The decision to become a father later in life is increasingly common, driven by shifting societal norms, career demands, and personal choices.

But as Millie Odhiambo, MP for Suba North, pointed out recently, “Nowadays, because of peer pressure, you’ll still find an 80-year-old man wanting to have a child.”

While the desire to extend one’s legacy or fulfill personal dreams is understandable, older fatherhood, typically defined as men over 50, comes with serious medical, social, and ethical implications. It’s a decision that demands sober reflection beyond the romanticised idea of late-life parenting.

Medical and physical realities

From a medical perspective, advanced paternal age is associated with increased health risks for both the child and the father. Research consistently shows that older fathers are more likely to pass on genetic mutations to their offspring.

A 2018 study published in The BMJ found that children born to fathers over 45 face higher risks of autism, schizophrenia, and certain congenital disorders because of age-related changes in sperm DNA.

Similarly, a 2019 study in Nature revealed that older men have a higher likelihood of passing on de novo mutations, which can lead to developmental issues. For some rare genetic conditions like Apert syndrome, men over 50 are up to five times more likely to have affected children compared to those under 30. These are not distant risks; they are medically documented realities.

The fathers themselves are not spared. Men above 50 are more prone to cardiovascular disease, diabetes, and mobility challenges. A 2020 study in The Lancet noted that men over 60 have a significantly higher mortality risk, raising concerns about their ability to offer long-term care and support.

Parenting involves physical demands, late nights, active play, and emotional resilience, and these responsibilities can be overwhelming for older fathers, potentially affecting both their well-being and their child’s upbringing.

Social and generational gaps

Beyond health, older fatherhood brings social complexities that are often underestimated. Children of significantly older fathers may grow up feeling a generational disconnect. A 2023 report by the Pew Research Center highlighted that these children often experience cultural gaps, making it harder to relate to their parents on everyday issues.

In Kenyan settings, where school events, birthday parties, and peer interactions are vibrant parts of childhood, an older father may find himself out of place among younger parents. This can create a sense of isolation for both father and child.

Millie Odhiambo’s remarks also shed light on peer pressure. In many communities, older men feel compelled to “prove” their virility or maintain a legacy. But this pressure can overshadow practical considerations; raising a child at 70 or 80 comes with inevitable social challenges that can’t be ignored.

Ethical and financial questions

There’s also an ethical side to this conversation. A child born to a 70-year-old father may lose their parent before reaching adulthood. The World Health Organization puts the global male life expectancy at around 73 years. This means there’s a real possibility that such fathers may not witness key milestones in their children’s lives, like graduations or weddings. The emotional and financial burden that follows can be heavy for the child and the surviving family.

Financially, late fatherhood can stretch resources thin. A 2024 U.S. Department of Agriculture report estimates the cost of raising a child to age 18 at about $310,605 (excluding college).

For older men nearing retirement, this can mean tough choices between funding their twilight years and securing their child’s future.
