In my quest to understand the importance of Antioxidants in improving sperm morphology, I've stumbled across a few useful promising studies.
This study is particularly fascinating, 13 patients with low sperm counts (but normal morphology) were given a whopping 2000mg of vitamin C a day for 2 months, and this was the result;
A huge uptick across the board! Importantly for me though Morphology saw a huge increase, and it appears that the lower the starting morphology, the greater the improvement.
This study also suggested lower levels of vitamin C leads to higher rates of DNA damage within the sperm itself;
"When dietary AA was decreased from 250 to 5 mg/day, the seminal fluid AA decreased by half and the level of oxo8dG in sperm DNA increased 91%."
And this study further confirms that low levels of vitamin C appears to correlate with poor sperm morphology;
"Seminal AA in fertile and infertile (smokers or nonsmokers) males correlated significantly with the percentage of spermatozoa with normal morphology (p<0.01). Seminal AA decreased significantly in infertile men. Decrease of seminal plasma AA is a risk factor for low normal morphology of spermatozoa and idiopathic male infertility"
So I've immediately purchased some chewable vitamin C (500mg) tabs for my ever growing collection of supplements, I'm also going to add more citrus fruits to the diet... Aside from the odd glass of orange juice, this is something that admittedly has been almost totally absent for many, many years now.
