1. What is Stymen and what is it used for

Stymen contains the active substance prasterone (dehydroepiandrosterone, DHEA), which belongs to the group of steroid hormones. Its amount in the body decreases with age. The highest concentration of DHEA occurs in men between 20 and 30 years of age, and after 30 years, it decreases gradually. Administration of DHEA may have a beneficial effect on, among other things, erection, libido, well-being, immune system, and musculoskeletal system.
Supporting effects of DHEA have been demonstrated in the following cases:

  • andropause in men;
  • reduced physical and mental fitness, especially in older people;
  • mood disorders, depressive states, sleep disorders, decreased drive;
  • erectile dysfunction and decreased sexual activity;
  • obesity;
  • decreased tissue sensitivity to insulin;
  • circulatory disorders;
  • decreased immune resistance;
  • primary and secondary adrenal insufficiency.
