MedicalResearch.com: What is the background for this study?
Response: Infertility affects approximately 6% of 15-44 year old women or 1.5 million women in the US, according to the CDC. Approximately 25% of female infertility cases are unexplained, leaving women with few options other than expensive fertility treatments. Researchers are trying to identify factors and mechanisms at the basis of this condition.
MedicalResearch.com: What are the main findings?
Response: We found that the little-known member of the human herpesvirus family called HHV-6A infects the lining of the uterus in 43% of women with unexplained infertility but cannot be found in that of fertile women.
Little is known about HHV-6A, which was discovered in 1986 and is one of nine human herpesviruses. Others include Epstein Barr virus, varicella-zoster virus, cytomegalovirus, and herpes simplex types 1 and 2. Since HHV-6A is typically not detectable in the blood or saliva, its true prevalence is unknown and its implication in human pathologies is still controversial.
MedicalResearch.com: What should readers take away from your report?
Response: We think that the virus could make underlying fertility problems worse.
MedicalResearch.com: What recommendations do you have for future research as a result of this study?
Response: The next steps will be to determine further whether infertile condition is due to the virus, or to changes in endometrial immune system caused by the virus.
MedicalResearch.com: Is there anything else you would like to add?
Response: This work opens up a new frontier in the struggle against fertility problems: women with fertility problems could take advantage in antiviral therapy to re-create a receptive endometrial environment.
