Unexplained infertility accounts for 25% of infertility cases. In these cases there is not an obvious reason why a woman cannot get pregnant and stay pregnant. She has gone through the check list of common reasons and not found a solution. One area that is often overlooked is hidden pathogens like viruses. Pathogens are disease-causing organisms like parasites, bacteria, fungal or viral infections. These oddball infections will not show up on your normal lab or fertility panels but have to have special testing.

Viruses and Infertility

One Italian study found a strain of herpes virus known as HHV-6A in the uterine lining of 43% of women with unexplained infertility but not in the uterine lining of fertile women. The herpes virus family includes several viruses, including Epstein Barr virus, varicella-zoster virus, cytomegalovirus, and herpes simplex. Some studies have indicated that Epstein Barr virus is connected to infertility.

Another example of virus being connected to infertility is the adeno-associated virus. Abnormal semen samples from almost 100 men found that 38% of abnormal samples were infected with adeno-associated virus. This is not considered a disease causing virus, but evidence suggests it might be connected to infertile sperm.

When a virus is in the body the immune system is always on alert, possibly causing the uterine lining to be less friendly to a pregnancy. Viruses cause the body to produces, more immune cells, called cytokins, which attack foreign substances in the body and may attack a fertilized egg.

Viruses, such as Epstein Barr and others, are opportunistic in nature. You might not even realize you have the virus, but it will pop up when you are run down or be causing problems under the surface that you don’t see.

These are a few examples of viruses known to effect fertility rates. It is not a far reach to believe that other virus that have not been studied also effect fertility. Natural fertility specialists look outside of normal causes and have had great success in helping couples conceive and stay pregnant after eradicating viruses with natural protocols.

What To Do

When there is not a blaring reason for infertility always investigates oddball pathogens.  I recommend running the GI map, which looks at several viruses including Epstein Barr virus, Cytomegalovirus, Adeno virus, and Norovirus. It also looks at other pathogens besides viruses that could impact fertility.
