In vitro fertilization with reception of oocytes from partners allows lesbian mothers to share biological motherhood. The gestational mother receives an egg from her partner who becomes the genetic mother. This article examines the ethics of IVF with ROPA with a focus on the welfare of the woman and the resulting child, on whether ROPA qualifies as a “legitimate” medical therapy that falls within the goals of medicine, and on the meaning and value attributed to a biologically shared bond between (...) parents and child. We also contrast IVF with ROPA with egg donor IVF for heterosexual couples and intrafamilial live uterus transplantation with IVF, and show how Swedish legislation makes certain ways of sharing biological bonds out of place. In Sweden, IVF with ROPA is illegal, egg donor IVF for heterosexual couples is allowed and practiced as is sperm donor IVF for lesbians, and live uterus transplantation is performed within a research project. But is ROPA really ethically more problematic than these other cases? The article argues that IVF with ROPA gives rise to fewer ethical questions than does live uterus transplantation with IVF and, in some cases, egg donor IVF. (shrink)
