Examining the lack of data about the method in the study area regarding married men's knowledge and attitudes toward vasectomy.
A married man between the ages of 31 and 40 is 2.3 times more likely to have good knowledge than a man between the ages of 21 and 30. [17](#cit0017) It might be due to the increase in awareness and information with age. Age, educational status, and completed family size were found to have a significant relationship with knowledge of vasectomy among married men in Arba Minch town. The proportion of men who respond to the attitude question, more than one hundred thirty nine (62.9%) of the respondents disagreed on the involvement of men in family planning. The majority of participants in the study (363, or 74.2%) had not discussed family planning with their wives ( About 221 (36.8%) of married men reported that they had ever heard about vasectomy. Section I was designed to collect data on socio-demographic characteristics, Section II was designed to collect questions about reproductive health, Section III was designed to collect information about knowledge of vasectomy, and values of 1 and 0 were given for each correct and incorrect answer, respectively, and Section IV was designed to collect information about attitude toward vasectomy using a likert categorization method (agree, neutral, disagree). [9](#cit0009), [10](#cit0010) In Gondar, more than two-thirds (70.2%) of the respondents were not aware of vasectomy as a form of male family planning method. [6](#cit0006) In Nigeria, only 13.2% had high knowledge about vasectomy, and most of them showed a negative attitude towards vasectomy and assumed that vasectomy should not be done by men and that females should be responsible for family planning but the decision on the method to use should be demanded from them as the head of the family. Respondents were considered to have good knowledge if they scored 60% or above (a respondent who answered six or more of the knowledge questions was considered to have good knowledge). Men’s knowledge of vasectomy was significantly associated with college or university attendance (AOR = 4.05, 95% CI: 1.720– 9.521), age 31– 40 years (AOR = 2.308, 95% CI: 1.081– 4.929), and age ≥ 41 years (AOR = 2.671, 95% CI: 1.159– 6.156). Age ≥ 41 years (AOR=4.735 95% CI 2.015– 11.129), age of last child (AOR=3.868 CI 1.554– 9.632) and discussing family planning with wife (AOR=2.821 95% CI 1.559– 5.105) were significantly associated with attitude of men towards vasectomy.
