The missing measurement

When patients don't know their implantation risk, it's hard for them to commit.

Even with a perfect embryo, pregnancy isn't guaranteed. Until now, there's been no scientifically robust way to measure endometrial fertility. No way to distinguish chance failure from endometrial dysfunction and tell in advance who is likely to be successful from who will likely face a long road.

Not knowing what to expect results in patients hesitating to start treatment, dropping out when they experience a setback, and being dissatisfied with their care. For the first time, Simbryo provides a measure of endometrial fertility, giving you and your patients the confidence to move forward with treatment.

Why it matters

Over half of IVF patients quit treatment before reaching their goals, costing your clinic millions.

The most common reason patients cite is lack of success. Confident patients are more likely to start treatment, stick with treatment, and ultimately to be successful.

Simbryo science

Endometrial organoid medicine.

Imagine if we could simulate implantation in the lab before embryo transfer. Simbryo uses a patient's own biopsy tissue to grow an organoid model of their endometrium and test whether it is capable of implantation in vitro.

Organoids are treated with estrogen and progesterone to mimic the menstrual cycle.

Blastoids (synthetic blastocysts) implant in the organoids of fertile patients, but not in those with endometrial problems.

Receptivity is quantified via hCG secretion of implanted blastoids and tissue imaging.

The gift of knowing

Patients are likely to stick with treatment when they know what to expect.

Provide the most advanced success prediction with Simbryo precision diagnostics.

Simbryo assesses your patients' endometrial fertility and combines it with their clinical and reproductive profile, delivering the most complete prognosis so they can move forward with confidence.

Normal Simbryo Score

Rule out endometrial dysfunction and retain patients, especially after a setback.

While pregnancy can never be guaranteed, patients with a normal Simbryo score can feel reassured that they have an excellent chance of success and should stick with treatment.

Low-Normal Simbryo Score

Help your patients plan for the journey ahead, keeping them on the course.

A negative result when you expect success feels crushing. A negative result when you know the odds are long feels expected. Knowing what to expect lets patients plan ahead, giving them the wherewithal to stick with treatment.

Low Simbryo Score

Identify patients with poor prognosis and help them move to alternative treatment sooner.

Recurrent implantation failure is relatively rare, but identifying it before a patient undergoes multiple failed cycles enables you to guide them toward alternative treatments or surrogacy sooner, before wasting valuable embryos, time, money, and emotional reserve.

Additional benefits

Run multiple tests from a single biopsy sample — convenient and cost effective for you and your patients.

Get started immediately with an easy, integrated workflow and dedicated support.

Option to bank endometrial biopsy samples taken during hysteroscopy or egg retrieval if the patient isn't ready for Simbryo testing now.

We have made great strides optimizing the embryo side of IVF, but the endometrium has remained much more difficult. Identifying why implantation is not successful is groundbreaking.
