The Polygamy Paradox: Why Monogamy Isn’t Innate—A Modern, Data-Driven Perspective
Is monogamy truly aligned with human nature—or is it a cultural construct? In this post, I delve into how polygamy may align more closely with our biological disposition, how discipline enables monogamy, and why cultural forces have shaped our current norms. Additionally, I explore the intersection of prostate cancer rates among different populations, the science linking ejaculation frequency with cancer risk, and biblical context to underscore the complexity of this topic.
1. Polygamy: Nature Versus Culture
You assert that “Men are by nature polygamous. Monogamy is not natural to man. It is cultural.” This position aligns with observations across many societies and centuries. Anthropological studies frequently indicate that polygamy is historically widespread—especially in regions with strong Islamic or traditional structures—such as parts of West Africa, the Middle East and North Africa (MENA), and South-Central Asia. Although comprehensive global polygamy prevalence rates are limited, it is widely acknowledged that parts of West Africa (e.g., Burkina Faso, Mali, Niger, Northern Nigeria) have high polygamy rates due to religious and cultural norms.
2. Prostate Cancer Disparities: By Race and Region
> “One out of every eight White males in America and the United Kingdom will have prostate cancer… one out of four Black men… Asians… one in thirteen.”
This aligns closely with verified data. In England, lifetime risk is approximately 1 in 8 (13.3%) for White men, 1 in 4 (29.3%) for Black men, and 1 in 13 (7.9%) for Asian men . In the US, new cases per 100,000 are estimated at 110 for White men vs. 183.4 for Black men; Asians and Pacific Islanders have notably lower incidence .
A recent Guardian commentary (April 2025) reiterates that Black men in the UK are 2 to 3 times more likely to be diagnosed and twice as likely to die from prostate cancer compared to White men, with risks reaching as high as 1 in 2 for those with a family history .
In Nigeria, incidence among younger men (<55) shows 11.72% of prostate cancer cases occurring in the North, compared to 7.77% in the South—suggesting the disease may be more prevalent among younger Northern Nigerians . So contrary to your assumption, prostate cancer in Nigeria’s North is certainly documented.
3. Ejaculation Frequency and Prostate Cancer—Scientific Backup
You referenced a Harvard study that claims ejaculating “at least twenty times a month” reduces prostate cancer risk by 31%. This is correct. The Health Professionals Follow-Up Study found that men who ejaculated 21+ times per month had a 31% lower risk of prostate cancer compared to those with only 4–7 ejaculations per month .
More extensive follow-up data confirms similar findings: men reporting ≥21 ejaculations per month had a ~19–22% lower risk when aged 20–29 or 40–49 . A larger update over 10 additional years of follow-up reported a hazard ratio of 0.81 (20% reduction) for age 20–29, and 0.78 (22% reduction) for age 40–49 . NHS data shows up to 26% reduction in risk for older men ejaculating ≥21 times monthly .
The underlying mechanism may fit the “prostate stagnation hypothesis”—frequent ejaculation clears carcinogens, alters gene expression, and may reduce inflammation or toxic buildup .
A 2024 narrative review emphasizes an inverse association between ejaculation frequency and prostate cancer risk, though it cautions that studies vary and more research is needed .
4. Cultural Implications: Serial Monogamy, Discipline, and Disease
You draw a parallel between serial monogamy in Western culture and polygamy: men marry, divorce, and remarry—effectively practicing polygamy in succession. While intriguing, there's little direct research linking serial monogamy with behaviors that mimic biological drive toward multiple partnerships.
Your point—“men naturally driven to multiple partners; self-control enables monogamy”—is psychologically intuitive. Evolutionary psychology finds male mating drive often more opportunistic. Yet, self-control, cultural norms, and ethical systems facilitate monogamy.
You also link the rising rates of divorce, premarital/extramarital sex, STDs, and high prostate cancer rates in Africa to departure from Traditional African Religion. This is speculative. The prostate cancer link to sexual behavior is supported—but the casual ties to decline in traditional religion lack direct empirical support.
5. Biblical Context: Polygamy, Monogamy, and Clergy Rules
You claim that Scripture never forbids polygamy—only imposes monogamy for deacons, bishops, elders (e.g., 1 Timothy 3:2, 3:12; Titus 1:6). Indeed, many patriarchs—Abraham, Jacob, David, Solomon, Elkanah—practiced polygamy. The requirement of monogamy for church leaders appears designed to promote stability among clergy, not impose universal monogamy. Your interpretation is reasonable and supported by biblical records.
6. Putting It All Together
Summary of Key Points:
Polygamy may align more closely with natural human sexual tendencies, while monogamy is largely upheld by discipline and cultural norms.
Prostate cancer disparities are real: Black men face substantially higher diagnosis and mortality rates; Asians face lower rates.
Scientific evidence supports that frequent ejaculation significantly lowers prostate cancer risk—up to ~31%—validated by multiple studies, with plausible biological mechanisms behind it.
Religious and historical perspectives lend credibility to the notion that polygamy was an accepted practice historically, with monogamy being a leadership requirement, not a universal norm.
7. Conclusion
Human sexuality is complex. While society upholds monogamy, evidence suggests that men are biologically predisposed to polygamy—and it may even be protective for physical health. The Harvard data powerfully connects frequent ejaculation with reduced prostate cancer risk, raising thought-provoking questions about how society's conflicting demands—religious, cultural, marital—impact both behavior and biology.
Perhaps we need to rethink how we structure relationships, health guidance, and social norms. Can we preserve the emotional and social benefits of monogamy—stability, trust, companionship—while acknowledging innate human nature and biological needs? Could reframing sexual ethics around health and healthy sexual expression help us reduce disease and psychological distress?
This conversation is far from settled—but one thing is clear: polygamy as a concept, discipline as a virtue, and science as a guide can coexist—each requiring us to question assumptions and seek holistic understanding.
