That’s according to new research from a leading fertility clinic, which found that men contribute to around half of all infertility cases in Australia. Yet everyday habits like drinking and vaping are largely ignored, with the medical and societal spotlight still glaring heavily on women. Australia is currently experiencing record-low fertility rates, with ABS data showing a plummet to just 1.48 births per woman annually. This decline is primarily driven by a number of social and economic factors, such as extreme cost-of-living pressures, broader concerns
about the future, and couples waiting longer to start families. But as those timelines get pushed back, the onus remains entirely on women to freeze their eggs early and prepare for the future, while men continue to fly seamlessly under the radar. Dr Anthony Marren, Medical Director at Genea Fertility, said ignoring the male side of the equation is a massive blind spot. “Traditional infertility investigations often start with the female, delaying evaluation of the male,” Dr Marren told news.com.au. He added that men are
far less likely to test their sperm due to lingering cultural stigma and the perception that infertility is “a threat to masculinity”. As a result, women are left carrying the exhausting burden of lengthy medical testing and lifestyle overhauls when trying to conceive. Small habits, big impact While a lot of attention goes to female egg health, experts are warning that a man’s everyday lifestyle choices could be quietly destroying sperm quality. Dr Marren singled out e-cigarettes as a rapidly emerging and scariliy underestimated threat.
“E-cigarette aerosols contain nicotine, aldehydes, metals, and flavourants that can generate reactive oxygen species,” he warned. This toxic mix directly attacks the body, and can lead to heavily damaged sperm DNA. Similarly, when it comes to the great Aussie past-time of drinking a few beers with mates on the weekend, the medical advice is surprisingly brutal. “There is no ‘safe’ alcohol threshold for sperm,” Dr Marren warned. While the occasional glass of wine with dinner might be passable, the official advice for couples trying to
conceive is for men to ditch the booze entirely. But the list doesn’t end there. Everything from carrying extra weight to poor sleep can actively sabotage sperm health. Even seemingly ‘harmless’ habits — like saunas, spending hours in a hot spa, prolonged sitting at a desk, or squeezing into tight underwear — can overheat testicles and damage sperm quality. The male fertility clock myth On top of that, we’ve all quietly embraced the notion that men can father children well into their later years —
but the evidence paints a different picture. Just like women, men do indeed have a biological clock and it starts ticking down way earlier than you might think. “Gradual decline begins in the mid-30s and accelerates after 40,” Dr Marren explained. Older sperm can be correlated with a much longer wait for a positive pregnancy test, heavily reduced natural conception rates, and a significantly higher risk of miscarriage. It can also lead to poorer outcomes in exhausting fertility treatments like IVF as well as genetic
risks for the baby. A fertile future? Despite the shocking findings, experts say they’re noticing a positive shift when it comes to Aussie men being more proactive. Genea Fertility has recorded a major spike in men booking fertility tests and seeking support, and a shift towards reframing fertility as a “couple issue” rather than women’s issue. Interestingly, there is also a surging demand for vasectomy reversals. For men who have met a new partner or simply changed their minds about having kids, a reversal procedure
is proving to be a highly effective option. Dr Marren noted that success rates for reversing the procedure can hit up to 90 per cent, resulting in actual pregnancy rates of 50 to 70 per cent. But whether it’s reversing the snip, ditching the vape, skipping the weekend beers, or visiting a specialist, the message for Aussie blokes is crystal clear. The days of leaving the fertility burden entirely to women are finally over.

This is why they never take women seriously until it’s too late. Like the men’s “radar” thing is real, my cousin did all the tests first and her husband acted like it was her problem. But then they say men contribute to half? Half what, exactly? Fertility is so complicated it feels like a stretch to connect drinking/vaping to “destroying sperm DNA” like overnight.
