ABSTRACT
Recent social science research in the field of parenting following assisted conception has focused on the experiences of donor-assisted conception and surrogacy. This article draws from a study which explored the experiences of the transition to early parenthood in 16 heterosexual non-donor couples and includes a specific consideration of the experiences of men as they navigate this journey. We argue that these couples' transition to early parenthood can be as complex and provisional as in other newer forms of family making as they struggle with an emerging identity as a parent after successful non-donor in vitro fertilisation following their experiences of infertility. Their family making is contingent upon their ability to work at integrating their experiences of infertility and in vitro fertilisation into their emerging identity as a parent. This struggle is prominent when they contemplate a further pregnancy. Considering a sibling causes them further uncertainty and anxiety because it reminds them of their infertile identify and the possibility of further in vitro fertilisation. We report novel findings about the experiences of this transition to parenthood: how couples' identity as parents is shaped by the losses and grief of infertility and the anxiety of in vitro fertilisation. We argue that their struggle with an emerging parenthood identity challenges the normative, naturalised view of non-donor heterosexual in vitro fertilisation parenthood. Our work contributes to the work on identity in parenthood after in vitro fertilisation in an ongoing effort to understand how assisted technologies shape infertile parents' lives. This article reports a small study with a relatively homogeneous sample recruited from one fertility clinic. Nevertheless as an exploratory study of an under researched topic, we discuss useful insights and ideas for further research with larger and more diverse samples.

BACKGROUND: The 156 breeds of dog recognized by the American Kennel Club offer a unique opportunity to map genes important in genetic variation. Each breed features a defining constellation of morphological and behavioral traits, often generated by deliberate crossing of closely related individuals, leading to a high rate of genetic disease in many breeds. Understanding the genetic basis of both phenotypic variation and disease susceptibility in the dog provides new ways in which to dissect the genetics of human health and biology. RESULTS: To facilitate both genetic mapping and cloning efforts, we have constructed an integrated canine genome map that is both dense and accurate. The resulting resource encompasses 4249 markers, and was constructed using the RHDF5000-2 whole genome radiation hybrid panel. The radiation hybrid (RH) map features a density of one marker every 900 Kb and contains 1760 bacterial artificial chromosome clones (BACs) localized to 1423 unique positions, 851 of which have also been mapped by fluorescence in situ hybridization (FISH). The two data sets show excellent concordance. Excluding the Y chromosome, the map features an RH/FISH mapped BAC every 3.5 Mb and an RH mapped BAC-end, on average, every 2 Mb. For 2233 markers, the orthologous human genes have been established, allowing the identification of 79 conserved segments (CS) between the dog and human genomes, dramatically extending the length of most previously described CS. CONCLUSIONS: These results provide a necessary resource for the canine genome mapping community to undertake positional cloning experiments and provide new insights into the comparative canine-human genome maps.
