Description of the article « Fertility Factor 5 »
Quick Answer
Fertility Factor 5 is a male fertility supplement from Leading Edge Health, aimed at men and couples trying to conceive where sperm count, sperm shape (morphology) or sperm movement (motility) is the barrier. It is built around LJ100, a patented Tongkat Ali extract, at the same 200 mg daily dose used in the fertility study the maker cites — a dose match most fertility formulas never offer. There is no clinical trial of the finished formula itself, so the evidence is ingredient-level, but it is stronger ingredient-level evidence than this category usually has. Our score: 8.0/10.

Our Verdict
Fertility Factor 5 earns its score on one decision the maker got right: the hero ingredient is included at the exact dose used in its fertility research. LJ100 at 200 mg a day is not a token dusting of a famous extract — it is the studied amount, and the maker says so plainly. Around it sit four supporting ingredients with their own fertility literature, and a written 67-day money-back guarantee.
The limits are just as clear. No study has tested the finished five-ingredient formula, the maker publishes no full Supplement Facts panel with amounts for the other four ingredients, and the 67-day guarantee closes before the 3-month mark at which the maker itself tells you to judge results with a semen analysis. Buy it with the 3-month pack and the 3-month timeline in mind, and judge it the way the maker says to judge it — by a semen analysis, not by feel.
Sub-Scores
- Ingredients: 8.0/10 — Five named ingredients and no proprietary blend; LJ100 at the studied 200 mg dose, but no published amounts for the other four.
- Evidence: 8.5/10 — Several ingredient studies at or near the product dose, including a placebo-controlled LJ100 trial; no trial of the finished formula.
- Safety: 7.5/10 — The maker states the formula is all-natural with no known adverse side effects, but publishes no warnings or exclusions at all.
- Value: 7.5/10 — $69 a month, falling to $50 a bottle on the 6-month pack; the 67-day guarantee ends before the 3-month evidence timeline.
What Is Fertility Factor 5?
Fertility Factor 5 is a once-daily male fertility supplement made by Leading Edge Health under its VigRX brand family. The maker positions it for men — and couples — who are trying to conceive and where male-factor issues are the obstacle: low sperm count, poor sperm morphology and poor motility. The maker's stated aims are to improve sperm count, morphology and motility, support spermatogenesis (sperm production), increase semen volume, and support libido and sexual function.
The formula is built around one patented ingredient, LJ100, a Tongkat Ali (Eurycoma longifolia) root extract the maker describes as co-developed by researchers at MIT. That single-ingredient focus, plus a small supporting cast, is the product's identity: this is not a 30-ingredient multivitamin with a fertility label, it is a five-ingredient formula aimed at the parameters a semen analysis actually measures.
Key Ingredients
The maker names five ingredients. It does not publish a full Supplement Facts panel with per-ingredient amounts on its product pages. The only amount stated plainly is the LJ100 dose, given in the context of the study the maker cites.
- Tongkat Ali LJ100 — Patented Eurycoma longifolia extract. The maker states Fertility Factor 5 contains "the same amount of LJ100 as in this clinical trial": 200 mg per daily serving.
- Panax Ginseng — Included for sexual function and sperm parameters. Amount not published.
- Zinc — The maker describes its zinc as a "clinically proven dose" but does not publish the amount.
- Selenium — Amount not stated in a label panel. The maker's corporate page, discussing a study that used 50 mcg, remarks that this was "20 mcg less than the daily value in Fertility Factor 5," which implies 70 mcg per daily serving — but with no published label panel, that figure cannot be confirmed from the bottle.
- BioPerine — Patented black pepper extract, included to increase the bioavailability of nutrients, particularly selenium and zinc.
What We Like
- The hero ingredient is dosed at the studied amount. 200 mg of LJ100 a day is the dose used in the fertility study the maker builds its case on — the single most important honesty test a formula like this can pass.
- No proprietary blend. All five ingredients are named, and the formula is short enough to audit one by one.
- The evidence is specific, not vague. The maker cites named journals, participant counts and measured outcomes for its key ingredients rather than relying on "clinically studied" slogans.
- A real, written guarantee. 67 days, with the return terms spelled out on the maker's own pages.
- It tells you how to judge it. The maker recommends a semen analysis after at least 3 months — a measurable endpoint, which is rare in this category.
Good to Know
- There is no trial of Fertility Factor 5 itself. Every study behind it tested a single ingredient. The finished formula has never been clinically tested as a whole, and the maker does not claim otherwise.
- The guarantee closes before the evidence timeline. The maker recommends judging results after at least 3 months, but the refund window is 67 days. If you buy, your decision point is day 60 — not month three.
- The maker's own pages disagree on the LJ100 fertility trial. The brand site reports a semen analysis at 3 months and 11 spontaneous pregnancies across 6 months; the maker's corporate page says the study ran nine months and states different outcome figures (15% of partners impregnated). We take the brand page as primary, but the conflict is the maker's, and it is unresolved on their own sites.
- One cited study used more LJ100 than the product contains. A study the maker's retail page cites (109 men, published in eCAM) used 300 mg of LJ100 daily; the product provides 200 mg. The 200 mg fertility study matches the dose; the 300 mg study does not.
- The exact capsule count per day is not published. The maker says "once daily" and "daily" — it does not state how many capsules make up a serving on the pages we audited.
- No Supplement Facts amounts for four of five ingredients. Zinc, selenium, Panax ginseng and BioPerine amounts cannot be verified from the maker's published pages.
Who Should Not Use It
The maker publishes no exclusion list, no age limit and no medication cautions for Fertility Factor 5 on its product pages — there is simply no "who should not use this" information to report. The maker's own safety position, as stated, is that the ingredients are all-natural and that the product "has no known adverse side effects."
Our advice where a maker publishes no exclusions: treat that as a gap, not as reassurance. Male fertility problems can have medical causes that a supplement cannot address, and if you are undergoing fertility treatment, taking medication, or have a diagnosed condition, talk to your doctor or fertility specialist before using this or any fertility supplement.
Where to Buy
Fertility Factor 5 is sold through the maker's official store. The 1-month supply is $69 (MSRP $79); the 3-month supply is $169 ($56 per bottle) and the 6-month supply is $299 ($50 per bottle). Given the maker's own 3-month judging timeline, the 3-month pack is the sensible starting point. Every order is covered by the maker's 67-day money-back guarantee.

FAQ
How long does Fertility Factor 5 take to work?
The maker recommends starting with at least a 3-month supply and having a semen analysis after at least 3 months of use. The LJ100 fertility study the maker cites measured semen parameters at the 3-month mark. There is no honest shorter answer: sperm production is a months-long cycle, and the maker's own guidance reflects that.
Has Fertility Factor 5 itself been clinically tested?
No. The maker claims no trial of the finished formula. The evidence is ingredient-level — most importantly a study of 75 men given 200 mg of LJ100 daily (the same dose and ingredient in this product), plus a separate double-blind, placebo-controlled LJ100 study of 26 men on sexual function.
How much LJ100 is in Fertility Factor 5?
The maker states the product contains the same amount of LJ100 as in its fertility trial: 200 mg per daily serving.
How many capsules do I take each day?
The maker describes Fertility Factor 5 as a once-daily supplement but does not state the exact number of capsules per day on its product pages. Check the bottle directions when it arrives — and note the gap before you buy if precise dosing matters to you.
What if it doesn't work for me?
The maker offers a 67-day money-back guarantee: try it for up to 60 days and return the containers within 67 days of receiving your order for a refund of the product purchase price, excluding shipping and handling. Note that this window closes before the 3-month timeline the maker recommends for judging results.
Does Fertility Factor 5 contain testosterone or hormones?
No hormone ingredient is listed. The formula is LJ100 (Tongkat Ali extract), Panax ginseng, zinc, selenium and BioPerine. The maker markets it around sperm count, morphology and motility — not hormone replacement.
Also Consider
- Semenax — The volume-focused formula from the same maker; a better fit if semen volume, rather than fertility parameters, is your main concern.
- Volume Pills — Another volume-led option in the same category, worth comparing on price and guarantee.
