Nutrients for male infertility

What are the top 3 Nutrients for male infertility and sperm health? Have you ever considered the role of nutrients for male infertility and sperm health? The fact is that male factor infertility contributes to around 50% of all infertility cases. We’ve seen a 50% declined in sperm count from 1973 to 2011! 

The concept of male preconception care, with the aim of improving sperm quality, has only recently started to gain traction at a public health level. Prior to this infertility was always a women’s problem, which is most definitely not the case.

I encourage all my infertility clients to get their sperm tested and I use optimal sperm parameters to interpret the results. When using the standard ranges included on sperm analysis results, male factor infertility is frequently missed.

Recently, I had a male client who sent me his sperm analysis results. He told me that his doctor hasn’t found any issues and that his sperm were all normal. When I assessed the sperm analysis, I found he had poor sperm motility and morphology, which is a contributing factor to male factor infertility.

So how can we improve sperm quality? Well, I’m glad you asked! Let’s cover the top 3 nutrients for male infertility. That means they help to improve sperm quality and quantity, to help with male factor infertility. Let’s talk about zinc, vitamin D, and the omega 3, DHA.

Nutrients for Male Infertility

Zinc for male infertility

Zinc is an important nutrient for male infertility. Poor Zinc status is an important risk factor for the low quality of sperm and unexplained male infertility.

It can contribute to:

  • • Low testosterone
  • • Low sperm count
  • • High levels of abnormal sperm


Vitamin D

Research has concluded that Vitamin D is likely essential for sperm production and function, as vitamin D receptors have been found in the sperm & testis. This means that vitamin D has a role in spermatogenesis, i.e., the creation of sperm.

It’s important to note that BOTH low (<50 nmol/L) & high (>125 nmol/L) levels have been associated with poor semen parameters. As always, I recommend testing your vitamin D levels prior to supplementation with a therapeutic dose of vitamin D, so you know if you have low or high vitamin D that could be contributing to low sperm count.



Docosahexaenoic acid (DHA) is an omega-3 fatty acid found in cold-water, fatty fish, such as salmon or vegan sources from algae. It’s a vitally important nutrient for male infertility, particularly poor morphology. Research shows that abnormal sperm have reduced concentrations of Omega 3s. This is significant because 20% of the head of a sperm is made of DHA and it’s needed to mature sperm.

A meta-analysis found that that supplementing infertile men with omega-3 fatty acids resulted in a significant improvement in sperm motility and concentration of DHA in seminal plasma.
