Semevol is marketed as a men’s sexual health supplement aimed at boosting semen volume, improving orgasm intensity, and enhancing sexual performance. It features a mix of vitamins, amino acids, herbal extracts, and absorption enhancers. Most of the formula’s components are more strongly associated with general sexual wellness, libido, erectile function, and prostate health, than with direct increases in ejaculate quantity.
The Science Behind Semen Volume
Semen volume depends on several factors: hydration status, frequency of ejaculation, prostate and seminal vesicle function, testosterone levels, and overall reproductive health. The seminal vesicles contribute roughly 65–75% of semen fluid, the prostate about 25–30%, and the testes a small fraction containing the sperm cells themselves. True volume increases generally require changes in glandular fluid production, not just improvements in blood flow or antioxidant status. This is why many “volume booster” supplements underperform in clinical settings — they target the wrong mechanisms or underdose the right ones.
Ingredient Analysis: What’s in Semevol
Vitamin E (450 IU): A powerful antioxidant that can protect sperm from oxidative damage. It may improve motility and viability, but its effect on semen volume is minimal.
Zinc Picolinate (28 mg): Essential for sperm production and hormonal balance. Can improve semen parameters in deficient men, but surplus zinc offers no clear additional volume boost.
Selenium (220 mcg): Supports sperm motility and testicular health. Benefits fertility, but volume increases are not well-supported by human trials.
Sunflower Lecithin (1,650 mg): In animal studies, lecithin supplementation increased semen fluidity and sometimes volume, but human data are lacking.
L-Citrulline (2,500 mg): Improves blood flow via nitric oxide production, aiding erectile function. No direct evidence for increasing semen volume in humans.
L-Carnitine (750 mg): Supports energy metabolism in sperm and may improve motility, but not fluid output.
Pygeum (200 mg): Used for prostate health, which could indirectly support seminal fluid production, but volume-specific data are minimal.
BioPerine: Enhances absorption of other nutrients; no direct impact on sexual health. The amount of this Black Pepper Extract is not listed on the supplement facts. It is not safe to take unknown amounts of supplements.
Where the Formula Falls Short
Semevol’s main weakness is that its formula focuses heavily on general sexual function rather than directly stimulating the glands responsible for producing seminal fluid. Several of its ingredients — like L-carnitine — are more relevant to erectile performance than volume. Others, like Vitamin E and selenium, have benefits for sperm health but no strong link to ejaculate quantity. The result is a product that may improve certain aspects of sexual wellness but is unlikely to deliver substantial or consistent increases in semen volume.
Why Load Boost by VB Health Is Different
Load Boost is formulated with ingredients that specifically target the physiological pathways of semen production. It includes zinc, lecithin, L-citrulline, pygeum, bromelain, and copper in clinically relevant doses to support glandular fluid output, prostate health, and blood flow simultaneously. This multifaceted approach is backed by both human and animal data, making it credible as a semen-volume enhancer versus a general-purpose sexual health supplement. For men seeking measurable results in semen volume and orgasm intensity, Load Boost offers a science-aligned alternative.
