In our society, the heterosexual relationship still appears to be the only legitimate form to be a couple or to be a family. However, an increasing number of people who challenge the normative discourse are seeking for same-sex partnerships, often associating these partnerships to the experience of parenting, with biological or adoptive children. The increasing discussions about reproductive and sexual rights and the emergence of new family arrangements, including the one formed by homosexual couples, began to deconstruct the ideal model of nuclear family and its opens up the way for new discussions such as "lesbian motherhood". This study intend to contribute to the homoparenthood debate, by demonstrating the specificities between these women and their ways to construct an intimate citizenship within the context of Brazilian heternormative society. To do so, the following overall aim was: to comprehend the parenthood concepts of lesbian women who seek pregnancy through known or unknown semen donor. The proposed study is based on the assumptions of qualitative research, which means that the subjects discourse was the source of information. Twelve lesbians were interviewed between the years 2009 and 2011. The data were transcribed, organized and analyzed. From the results, it was revealed that the motherhood experience by lesbians depends on several factors such as historical, cultural, social, juridical, legal, economic, public policies, and, of course, the personal history of each of these women. Thus, for women who come out as a lesbian in a heteronormative society and at the same time, opt for motherhood, they have a hard road to face. The solution seems to be to struggle for citizenship and human rights consolidation. So, it's important working up this issue in academic studies and to discuss with other spheres of public policy and social life, including public health.
