The cradle remains empty: 1.47 is the figure
“We are dying out, if we look at it objectively,” says Annemieke Dubois (Jade & Jules). In her practice, she sees the human side of the statistics every day: successful women like 38-year-old Sophie, who is paying for her freedom with her fertility. “Women are being sent to fertility clinics in droves, whilst men are left under the illusion that they have all the time in the world. It is the greatest medical myth of our time.”
Sperm quality in free fall
The facts are just as unforgiving for men as they are for women. Recent meta-analyses by the University of Oxford show that sperm concentration in the West has fallen by 50% over the past forty years.
Vanessa Muyldermans: “The ‘eternal thirty-something’ who thinks he can still easily become a father at fifty is being overtaken by science. After the fortieth birthday, the risk of DNA fragmentation in sperm cells rises significantly. This not only makes conception more difficult, but also increases the risk of miscarriages and genetic conditions such as autism or ADHD. The male biological clock is ticking, but we have left the batteries out for too long.”
‘Gender Vertigo’ and the qualification gap
Alongside the biological reality, there is a socio-psychological phenomenon that Dubois calls ‘Gender Vertigo’. The dating market is out of balance due to a growing gap in education and emotional well-being:
* The Qualifications Gap: Over 55% of Belgian women are highly educated, compared to less than 40% of men. Women would rather wait than marry ‘below their station’ (hypergamy), which leads to a forced pause in fatherhood.
* Emotional poverty: Whilst women build strong social networks, men are more likely to be left isolated after a break-up, which raises the threshold to a new, stable relationship.
* Relationship fatigue: In a ‘swipe culture’ where genuine attachment has been traded for a quest for something better, both genders lose precious time.
The rise of ‘Social Sperm Freezing’
In response to this uncertainty, an American trend is making its way into Belgium: men in their thirties having their sperm frozen as a precautionary measure. Dubois: “The fact that men are now turning to technology to stop time in its tracks proves that the pressure on the current dating market has become unsustainable. We must stop leading men to believe that their time is unlimited.”
