MACA(Lepidium meyenii Walp) The actions of four alkaloids from maca root may also serve to increase animal fertility. One of the researchers heading
current studies on maca, Peruvian biologist Gloria Chacon de POPOVICI, Ph.D., suggests that maca alkaloids act on the hypothalamus-pituitary axis and the adrenals. These areas of the body produce hormones as well as energizing substances like adrenaline. The end result could be an increase in energy, vitality, and virility. Still, no studies of maca itself have been conducted on human sexual response, despite physicians' claims that maca positively affects ovarian function in women, and, as mentioned previously, erectile function in men.link
Horny Goat Weed (Epimedium Sagittatum) - Epimedium sagittatum
appears to be a chinese herbal treatment for the "promotion of yang energy". Some people use it to enhance stamina and/or promote sexual energy. There are currently a lot of herbal products sold which contain Epimedium sagittatum. Animal studies have shown that epimedium may function a bit like an adaptogen (such as cordyceps, rhodiola, ashwagandha, and ginseng) by increasing levels of epinephrine, norepinephrine, serotonin, and dopamine when they are low (an energy-promoting effect), but reducing cortisol levels when they are elevated (an anti-stress effect). There is also evidence that epimedium can restore low levels of both testosterone and thyroid hormone (bringing low levels back to their normal levels) - which may account for some of the benefits of epimedium in improving libido (sex drive).Link
Ashwagandha - Withania Somnifera Recommended in the
ancient Kama Sutra for heightening sexual experience, Ashwagandha is easily the most potent aphrodisiac in the entire botanical kingdom. It has the ability to restore sexual drive, increase endurance and improve overall vitality while promoting a calm state of mind. Ashwaganda is an "adaptogenic" herb which nourishes nerves and improves nerve function to help your body adapt to stress, one of the common cause of sexual problems.
Catuaba Bark The historic traditional use of this herbal tonic is legendary.
Many say it is the most famous of all the Brazilian aphrodisiac plants. It is a strong tonic and nervous system fortifier. It is known for its general capability of giving strength and relieving fatigue. The effect is pronounced in men, especially as a libido enlivener.
Avena Sativa is an herbal extract from wild oats straw. It is sometimes known as green oats,
and is now commonly taken as a natural aphrodisiac. Originally, however, it had been used in India for many centuries to treat opium addictions. Avena Sativa is believed to free up testosterone in both men and women. One of the main effects of testosterone is a healthy libido. Avena Sativa does not create more testosterone in the body, but is thought to free some that is in a “bound” state. Approximately 2% of the body’s testosterone is in a “free” state; the other 98% is bound to protein molecules. The free state testosterone is considered the active form; when it is low, not only does our libido diminish, but our bodies store fat more readily, and lean muscle decreases. link
Tribulus terrestris is a plant that grows in many tropical and moderate areas of the world. Many different cultures have used it for a number of conditions.
For example, the Greeks used Tribulus terrestris as a diuretic and a mood-enhancer. Studies show that it works very well when stacked with DHEA and androstenedione. It increased testosterone levels in a different way, however, than either DHEA or andro do. Instead of being a testosterone precursor, it leads to the production of the luteinizing hormone (LH). When LH levels are increased, the natural production of testosterone also increases. LH is a hormone that also deals with sex drive. Now one can understand why it has been used to increase fertility and help with impotence. Laboratory animal studies found that Tribulus terrestris increased sperm count as well as motility levels after taking it for 30 days.

Other fators which influence semen production:
L-CARNITINE This amino acid is found in high concentrations in healthy sperm. Proven to significantly increase the percentage of highly motile sperm
ARGININE HCL - L-arginine, a testosterone precursor, in adequate dietary amounts is necessary if a man is to maintain a normal sperm count. Adequate L-arginine is also important for sperm mobility, both because it is the precursor in the synthesis of polyamines and because it is the precursor to nitric oxide.
The polyamines putrescine and spermidine are organic components important to sperm movement. Nitric oxide within spermatozoa also appears to be necessary for adequate sperm mobility. In fact, pathospermia (abnormal sperm) sometimes seems to be caused by abnormal arginine metabolism.Arginine aspartate, 9 g daily, has been effective in some cases of asthenospermia (reduced sperm mobility).
Also, L-arginine, 4 g daily, has been shown to improve sperm counts in men with oligospermia, especially those with counts between 20 million and 50 million sperm per ejaculate.
L-LYSINE - Researchers find that this amino acids plus zinc increases sperm produced, stimulates testosterone production, and improves semen quality.
ZINC OXIDE Zinc is among the most important nutrient minerals in regards to male fertility. Zinc levels in the seminal plasma (the fluid in which the sperm exist) are directly related to sperm mobility, and dietary zinc restriction reduces both sperm count and seminal plasma volume. Moreover, infertile men with azoospermia (absence of living sperm). as well as those with oligospermia (low sperm count), may have decreased seminal zinc levels.
Several clinical trials have found zinc supplementation to be an effective fertility treatment. In one study,infertile men with unexplained low sperm counts (below 40 million/mL) received 220 mg of zinc sulfate daily. After four months, there were significant improvements in sperm count and in the number of progressively motile and normal spermatozoa--and the wives of two men conceived.
The results of other studies suggest treatment of a low initial plasma testosterone14 or surgical correction of a varicocele (abnormal dilation of spermatic cord veins) prior to zinc supplementation15 increase the chances of success. In this latter study, of the entire group of infertile men who received zinc, only those who had a varicocelectomy prior to starting zinc supplementation had significant improvements in sperm counts and mobility; in other words, sperm did not improve unless the men had both surgery and zinc supplementation.
