OBJECTIVE:To determine the role of male partner involvement in fertility decision-making and intention to use contraceptives by women in four regional states of Ethiopia. METHODS:A mixed-method quantitative-qualitative cross-sectional study was conducted among 2891 women of reproductive age in four emerging regions (Benishangul-Gumuz, Gambela, Afar, and Somali) of Ethiopia. Key informant interview, in-depth interview, and focus group discussion were performed for qualitative data extraction. Simple descriptive statistics were used to analyze quantitative data, and frequency, means, and proportions were used to present the results. Qualitative data were analyzed. RESULTS:Approximately half of the women (1519/2891, 52.5%) discussed contraceptive methods with their partners. Most women did not have the freedom to make independent decisions on fertility preference, with the highest being in the Afar region (376/643, 58.5%). In all regions, the male partner was the dominant decision-maker behind the intention to start using or continue using family planning methods by the woman. Better educational status of male partners and a good attitude towards use of family planning by the woman were associated with contraceptive use by the women. CONCLUSIONS:Male partners play a predominant role in fertility preferences and decisions on family planning use by women.
