There are five major areas involved in female and male sexual enhancement:

1. Psychological/mental -- The causes of psychological sexual dysfunction and low libido are numerous, and it is difficult to list them all, but most often low libido is related to depression, performance anxiety, marital stress or relationship problems, life crisis, financial difficulties, religious repression, or some type of mental illness. Sexual enhancement is possible through various forms of therapy, stress release, vacation, etc.

2. Hormonal -- Androgens, such as testosterone, are a major component of libido. Testosterone levels decline about 1 percent each year in men, which may contribute to lower male libido with aging. Testosterone also declines with age in women leading to a decrease in female libido. Women who have had surgical removal of the ovaries notice a drop in sexual interest. Sexual enhancement through replacement of androgens can be helpful in those with age related sexual dysfunction. Testosterone is available by prescription only. An over the counter hormones, such as DHEA, converts into testosterone and thus has a positive influence on libido. Pregnenolone is another over the counter hormone that may increase testosterone levels and thus lead to sexual enhancement. However, hormones may not be safe to use for sexual enhancement, therefore aphrodisiac herbs are a great alternative.

3. Vascular -- Alterations in the flow of blood to and from the penis are thought to be a common cause of male erectile dysfunction. For instance, medical conditions such as atherosclerosis (hardening of the arteries), high cholesterol, hypertension, or diabetes reduce blood flow to the penis and genital organs thus leading to difficulty with erection or genital swelling. Proper diet and exercise can reduce the risk. Additional factors that can impede blood flow include penile injury, surgery in the pelvic or abdominal area, and sitting on a bicycle too long. Men who log several thousand miles a year on their mountain bikes suffer scrotal damage that could reduce their fertility.  Some of these health problems, if treated appropriately, can lead to sexual enhancement.

4. Neural -- Nerve damage from disorders such as diabetes, multiple sclerosis, Parkinson’s disease, and stroke affect the brain’s ability to respond to sexual stimulation. In women, abdominal or pelvic operations can occasionally lead to nerve damage. Sexual dysfunction is common in men undergoing surgical treatment for prostate enlargement or cancer.  

5. Chemical -- Some chemicals involved in the human sexual response and libido include dopamine, acetylcholine, and nitric oxide. Sexual enhancement is quite likely through manipulation of these brain chemicals by using natural herbs and supplements.

Sexual enhancement and Medical conditions
Certain medical conditions reduce libido, performance, or enjoyment. These include hypertension, diabetes, high cholesterol, cardiovascular disease, peripheral vascular disease, and neurologic disorders, and insomnia.

Drugs that interfere with Sexual enhancement
Drugs that interfere with libido or sexual function include some anti-hypertensives, SSRIs, sedatives, sleeping pills, and beta-blockers. Alcohol's negative affect on libido increases with age. Smoking can reduce genital blood flow.

Sexual Enhancement drug 
There are several sexual enhancement drugs including Viagra, Cialis, and Levitra. These drugs work very well in dilating blood vessels leading to a strong erection, however they do little else for sexual enhancement, such as libido, sensation, and sexual stamina. Plus, they have side effects. It has been reported that Viagra in rare cases can cause permanent blindness. Sexual enhancement supplements are, as a rule, much safer. Which is the best sexual enhancement drug? This is difficult to say since each person has their own preference. 

Female and Male Sexual Enhancement Research Update
Exercise and weight loss may lead to sexual enhancement in obese men, researchers in Italy report. In a new study of more than 100 obese men with erectile dysfunction, nearly a third regained normal sexual function after participating in an intensive weight loss program. 

Female and Male Sexual Enhancement emails 
Q.  Have received Spam mail and seen on web sites sexual enhancement pills or sexual enhancement products that the vendors say are guaranteed to increase the size of your penis.  The ingredients seem to be the common supplements spoken about with regard to penile health.   Is there any substance to these claims and these pills lead to sexual enhancement?
     A. I have gotten similar emails. I am not aware of any sexual enhancement pills that permanently increase the size of a penis, but I am 100 percent certain that many herbal combinations do have sexual enhancement properties. 

Q. Does arginine lead to sexual enhancement?
     A. In my experience, I have not found arginine to be an effective sexual enhancement supplement, at least in the short term and in dosages smaller than 5 grams. Long term use may have an effect.

Q. Does exercise lead to sexual enhancement?
     A. Perhaps not directly, but indirectly exercise can help you sleep deeper which does wonders for sexual enhancement. Exercise also makes you feel better about your body, and this could also have an influence on your libido.

Q. My doctor told me that I need testosterone sexual enhancement ever since I've had my ovaries removed. Do you think herbs can restore libido without resorting to hormones? I really don't want to take testosterone.
     A. Most doctors don't realize that there certain natural herbs have sexual enhancement abilities as much as hormones. The best sexual enhancement products depend on the user. There are literally hundreds or thousands of female and male sexual enhancement pills that are marketed, and if you try a few it is quite likely you will find one that works for you.

Q. Is male enhancement possible as I've read many magazine ads that claim herbal pills lead to natural male enhancement? I want to take a male penis enhancement pill to grow at least one more inch.
     A. It depends what you mean by male enhancement. If you mean a larger penis growth, that is a false advertising claim, however, if male enhancement means better and longer lasting erections, more stamina, better sensation and more powerful orgasms, then there is no doubt that many herbs lead to natural male enhancement.

Q. What do you think of Enzyte, the male sex enhancement pill, or Vig Rx, the male enhancement product?
     We don't comment on products from other companies. We just focus on our own natural male enhancement pill called Passion Rx. We are proud of it and think it works great and most users prefer it over a male enhancement drug. . 

Q. Is mucuna pruriens an effective male sexual enhancement supplement?
     A. Some people find the increased dopamine from mucuna to have an herbal male enhancement effect. So, we do think mucuna to be a good herbal male libido enhancement supplement.

Q. What's the best male sexual enhancement product or vtiamin?
     A. This is impossible to say since each person is unique, and some people may respond to one male sexual enhancement pill while others may respond to a completely different male enhancement product. Many of the herbs in Passion Rx are quite effective. You can find a list of male enhancement herbs near the top of the page.

Q. Does the mineral zinc lead to male sex enhancement?

     A. I would say fish would be my pick on the best food for both male and female sexual enhancement.

Q. What's your favorite male sexual enhancement pill or female sexual enhancement product?
     A. I have a number of herbs that I like including ashwagandha, tongkat ali, horny goat weed and mucuna pruriens. They each have their advantages and disadvantages. My favorite male and female sexual enhancement product is actually a blend I created called Passion Rx.
Q. What's your opinion on sexual enhancement cream?
     A. I have not studied sexual enhancement creams so I don't have an opinion whether they work or not.
