The female cycle, sperm production, the cell maturation and ovulation are all extremely complex processes and dysfunction can therefore easily occur. It is believed that the two main causes for the sharp rise in infertility are:
Deficiency of micronutrients (amino acids, vitamins, trace elements and minerals)
“Environmental toxins” are pesticides, air pollutants and poisons, which we voluntarily expose ourselves to such as nicotine, alcohol and drugs. Something all environmental toxins have in common in addition to their direct potential harm is that they contribute to a deficiency in micronutrients and antioxidants. Other causes include infections and the increased levels of oestrogen in the diet and drinking water.
Looking at the supply of micronutrients in relation to a planned pregnancy, it is not just a matter of ” pregnant “or” not pregnant “, but when it comes to an actual pregnancy, it becomes a question of” healthy pregnancy with optimal conditions for the unborn “or” riskypregnancy “.
L-carnitineis an amino acid that helps the body turn fat into energy. Therefore, L-carnitine is an essential part of both the development and ability to swim of human sperm cells.
In various studies it has been demonstrated that a low L-carnitine levels are associated with poor sperm count (oligozoospermia).
L-carnitine is directly related to the maturation and development of healthy sperm:
High concentrations of L-carnitine in the epididymis support the developmental process of the spermatozoa.
L-carnitine is essential to provide the sperm with energy.
L-carnitine directly influences positive sperm motility and development (as demonstrated in several studies. 1
As an antioxidant L-carnitine protects the sperm directly from cell damage and may increase the number of healthy sperm.
The body can only produce the neurotransmitter NO (nitric oxide) from the amino acid L-arginine. NO is responsible for the control of vascular tone. For men, this means that for a good erection, sufficiently high L-arginine levels must be present in the blood. Therefore L-arginine is recommended for men with erectile dysfunction . L-arginine affects both erectile function and the quality of sperm:
L-arginine is a direct precursor of spermine and spermitin. As early as 1973 it was found in a study of 173 men that the administration of 4,000 mg L-arginine on a daily basis in 74% of men significantly increased numbers of sperm and sperm mobility. 2
Men with low sperm count (oligospermia) or no sperm (azoospermia) have a lower than average concentration of L-arginine in their ejaculations. 3
The sperm motility can be significantly improved by taking L-arginine over a period of six months, L-arginine has no known side effects. (4. “Scibona M, Meschini P, Capparelli S, et al. Larginine and male infertility. Minerva Urol
Often women try by all means to prevent pregnancy for more than two decades. Then when they are ready to conceive, they can hardly come fast enough.
However women often overlook that the natural fertility decreases with age:
At 25, the statistical chance is of getting pregnant is 30% per cycle;
From the age of 30 this probability decreases gradually. At 35, the probability is 15% per cycle and
at the age of 40, the probability of becoming pregnant is only 10% per cycle
To increase fertility, antioxidant vitamins, coenzyme Q10 and L-carnitine have been shown in several studies to be very promising.
Amino acids and vitamins during pregnancy and lactation
Many micronutrients influence fetal health considerably especially in the first weeks of pregnancy. The best known are:
Folic acid: More than half of the Western European population has a deficiency of folic acid. A folic acid deficiency in the first weeks of pregnancy considerably increases the risk of neural tube defects (“open back”). Folic acid should therefore be regularly taken in any case well before a planned pregnancy.
Omega-3 fatty acids: Through daily supplementation with omega-3 fatty acids, the risk of allergies can be reduced. 8 Also, there are studies that provide evidence that omega-3 fatty acids strengthen the immune system, reduce the risk of cancer, and increase intelligence.
Vitamin D: There is a general deficiency of vitamin D in Western Europe. This can be attributed to the fact that Europe experiences many months with only small amounts of sunshine. British researchers have established the connection between various childhood diseases and vitamin D deficiency and recommend that pregnant women should supplement their diet with vitamin D. 9
Sexual Prowess and Testosterone Boosting

Erectile function tends to decrease with increasing age and naturally dropping testosterone levels. This represents a major challenge for men and indeed their partners as it impacts their life in both physical and psychological ways. Mid- and long-term dysfunctions are almost always caused by circulation-based problems. They must be examined by doctors to exclude the possibility of more serious conditions.
Physiologically, the most common cause is calcification of arteries and vanes. This leads to a reduction in circulation and as a result less effective blood flow into the penis’ cavernous (spongy) body. This causes a progressively weaker erection. In addition, however, psychological factors such as stress and anxiety can play also a major role.
Several peer-reviewed studies have demonstrated how amino acids, in particular Arginine are able to contribute effectively improve erectile function. The best results were achieved when Arginine was combined with Pine Bark Extract.
These two nutrients act synergistically by increasing the production of Nitrogen Oxide (NO) whilst reducing inflammation and preserving blood vessels. This enabled them to relax effectively, increasing blood flow into the penis and eliminate back flow.
In addition, some food supplement such as VIGARIN by a company called aminoexpert combine amino acids with several other common nutrients, which may boost testosterone.
