תַקצִיר

Korean Red ginseng (KRG) has long been applied to various diseases as a health-promoting herbal medicine in Korea. Many clinical studies of ginseng have been performed to elucidate its therapeutic characteristics. KRG has been shown to be effective in many diseases, such as cancers, hypertension, Alzheimer's disease, diabetes, acquired immune deficiency syndrome, and sexual dysfunction. Several studies have indicated effects of ginseng on improving spermatogenesis in animals. The major mechanisms behind these effects were speculated to be anti-oxidant and anti-aging effects, as well as modulation of the hypothalamus-pituitary-testis axis [7 - 10]. However, there have been no controlled human clinical trials to evaluate the effects of KRG on spermatogenesis in patients with male infertility.
Only a small proportion of causes of male infertility are currently curable, including male hypogonadal disorders that can be cured by gonadotropic agents, and obstructive azoospermia that can be corrected by surgery. In addition, evidence-based medicine has revealed that most empirical treatments are ineffective. Similarly, the efficacies of carnitine, anti-estrogens, kallikrein, vitamins C and E, and glutathione have not been confirmed.
Therefore, the investigators investigated the effects of KRG on semen parameters in male infertility patients. This is the first placebo-controlled trial to evaluate the therapeutic effects of KRG in male patients.
