As long as people do not want to have children, or certain types of children, they will search for a way to avoid it. In a recent CNN report on reasons why a small but growing number young men have been freezing their sperm, achondroplasia was listed as one of the conditions the risk for which is associated with advanced paternal age. While the report cites single studies finding an increased risk for various conditions and disorders, many studies over the past two decades have linked achondroplasia to advanced paternal age. (Perhaps Mick Jagger should educate himself, if he hasn’t already.)
Most people with achondroplastic dwarfism are born to non-achondroplastic parents like mine. (“Are you parents little, too?” is one of the most common questions I get from strangers.) Most of us grew up told that our genetic mutation could not be traced to any known source. That is now changing, as news networks repeat the link to advanced paternal age.
My father was 28-years-old when I was born, hardly what we in the West think of when we envision advanced paternal age. All but one of my friends with achondroplasia have parents that were roughly the same age as my own when they were born: that is, late 20s or early 30s. And the majority of my friends with achondroplasia are first-borns.
Anecdotal evidence is often rife with bias, so I cannot officially dispute the researchers’ findings. Perhaps my friends and I are simply exceptions to the rule just like every smoker can name someone who beat the odds and puffed their way to age 95. But my personal experience easily invalidates any argument that men who freeze their sperm in their 20s or 30s are on a clear path to avoiding fathering a child with achondroplasia.
Bioethicists are divided on whether or not to advise men to freeze their sperm to avoid various conditions. Regardless of the answer, men should hear that the statistics on achondroplasia and age risk imbuing them with an inflated sense of control. One could say most forms of genetic counseling do.
