Experts weigh in
Male fertility decline has become one of the most important and unsettling questions in reproductive medicine. There appears to have been a clear decline in sperm quality over the past 50 years, but the difficult truth is that there is no single, settled explanation.
That was one of the central messages delivered by United States researcher Dr Michael Eisenberg at the Fertility Society of Australia and New Zealand annual scientific meeting in Canberra. He examined a range of possible contributors to declining male fertility, from obesity and heat to mobile phones, chemicals and plastics.
The answer, at this stage, is not a neat one. There may be several causes working together. What is clear is that male reproductive health deserves serious attention, proper research and practical medical care rather than simplistic political explanations.
What I find interesting that among the possibilities mentioned below, there is no discussion relating to environmental toxins and low nutrient diets.
The Question of Declining Sperm Quality
There has been substantial concern about declining sperm quality in recent decades. Some earlier research suggested that the trend may have begun during the twentieth century, although the reliability of parts of that older research has been questioned.
Dr Eisenberg’s focus was on the stronger apparent trend over the last half century. Sperm quality has fallen, and researchers are trying to identify why.
It is tempting to seize on one explanation. A former senator recently suggested that male fertility was declining because society had become “woke”. That may make for an eye-catching comment, but it does not assist anyone trying to understand a genuine health issue. Fertility is complicated. Human biology, environment, lifestyle and modern living may all be relevant.
The responsible answer is that researchers do not yet know precisely which factor, or combination of factors, is responsible. But several plausible areas warrant careful investigation.
Possible Causes of Male Fertility Decline
1. Obesity and Physical Health
One possible contributor is obesity. People are generally more obese now than they were 50 or 60 years ago, and poor physical health can affect many bodily systems, including reproductive health.
Men who are unfit or obese may be more likely to have poorer sperm quality. This does not mean that every man with a higher weight will experience fertility difficulties, nor that fertility issues can simply be blamed on body size. It does mean that overall health matters.
For men concerned about fertility, attention to fitness, diet and general wellbeing is sensible. These issues should be addressed with a doctor, particularly where pregnancy has not occurred after a reasonable period of trying or where there are known reproductive concerns.
2. Radio Waves, Mobile Phones and Wi-Fi
Modern life involves constant exposure to electronic devices. Mobile phones, wireless networks and other sources of radiofrequency exposure are now ordinary features of work, travel and home life.
Dr Eisenberg identified radio waves as a possible area of inquiry. Mobile phones are often carried in a trouser pocket, close to the testicles. Given that the testicles are reproductive organs sensitive to external influences, it is reasonable to ask whether this type of exposure could affect sperm production or sperm quality.
That question remains unresolved. It should not be presented as established fact that a phone in a pocket causes infertility. Equally, it should not be dismissed without ongoing research. Fertility medicine must be led by evidence, not assumptions.
I would beg to differ as research into the dangers of EMF is readily available but has not become mainstream as yet. You can read more about contributing factors in my book.
3. Chemicals, Plastics and Nanoplastics
Perhaps the most confronting area of research concerns chemicals and plastics. Plastics are everywhere in contemporary life. They are difficult to avoid entirely, appearing in food packaging, household goods, workplaces and consumer products.
Researchers are examining whether exposure to chemicals and plastics might contribute to reproductive changes. Of particular concern is the emerging study of nanoplastics, extremely small plastic particles that may enter the body.
Studies have identified plastic particles in men’s testicles. Research has also compared nanoplastics found in human testicles with those found in dogs’ testicles. That is a striking and deeply concerning subject for further investigation.
No responsible practitioner should jump from early findings to definitive conclusions. However, this research highlights why environmental exposure must remain on the agenda in fertility medicine. The question is not merely whether one substance is responsible, but whether a lifetime of combined exposures may affect reproductive health.
There May Be More Than One Cause
Obesity, heat, electronic devices, chemicals and plastics may each play a role. Some may have little effect on their own but become more significant in combination with other factors. There may also be influences not yet identified.
That uncertainty is not a reason for inaction. It is a reason for better research and thoughtful clinical practice. Where doctors can identify lifestyle factors or exposures that may be relevant for a particular patient, they can help reduce risks and support the best possible reproductive outcomes.
People considering fertility treatment or concerned about reproductive options should obtain advice tailored to their circumstances. I highly recommend consulting a qualified fertility trained naturopath who is able to assess your individual needs and spend the time needed to get to know you and your situation.

My comments in italics.
Bottom line: ensure you get professional advice and take the time to properly prepare your body BEFORE trying to conceive. This applies whether you intend on natural conception or assisted, including IVF. You can read more in my book which is available on Amazon.
