Fertility Factor 5 Review 2026 — Five Ingredients Analyzed

Introduction: What This Review Covers

Fertility Factor 5 is a male fertility supplement from Leading Edge Health. Our old page listed the wrong ingredients (zinc citrate, selenium, ashwagandha, folic acid and CoQ10); the current official formula is LJ100 Tongkat Ali extract, Panax ginseng, zinc, selenium and BioPerine. This review covers the current formula, what the ingredient research shows and who it may suit.

We check the current formula and disclosed doses, whether the product itself has been tested in a published trial, what the ingredient research shows, the guarantee terms and the main safety cautions. We also summarize three other men's products we've reviewed. None of them is designed for fertility: Testosil is a testosterone support formula, Semenax targets semen volume and VigRX Nitric Oxide is an erection product. We earn affiliate commissions on purchases made through our links, which is disclosed above.

Our Verdict on Fertility Factor 5

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

How to Evaluate Products in This Category

Before looking at the details, these are the checks that matter most:

• Dose alignment with published research: An ingredient at a fraction of the studied dose is unlikely to match the research. Check whether the label discloses each dose and compare it with the amounts used in human studies.
• Published human evidence: Look for a published, placebo-controlled trial of the product itself. Most products in this category have none and rely on ingredient studies, animal data or traditional use.
• Branded ingredients: Branded extracts are standardized, and some have their own studies, often funded by the supplier. A brand name alone doesn't mean the product uses a studied dose.
• Manufacturing and testing: Supplements sold in the US must be made under the FDA's current good manufacturing practice (cGMP) rules. An independent certificate of analysis is a useful extra check on purity and dose.
• Refund terms: Read the conditions, not just the number of days. Many guarantees require containers to reach the warehouse within the window and don't refund shipping.

Fertility Factor 5 — Detailed Analysis

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

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

What We Found

• Formula: Five ingredients per the official formula page: 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 stated in text. It does not contain ashwagandha, folic acid or CoQ10.
• Evidence: No trial of Fertility Factor 5. The main LJ100 study (75 men with unexplained infertility, 200 mg a day) reported better semen measures but had no placebo group. Selenium has small placebo-controlled trials showing better sperm motility in subfertile men; evidence for zinc and ginseng is mixed.
• Guarantee: 67 days from delivery: return empty containers (unopened plus the first two opened are refundable) so they arrive within 67 days, "no exceptions"; shipping isn't refunded; one refund per customer.
• Cautions: Tongkat Ali may affect hormone levels, so avoid it with prostate cancer or other hormone-sensitive conditions. Ginseng can interact with warfarin and diabetes medicines. It's no substitute for a semen analysis and fertility workup.
• Pros: Short, focused formula with key doses (LJ100, selenium) stated; LJ100 dose matches the amount used in its main study; Selenium has some placebo-controlled evidence for sperm motility; Established seller with a written 67-day guarantee.
• Cons: No trial of the finished product, despite strong marketing claims; Main LJ100 fertility study had no placebo group; Ginseng and zinc amounts not stated in text; Three months of use is needed to see sperm changes, longer than the 67-day refund window.

Semenax — Detailed Analysis

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

A 16-ingredient amino acid and herbal blend from Leading Edge Health marketed for semen volume. One small, company-funded trial found a modest volume increase versus placebo.

Semenax may suit healthy men who want to try a modest boost in ejaculate volume and are willing to buy direct and track the 67-day return window. Its single trial is small, company-funded and showed no clear benefit for men with low volume, sperm quality, erections or orgasm.

What We Found

• Formula: 16 amino acids, herbs and nutrients with no amounts on the official ingredients page, including Swedish flower pollen, L-arginine, L-lysine, zinc, L-carnitine, maca, pumpkin seed and Butea superba.
• Evidence: One small, company-funded 2-month placebo-controlled trial (63 men analyzed; published 2022) found a modest rise in ejaculate volume versus placebo, but no clear benefit in men with low volume and no difference in sperm count, motility or sexual function.
• Guarantee: Try for 60 days; empty containers must reach the warehouse within 67 days of delivery, "no exceptions"; shipping isn't refunded; one refund per customer.
• Cautions: L-arginine can interact with nitrates, ED drugs and blood pressure medicines. Counterfeits have been documented, so buy direct.

Testosil — Detailed Analysis

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

A 4-capsule testosterone support formula from Leading Edge Health built on D-aspartic acid and KSM-66 ashwagandha (300 mg per serving) plus zinc, vitamin D and botanicals. Doses are disclosed; the product itself has no clinical trial.

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

What We Found

• Formula: Per 4-capsule serving (from a 2023 batch certificate linked from the official site): 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 others. All doses are disclosed.
• Evidence: No trial of Testosil itself. KSM-66 at 600 mg a day (two servings) raised testosterone more than placebo in one small 8-week trial of young men doing resistance training (Wankhede et al., 2015), while 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: Advertised as a "lifetime" guarantee: the refund covers unopened bottles plus one opened bottle, shipping isn't refunded and it's one order per customer. Some wording on the guarantee page is inconsistent, so confirm with customer service first.
• Cautions: One 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 — Detailed Analysis

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

A VigRX-brand capsule combining L-citrulline and L-arginine, amino acids the body uses to make nitric oxide; doses are not disclosed and the product has not been clinically tested.

VigRX Nitric Oxide Support may suit healthy men who want an L-arginine and L-citrulline product, two amino acids with some evidence for mild erection problems at gram doses. Its doses aren't disclosed and the product itself hasn't been studied, and anyone on nitrates, ED drugs or blood pressure medicines should check with a doctor first.

What We Found

• Formula: L-citrulline and L-arginine (per a third-party review); doses and serving size aren't disclosed.
• Evidence: No trial of the product. L-arginine and L-citrulline have some evidence for mild erection problems at gram-level doses; without disclosed doses, we can't tell whether this product reaches them. It isn't a fertility product.
• Guarantee: 67-day money-back guarantee per a third-party review; exact conditions not verified.
• Cautions: L-arginine can lower blood pressure further with nitrates, ED drugs or blood pressure medicines.

Safety Considerations

All products discussed in this article are sold as dietary supplements or cosmetics, not medicines. They are not intended to diagnose, treat, cure or prevent any disease. These statements have not been evaluated by the Food and Drug Administration (FDA).

Always consult a qualified healthcare professional before starting any supplement, particularly if you take prescription medication, have an existing medical condition, or are pregnant or breastfeeding. Individual results vary.

Final Recommendation

Fertility Factor 5 may suit men trying to conceive who want a Tongkat Ali, selenium and zinc supplement alongside a medical fertility evaluation. The product hasn't been tested, and its main ingredient's best study had no placebo group. Sperm take about three months to develop, longer than the 67-day refund window. To keep the refund option, decide by about day 55 so returns arrive within 67 days of delivery. Avoid it if you have prostate cancer or another hormone-sensitive condition. If you buy, use the official site so you can use the money-back guarantee, and read its conditions first.
