The Hidden Crisis: Male Infertility and Its Impact on Mental Health
There is a common misconception that physical fitness equates to reproductive health. This belief is deeply ingrained in modern masculinity, where the ability to run a marathon or maintain a lean physique is often seen as a marker of overall wellness. However, this assumption can be dangerously misleading, especially when it comes to male fertility. For many men, the reality is far more complex, and the consequences of not addressing reproductive health can be profound—both physically and emotionally.
In Australia, one in three assisted reproductive technology cycles is used because of a male factor, and male infertility contributes to half of all couples who struggle to conceive. Despite these numbers, male reproductive health remains an under-discussed topic, often overshadowed by the focus on female fertility. This lack of awareness can leave men unprepared for the emotional and psychological challenges that come with an infertility diagnosis.
The Fitness Fallacy: Why Physical Health Doesn’t Guarantee Reproductive Health
Dr Darren Katz, Clinical Associate Professor and Medical Director of Men’s Health Melbourne, explains that while being physically fit is beneficial, it does not necessarily reflect the state of a man’s reproductive health. “Being physically fit and appearing healthy externally does not necessarily reflect what is happening at a cellular level in the testes,” he says. “I see men in excellent physical shape who still have significantly impaired sperm counts due to genetic conditions, hormonal problems, prior infections, or varicoceles.”
Some of the habits most associated with peak physical performance can even work against fertility. Anabolic steroids, which are increasingly common in gyms, can shut down sperm production entirely, and the damage isn’t always reversible. Extreme dieting and overtraining also carry similar risks, as they can disrupt the hormonal environment needed for healthy sperm production.
Outside the gym, other factors such as poor sleep, chronic stress, smoking and vaping, heavy drinking, recreational drugs, frequent sauna or spa use, and carrying excess weight can also impact fertility. These issues may not feel like fertility problems in the moment, but they can have long-term consequences.
Age is another overlooked factor. While women are often warned about the ticking biological clock, men rarely receive the same message. After around 45, sperm motility tends to decline, and DNA fragmentation increases, which can lead to longer conception times, higher miscarriage rates, and an increased risk of certain neurodevelopmental conditions in children.
The Fertility Conversation That’s Been Leaving Men Out
When a couple struggles to conceive, the clinical default has historically been to focus the investigation on the woman. She gets the workup, the monitoring, and the interventions, while the man provides a sample and waits. This dynamic, according to Dr Katz, is both persistent and damaging.
Fertility investigations have often focused disproportionately on women, despite male factors contributing to infertility in roughly half of all couples. Dr Katz spent two years leading the development of Australia’s first national clinical guidelines on male infertility, which produced 80 evidence-based recommendations. One of the most significant is that both partners should be assessed concurrently from the very beginning of any fertility investigation, not sequentially, and not only after the female workup draws a blank.
The data makes the case plainly. A male factor contributes at some level in 50 per cent of infertile couples and is the sole explanation in 20 to 30 per cent of all cases. In Australia, one in three assisted reproductive technology cycles is used because of a male factor. And yet culturally and clinically, male infertility is still treated as a secondary concern, something to rule out rather than something to actively investigate.
‘I Felt Really Isolated’: Reece Conca On His Experience With Male Infertility
Former AFL player Reece Conca was in the best physical condition of his life when his test results came back showing low testosterone and a low sperm count. The eventual diagnosis was azoospermia, the complete absence of sperm in the ejaculate, and for someone whose sense of self had been built around physical performance and athletic identity, the psychological impact was significant in ways he hadn’t anticipated.
“It was definitely quite a confusing diagnosis, mainly because it was so unknown and I didn’t really have any awareness or education around it,” Conca said. Beyond the confusion was a visceral feeling of shame, one that cut straight to his sense of who he was.
“It was really quite embarrassing. I had this real sense of shame, and even my identity as a male, as an athlete. I really struggled with that.”
His experience isn’t unusual, even if it rarely gets discussed. In 30 to 40 per cent of male infertility cases, no specific cause is ever identified, meaning men go through the entire diagnostic process and come out the other side without a clear answer.
Varicocele, a condition affecting up to one in seven men and one of the most common reversible causes of male infertility, frequently goes undetected because there are no obvious symptoms. Men assume they’re fine because nothing feels wrong.
Redefining What It Means to Be a Strong Man
An infertility diagnosis has a way of forcing a reckoning with identity that most men aren’t prepared for, particularly men who’ve built their sense of self around physical capability. If the body is supposed to be the measure of the man, what does it mean when it doesn’t perform in this particular way?
For Conca, working through that question took years of psychological support, a lot of difficult conversations, and eventually fatherhood.
“The purpose that I have in being a father now is more important than anything. This idea of being a strong male, my identity, it definitely isn’t shaped by my masculinity or my identity as an athlete. My ability to communicate and talk about my feelings, that’s a real strength.”
The Proactive Plan: 3 Steps to Check Your Fertility
For any man in his late 20s or early 30s who wants to be proactive, Dr Katz recommends three simple steps all men can take to understand their health better, and take proactive steps to address any issues.
Get a baseline semen analysis
“It’s a simple test and it gives you a reference point. Knowing this key bit of information early in the piece is critical and can also help to avoid unnecessary delays, as well as unnecessary tests for the female partner.”
Address lifestyle factors
From there, Dr Katz suggests addressing the modifiable factors like smoking, heavy drinking, steroid use, recreational drugs, heat exposure, and sleep quality.
Know your own history
If there’s any relevant history, such as a prior STI, undescended testes, surgery, cancer treatment, or a family genetic condition, get tested sooner rather than later.
Conca’s advice is less clinical but equally proactive. “Once you’ve made the decision that you and your partner are going to start trying to conceive, just be on the front foot. Your fertility health is just as important as your physical health, mental health, social health, and financial health. For some reason it’s just an afterthought for a lot of people, until it becomes an issue.”
Common Questions About Male Fertility
Can my gym routine or supplements actually damage my fertility?
Yes. While staying active is a pillar of health, certain “peak performance” habits can be counterproductive. As Dr Darren Katz notes, anabolic steroids and supplemental testosterone can shut down sperm production entirely, with damage sometimes being irreversible. Even extreme dieting or overtraining can disrupt the delicate hormonal environment required for sperm production. Bridging the confidence gap means understanding that external muscle mass is not always a reflection of internal reproductive health.
When should I consider getting a semen analysis?
For the modern Australian man looking to be proactive about his future, a baseline test is recommended in your late 20s or early 30s. Rather than waiting until there is a struggle to conceive, getting a “first look” at your reproductive health allows you to make informed lifestyle adjustments early on.
What are the most common hidden factors affecting male fertility?
Beyond obvious habits like smoking or heavy drinking, modern lifestyle factors such as chronic stress, poor sleep quality, and frequent heat exposure (like saunas or hot tubs) can significantly impact sperm health. Transitioning into fatherhood requires a holistic approach to health that balances career ambitions with physical recovery.
