In the area of its origin to ginseng (whether Asian or American ) to enhance sexual function quite standard prescribes. ( Murphy2002gsb ) While the potency effect of ginseng is usually easily noticeable, it is more a question of the extent to which ginseng helps its more traditional indication - to improve fertility.
The short answer to this question would have been: relatively little. Compared for example to cardiovascular effects, the traditional indication ginseng to increase fertility donated yet only about ten publications. Jenda the first clinical study was an Italian Salvati1996epg whereby in 30 male patients with low sperm counts and another group of 16 patients with idiopathic varicocele ginseng significantly enhanced both the number and activity of motile sperm. Chemoprotektivnímu effect of ginseng on fertility aspect was devoted to the study Hwang2004pgi , according to which water extract of P. ginseng male guinea protect against damage fertility after exposure to dioxins poloychlorovanému. The experiment with the same dioxins and similar results was repeated in rats ( Park2006tet ). Later, it was with positive results investigated the protective effect of the extract of red ginseng before reproductive toxicity ethanol ( Jang2011erg ). Radioprotective effect against γ radiation to the tissue of the testes was reported in mice ( Kumar2003rep ). Further experimental studies ( Sawiress2011ege ) says that ginseng improved fertility in diabetic rats. The downside of this latest study is in my opinion the low number of animals (10 treated, 10 positive control, negative control 10, up 30 rats), which does not a priori highly significant conclusions. Perhaps most compelling is the latest Italian clinical study Cai2012sqp , which was observed 206 patients with genital chlamydia (Chlamydia trachomatis), concluding that the use of ginseng with antibiotics against chlamydiosis led to a relative improvement in semen quality.
Panaxosidů effect on sperm capacitation
Sperm capacitation is the process by which sperm after ejaculation develop the ability to fertilize an egg. Now effect on capacitation was investigated for typical content substances of ginseng - panaxosidů. It is not clear whether this effect is associated with the previously mentioned improvements in fertility, or are independent effect. Researchers to reflect on capacitation perhaps brought recently clarified the role of ginseng in a cascade of NO , which is also responsible for erection . Specifically, the ginsenoside Re was observed in vitro that this improves mobility ( Zhang2006gif ) and capacitation ( Zhang2006gif ) with human sperm. Ginseng also contributes to increasing libido and fertility by increasing the volume of ejaculate, which is important for successful fertilization. Cascade NO plays a role not only in male erection, but also in the female vzušení and orgasm, which is again very important for fertilization.
