Male Fertility

Male fertility matters more than people think.

Around 40% of fertility challenges involve a male factor, either alone or alongside a female factor. Conception is a two-person process, and male preconception nutrition is just as important as female.

The 90-day sperm cycle

It takes roughly 90 days for sperm cells to fully develop from start to finish. The sperm available at any given moment was created from precursor cells about three months earlier. This means every nutrition, lifestyle, and exposure choice in the 90 days before conception influences sperm quality at the moment of conception.

What "sperm quality" actually means

Sperm quality is a combination of four things:

• Count. The number of sperm per millilitre.
• Motility. How well sperm swim.
• Morphology. The percentage of sperm that are normally shaped.
• DNA integrity. The chromosomal health of the sperm cell itself.

All four respond to nutrition, lifestyle, and antioxidant status during the 90-day production window.

What affects sperm quality

• Oxidative stress (smoking, alcohol, pollution, processed food)
• Heat exposure (tight underwear, frequent saunas, laptop on lap)
• Selenium status. Selenium contributes to normal spermatogenesis
• Zinc status. Zinc contributes to normal fertility and reproduction
• CoQ10. Involved in mitochondrial energy production, including in sperm cells
• Folate, B12, B6. For DNA synthesis and integrity

What men can do today

While we finalise the men's formula, the broader nutrient principles still apply. A balanced diet rich in vegetables and oily fish. Limiting alcohol and processed food. Avoiding heat exposure to the testes. Zinc and selenium are particularly worth ensuring you get from food (or, if you and your doctor decide together, from a quality standalone supplement).
