"Was it these or luck? I don't know. I know I was spending more than $200 a month on nine bottles before, this was one, and the retest went from 4.2 to 16.1. Not arguing with it."
SPERMFUEL+ is a daily male fertility formula built around the three numbers on a semen analysis: count, motility and morphology, for a better shot at pregnancy.
Each serving is two capsules with 14 fertility nutrients: 200mg CoQ10 and 440mg Carnitine absorbed with Black Pepper™, 30mg zinc, 200mcg selenium, methylfolate, methylcobalamin and 4,000 IU vitamin D, plus KSM-66 ashwagandha, tongkat ali and boron. Every dose printed, no hidden blends. It's the stack men assemble from nine separate bottles, in one.
Two with breakfast, every day, for one full 74-day sperm cycle. Then retest. Third-party tested.
14 fertility nutrients. Every dose on the label. No proprietary blend.
Minerals
Zinc, 30 mgZinc citrate. The top dose any fertility formula carries.
Selenium, 200 mcgL-selenomethionine. Protects sperm DNA from fragmentation.
Boron, 10 mgSupports healthy testosterone. Not one of the 17 top fertility formulas has it.
Swimmer Fuel & Healthy T
CoQ10, 200 mgUbiquinone. Powers every swimmer. The dose the studies used.
Acetyl-L-Carnitine, 440 mgCarries fuel into the swimmer's engine. More than any other 2-capsule formula we checked.
Black Pepper Extract, 5 mg95% piperine. Helps your body absorb CoQ10 and Carnitine.
KSM-66 Ashwagandha, 200 mgPatented extract. Cortisol management for hormonal balance.
Tongkat Ali (10:1), 50 mgEqual to 500 mg of root. Free testosterone support within normal range.
Vitamins
Vitamin C, 60 mgAscorbic acid. Frontline antioxidant protecting sperm DNA.
Vitamin D, 4,000 IUCholecalciferol. Ten times what FertilAid puts in theirs.
Vitamin E, 30 mgd-Alpha tocopheryl succinate. Fat-soluble shield for the sperm membrane.
Vitamin B6, 8.5 mgPyridoxal-5'-phosphate. The active form. Hormone regulation and amino acid metabolism.
Folate, 800 mcg DFEMethylfolate. The active form. Not the folic acid that failed the JAMA trial.
Vitamin B12, 48 mcgMethylcobalamin. Not cyanocobalamin. DNA synthesis during sperm development.
Beef gelatin capsule. Gluten, wheat and dairy free. Third-party tested. Non-GMO. Other ingredients: magnesium stearate.
Two capsules a day with food and a full glass of water. That is the full serving. One bottle is one month.
Judge it at 90 days, not 10. Sperm take roughly 74 days to develop. Nothing you take today shows on a semen analysis for about three months. That is not marketing, that is biology.
120 day retest guarantee. Run the full protocol. If it is not for you at any point, contact us for a full refund. Every penny back. Not because we are generous. Because we know what this does and what it does not.

"My advice to every man with a bad result is the same: 90 days on this before we do anything invasive. Most of them come back with better numbers. Most of them come back pregnant. In my experience it's the most potent formula on the market, so it's the first thing we try."

What Our Customers Say
Why couples who were told to just keep trying take two capsules with breakfast instead
"We got the call on a Tuesday." His count was sitting at 2.1 million when we started. Our RE said anything under 15 was going to be tough. Three months of these with breakfast and the repeat came back at 19 million. The nurse read it twice. We are 28 weeks now and I still have the lab printout on the fridge.
"My wife ordered them. I took them to shut her up." Did not read the label, did not look at the page, did not care. Ninety days later my urologist pulled up the new SA and asked what I changed. Motility went from 28% to 51%. I had to text my wife the name because I genuinely did not know what I was taking.
"Honestly not sure if it was this or the other stuff. We also cut the beers, switched to boxers, started sleeping properly. So I can't tell you which one did it. What I can tell you is the retest came back better on all three numbers, so something worked. Only complaint is shipping, took 6 business days to reach us."
"Our doctor said IVF was the only path left." That conversation costs $200 and the treatment costs $15,000. I asked for 90 days first. Took these every morning, stopped the nightly beers, switched to boxers. Went back for the repeat and my count had tripled. We conceived naturally two cycles later. I think about that $15,000 often.
"Morphology at 1% is not a number anyone wants to hear." Our RE circled it on the report and said it was the main problem. Three months of these plus cold showers and keeping the laptop off his lap. Came back at 4%. She said that was enough to work with. Our son was born in March and he has his father's nose.
"I never write reviews for anything." Six years, three clinics, two failed IUIs and a conversation about donor sperm that I did not want to have. Started these in January. She had a positive in April. I sat in the car for ten minutes before I went back inside because I needed to be calm when I told her.

From The Bad Result
To The Retest
From The Bad
Result To The
Retest
Day 0
The numbers come back low. You sit in the car twenty minutes before you can drive. The doctor said keep them cool and try IVF. By 2am you're on Reddit, reading other men's results, with six bottles in a cart.
Two capsules with breakfast. One bottle instead of twelve. The nutrient debt starts getting paid back today. Every sperm on your next analysis starts building now.
Day 1
Day 30
Nothing to measure yet, and nobody warns you about that. The sperm showing up now were made before you changed anything. The debt is being refilled where you can't see it yet. Don't retest. Don't panic. Biology is finishing what it started.
The first batch built on the full formula is maturing. Sixty days of 200mg CoQ10 and 440mg Carnitine absorbed with Black Pepper™, plus zinc and selenium, behind every one of them. Two weeks to go.
Day 60
Day 74
The 74-Day Swimmer Rebuild System™ is done. One full cycle, built on a full tank. Book the retest. Same clinic, same cup, same awkward room. This time you're not scared of the number.
Both printouts side by side. The urologist says keep doing what you're doing. Your wife stops researching clinics. And the side effects nobody warned you about? More drive, more energy, bigger loads. Trying stops feeling like a chore and starts being fun again.

Trying for 10 months. Low sperm count. Took these about 40 days and got a positive test. Honestly can't say if it was the pills or just our month, but I'm not questioning it.

FAQ
Commonly Asked Questions
I already tried supplements for months and my numbers did not move. +
Usually it comes down to two things. The dose and the timing. Most fertility bottles carry 100mg of CoQ10 or less, often hidden inside a "blend." That is too little to pay back what every try spends. This label prints every dose, starting with 200mg of CoQ10, the dose the studies used. And sperm take about 74 days to build. Test before that and you are measuring sperm made before you started. Most men quit right before the batch that counts.
I've never been tested. Do I need a semen analysis first? +
No. Most men who start here have never been tested. A test is a snapshot. It tells you the number, not why it is low. You can start today and test at day 90, when the new batch is built. If you want a baseline, an at-home test works fine. Test now, start the capsules, retest at 90 days. Either way, the 120-day guarantee covers the full cycle.
We've been trying for 2+ years. Is it too late? +
No. Your body does not keep the old swimmers. It builds a brand-new batch every 74 days. That means the batch that counts has not been made yet. Two years of trying drained what your swimmers are built from. That is fertility nutrient debt, not a dead end. Two capsules a day pays it back, and 90 days from now you are testing a whole new batch.
My wife read that supplements are a waste of money for fertility. +
She is probably thinking of the JAMA trial. That study tested synthetic folic acid on men and found no benefit. That is our point, not hers. The synthetic form failed. This label uses methylfolate, the form the body does not have to convert. The 90-day retest settles it either way, and the guarantee covers the full cycle.
Is 200mg of CoQ10 actually enough? +
It is the dose the studies actually used, 200 to 300mg. It is the same 200mg SwimClub sells in a $135 pack of 7 pills a day. Here it is 2 capsules. It is 2X Eu Natural's 100mg, and FertilAid will not even print its number. And it does not work alone. It is part of our 74-Day Swimmer Rebuild System™: 440mg of Carnitine works right beside it as the engine, and Black Pepper™ helps your body absorb both. You already know turmeric does little without black pepper. Same principle, same panel.
Is there carnitine and NAC in here? Those are the two everyone recommends. +
Carnitine, yes. 440mg of acetyl-L-carnitine, more than any other 2-capsule fertility formula we checked. It carries fuel into the swimmer's engine, right next to the 200mg of CoQ10. NAC is not in here. A real NAC dose is 600mg on its own, and we chose to keep this to two capsules with every dose printed instead of cramming in decoration doses. If you want NAC on top, add it. They do not compete.
Will the ashwagandha thicken my semen and hurt my motility? +
That report came from a man taking KSM-66 at 675mg, the full standalone trial dose. This label has 200mg of KSM-66, less than a third of that, printed right on the panel. It is there for count and testosterone, next to the CoQ10 and carnitine that drive motility. Your 90-day retest will show you exactly where motility stands.
My doctor said there is nothing I can do and to try IVF. +
He is following the current guideline, and it is based partly on the same JAMA trial that tested synthetic folic acid and zinc and found no result. That study did not test methylfolate, CoQ10, carnitine or selenium. IVF picks the best of what you hand in. It does not build a single new swimmer. Your body builds a brand-new batch every 74 days, and that is exactly what the 74-Day Swimmer Rebuild System™ is built for. Give it one full cycle before you sign a $12,000+ IVF bill. Then retest. If your numbers do not move, the 120-day guarantee pays you back.
My doctor wants me on Clomid or HCG. Should I try this first? +
Most men do. Clomid and HCG push your body to make more. They do not give it anything new to build with. If what your swimmers are built from is missing, pushing harder just drains the account faster. Give it one full 74-day cycle of two capsules first. No script, no shots. Then retest. If your numbers do not move, the 120-day guarantee pays you back, and the script will still be there.
How do I know the reviews are real? +
The real proof in this category is not a review card. It is two semen analyses side by side, posted by a man who has no reason to lie. That is what the community trusts, and that is exactly what the 90-day protocol is built for. You will hold your own baseline and your own retest. Your numbers are the demo.
This is just a multivitamin with a fertility label on it. +
A multivitamin does not carry 200mg of CoQ10, 440mg of carnitine, KSM-66 ashwagandha or tongkat ali. It usually uses folic acid and cyanocobalamin. This uses methylfolate and methylcobalamin, selenium as selenomethionine at 200mcg, and vitamin D at 4,000 IU. The panel looks similar until you read the doses. That is the whole point.
I read that the pills smell terrible. +
B vitamins and selenium have a strong natural scent. That is what potency smells like. Two capsules with food and a glass of water and you are done in ten seconds. The alternative is four gummies that taste like candy and skip the ingredients that matter.
