Fish Oil and Testosterone
Many, perhaps most, of the what I call the Super Cultures (in terms of health and
longevity) eat fish as a staple. I covered in another link
Protects Your Heart (and Therefore Penis). But did you know that Fish
is extremely protective of your testosterone as well? That's right - no
other supplement that I know works in so many ways at protecting your testosterone. You
could rightly call Fish Oil Anti-Andropause.
First of all, fish oil has many studies showing that it combats insulin
resistance. Insulin resistance, as you hopefully know from my link on
Metabolic Disorder, is the hallmark sign of
Metabolic Disorder and
Metabolic Disorder is associated with decreased testosterone (and erectile dysfunction).
The reason is that fish oil has long chain omega-3 fatty acids, which improve

In fact, fish oil can protect you from the insulin resistance that is brought
about a high fat diet or saturated fats.  This is one of the big problems
with modern cattle and pork: they are very fatty (25-35%) versus their
wild game equivalents (~4%) and, even worse, their fat has very little omega-3's
because they are grain fed not grass fed. In other words, their muscle
ends up extremely fatty and laced with insulin resistance-inducing saturated
fats. And then, as if to add insult to injury, ranchers make sure that the
one ingredient, omega-3's, that could take care of the insulin resistance are
One recent study shows that taking fish oil capsules
dramatically increases the risk for advanced prostate cancer - this is the kind you don't want! - and significantly
increases it for all prostate cancers. See this
article for more details.
Based on this, the authors recommended eating just one or two meals of fish per week instead. Keep in mind that this is
just one study, but the results were so pronounced that it should be carefully considered. For a nice rebuttal to this study,
discussion for more information.
Protecting your testosterone from insulin resistance is just the beginning.
Fish oil has also been shown to lower SHBG.  Again, this is anti-andropause
because andropause is known for slowly raising SHBG levels with age, which means
that more SHBG is bound to your testosterone leaving you less free
testosterone.. The net effect of taking fish oil, then, is the opposite
and will leave you with more free testosterone.
Fish Oil has also been shown in one study to increase Luteinizing Hormone (LH).
Luteinizing Hormone (LH), you may remember from other threads, is the hormone
that triggers or signals testosterone production. It is particularly
strong in young males, but is important for us old guys as well.
So, again, fish oil is definitely not a panacea to solve your low testosterone
problems. But it likely will boost your free and total
testosterone a little and preserve your total testosterone from the ravages of
andropause. When you consider what fish oil does for the brain, the heart
and your penis, it is a supplement well-worth the money in my opinion.

If you do decide to take fish oil, please read my link on
The Triglyceride versus Ethyl
Ester Forms of Fish Oil. Rancidification of fish oil is a significant issue and
this link discusses that in detail. You can do more harm than good if
you're not careful.
NOTE: Some have argued that fish oils are oxidative upon digestion
and that fish oil thus probably does significant aging and cellular damage
internally that we may not yet understand. However, several studies
suggest this to be a relative non-issue.  In addition, one study also
found that additional Vitamin E can protective help overcome most of the small
amount of oxidative damage that is done anyway. The study authors found
that oxidative products in the urine "more than doubled when the fish oil
capsules were introduced but then dropped by a factor of four when vitamin E was
added. The vitamin E concentration in the red blood cells dropped very
significantly when fish oil was ingested but more than recovered with the
vitamin E supplement". 
Also, I recommend that you take a mixed tocopherol blend of Vitamin E, rather
than the standard alpha tocopherol Vitamin E used in this study, even though it
is more expensive. Pure alpha tocopherol can lower your body's other
