Fructose is a sugar in the semen. It provides energy for the sperm. If it is too low, the sperm will be disadvantaged at swimming to and fertilising an egg.

The absence or low fructose levels in semen may indicate a problem with the seminal vesicles1

The World Health Organisation regards 13 μmol (or approximately 3 mg/ml) as the lower reference limit for the amount of fructose per sample2.

Male fertility is declining

Carlsen et al analysed a total of 61 studies including 14,947 men from the years 1938 to 1991, for mean sperm density and mean seminal volume. Their results show a significant decline in mean seminal volume from an average of 3.40 ml to 2.75 ml (p=0.027)3, 4
This demonstrates a 20-percent drop in volume and a substantial 58-percent decline in sperm production over the last 50 years.

Statistics and Causes

One in six couples (15%), who are attempting to conceive naturally fail to do so in 12 months and are therefore considered “subfertile”. Approximately 40% of these cases are caused by “male factor” infertility5. Although the causes are still not well understood, they are often linked to poor diets low in key nutrients and increasing exposure to toxins in our environment.

How to increase male fertility

There are a number of things a man can do to improve his fertility. These include lifestyle choices such as the elimination of fast food, nicotine and alcohol, regular exercise, restful sleep and the reduction of stress.

In addition, scientific studies have show that an increase in sperm count can be achieved by taking the following food supplements:

  • amino acids such as Arginine and Carnitine
  • antioxidants such as Glutathione and and co-emzyme Q10
  • trace metals such as zinc and selenium
  • vitamins such as A, B9 (folic acid), C, D and E
  • extracts such as pine bark extracts (Pycgnogenol)

These amino acids, vitamins and trace elements are naturally occurring nutrients and no side effects are to be expected. On the contrary, increasing the supply of such micronutrients causes significant health benefits such as a stabilisation of the immune system, a positive effect on cardiovascular circulation and skin and hair health.

There is therefore no medical reason not to implement a micronutrient rich diet for a half or a full year.

Male fertility supplements combine many of the nutrients to create one powerful fertility-enhancing pill.
