BackgroundAdoption as a treatment option for infertility amongst those that cannot access and/or afford assisted reproduction is not well accepted in developing countries. This study sets out to determine the willingness of infertile women in developing countries to adopt a child and factors that influence women’s attitude to adoption.MethodsWe conducted a questionnaire survey of consecutive infertile patients who attended the gynecological clinic of a regional teaching hospital over a 2-month period. Information on demographics, fertility history, and attitude to adoption was obtained, and the data were analyzed using SPSS version 16.0. Tests of statistical significance were used where appropriate at the 95% confidence level.ResultsThe majority of respondents were aware of child adoption, and the most common source of information was friends (47.8%), followed by the media (39.7%); 42.6% of respondents were willing to adopt if their infertility became intractable. The main reasons given by those unwilling to adopt were culture (78.3%) and family constraints (13.45%). On univariate analysis of factors associated with a favorable or unfavorable attitude to adoption, awareness of adoption (P = 0.002), duration of infertility > 5 years (P = 0.015), no living child (P = 0.007), tertiary education (P < 0.001), pressure from parents (P = 0.041), household yearly income ≥ $650 (P < 0.001), and belief that treatment will bring about the desired results (P < 0.001) were significant, and all except awareness of adoption turned out to be significant on multiple logistic regression analysis.ConclusionThere was a high level of awareness about child adoption among all respondents. However, the acceptability of adoption was significantly lower among poor women and those with limited education. Community advocacy and mobilization, especially through the media as well as via health care providers, will go a long way towards enlightening and enhancing the uptake of adoption among women in Nigeria.
