Life on
your terms.

Knowledge is
reproductive power.

Prelude, a leader in reproductive science and technology, helps people have healthy babies when they’re ready. Whether you’re just getting started in life or have been at it awhile, if you’re not ready today but might be someday, if the family you want is different than the family you came from, you now have options.

As more people delay childbirth into their 30s and 40s to complete their education, pursue their dream job, or find their soulmate, reproductive clarity becomes more and more important. The Prelude Method is designed to give you the most reproductive choices and control over your biological clock.


The Prelude Method,

1. Fertility Preservation

Women’s eggs and men’s sperm are frozen during their peak fertility years—20s and early 30s. Contrary to popular belief, it’s not just women’s eggs that carry risks associated with declining fertility. Advancing paternal age also has been associated with higher incidence in offspring of illnesses such as autism and bipolar disorder.

2. Embryo Creation

When ready to start a family, eggs and sperm are unfrozen and combined to create embryos.

3. Genetic Screening

Before the embryo is implanted, parents are screened for common inherited diseases. If parental testing reveals risks, the embryos are tested for genetic diseases. Embryos are also tested for chromosomal abnormalities. As genetic screening improves, the number of illnesses that can be detected will rise over time, and so will the chances of having a healthy baby.

4. Single Embryo Transfer

An embryo is selected that will maximize the likelihood of a healthy birth.

By coupling earlier decision making with the latest reproductive science and technology, The Prelude Method can dramatically increase the probability of having a healthy baby and decrease the chances of requiring infertility therapy later in life.
