Hereditary disorders
As part of Nucleus Embryo, a Nucleus Preview test that screens for 2000+ hereditary diseases* is included for both parents
* If a higher risk for inherited diseases, like cystic fibrosis or Tay-Sachs, is identified, parents can choose to take an extra step to test embryos, such as PGT-M, which checks embryos against specific conditions.
We're here to change lives.
We concluded that Nucleus was the one and only company that best reflected our values.
Nucleus carefully analyzed the genome of every single one of our embryos and gave us a report on which embryos were likely to grow into adults with a long healthy life.
In our opinion, every single intended parent that is doing IVF should consider Nucleus.

Common questions
FAQs
What is Nucleus Embryo?
add
Nucleus Embryo is a software designed for couples to give their children the best possible start in life. Parents can analyze, compare, and select their embryos based on 2000+ genetic predictions, including health conditions, physical traits, and personality indicators.
Rare conditions like cystic fibrosis and Tay-Sachs disease are screened in parents using Nucleus Preview. If any increased risk is identified for these 2000+ conditions, parents can choose to screen embryos with their PGT lab using PGT-M.
Am I eligible for Nucleus Embryo?
add
If you’re undergoing or have undergone IVF, then you are eligible for Nucleus Embryo. With Nucleus Embryo, you’ll get clear, personalized insights into everything from disease risks to physical traits.
What's included?
add
Nucleus Embryo provides insights into a wide range of genetic analyses, including:
Appearance and traits: Eye color, height, hair color (coming soon), male-pattern baldness, severe acne
Body and physical health: BMI, chronic pain, left-handedness, osteoarthritis, rheumatoid arthritis
Women’s health: Endometriosis, PCOS
Nutrition and metabolic conditions: Alcohol dependence, celiac disease, type 2 diabetes
Heart health: Coronary artery disease, hypertension
Cancers: Breast cancer, male breast cancer, ovarian cancer, gastric cancer, prostate cancer, colorectal cancer
Neurological and mental health: ADHD, Alzheimer’s, anxiety, bipolar disorder, depression, insomnia, migraine, multiple sclerosis, OCD, Parkinson’s disease, schizophrenia, intelligence
Other conditions: Asthma, age-related macular degeneration, restless legs syndrome, seasonal allergies

Why use Nucleus Embryo?
add
Most fertility clinics only screen for viability and a limited set of rare genetic diseases. Nucleus Embryo goes far beyond that, offering comprehensive insights about your embryos’ future health and traits. Unlike clinical reports, our interface is designed specifically for future parents: intuitive, clear, and emotionally supportive.
Is this scientifically credible?
add
Yes. Our analysis is based on validated, peer-reviewed research and built on the latest genetic technology. The science is rigorous, and the experience is human: designed with care, transparency, and responsibility.

Is this gene editing?
add
No, embryo selection and gene editing are not the same thing.
When undergoing IVF, couples typically have several viable embryos to choose from.
Nucleus Embryo provides information on the disease risks and traits of each of these embryos, helping parents make an informed choice on which embryo they want to implant.
Can Nucleus design my baby?
add
DNA is not destiny.
Genetics can be a helpful tool for choosing an embryo, but it’s not a guarantee. Genetic research is still in it’s infancy, and there’s still a lot we don’t know about how DNA shapes who we are.
A higher genetic risk doesn't mean an embryo will certainly develop a condition later in life, just as a lower risk doesn't mean they won’t.
Besides genetics, environmental factors, lifestyle choices, and other factors also significantly influence a person’s chance of developing a condition and who they are.
