Improving Sperm Quality with Diet

How can you improve Sperm Quality and fertility naturally?

Recent research for Male Fertility has led to Cambridge IVF clinic to be the first clinic to offer an Oxidative Stress Level Test (ROS semen test) in the UK.

This is a significant step forward, as poor quality sperm is now know to be causing 50% of infertility cases (previously it was only thought to be around 20%).

Sperm produce small amounts of free oxygen radicals (ROS) that are required for normal function. Antioxidants present in the sperm environment keep these levels low. However, if this balance is disturbed, levels of free oxygen radicals rise, causing oxidative stress. This leads to sperm damage and consequently affects fertility.

What can we advise for this? Diet and lifestyle changes are the best approach for male fertility but there are many suggestions available. A bespoke diet and lifestyle plan will provide you with the answer.

What do we know about Oxidative Stress in Male Sperm Quality?
  • ROS levels can be high in men who have been tested previously and told they have ‘normal’ semen parameters.
  • High ROS levels cause sperm DNA fragmentation.
  • High ROS levels are correlated with an increased time to achieve a natural pregnancy.
  • 25 – 40% of infertile men have high levels of ROS and a reduced antioxidant capacity, compared with fertile men.
  • High ROS levels impair fertilisation, affect blastocyst development and reduce pregnancy rates after IVF.
What nutritional changes will help reduce Oxidative Stress in Sperm?

Randomised placebo controlled studies have shown that anti-oxidant supplements can reduce ROS levels and sperm DNA damage, and improve pregnancy rates. Increased levels of ROS may be reduced with changes in lifestyle and a diet rich in anti-oxidants.
