obesity with singleton pregnancies through ART were more likely to have a cesarean section, gestational diabetes mellitus, gestational hypertension, and preeclampsia. Moreover, neonates from women who had obesity before pregnancy were more likely to have macrosomia.

Background: Pregnancy through assisted reproductive technology (ART) is a stressful experience that may affect prenatal attachment. However, maternal-fetal attachment (MFA) and anxiety in pregnancy after ART are understudied in Iran. Objective: To compare changes in MFA and pregnancy-related anxiety (PRA) in the first and third trimester of pregnancy in women who conceived through ART compared to those who conceived naturally. Materials and Methods: This longitudinal study was conducted in 2019 with 187 pregnant women (ART conception = 43, natural conception = 144). Participants were recruited using the consecutive sampling method from a prenatal clinic in Tehran. The Cranley MFA Scale and the Van Den Bergh PRA Questionnaire were used to collect the data. Results: The MFA score in the 12th wk of gestation was lower in the women who conceived with ART compared to in the women who conceived naturally, but there was no statistically significant difference between the groups in wk 36. MFA in both groups was significantly higher at gestational wk 36 than wk 12 (p ≤ 0.001). The increase in MFA score was significantly higher in the women who conceived with ART than in those who conceived naturally (p ≤ 0.001). The anxiety score declined in the two groups and no statistically significant difference was observed in the changes of anxiety scores between the two groups (p = 0.84). Conclusion: Pregnant women who conceived through ART were as attached to their fetus in the third trimester of pregnancy as other women and did not experience more PRA. Key words: Attachment, Maternal fetal relations, Assisted reproductive technology, Pregnancy, Anxiety.

Since the mid-2000s, a number of Western countries have witnessed an increase in the number of children born into ‘alternative’ or ‘queer’ families. Parallel with this queer baby boom, online media technologies have become intertwined with most people’s intimate lives. While these two phenomena have appeared simultaneously, their integration has seldom been explored. In an attempt to fill this gap, the present article explores the ways in which contemporary queer reproduction is interwoven with online media practices. Importantly, the article does not understand online media as a technology that simply facilitates queer kinship; rather, it argues that online media technology is a reproductive technology in its own right. Drawing on empirical examples of media practices of kinning, such as online shopping for donor sperm and locating ‘donor siblings’ via online fora such as Facebook, the article analyses the merging and intersection of online media and queer kinship. These analyses serve as a foundation for an exploration of contemporary kinship and the development of a new theoretical framework for contemporary queer reproduction. Empirically, the examples are from single women’s (i.e. solo mothers) and lesbian couples’ family making. Using Weston's work on ‘chosen families’ as a backdrop for discussion, the article describes families of choice in light of new online kinship connections. In particular, the article focuses on online-initiated connections between donor siblings and how such connections can re-inscribe biology as important to queer kinship. Furthermore, it closely examines how media technology guides queer reproduction in particular directions and how technology causes becoming as a family.

This article uses data gathered from a study conducted in Portugal to examine the (plural and composite) conceptions that doctors, embryologists, and beneficiaries of Assisted Reproductive Technology (ART) have of the in vitro human embryo. Taking the sociology of engagements, developed by Thévenot, as its theoretical lens, the article draws on a total of 69 interviews with ART patients to analyse the plurality of fluid meanings produced about this biological entity, whose status is neither static nor universal. ART beneficiaries are likely to produce plural conceptions of the lab-generated embryo within the framework of different regimes of engagement, understood as cognitive and evaluative formats. These various pragmatic regimes, in turn, entail distinct emotional investments. When speaking about their relationship with embryos, beneficiaries therefore express plural emotional experiences, which are articulated using terms such as affection, love, detachment, loss, frustration, hope, mourning, and anguish. Using the theoretical framework of the sociology of engagements, we propose an approach that enables us to produce a detailed record of the connections between the cognitive, evaluative, and emotional dimensions in beneficiaries’ relationship with—and decision-making processes about—the embryos, accounting for the plasticity of emotional states linked to the (re)configuration of attributed meanings.
