Stop guessing why pregnancy isn't happening
A hidden uterus virus, HHV-6A, can quietly block embryos from implanting—even when all your tests look "normal."
We help you check for this virus at home, so you and your doctor can make better decisions with less guesswork.
Why a "silent" virus can block pregnancy
HHV-6A is a uterus-focused virus. Most standard fertility workups never look for it.
- It can live quietly in the lining of your uterus.
- It can cause tiny amounts of inflammation that make it harder for an embryo to stick.
- It's treatable—but only if someone actually checks for it.
coVee™ helps you check for HHV-6A with an at-home menstrual fluid test. No surgery. No needles.
Why this virus could be your missing piece:
Many Women Have It
In one study, 43% of women with "unexplained infertility" tested positive
Testing is Simple
With coVee™, you collect a small sample from your period at home. No needles. No surgery.
Treatment Can Help
