[A father's motherhood... or a mother's fatherhood? Transgender, assisted reproduction and bioethics].

The presence of a transsexual pregnant male in the mass media has made people reassess if transsexuals should have access to assisted reproduction. The bioethical discussion should focus on the future child best interests. This article describes the story of this transsexual man, legally married to a woman in the state of Oregon in the United States. A brief overview of transsexuality and the specific characteristics of this case, with special considerations towards fertility in transsexual people is included. We suggest reflections on what constitutes motherhood and fatherhood and bioethical considerations brought forth by this groundbreaking event.
