Men often do not receive the proper attention in health matters: While female fertility stands at the center of the medical and public discourse, sperm quality often remains out of the spotlight – even though it is a broad indicator of overall male health: From hormonal balance, through energy levels, to the risk of chronic diseases.

In other words, sperm quality is not only a matter of reproduction – but also of vitality, strength and longevity.

Veronica Maisler, a clinical dietitian in the NLP method and a consultant for Herbalife, explains: “Recent studies indicate that a decrease in sperm parameters is not only a matter of fertility, but a broad health marker. Low sperm quality has been found to be associated with an increased risk of cardiovascular disease, metabolic syndrome and early mortality – even among men who do not suffer from significant fertility problems.”

Sperm quality reflects the body's hormonal, nutritional and oxidative balance – it is a kind of “inner window” into male health.

Nutrition affects – much more than we thought

Not only age or genetics determine sperm quality, but also – and very much – the plate. Western dietary patterns high in ultra-processed foods, saturated fats, processed meats, sugars and alcohol have been linked to a significant decline in sperm count, motility and DNA integrity.

In contrast, men who adopted a Mediterranean pattern rich in vegetables, fruits, fatty fish, nuts and olive oil showed improved parameters of sperm quality and hormonal health.”

“This is not just theory,” adds Maisler. “It can also be seen in clinical practice, that in many cases consistent dietary change leads to real improvement in male health markers: A decrease in inflammation markers, an increase in energy and vitality, and sometimes even a significant improvement in sperm quality.”

Patience pays off: Why three months are needed?

In order for a real effect on sperm quality to occur, at least three months of dietary and lifestyle change are required – since this is the period of time in which the body produces and matures a new generation of sperm cells.

Only after the new sperm cells are created in healthier conditions, a measurable improvement can be seen in laboratory tests – and sometimes also a tangible change in the feeling of energy and vitality.

Sperm quality is measured according to several parameters: The concentration of sperm cells, their total count, their motility, their shape and the integrity of the DNA within them. DNA is the “instruction manual” of life – when parts of it are damaged, it is like a book with torn pages or missing sentences.

When breakage levels are high, the likelihood of fertility problems, early miscarriages and embryos with low developmental potential increases.

The “silent” inflammation – the hidden enemy

One of the main reasons for DNA damage in sperm is “silent” inflammation – a condition in which the body is under ongoing internal stress. This inflammation is not always felt, but it may manifest in chronic fatigue, brain fog, mood swings and vague pain.

Processed food and a diet low in antioxidants accelerate aging processes and intensify internal inflammation. It can be compared to rust eating away metal from the inside – only this time it happens at the cellular level.

Alcohol also directly affects sperm quality. Daily or regular consumption, even “moderate”, may cause DNA breakage and damage motility.

The practical guide: How to improve sperm quality through nutrition

1. Adopt a Mediterranean diet


• 5 colors a day – vegetables and fruits in a wide variety


• Fatty fish 2–3 times a week – salmon, tuna, mackerel


• Nuts, legumes, olive oil and yogurt – sources of essential nutrients

The shift in thinking: From “I need to eat healthy” to “I am nourishing my body so it can be capable of creating life.”

2. Reduce ultra-processed food


Industrial pastries, cold cuts, sweetened drinks and snacks shut down long-term energy. Every time you reach for such food – stop for a moment and ask: “What do I really want – momentary taste or energy for life?”

3. Enrich the body with antioxidants


Berries, kiwi, pomegranate, spinach, broccoli, parsley, almonds and walnuts – these are not just nutrients, but the “bodyguards” of DNA.

4. Maintain a healthy weight and reduce stress


Abdominal obesity and psychological stress increase oxidative stress and impair fertility. Try to identify the “triggers” of the stress – situations, thoughts or people – and learn to respond to them differently.

Sperm quality is not just a matter of fertility – it reflects overall health, vitality and the potential for longevity. Simple changes in nutrition and lifestyle can change the picture within three months, and influence not only the ability to create life – but also the quality of life itself.
