I’ve eliminated all foods that I thought could be contributing to this but never thought of the fish oil.

Just an update. It’s been 3 days since I cut out the fish oil and my libido is back with a bang, horny as hell again thank god.
I cant believe how suppressive that stuff was for me. My thoughts are that the fish oil I was using (It was not Biotest’s stuff) may have had a high content of PCBs and contaminants, perhaps negatively influencing testosterone? Who knows.
All I know is that I wont be using it again.[/quote]

What brand did you use?

I used “Seven Seas”

I haven’t taken fish oil since last Friday and I have noticed libido and pole rigidity coming back to normal. I am going to be cutting my fish oil amounts way down.

This very thing has had me so concerned that I joined this website. I don’t train as a body builder, but I do exercise. On or about October 16th, I started taking–I’m embarrassed to admit–15g of fish oil a day. Very slowly, my libido DIED. DEAD. Porn is like watching a nature show. My girlfriend–brilliant, beautiful, built–started to look about as appealing as a sofa.

AND, no “pole”, as you guys put it. So I started thinking: could it be the fish oil? Thank God I found this thread. By the way, my sex drive before this was ANIMALISTIC.

Here’s my question: for you guys who went through this, how long does it take for things to get back to normal? I hope the damage isn’t permanent. This is day four off the fish oil.

I’m going through this…I could find next to nothing on the internet about this. Thank God for this website and forum. For those of you who experienced it and stopped the fish oil: how long did it take to recover?

This is day four off of fish oil after almost a month of megadosing on fish oil.

I think the problem here is too much of a good thing. It’s like a teenager and the “well it says to take 5 a day, so I’ll take 10 a day and get double the results”. We all know this isn’t the case with supps.

I take 5 grams of fish oil (Now 500 DHA) every other day and 6 grams of flax oil the other days. Besides those, vit d3, zma and whey isolate I don’t take shit.

FTR my drive is that of a 13 yo in a porn store.

Everything in moderation people.

It’s really well over my head, but you might just need more cholesterol in your diet. Omega 3’s modulate cholesterol trafficking which affects steroidogenesis. Perhaps a lack of substrate (cholesterol) combined with that (very high) dose of omega 3s created a situation where your cells were trying to increase steroidogenesis but the materials just weren’t there.

…That or just back off the dose. Also, if something happened like this it’s going to be hard to say how long it will take to “recover” because perhaps the lipid structure of your cells has changed.

Browsing applicable journals might shed some light on this: i.e. Do polyunsaturated fatty acids stimulate steroidogenesis through affecting the expression of liver X receptor? | SFEBES2008 | Society for Endocrinology BES 2008 | Endocrine Abstracts

Wow, it’s crazy to see this thread living 5 years later after I started it! I actually forgot that I opened a discussion on this topic back then. Some of the threadsâ?? readers may be interested in my personal experience in the years following thread creation… so I will share.

The final verdict (for me) is that consistent fish oil intake has a significant impact on my libido. While I don’t remember the exact number of times I performed the fish oil experiment, it was somewhere in the neighborhood of 10-15 times over the last 5 years. In fact I just completed the most recent one today. Every repetition of the experiment was Fish Oil only with the exception of the most recent one. On the Fish Oil front, I have only taken Flameout since it was released by Biotest (forgot the year). Back in the timeframe of starting this thread, I tried a few different brands. For the Flameout only versions of the experiment, I typically dosed at 2 capsules twice a day for a total of 4 caps. In the earlier days, I took a little moreâ?¦ but not much more.

When beginning a new experiment repetition, I usually didn’t notice too much of an impact until day 4 or 5, which is when my morning wood typically began to fade. By the end of the second week I am completely disinterested in sex; whether it be indifference to a shockingly hot girl walking in front of me in tight pants or ignoring the attractive girl waiting for me in my own bed… lack of interest is the outcome. Frequency and intensity of erections are by far the most noticeable symptom, everything else is purely subjective… albeit very noticeable.

I report all of this with great sadness. It is a very sad truth for me and the only reason I repeated the experiment so many times is because I wanted it to turn out differently each time due to some of the benefits I enjoy from fish oil. While it doesn’t do much for my joints… damn does it do wonders for my skin! My complexion is damn near perfect after a week or so of taking it. I do feel a tad sharper mentally when taking it as well.

For what it’s worth, I experimented with many types of diets while performing the various experiments to see if it would help. In the end, I only marginally stemmed the libido reduction with dietary changes. A massive bulking diet complete with all sorts of extra cholesterol had a very minor hedging effect, but it was minor. Every other dietary mix proved insignificant and the libido loss was the same. These various experiments also occurred during periods of time that covered just about all levels of stress, sleep health and overall health. So I canâ??t blame any of those external factors.

This most recent experiment (2 months in total) was a little different than the others and gave me the most significant libido shut down to date. I decided to introduce Krill Oil into the mix. I took 2 Mercola Krill Oil capules with breakfast, 2 Flameout capsules with lunch and 2 Flameout capsules with dinner. The libido shutdown was complete by day 5. After the 2nd week, I went down to 2 Flameouts from 4… but there was not even a slight increase in libido after 3 weeks of that. The last 3 weeks I went down to just the 2 Krill Oil capsules in the morning with breakfast. I did notice a minor increase in libido after a week or so of doing this, but it was only back to a level that is still low by my normal standards.

About me, I am approximately 185lbs these days and 8% bodyfat. I have been very close to this composition for the past year. In past years, I think I was generally between 190-195lbs and 10-14% bodyfat. I ran the fish oil experiment twice in the past year and while the most recent was the most significant impact, the previous one was fairly significant too relative to previous repetitions. In retrospect, I am wondering if the previous posterâ??s statements about bodyfat hold water with me too. I have always been fairly lean on account of my natural tendencies, but I am a bit leaner these days that Iâ??ve been before. That said, I am in no way dieting or cutting calories in any way. I have been on a maintenance diet for about 8 months. I am probably forgetting a bunch of interesting observations because I am condensing years of stuff into one post, but this is a decent summary.

Is there any effect on the latter from the former?

Up until a month ago, 90% of my efa’s came from flax oil, olive oil, natty pb, and omega eggs. I have since added fish oil caps to the regimen, NOW SUPER EPA to be exact. After a week of steady use, I began to notice a steady decline in my ‘interest’. All the equipment still functions properly (albeit less frequently), but the drive has been lacking. I didn’t immediately think anything of it until the drive loss continued for more than a week. This is when I began suspecting a potential fish oil connection since nothing else has materially changed in my diet, sleep, or workout patterns… is this a coincidence or a possible connection?[/quote]

Thought of a few other interesting items as I was eating:

  1. During the first week or two of restarting fish oil consumption, there is a positive mirror effect of looking harder and improved definition. Since I typically drop a few pounds during this phase too, my unscientific assumption is that I don’t hold as much water when taking fish oil.

  2. I am not much of drinker, both in frequency and in volume. On the few occasions that had a few cocktails during the fish oil experiments, my morning wood would return the morning after the drinks were consumed. Then it would go back on sabbatical by the next day.

*both 1 & 2 lead me to think there is an estrogen connection to this fish oil phenomenon

  1. I am thinking this whole phenomenon is more rooted in individual’s hormonal feedback loops & balances. While low bodyfat may exacerbate the fish oil induced libido loss in individuals prone to it… I don’t think it is the main factor. I imagine there are plenty of ultra-lean people mega dosing fish oil with zero impact on their libido. Unfortunately, just regular dosing affects me.

  2. My next round with fish oil will be designed to find a dosing regimen that keeps my skin mostly clear, but maintains my libido to near normal. I may start off doing a 1 day on and 3 dyas off or something like that.

how old are you ? and like chi town said low bf does have an affect on labido .
ive drank fish oil nearlly all my life and never had a problem , in the last 20 years alot a day , i dont measure it just swig it from the bottle.
my labido and interest dropped a bit when i reached 40 (im 43 now ) i take trib now 650mg twice a day one pre w/o the other in the evening .
it really helped me got me back on form to about the same as when i was in my late 20’s

here is the evidence that you need estrogen for libido.
estrogen is not bad, it is essential for males.

DHA from fish oil seems to wack ERalpha.
study: Docosahexaenoic acid induces proteasome-dependent degradation of estrogen receptor alpha and inhibits the downstream signaling target in MCF-7 breast cancer cells - PubMed

Mice need estrogen receptors for Sexual Agression (libido)
study: http://www.jstor.org/pss/2666365
fun to read actually :slight_smile: our small brains are just like theirs…

Phytoestrogens are weak plant estrogens that interfere with the estrogen receptor, that is still available.
But this is the downside, all those plant chemicals seem to inhibit AROMATASE enzyme.
think about this, why would a plant have chemicals that inhibit aromatase?

for it’s survival from omnivores?
when you realise that estrogen is a vital hormone for reproduction in animals,
then all those plant eating animals (they have to eat LOTS of leaves for their calories) and their hormone production gets imbalanced and they can not reproduce which helps surival of the plant species.
(that was just a thought tho)[/quote]

The steroid structure is common throughout nature. Anabolic steroids are based on cholesterol. Cholesterol itself even has some of the same effects that sex horones have on mammals. The sex hormone pathway is almost universal throughout the mammalian kingdom. Even invertebrates have signal molecules with structures similar to testosterone.

Just because something in nature has an effect, it doesn’t mean it evolved to have that effect. Evolution is messy. Cause =/= effect.

how old are you guys having problems with gettin it up ? . im 43 n didnt start getting a drop in action till i hit 40 . ive drank fish oil all my life . for the past 20 years ive drank alot, just swig it from the bottle a few times a day ( probably about 15/20g ).
for the labido problem i started taking tribulus 3 years ago( 650 mg 2x a day ).this got me back on form similar to when i was in my late 20’s .
also what chi town said about low bf , i read somewhere that has an affect on sex drive n testosterone.

I am 33. The thing about bodyfat % is that the libido decrease I am talking about occurs when taking fish oil and the low libido returns to normal after fish oil cessation. This phenomenon occurs at all bodyfat levels for me. Clearly this is not a common effect, but it doesn’t seem like it’s entirely uncommon either judging by some of the other participants in this thread. When I started this thread 5 years ago, I thought I was crazy because I had not heard or read of this anywhere. However, what I was experiencing and experienced many times over since then, is very real. If I had more time, I would do exhaustive blood work on all the relevant hormone markers before, during & after fish oil supplementation to see what is going on inside and then cross-reference that to daily observations. If I was younger and didn’t work/travel all the time, this would be a possibility. Perhaps someone will look further into this one day.

Well polyunsaturated fatty acids REDUCE testosterone levels while MUFA and SFA increase test levels. Also one of the reasons that eating chocolate and green tea in excess ect also lowers test because test relys on OXIDATION and excess antioxidants get in the way. Studies have shown green tea and PUFA lowers test. with all the hype around omega 3’s no one looks at the negatives and they are there for sure.

Listen buddy.
Just find some better porn. I take 10 grams of fish oil a day, and am about 8 percent body fat and I have no probs in that department.

tweet tweet

I had been taking about 6 grams daily for about 2 years and had been having the same issues. Nothing would work unless I had some cialis or viagra. Docs chalked it up to stress since blood levels were good after tweaking my E2.

After recently reading the OP, I stopped with the fish oil caps and after about 1 1/2 weeks the little man is waking up and showing spontaneous signs of life. Not sure what the connection is, but I am almost ready to say i agree with him. For some reason stopping daily dosing of fish oil has done what it took the little blue pill to do for over a year.

After all this time, the culprit–in my case–has been found. Follow closely, because it’s weird.

I train hardest during the spring and summer, and move inside during the snowy season. Weights. Treadmill. Etc.

Because I’m hitting weights harder, I have traditionally upped my dose of fish oil between October and February. And, right around the same time I move inside, my libido disappears. happened 2009. 2010. 2011.

So I finally find an endocrinologist. My T is not only normal, but “very high.” My Free T is in in mid to upper 20s.

But here’s where it gets weird. I’m originally from the deep south, and these symptoms started when I moved to Minnesota in 2009.

I don’t have testosterone problems, and it isn’t fish oil. It’s WINTER DEPRESSION! The doctor prescribed me a light to sit in front of and some low-level anti-depressants and my sex drive is ROARING back!

So don’t rule out depression, even if you don’t “feel” sad. I never did. Your BODY can feel stuff that your mind can’t.

You can probably ditch the antidepressants. Up the vitamin D3.

Gonna go with Dwarf on this one. Multiple studies have been done that show…Low D3 can cause depression. Either try finding a way to get some sun or dose up on some D3. Worth a shot!
