Omega 3

Having moved on from researching anti-oxidants, I'm now looking at everything and anything else which could improve my sperm morphology, and honestly, its slim pickings.

The only thing i can find which isn't an antioxidant, is Omega 3.

There are a few studies out there which investigate the impact of Omega 3 on sperm morphology, this one is perhaps the most interesting, it essentially analysed Omega 3 intake for 99 men and compared various sperm parameters, it found;

"intake of omega-3 polyunsaturated fatty acids (PUFAs) was associated with higher normal sperm morphology. Men in the highest tertile of omega-3 fatty acid intake had a 2.2 (95% CI: 0.7 to 3.4) higher percentage of morphologically normal sperm than men in the lowest tertile of intake."

Here's the table with the stats, the higher the Omega 3 intake as a % of your diet, the higher the sperm morphology;

This is a minor improvement, but I'm looking for all the help i can get, so Omega 3 makes the (now completely full) supplement list!

Next up I'm going to look into acupuncture a little more as there appears to be a few studies out there which suggest it can have a positive impact on sperm morphology.

Semenax and Sperm

After much deliberation, I've decided a product known as Semenax makes the list of supplements.

In my quest to improve my sperm morphology, I have been almost constantly bombarded by advertisements for various 'libido enhancers' all 'scientifically proven' to improve my sex life (I guess after searching for 'how to improve sperm morphology' over 50 times, google tries its best to help out).

So after exhausting pretty much every scientific paper i can find about sperm morphology, I started to look elsewhere, and Semenax is one of many products out there that claims to improve my libido (and sex life among other things).

To cut to the chase, there are a lot of trash products out there, i read up on at least 20 similar 'fertility' and 'male enhancement' products and they were all garbage with no scientific evidence to support their claims.

One of the few products which actually supported some of their claims was Semenax.

The unique selling point of Semenax is that it appears to increase the volume of your semen, by increasing the amount of seminal fluid produced by the body. Semenax has a huge amount of ingredients, so they appear to taking a kitchen sink approach to their product;

Their website gives more details on the effect of all these ingredients, and there is a lot of good stuff in there which ties up with a lot of the research I've conducted over the last few months; Arginine, Zinc, Carnitine, Vitamin E, Pine Bark Extract (Pycnogenol) have all been proven to improve sperm quality.

But the main reason i went with Semenax is because they have actually produced a scientific paper, they tested the product on 60 people and the results actually showed a marginal improvement in sperm morphology;

Though I don't fully understand the ANOVA measurement style, the key thing in my mind is that the morphology numbers improved!

So Semenax makes the list, if this improvement in morphology was down to the antioxidants included in the product, then great. If its down to some of the other ingredients, then I've now got that covered too.

Pycnogenol - The last antioxidant

Pycnogenol is the last of the major antioxidants i think can help improve my Sperm morphology. It also appears to be one of the most powerful antioxidants available.

This paper, details some amazing improvements in sperm morphology - 19 people took 200mg of Pycnogenol a day for 3 months, and this was result;

"...Pycnogenol produced a 38% improvement in sperm morphology "

38% improvement!! That's huge!!

But there's more good news about Pycnogenol, this site concludes that when combined with COQ10, the power of both antioxidants is actually increased;

"The antioxidant effect of both micronutrients together was higher than expected from their respective individual activities, proving that CoQ10 and Pycnogenol cooperate synergistically for maintaining good cardiovascular health."

So Pycnogenol makes the list of antioxidant supplements.

Next up I'm going to look into other supplements which may improve morphology as my research into antioxidants has pretty much dried up!

What causes Teratozoospermia (Part 2)

The more I read up about Teratozoospermia (and not just Teratozoospermia, but male infertility in general), the more i am convinced that Oxidative Stress plays a huge role.

The building blocks behind healthy sperm are quite simple; maintain a healthy weight, exercise regularly (but not to excess), avoid stress and eat a healthy diet of protein, fruit and vegetables. This alone should give a man everything they need to create healthy sperm well into their 40's and 50's. Simple.

But for whatever reason, in some males, there appears to be something happening which impedes the healthy formation of sperm. For a healthy man to have 0% morphology at 33 years old is quite unusual, there must be something else at play, something which is constantly nuking the production process.... And almost every study out there seems to think its Oxidative stress.

There are a few things that (i think) I've come to understand over the last few months which could be impacting me;

1) Oxidative Stress on the testicles is something that can build up over time; The major culprits appear to be

• Alcohol 
• Poor diet
• Excessive heat (in fact i read in some cultures people use excessive heat to sterilise themselves!)

These things cause oxidative stress, which leads to poor sperm morphology.

But there's another source of Oxidative stress, and that's;

• Defective Sperm themselves - They essentially fall to pieces and in doing so, actually cause Oxidative Stress to the other healthy sperm.

So......

More Oxidative Stress means more Defective Sperm
More Defective Sperm leads to more Oxidative Stress

Its a vicious cycle which if left unchecked could totally trash the quality of your sperm.

This article provides a good overview of all things that can impact on sperm quality, it summarises;

"Spermatozoa are vulnerable to ROS (oxidative stress) because their plasma membrane and cytoplasm contain large amounts of polyunsaturated fatty acids.5 Excessive generation of ROS in semen by leukocytes as well as by abnormal spermatozoa could be a cause of infertility."

I think its possible my intake of antioxidants has been so low over the last few years that the build up of Oxidative Stress has pushed my sperm into this vicious cycle from which it cannot escape on its own..

2) Each cell in the body is under constant attack from Free radicals;

"Bruce Ames, a well-known scientist in the field of antioxidants, estimates that just one cell in the human body is hit about 10,000 times a day by a free radical. If that’s multiplied by the trillions of cells in the body the magnitude of this activity is tremendous."

10,000 times per day for each cell! That truly is huge, the one glass of orange juice a week i had on my old diet really wasn't enough to fight this barrage, so its no wonder my sperm production process has fallen into this vicious cycle. 

The 'cure' to all of this definitely appears to be a huge and ongoing dose of a variety of antioxidants, this should be enough to pull the sperm production process out of this funk and get things back on track. Time will tell, the next sperm test is only a few months away!

Selenium (AKA Brazil Nuts)

I'm now taking so many supplements that I'm starting to rattle, however the research continues and the latest discovery relates to Selenium. And it appears as though the jury is out.

When i received by sperm analysis results, the doctor suggested i should eat some brazil nuts and drink green tea, at the time i thanked him for his advice but in my head i was thinking 'no way that's going to make any difference'. Regardless, i started eating the brazil nuts, about a handful a day.

Brazil nuts are apparently extremely high in Selenium, which appears to be very important to the formation of sperm;

"..Selenium protects lipid shell encasing each sperm (prevents lipid peroxidation), which is especially important since sperm have a very delicate fatty acid composition."

Essentially it helps protect the sperm from free radicals.

According to the below supplement sheet, 6 large brazil nuts can contain a whole load of useful nutrients including Vitamin E, Zinc & Magnesium, but most importantly, they contain about 800% of the RDA for Selenium;

That's an extremely high dose of selenium for just 6 brazil nuts, so how many should i be eating exactly?

Well, it seems that nobody really knows for sure. Too little and there's no impact, too much and it can have a negative impact;

A study into a dose of just 0.2mg of Selenium combined with n-acetyl-cysteine (another antioxidant i haven't yet looked into) had a good result;

"after 26 weeks of Se supplementation the mean total sperm count, concentration, normal morphology percentage and motility increased from baseline relative to placebo treatment"

Good stuff, so how about a higher dose?

A study into a dose of 0.3mg Selenium alone had this to say;

"higher Se supplementation (300μg/ day orally) increased serum and seminal plasma Se concentrations but did not affect sperm Se, serum androgen concentrations or sperm parameters [22]. The lack of an increase in sperm Se suggests that testicular Se stores are unresponsive to dietary Se concentrations"

...No major impact. Ok so how about even higher?

This study tried a volume greater than 0.4mg and had this result;

"The fraction of motile sperm in the high-selenium group decreased by 32% by week 13 and ended 18% lower than baseline. Selenium concentrations changed in seminal plasma but not in sperm"

So it appears as though a high dose is a no-go. The studies show an increase in Selenium within the seminal plasma, but not the sperm itself... This suggests to me that the spermies just don't require that much selenium.

This summary sheet provides a good overview of the various Selenium studies out there, it essentially concludes that selenium is most effective at a low dose and combined with antioxidants, particularly vitamin E (which is also present in Brazil nuts).

So exactly how many brazil nuts should i be eating? This website suggests 6-8 brazil nuts can contain about 0.5mg of selenium. I need about half of that apparently, so from now on I'm going to eat just 3 brazil nuts a day for my selenium fix.

L-Carnitine

So it appears as though this one is a biggy.

There are a lot of studies out there into L-Carnitine and as far as i can see, all of them conclude the same thing, that L-Carnitine not only has antioxidant properties, but also plays a crucial (yet poorly understood) role in the formation of sperm (as far as i can tell, it appears to be primarily related to sperm motility / energy).

One study simply conducted a test into the levels of Carnitine found in the sperm of fertile & non fertile men, and they found a significantly higher amount of Carnitine in the fertile samples;

"The level of free L-carnitine in the seminal plasma of the fertile men was significantly higher than that of the infertile (P < 0.01). The lower the sperm concentration, the weaker the sperm vitality, the more significant the difference"

After searching for 'sources of carnitine', i found that its most commonly found in red meats like Beef and pork, neither of which i consume on a regular basis, so it follows that i might have low levels of Carnitine in my system which could be contributing to my poor sperm morphology.

One study had this result with 1500mg of L-Carnitine mixed with various antioxidants;

"Semen analysis data showed a significant increase in concentration, motility, vitality and morphology parameters"

But its this study which i found particularly interesting, it gave 156 people 1000mg of Carnitine a day for 3 months, and this was the result;

A significant uptick in all parameters, but its greatest impact was on morphology, so this one seems like a no brainer, its definitely something i need to add to the collection.

Vitamin C

Vitamin C (aka Ascorbic acid), i had no idea how important it was.

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.
