A 2016 study by Marci et al., showed that 43% of infertile women tested positive for HHV-6 with 0% of the fertile women testing positive for the virus. The authors of this PLOS study concluded that HHV-6 may reactivate due to hormonal changes which could make the uterine environment inhospitable for implantation and fetal development. Further clinical studies are needed to determine the role that HHV-6 plays in fertility.
Coppe Laboratories’ HHV-6 IHC testing has proven to be a highly sensitive and specific method for determining active HHV-6 in tissue biopsy samples.
