Nettle Extract's Effects A highly concentrated extract from the nettle root provides a unique mechanism for increasing levels of free testosterone. Recent European research has identified constituents of nettle root that bind to SHBG in place of testosterone, thus reducing SHBG's binding of free testosterone. The prostate gland also benefits from nettle root. Nettle root inhibits the binding of DHT to attachment sites on the prostate membrane. While free testosterone stimulates sex cell receptor sites in the brain, there are aging-induced changes in the genital regions of men and women that must also be corrected if a youthful libido is to be maintained or restored.
Few doctors understand the biochemical mechanisms involved in sex organ stimulation.
It is well known that free testosterone is required to activate sex cell receptor sites in the brain. For stimulation of sex cells in the genital area, however, a naturally produced chemical is needed to relax blood vessels in a part of the human anatomy called the corpus cavernosum. For men, penile erection and optimal sensation mandates proper function of the corpus cavernosum, and for women, the ability to enjoy sex and achieve orgasm is often dependent on clitoral corpus cavernosum activity. The corpus cavernosum becomes active when it becomes engorged with blood during periods of sexual excitement, and its stimulation is dependent on the relaxation of genital muscles during sexual arousal. Nitric oxide and its metabolite cyclic GMP are the two dominant biochemicals that induce genital muscle relaxation, and subsequently increased blood flow to the sexually sensitive corpus cavernosum.
