The Claim: If you squint and have an excellent imagination, mature ginseng roots vaguely resemble a human body. That ties into folk ideas for finding medicines–in this case, the idea that a plant that looks like a person must contain materials that help sick people. Ginseng was traditionally used as a tonic to treat erectile dysfunction and low sexual drive in men (as well as many other complaints).

Classically the neuro-physiology of ejaculation traces the 3 Phases in which ejaculation is a complex event involving the (I) the propulsion of sperm and seminal plasma into the prostatic urethra which is accompanied by (II) bladder neck closure and (III) coordinated contractions of the bulbocavernosus and ischiocavernosus muscles, striated muscles of the pelvic floor, lower limbs and trunk. In the Asian Society of the Aging Male Study  63% have reduced erection, 68% reduced or absent ejaculation and 19% pain or discomfort at ejaculation. Disorders of ejaculation can be due to: (I) disorders of production of sperm or seminal plasma/prostatic secretions (II) disorders of propulsion. In the case of anejaculation (absence of ejaculatory) which is the ultimate disorder of ejaculation, the causes can be best classified as (I) primary or secondary. After covering psychogenic causes of ejaculation failure, the organic causes due to non-dynamic and obstructive etiologies in the prepubertal and post pubertal male will be highlighted. More details will be given on retarded ejaculation, premature ejaculation, aspermia, painful and weak (poor propulsive force) ejaculation. The evaluation of the patient must include a detailed history taken from the patient and often his partner. Aside from haematologic tests, various forms of radiological and ultrasonic imaging, neurophysiologic studies may be required. For the general practitioner the commonest scenario will be in the ED Clinic with abundant men with performance anxiety presenting with premature ejaculation. In the male aging clinic lack of arousal is the commonest cause of retarded orgasm and ejaculation but this group is plagued by decreased touch sensitivity, the need for more direct stimulation, reduced drive to orgasm, a less intense orgasm, ejaculation being weaker and of reduced quantity and disturbing complaints of a longer recovery period and less number of attainable orgasms per day or week. Thus it is not mere rumor that “by the time a man reaches 55, the refractory period to ‘do it again for a man’ increases to 12 hours or even up to a week”. In the STD clinic, painful or bloody ejaculation is frequently seen. The Condom may cause condom retarded orgasm/ejaculation.
No matter what erectile dysfunction treatment or treatments (whether herbal remedies or not) a man ultimately decides upon, experts say it's important to eat healthily and to avoid smoking and heavy drinking. Moreover, adequate exercise, stress reduction, and sleep can improve erectile dysfunction in many. In addition, says Lamm, "A loving, receptive, and responsive partner is a home run. After all, this is still a couple's issue."
DHEA. Testosterone is essential for a healthy libido and normal sexual function, and erectile dysfunction sufferers known to have low testosterone improve when placed on prescription testosterone replacement therapy. Similarly, studies have shown that taking over-the-counter supplements containing DHEA, a hormone that the body converts to testosterone and estrogen, can help alleviate some cases of ED. But DHEA can cause problems, including suppression of pituitary function, acne, hair loss and its long-term safety is unknown, says McCullough. For this reason, many experts discourage use of the supplements.
Ginkgo biloba. Ginkgo is an herb that is used in Chinese medicine that’s thought to improve blood flow. "Any ED treatment that improves blood flow may help," explains Dr. Harris. "An erection is just blood in and blood out." However, the evidence that ginkgo can improve blood flow in ED is limited, and most experts say the jury is still out. In addition, ginkgo can increase the risk for bleeding problems if combined with certain medications, such as warfarin (Coumadin).
Ginkgo biloba. Known primarily as a treatment for cognitive decline, ginkgo has also been used to treat erectile dysfunction -- especially cases caused by the use of certain antidepressant medications. But the evidence isn't very convincing. One 1998 study published in the Journal of Sex & Marital Therapy found that it did work. But a more rigorous study, published in Human Pharmacology in 2002, failed to replicate this finding. "Ginkgo has come out of fashion in the past few years," says Ronald Tamler, MD, assistant professor of medicine and codirector of the men's health program at Mount Sinai Medical Center in New York City. "That's because it doesn't do much. I can say that in my practice, I have not seen ginkgo work -- ever."
A number of nonprescription products claim to be herbal forms of Viagra. Some of these products contain unknown amounts of ingredients similar to those in prescription medications, which can cause dangerous side effects. Some actually contain the real drug, which should be given by prescription only. Although the Food and Drug Administration has banned many of these products, some potentially dangerous erectile dysfunction remedies remain on the market.
