Fertility Factor 5 Review 2026: What Its Five Ingredients Show

Introduction: What This Review Covers

Leading Edge Health sells this male fertility supplement. The ingredients on our earlier page were wrong: we listed zinc citrate, selenium, ashwagandha, folic acid and CoQ10. The official formula is LJ100 Tongkat Ali extract, Panax ginseng, zinc, selenium and BioPerine, and that's what we cover here, along with the ingredient research and the kind of man it may suit.

We start with today's label and whichever doses it discloses, then ask if the finished product has a published trial. After that come ingredient research, guarantee conditions and the safety points that matter most. We summarize three other men's products from our reviews too, none of them built for fertility: Testosil is a testosterone support formula, Semenax targets semen volume and VigRX Nitric Oxide is an erection product. Purchases through our links earn us affiliate commissions, as disclosed above.

Where we land on Fertility Factor 5

Fertility Factor 5 may suit men trying to conceive who want a Tongkat Ali, selenium and zinc supplement alongside a medical fertility workup, not in place of one. The product itself has never been tested, and the best study of its main ingredient had no placebo group.

How to Judge Products in This Category

Before getting into the details, run through these checks first:

• Doses versus the research: An ingredient present at a small fraction of the studied dose is unlikely to match the findings. See whether the label discloses every dose, then compare each with the amounts used in human studies.
• Human evidence: Look for a published, placebo-controlled trial of the product itself. Most products in this category have none. They lean on ingredient studies, animal data or traditional use.
• Branded ingredients: Extracts with brand names are standardized, and some have their own studies, often funded by the supplier. A brand name by itself doesn't tell you the product uses a studied dose.
• Manufacturing and testing: In the US, supplements must be made under the FDA's current good manufacturing practice (cGMP) rules. A certificate of analysis from an independent lab is a helpful extra check on purity and dose.
• Refund terms: Read the conditions, not only the number of days. Many guarantees want containers back at the warehouse inside the window, and they don't refund shipping.

Fertility Factor 5: a closer look

67-Day Money-Back Guarantee (seller's terms apply) | Aimed at male fertility support

Leading Edge Health makes this five-ingredient male fertility supplement, which has LJ100 Tongkat Ali extract, Panax ginseng, zinc, selenium and BioPerine. Ingredient studies exist, but the product itself hasn't been tested.

Our Findings

• Formula: Five ingredients appear on the official formula page. They are LJ100 Tongkat Ali extract (about 200 mg a day), Panax ginseng, zinc, selenium (about 70 mcg a day) and BioPerine. Ginseng and zinc amounts aren't given in text. Ashwagandha, folic acid and CoQ10 aren't part of the formula.
• Evidence: No trial has tested Fertility Factor 5. Its main LJ100 study, with 75 men with unexplained infertility taking 200 mg a day, reported better semen measures but had no placebo group. In subfertile men, small placebo-controlled trials of selenium show better sperm motility. Evidence on zinc and ginseng is mixed.
• Guarantee: You have 67 days from delivery. Containers must be returned empty (unopened plus the first two opened count as refundable) and arrive inside the 67 days, "no exceptions". Shipping isn't refunded, and there's one refund per customer.
• Cautions: Tongkat Ali may change hormone levels, so people with prostate cancer or another hormone-sensitive condition should avoid it. Ginseng can interact with warfarin and diabetes medicines. This product is no substitute for a semen analysis and fertility workup.
• Pros: A short, focused formula that states key doses (LJ100, selenium); an LJ100 dose that matches the amount in its main study; some placebo-controlled evidence for selenium and sperm motility; a long-established seller with a written 67-day guarantee.
• Cons: Strong marketing claims aren't matched by a trial of the finished product; the main LJ100 fertility study lacked a placebo group; ginseng and zinc amounts aren't stated in text; and sperm changes need three months of use, longer than the 67-day refund window.

Semenax: a closer look

67-Day Money-Back Guarantee (seller's terms apply) | Top pick: semen-volume supplements

Leading Edge Health makes this 16-ingredient amino acid and herbal blend and markets it for semen volume. A small trial funded by the company found a modest volume increase compared with placebo.

A healthy man who'd like a modest increase in ejaculate volume, and is prepared to buy direct and watch the 67-day return window, may find Semenax a fit. Its single trial is small and company-funded, and it showed no clear benefit for men with low volume, sperm quality, erections or orgasm.

Our Findings

• Formula: The official ingredients page names 16 amino acids, herbs and nutrients but gives no amounts. They include Swedish flower pollen, L-arginine, L-lysine, zinc, L-carnitine, maca, pumpkin seed and Butea superba.
• Evidence: In one small, company-funded, placebo-controlled trial (2 months, 63 men analyzed, published 2022), ejaculate volume rose modestly compared with placebo. Men with low volume saw no clear benefit, and sperm count, motility and sexual function did not differ.
• Guarantee: A 60-day trial period applies, but you need to get empty containers to the warehouse within 67 days of delivery, "no exceptions". Shipping isn't refunded and refunds are limited to one per customer.
• Cautions: Nitrates, ED drugs and blood pressure medicines can interact with L-arginine. Buy direct, since counterfeits have been documented.

Testosil in Detail

Top pick: testosterone-support formulas | Lifetime Money-Back Guarantee (conditions apply)

Leading Edge Health makes this 4-capsule testosterone support formula. It is built on D-aspartic acid and KSM-66 ashwagandha (300 mg per serving), with zinc, vitamin D and botanicals added. Doses are disclosed, but the product itself has no clinical trial.

Testosil could suit a healthy man who wants a KSM-66 ashwagandha formula with every dose disclosed, a published lab certificate and a long refund window. Still, it has never been tested as a finished product and several doses fall short of the research. Its ashwagandha, zinc and vitamin D content also call for care with medications and other supplements.

Our Findings

• Formula: Each 4-capsule serving (figures from a 2023 batch certificate linked on the official site) contains D-aspartic acid 2,000 mg, KSM-66 ashwagandha 300 mg, L-arginine 250 mg, Panax ginseng 180 mg, fenugreek 50 mg, magnesium 50 mg, zinc 40 mg, vitamin D3 4,000 IU and smaller amounts of other ingredients. Every dose is disclosed.
• Evidence: Testosil itself has not been trialed. In one small 8-week trial of young men doing resistance training, KSM-66 at 600 mg a day (two servings) raised testosterone more than placebo (Wankhede et al., 2015). D-aspartic acid at 3 g a day did nothing to testosterone in trained men. Two servings would double zinc to 80 mg and vitamin D to 8,000 IU a day, twice the adult upper limits, so don't take two servings without a doctor's advice.
• Guarantee: It is advertised as a "lifetime" guarantee. The refund covers unopened bottles plus one opened bottle, shipping isn't refunded, and each customer can place one order. Some wording on the guarantee page is inconsistent, so check with customer service before you buy.
• Cautions: A single serving already reaches the adult upper limits for zinc and vitamin D. Ashwagandha has been linked to rare liver injury and can raise thyroid hormone levels.

VigRX Nitric Oxide: a closer look

67-day guarantee advertised (terms not confirmed) | Best for: a simple citrulline + arginine formula

A VigRX-brand capsule that combines L-citrulline and L-arginine. The body uses both amino acids to make nitric oxide. Doses aren't disclosed, and no clinical test of the product has been done.

This one is aimed at healthy men who want a product built on L-arginine and L-citrulline, two amino acids with some evidence at gram doses for mild erection problems. Its doses aren't disclosed, and no study has looked at the product. If you use nitrates, ED drugs or blood pressure medicines, speak to a doctor first.

Our Findings

• Formula: L-citrulline and L-arginine, according to a third-party review. Doses and serving size aren't disclosed.
• Evidence: No trial of the product exists. Some evidence supports L-arginine and L-citrulline for mild erection problems at gram-level doses, but without disclosed doses we can't tell if this product reaches them. It isn't a fertility product.
• Guarantee: A third-party review reports a 67-day money-back guarantee. We haven't verified the exact conditions.
• Cautions: With nitrates, ED drugs or blood pressure medicines, L-arginine can lower blood pressure further.

Buying Guide: What to Check

Before you buy any product in this category, check the following:

• Every ingredient and dose disclosed, with no proprietary blend hiding individual amounts
• Made under FDA cGMP rules, ideally backed by an independent certificate of analysis
• A refund window long enough for a fair trial, with conditions you've actually read
• Buy from the official site if you want the money-back guarantee to apply
• Marketing claims that stay realistic, with no promise to cure anything or guarantee an outcome

Safety Considerations

Every product discussed in this article is sold as a dietary supplement or cosmetic, not a medicine. None is intended to diagnose, treat, cure or prevent any disease. These statements have not been evaluated by the Food and Drug Administration (FDA).

Speak with a qualified healthcare professional before you start any supplement, especially if you take prescription medication, have a medical condition, or are pregnant or breastfeeding. Results differ between people.

Final Recommendation

This could suit a man who is trying to conceive and would like Tongkat Ali, selenium and zinc as a supplement next to a medical fertility evaluation. Two limits stand out. The finished product has never been tested, and the strongest study on its lead ingredient lacked a placebo group. Sperm need around three months to develop, which outlasts the 67-day refund window, so to keep the refund option, decide by about day 55 so returns arrive within 67 days of delivery. Prostate cancer or another hormone-sensitive condition is a reason to avoid it. Buy through the official site so the money-back guarantee stays available, and read its conditions before ordering.
