FAQs
What is Nucleus Embryo?
add
Nucleus Embryo starts with you. Using Nucleus Preview, both parents are screened for 2,000+ genetic conditions to uncover what you could pass on. Then, your embryos are analyzed in depth — with predictions for traits like height and intelligence, and risk assessments for conditions like heart disease, type 2 diabetes, and Alzheimer's. So when it's time to choose which embryo to transfer, you have the full picture.
If Nucleus Preview reveals you're a carrier for a rare condition, it may mean PGT-M testing is right for your embryos. Your physician and our genetic counselors are there to walk you through it — you'll never have to navigate it alone.
