Scientifically Proven Effects of the Ingredients: 

Ascorbic acid (Vitamin C)

Vitamin C is the major antioxidant in seminal plasma of fertile men. Here its concentration is ten times higher than in blood plasma. Vitamin C protects spermatozoa against aggressive ROS (reactive oxygen species) and can improve sperm number and quality. However, the human body excretes vitamin C quickly. Therefore Fertilovit^® M  and Fertilovit^® M^plus both contain vitamin C that is released gradually in small quantities, thus providing a long term effect.

Zinc

Zinc is an important component of sperms: If the body lacks zinc, sperm production decreases considerably. In addition to this the motility of sperms diminishes as well. Studies have shown that taking a zinc supplement can improve sperm quality.

Vitamin E (D-alpha-tocopheryl acetate)

Vitamin E is localised in the cell membrane. Being an antioxidant it protects the membrane against oxidative stress. In various scientific studies men, who took a vitamin E supplement, had sperms that were significantly more resilient, motile and altogether healthier.   

Folic acid

Folic acid guards the sensitive DNA contained in the sperm head. Men with abundant folic acid have been found to have less sperms that cause a genetic disorder in case of conception. In addition to this, folic acid has been shown to lower homocysteine levels. This supports sperm development as well.

Selenium

Selenium is a highly effective antioxidant, which safeguards sperms’ DNA. Additionally, studies have revealed that selenium can enhance motility of sperms. 

Lycopene

Lycopene is a carotenoid featuring excellent antioxidant as well as anti-inflammatory properties. This has a positive effect on latent inflammations of the urogenital tract, reducing oxidative stress. Lycopene supplementation has been linked to an increase in sperm number and motility.

L-carnitine

In several studies L-carnitine ameliorated sperm motility substantially. 

Glutathione (red.) / N-acetyl-L-cysteine

Glutathione is the prevailing antioxidant in the human body. It safeguards cells from oxidative stress. According to multiple studies supplementation can lead to an increase in sperm motility and a decline of oxidative stress-related damages to the spermatozoa. 

However, glutathione’s absorption within the gastro-intestinal tract is limited. Its main precursor, N-acetyl-L-cysteine, on the other hand, is easily absorbed and has been shown to effectively boost glutathione-synthesis within the body. Therefore Fertilovit^® M and Fertilovit^® M^plus  contain N-acetyl-L-cysteine, raising intracellular glutathione levels considerably.

Coenzyme Q10

The body needs coenzyme Q10 (CoQ10) predominantly for energy production. However, it has powerful antioxidant properties, too, and can reduce the production of reactive oxygen species in seminal plasma markedly. Giving coenzyme Q10 to infertile men has been shown to result in a significant increase of pregnancy rates. 

Citrulline

Citrulline is the body’s main precursor for the production of the amino acid arginine. Supplementing citrulline has been shown to raise arginine levels substantially. This is required for healthy sperm development, because the body uses arginine for making the polyamines spermine and spermidine, which are present in seminal fluid in high concentrations. Spermine stabilizes sperm DNA, whereas spermidine plays an important role in cellular repair mechanisms. Spermidine levels have been found to decrease continually with increasing age. Arginine is also needed for the production of protamines, which are necessary for packaging of sperm DNA, thus stabilizing the DNA. Arginine’s precursor citrulline raises arginine levels effectively over an extended period of time.

A welcome side effect of raised arginine levels is that it also promotes male erection by releasing the mediator NO (nitric oxide).
