Infertility (Male & Female) Protocol
Coenzyme Q10 and L-Carnitine are the core of this stack, with 2 supporting supplements. Each row gives the amount the protocol lists and the grade our evidence database holds for that supplement in Infertility (Male & Female).
We are re-verifying the studies cited on protocol pages; only confirmed citations are shown.

How this protocol works
In plain language
Infertility affects about 15% of couples and can have male, female, or combined factors. For men, sperm quality (count, motility, morphology) is key. For women, egg quality and ovarian function matter most. Both sperm and eggs are highly dependent on mitochondrial energy production, which declines with age and oxidative stress.
- Coenzyme Q10 is crucial for both male and female fertility. In men, it improves sperm motility by enhancing mitochondrial energy production. In women, particularly those over 35 or undergoing IVF, CoQ10 can improve egg quality and ovarian response. The ovaries have among the highest CoQ10 requirements of any tissue.
- L-Carnitine transports fatty acids into mitochondria for energy production—sperm cells are highly dependent on this process for motility. Meta-analyses consistently show improved sperm concentration, motility, and pregnancy rates. Acetyl-L-carnitine may provide additional antioxidant benefits.
- Folate is essential for DNA synthesis and cell division, making it critical for sperm production and early embryonic development. Both partners should supplement, not just women. Low folate in men is associated with poor sperm quality and chromosomal abnormalities.
- Zinc is concentrated in the prostate and is essential for testosterone production and sperm development. Deficiency is common in infertile men. Zinc also protects sperm DNA from oxidative damage.
Expected timeline: Sperm production takes about 74 days, so improvements in male parameters take 2-3 months. Women should supplement for at least 3 months before conception attempts or IVF cycles.
