Abstract
Introduction
While largely preventable, cervical cancer remains a major cause of morbidity and mortality in low- and middle-income countries (LMICs), where gaps in screening uptake persist despite expanding prevention efforts. In many patriarchal settings, men play influential roles in household decision-making and access to healthcare, positioning them as critical but under-engaged stakeholders. There remains limited understanding of how educational strategies to improve health literacy can be designed to effectively engage men in supporting women’s screening participation.
Methods
We conducted a qualitative study in northern Ghana to explore men’s understanding, priorities, and values related to cervical cancer prevention to inform male-focused educational strategies. Guided by the Consolidated Framework for Implementation Research and the Health Belief Model, 9 in-depth semi-structured interviews were conducted with married adult men recruited from community settings, examining household roles, perceptions of cervical cancer and screening, and preferences for education and engagement approaches. Interviews were conducted in English or Dagbani, audio-recorded, transcribed, and analyzed thematically using a hybrid inductive and deductive approach.
Results
Three cross-cutting themes emerged. Men viewed healthcare professionals as trusted sources of cervical cancer information and described their roles as primary financial decision-makers, with cost and competing household priorities influencing support for screening. Masculine responsibility, particularly related to fertility and family wellbeing, strongly motivated engagement, and messages framed around these themes were more compelling than disease-focused messaging alone. Participants recommended integrating education into routine health services, leveraging healthcare workers, offsetting screening-related costs, and using mass media to initiate awareness and information seeking.
Conclusion
Men represent pivotal yet underutilized partners in cervical cancer prevention. Educational strategies that align with men’s roles, economic realities, and trusted sources of information and address household decision-making barriers may enhance screening uptake while supporting women-centered care. These findings provide implementation-relevant insights to inform male-engaged cervical cancer prevention strategies across diverse LMIC settings.

Introduction
Cervical cancer, though largely preventable and curable, remains a major global health challenge, with the highest incidence and mortality concentrated in low- and middle-income countries (LMICs).1-3 Particularly, Africa experiences the highest incidence and mortality rates worldwide, reflecting persistent gaps in prevention, early detection, and treatment.4-7 Part of the World Health Organization’s strategy to eliminate cervical cancer includes ensuring that 70% of women are screened at least twice in their reproductive-aged years, specifically by age 35 and again by age 45. 5 Improving health literacy, defined as the ability to access, understand, and act on health information, has been identified as a key strategy for increasing screening uptake and reducing disparities in cancer prevention.8-10 In many African contexts, health literacy efforts are often delivered through community-based approaches that account for local cultural norms and social structures. Despite the expansion of screening program across many African countries, screening uptake remains suboptimal due to limited awareness, sociocultural perceptions surrounding screening, and gendered dynamics that shape women’s access to healthcare, particularly in patriarchal contexts where men often influence or control health-related decision-making.11-15
Emerging evidence indicates that engaging men as active partners in cervical cancer prevention may be an effective strategy to increase screening uptake and reduce the overall burden of cervical cancer.16-20 Men frequently play a central role in household decision-making related to healthcare utilization and resource allocation, positioning them as key stakeholders in women’s access to preventive cancer services. Studies indicate that when men are informed about cervical cancer and the benefits of screening, they may be more likely to provide emotional, logistical, and financial support for screening and follow-up care, as well as help reduce stigma and misconceptions surrounding cervical cancer.21-23 The potential value of male engagement in cervical cancer prevention is further supported by evidence from other sexual and reproductive health interventions, including prenatal care and prevention of mother-to-child human immunodeficiency virus (HIV) transmission, where male involvement has been associated with improved health outcomes.24-26
Specifically education has emerged as a key strategy for engaging men in cervical cancer prevention efforts, by increasing health literacy, knowledge, addressing misconceptions, and fostering supportive behaviors related to women’s screening participation.16,27,28 However, substantial gaps remain in understanding how men interpret cervical cancer information, which messages resonate most strongly, and how educational approaches can be designed to align with men’s priorities, values, and decision-making roles.11,29 Ghana, particularly its northern region, offers a valuable context for addressing these questions, as it reflects a predominantly patriarchal social structure in which men play a central role in household and healthcare decision-making, mirroring broader gender dynamics across many African and similar low- and middle-income settings.30-33 The disparity between health literacy and screening practice is also found to be wider in northern Ghana than its southern counterparts, requiring nuanced attention to traditional values and priorities.34-36 In such contexts, the effectiveness of male-focused education depends not only on increasing awareness, but on how information is framed and delivered in ways that align with men’s roles within the family. Examining men’s perspectives in northern Ghana therefore provides an opportunity to generate contextually grounded insights into how educational strategies for men can be designed to meaningfully support women’s cervical cancer screening uptake and inform similar efforts in other settings shaped by comparable gender norms.
Accordingly, we conducted a qualitative study to explore how men in northern Ghana understand cervical cancer prevention, what motivates their support for screening, and how educational messages can be tailored to resonate with their roles and responsibilities, with the goal of informing the development of a community-driven educational intervention targeted to men.
Methods
Study Context and Implementation Setting
Cervical cancer remains a major public health challenge in Ghana, where it is the second most common cancer among women, with an estimated 3,072 new cases and 1,815 deaths reported annually.1,4 This corresponds to an age-standardized incidence rate of 27 per 100,000 women and a mortality rate of 16.9 per 100,000, highlighting the substantial risk faced by the country’s 10.6 million women susceptible to the disease. Ghana currently lacks a coordinated national cervical cancer screening program, with formal screening guidelines limited primarily to women living with HIV/AIDS.37,38 As a result, cervical cancer prevention efforts are largely implemented through regional and facility-level initiatives, even as there is increasing national momentum to expand prevention through broader screening access and the introduction of school-based human papillomavirus (HPV) vaccination programs.37,39,40
Northern Ghana is a region where cervical cancer prevention challenges are particularly acute due to socioeconomic disadvantage, limited health infrastructure, and reduced access to healthcare services (34). 41 The study was embedded within regional cervical cancer prevention efforts supported by AMPATH Ghana (Academic Model Providing Access to Healthcare), a global health academic partnership between NYU Grossman School of Medicine (USA), the University for Development Studies (Ghana), and Tamale Teaching Hospital (Ghana), in collaboration with the Ghana Health Service. This partnership provided the programmatic infrastructure and community engagement context within which the present qualitative study was conducted. 42
Study Design
This qualitative study was guided by the Consolidated Framework for Implementation Research (CFIR) to examine multilevel determinants of cervical cancer prevention, and by the Health Belief Model (HBM) to address individual health behaviors and decision-making.43-45 The CFIR provided a systematic approach to understanding the implementation context, while HBM informed the exploration of perceptions, knowledge, and attitudes related to cervical cancer prevention and screening behaviors.
Study Population, Sampling, and Recruitment
The study population consisted of adult men residing in the Tamale Metropolitan Area in northern Ghana. Eligible participants were required to be 18 years of age or older, able to communicate in either English or Dagbani, and able to provide verbal informed consent. A community-based purposive sampling approach was used to recruit participants face-to-face from key social and occupational settings across the metropolitan area, including workplaces, marketplaces, and other common community gathering spaces. Random, in-person recruitment was conducted within these settings, with study team members approaching eligible men and inviting them to participate. Rates of declining participation among approached men in the local metropolitan area were not recorded. Participants were compensated for their time. Recruitment continued until thematic saturation was achieved, which occurred after nine interviews (n = 9). Thematic saturation was defined as the point at which new data gathered would not contribute significantly to addressing the research question and existing data was being replicated. 46 This sample size approach is consistent with prior literature investigating appropriate sample sizes and thematic saturation for qualitative studies. 47
Study Tool
Using CFIR and HBM as guiding frameworks, a semi-structured interview guide was developed to assess participants’ roles within their families and communities, baseline knowledge and perceptions of women’s health issues (including cervical cancer), and attitudes towards potential interventions to increase screening uptake. Specific, targeted questions at the end of the interview aimed to understand how men envisioned their involvement in cervical cancer prevention efforts. The guide was developed in English, translated into Dagbani, the predominant language in this part of Ghana by a research team member, and pilot tested in both languages. Following three iterative revisions based on feedback from these pilots, trained research assistants in English and Dagbani administered the finalized guide to participants.
Data Collection
Two authors conducted the semi-structured interviews: MC (female medical student from the United States at NYU Grossman School of Medicine) and CT (male registered nurse from northern Ghana at Tamale Teaching Hospital). Both interviewers had prior research training and experience. Prior to data collection, they participated in three qualitative research training meetings with SH, the study Principal Investigator (PI), who has extensive experience in qualitative research. They also conducted three supervised practice interviews, which were reviewed by the study PI to provide feedback and ensure consistency and quality in the interviewing approach.
Interviews were conducted at locations chosen by participants where privacy could be ensured. Most interviews took place at participants’ workplaces, market centers, or mosques, and only the participant and the interviewer were present. Interviews were conducted in either English or Dagbani and were audio-recorded to ensure accuracy. Rapport was established during recruitment and when scheduling the interview, at which time participants were provided with a brief description of the study aims and interview process. Participants were aware of the interviewers’ professional roles in the study, although no additional information about the interviewers’ personal backgrounds or perspectives on the research topic was disclosed.
Interviews lasted approximately 45 minutes on average, and repeat interviews were not conducted. Interviews conducted in Dagbani were translated and transcribed into English for analysis. Translation was completed by study team member fluent in both English and Dagbani (CT), to ensure preservation of meaning. Transcripts were not returned to participants for review or correction following transcription and translation. Field notes were not collected as part of this study. To ensure data quality, the study PI reviewed the first three interviews and transcripts. Thematic saturation, indicating sufficient depth and breadth of data, was achieved early in the study and finalized after completing nine interviews (n = 9).46,47
Data Analysis
Prior to any data analysis, transcripts were de-identified and all details that could have suggested a participant’s identity were removed. Transcripts were stored in a secure cloud location for access by approved study team members as per IRB guidelines. A preliminary codebook was developed using a hybrid deductive and inductive approach, informed by both CFIR and HBM frameworks, as well as an initial inductive review of the interview data and finalized collaboratively between three team members (NK, CH, AA) through two iterative rounds of refinement. Codes were then grouped into higher-order categories based on conceptual similarity, with primary categories of participant roles, values and priorities, involvement in wife’s healthcare, resources, engagement with sexual and reproductive health, and strategies for screening programs and implementation (Appendix A). Three study team members (NK, CH, AA) participated in the coding of each transcript, and each transcript was coded independently by two team members in Dedoose (Version 9.2.22, SocioCultural Research Consultants, LLC, Los Angeles, CA, https://doi.org/www.dedoose.com). Coding discrepancies were systematically resolved through discussion, and a final agreed-upon code was applied. Synthesizing the resulting codes into comprehensive themes was completed both via a deductive and inductive thematic analysis approach led by two team members and supervised and finalized by study PI to ensure consistency and rigor in the thematic analysis. Study participants were not contacted after thematic analysis to provide feedback on the findings for the present study; however, member-checking procedures are planned in future work.

Results
Participant Demographic Characteristics (N = 9)
Three major themes emerged from the data describing how men perceive and engage with cervical cancer prevention in northern Ghana. These included (1) trust in healthcare professionals as credible sources of information, (2) the influence of financial decision-making on health prioritization, and (3) the role of masculine responsibility and fertility in shaping support for screening. Figure 1 represents a thematic A thematic map is included to represent of our main themes and findings. A visual summary of the main study themes
Trust in Healthcare Professionals as Gateways to Knowledge
In this population of men, there was an existing high level of trust in the healthcare system and its providers. Because of this, men were highly receptive to education about cervical cancer prevention from healthcare professionals and placed high value on medical advice. Participants consistently described deferring to healthcare workers when making decisions about their wives’ care, emphasizing that their first action when a spouse was ill was to encourage or empower her to seek medical attention by a trusted healthcare worker. “I always advise her that the going to hospital to seek healthcare is good, and she is supposed to be going to the hospital, anytime whatever the doctors tell or advise her on it good to follow it.” (57 years old, married with children, occupation tailor)
Participants expressed a desire to learn about cervical cancer and screening from healthcare professionals, as the credibility and ethos of the provider conferred a greater degree of trust and factual weight. Much of men’s prior knowledge of women’s health came through their interactions with healthcare workers during their wives’ antenatal care. “I wanted to learn about it from a health worker who has much knowledge about the cervical cancer… I will have been happy if a doctor will speak with me on one-on-one face-to-face.” (57 years old, married with children, occupation tailor)
While men preferred that female providers attend to their wives, they acknowledged that this was not always possible and prioritized access to care over provider gender. “It is not something that she is doing willingly...it is because she needs to be looked at, it is about her health, it's not about her nudity or any other thing…so I am not worried about that.” (64 years old, married with children, unit community leader)
Financial Decision-Making and the Tension Between Support and Scarcity
Participants described themselves as primary financial, ideological, and emotional providers within the household and as key decision-makers regarding resource allocation. They expressed a strong desire to fund their wives’ healthcare and to act in their best interest when they fall ill. However, limited financial means and competing priorities created tension between their desire to provide care and ability to do so. “In the case that your business is not booming and you don't have money, and your wife is sick, you will see that you have to be sending her to private hospitals so that is why I wished that I had more resources so that when my wife is sick, I can be able to send them to any hospital at all.” (39 years old, married with children, occupation independent businessman) “I support her financially, but here in Africa it’s not every day you make money. Some days you work and earn something, other days you don’t. If she needs money for healthcare when I don’t have it, I have to borrow so she can go.” (57 years old, married with children, tailor)
Because of these financial pressures, preventive services such as cervical cancer screening are often deprioritized in favor of more immediate or acute concerns. “Because of the cost payment involved that is why majority don't do screening… Some men really want their wives to go for the screening but they don't have money to give them to pay for it.” (57 years old, married with children, occupation tailor) “Here, we don’t go to the hospital until we feel uncomfortable. That one is true. We don’t plan it. Until you are sick, and even the sickness has a level to reach before we go to the hospital.” (65 years old, married with children, occupation public servant)
Cervical cancer screening was perceived as taking financial precedent only when men understood it as directly relevant to urgent family health needs, such as antenatal care or fertility. “The disease I am likely to fund is infertility. That is, if a woman cannot give birth… so I mean literally that she can be in the childbearing age, but she won’t be able to conceive ... That is the disease that I would be more likely to fund.” (39 years old, married with children, occupation businessman)
Masculine Responsibility, Fertility, and Family as Drivers of Engagement in Healthcare
Men’s engagement in women’s healthcare was deeply tied to their self-perceived responsibilities as heads of household, emotional partners, and fathers. Participants articulated a strong sense of duty to ensure the health and stability of their families, roles that extended beyond financial provision to moral and emotional support. “I support her in finance, first. And second, I support her in terms of advice on what she should do or what she should not do. And sometimes, the support, I go together with her to the healthcare facility... I think that I support her, financially and morally.” (64 years old, married with children, unit community leader)
Men described their wives as both loved partners and essential contributors to the family’s wellbeing, particularly through childbearing and caregiving. Their investment in women’s health stemmed from two intertwined motivations: affection and familial responsibility. For many, supporting their wives’ health was viewed as an extension of caring for their children and sustaining the family line. “Whenever she’s not feeling well and she’s looking very sad, I also feel very sad. I’m not happy, even if I go out, I don’t normally interact with my friends and they ask me why, why are you so cold today? I say my wife is not feeling well and she’s not happy. And I am also not happy.” (64 years old, married with children, unit community leader) “I’m so motivated. Because, my wife’s healthcare is my healthcare, so I should be concerned about it. If she goes away, who will take care of my children for me?” (41 years old, married with children, occupation bank manager)
Fertility and family-building consistently emerged as central motivators for men’s support of cervical cancer screening. Participants linked the disease to infertility and pregnancy complications, recognizing that undiagnosed cervical cancer could threaten both family growth and stability. Once men understood this connection, their willingness to support their wives, both financially and emotionally, increased substantially. “Oh, now that I know that [cervical cancer screening] is important as far as production of children is concerned, I will increase it, to support her to get me good healthy children.” (65 years old, married with children, occupation public servant) “It could be that is the reason why my wife is not able to get pregnant again.” (57 years old, married with children, occupation tailor)
At baseline, men’s knowledge of cervical cancer was limited, with most awareness derived from prior experiences with antenatal care or infectious disease programs. However, when educational messages resonated with men’s existing priorities, family health, fertility, and family harmony, they expressed strong enthusiasm for supporting screening. “It good that the awareness is made and spreads through different means to help people benefit from the importance of this message... it has encouraged and motivated me to support my wife.” (34 years old, married with children, Islamic religious leader) “So, with this information, I can be helping her to go and do the screening... so that she will get well and so that she can get pregnant.” (39 years old, married with children, occupation businessman) “So, most of them who have been facing this birth issues with their wives... it is a result maybe of the cervical cancer, so they have to encourage their wives. So when you talk to them this way, no one wants to have a problem in their family…so it will encourage them more.” (64 years old, married with children, unit community leader)
A Summary of the Implementation Ideas That Men Believed Would be Highest Impact to Increase Cervical Cancer Screening in Their Community in Northern Ghana
Discussion
The findings of this study highlight the importance of framing cervical cancer prevention within broader notions of family health and wellbeing, particularly in patriarchal settings where men play central decision-making roles. Participants frequently linked support for screening to concerns about fertility and reproductive health, suggesting that positioning cervical cancer screening as a means of protecting fertility and sustaining family welfare may foster stronger male engagement. This finding is consistent with prior literature describing factors associated with male engagement in cervical cancer screening in Africa. Prior research and this study together emphasize the value of family-centered approaches in sexual and reproductive health interventions. 221-23
Participants also demonstrated a high level of trust in healthcare professionals, indicating a key opportunity to strengthen cervical cancer education through provider-led initiatives. While prior evidence demonstrates a lower overall level of trust in the healthcare system in Ghana, this finding from our study indicates that trust is context dependent, in both the region sampled and for sexual and reproductive health services specifically.49-51 Screening promotion interventions embedded within existing care pathways may therefore be more acceptable than stand-alone outreach efforts, particularly given men’s openness to receiving health information from trusted professionals. However, men described financial constraints and competing household priorities that often limit the translation of knowledge into preventive action. These findings underscore the importance of integrating cervical cancer screening education into routine health services where men are already present, such as antenatal care (ANC) visits, to minimize additional time and cost burdens.11,29,30,52 Introducing cervical cancer prevention discussions within ANC may also facilitate early buy-in and normalize men’s involvement by positioning screening as a shared family health responsibility.
Consistent with this, participants expressed a strong desire to accompany their wives to healthcare facilities, reflecting a sense of responsibility and involvement in reproductive care. However, prior studies have documented health system barriers to male accompaniment, including long wait times and unwelcoming attitudes from healthcare providers.53,54 Addressing these barriers may be critical to maximizing the effectiveness of male engagement strategies. Efforts to intentionally include men within ANC and screening programs may not only improve access to preventive services but also strengthen partnership, shared responsibility, and sustained male support for women’s engagement in cervical cancer prevention. 52
Although men in our study demonstrated low familiarity with cervical cancer screening, consistent with previous studies, education was frequently emphasized as important during interviews.18,27 Men’s motivations for supporting screening were shaped by beliefs related to fertility, reproductive outcomes, and family stability, similar to patterns observed in prior systematic reviews of male engagement in cervical cancer prevention. 16 Prior literature suggests that cultural beliefs and myths about screening, including misconceptions linking screening to promiscuity or sterility, may further influence male engagement. 3 While these beliefs were not explicitly explored in this study, interventions may address such perceptions by leveraging men’s trust in healthcare providers as credible messengers.
Overall, this study provides insight into men’s perspectives on cervical cancer screening within their roles as family leaders and providers. Men described financial, emotional, and cultural responsibility for their wives’ health, particularly within the context of reproductive care. At the same time, societal norms and stigma may discourage visible male involvement, such as accompanying partners to health facilities.29,30 These findings suggest that cervical cancer prevention programs should not assume male opposition or disinterest. Instead, initiatives should build on men’s existing sense of responsibility, trust in healthcare systems, and openness to medically framed information.22,23 Community-based strategies that engage trusted male leaders and healthcare professionals as educators may help normalize male participation in reproductive health and strengthen cervical cancer prevention efforts in low-resource settings.10,55
However, while education for men with a focus on family centered messaging is a promising strategy to engage men as champions of cervical cancer screening, it is critical to implement these programs with careful consideration of women’s autonomy, rights, and equity. Male involvement must be framed in a way that complements and empowers women, rather than reinforcing patriarchal norms that may limit their agency in healthcare decision-making. Effective cancer prevention interventions must strike a balance between fostering male engagement and prioritizing women’s voices, ensuring equitable access to cervical cancer prevention services. Recognizing the complex interplay between culturally embedded gender roles, individual health agency, and trusted healthcare relationships is vital for designing interventions that are both impactful and inclusive.52,56,57
Limitations
Limitations of this study include the relatively small sample size, although we did achieve thematic saturation. The use of purposive sampling rather than random sampling may have limited the diversity of participants, potentially narrowing the perspectives represented when compared to the broader community. Additionally, while this study provides valuable insights into male engagement in cervical cancer prevention within the Ghanaian context, it is important to consider these findings in the larger body of evidence on cervical cancer screening uptake across Africa. This broader context can help situate the results and ensure their applicability to settings with similar social and cultural dynamics.
Conclusion
Our findings suggest that men are important stakeholders in the global effort to eliminate cervical cancer. Their values, previous experiences engaging with healthcare, and the influence of cultural and gender norms significantly impact their receptivity to supporting cervical cancer screening and prevention efforts. The evidence presented in this study highlights various social, cultural, and gender norms that affect cervical cancer screening within a local Ghanaian community. These insights can inform the development of targeted outreach and educational programming to encourage men to actively support cervical cancer screening for their wives and women within their families, ultimately helping to decrease the global cervical cancer burden.
