Testosterone, an essential precursor of estrogen in women, is made in the ovaries and adrenal glands. There is a steady decline in testosterone levels from the 20s through menopause. With surgical menopause, the level of testosterone drops precipitously. No clear lower limit of testosterone has been established; however 15 ng per dL ( nmol per L) commonly is used. One study 38 found that women with 0 to 10 ng per dL (0 to nmol per L) had markedly decreased sexual desire in all situations and absent or markedly decreased orgasms. Because of studies like this, supplemented with anecdotal evidence, many women have been started on testosterone therapy.

Some Ginseng supplement manufacturers are sloppy and thus Ginseng has a reputation for having contaminants, including lead and various pesticides. Thus, buying only the best brands is definitely wise. For example, Consumer Labs failed 45% of tested products in a recent review for either having insufficient ginsenosides or being contaminated. However, a number of brands passed Consumer Labs' analysis with flying colors. Probably the best was Solgar - Korean Ginseng Root Extract, 60 veggie caps which was not only contaminant-free but also had abundant ginsenoside content.
