Effex Tribulus is a herbal drug based on tribulus terrestris stem and leaves extract containing steroid saponins. The drug has a tonic effect and it stimulates the reproductive system functions, improving sexual libido and prolonging erection in men. Effex Tribulus stimulates spermatogenesis, increasing the number of spermatozoa and their mobility.

Tribulus terrestris has been used in traditional medicine in China, India, Sudan, Pakistan and other countries for centuries. In India the plant is used in the form of decoction to treat urinary tract infections, urolithiasis, dysmenorrhea and edema. A scientific research based on World Health organization criteria (published in Cryobiology magazine, 2017-April) showed that the protective effects of tribulus terrestris, which improves human sperm motility and viability, may be due to its antioxidant properties. On the basis of the results, the researchers concluded that the plant can be used as a safe therapeutic alternative to current modalities for the management of motility dysfunction in males.

The studies show that the plant’s compound protodioscin is metabolized in the body to dehydroepiandrosterone (DHEA), which has a beneficial effect on the immune system, cell membrane integrity, erectile function and cholesterol metabolism. Cholesterol is known to be essential for the synthesis of all steroids, including DHEA, testosterone and estradiol, which explains the hypolipidemic effect of the drug. Other saponin components of the plant enhance the effect of protodioscin. The research showed the effect of a hydroalcoholic extract of tribulus terrestris on serum glucose and lipid profile of women with diabetes mellitus.


To be used as a part of complex therapy of:


  • erectile dysfunction accompanied by decreased libido;
  • male infertility due to reduction in the quantity and quality of spermatozoa in the secreted semen, varicocele surgery or immunological infertility;
  • dyslipidemia in order to lower cholesterol.
