Male Fertility

Learn how to improve sperm health prior to conception. 

Sperm counts among men have more than halved in the last 40 years, research suggests, although the drivers behind the decline remain unclear. The latest findings reveal that between 1973 and 2011, the concentration of sperm in the ejaculate of men in western countries has fallen by an average of 1.4% a year, leading to an overall drop of just over 52%.

A 2017 published comprehensive meta-regression analysis reports a significant decline in sperm counts (as measured by SC and TSC) between 1973 and 2011, driven by a 50–60% decline among men unselected by fertility from North America, Europe, Australia and New Zealand. [1]

So what does this mean for you? You and your partner might be finding it difficult to get pregnant. Your semen analysis might have shown you are sub-fertile. Or maybe you are simply aware that the health of your sperm prior to conception is crucial to a successful pregnancy and to the health of your unborn child and you would like to improve your own sperm health. Either way, I can help. 

1 in 6 NZ couples are affected by infertility or the inability to conceive after 12 months of unprotected intercourse. Research shows that male factor infertility is responsible for up to 40% of all these cases, and 20% is attributed to combined male and female infertility [2]. 

The good news is that male factor infertility issues can almost always be overcome!

Some Reasons for Poor Male Fertility

Did you know that it takes 4 months for sperm to be produced and mature prior to ejaculation? 

Think back over the past 4 months. Did you make healthful lifestyle choices which support the healthy conception, pregnancy and birth of your child? Did your lifestyle choices lead to improved sperm health? Or is it possible that poor lifestyle choices have contributed to poor-quality and/or -quantity of sperm, DNA fragmentation, chromosomal abnormalities and/or sub-fertility? 

A few examples …

  1. Male smokers have been shown to have lower sperm counts and more sperm abnormalities affecting male fertility. AND their partners are also more likely to have problems conceiving and suffer increased rates of miscarriage [3].
  2. Sperm of overweight men is associated with higher rates of chromosomal abnormalities, which in turn also increases miscarriage risks [4]. 
  3. A 2018 study on the link between drinking soft drinks and reduced fertility revealed that ‘Men who drank at least one soda drink daily had a 33 percent lower probability of successfully conceiving with their partner’. [5]
  4. Mercury toxicity (e.g. from silver amalgam fillings in your teeth) can lead to low sperm count, defective sperm & sperm with poor motility. I work in conjunction with dentists who perform safe amalgam removals, offering a mercury detox programme.
