The Spring Difference

We believe everyone deserves to have a family if they want one. We opened Spring Fertility because you deserve care that focuses on you. We’re scientists, but we’re also spouses and parents and have been patients too.

 IVF Success Rates*


When it comes to your fertility journey, maximizing outcomes at every step of the process can make the difference of a lifetime. We’re proud of our superior results.

*Please note: We encourage more than one retrieval for some patients undergoing preimplantation genetic screening and diagnosis prior
to embryo transfer to increase the likelihood of future additional successful pregnancies. This practice may have impacted our results.

**Please note: We perform a significant number of minimal stimulation cycles, which may impact our results.

At Spring, we believe in treating every patient like an individual and working together in partnership to help them achieve their goals. For patients who want the greatest possible chance of success to have multiple children in the future, we often recommend egg or embryo banking cycles – this is not effectively captured in our SART success rates (And lowers them by increasing the denominator). We also work with many patients who have been told by other clinics that they should consider donor eggs. We welcome the hardest cases even if they adversely affect our outcomes, because we believe strongly in doing the right thing by our patients.


Book a consult




Spring is truly an amazing place, what the doctors and the entire staff do, (from door to lab) every day for others is truly selfless.  I felt that every individual we met in our process was invested in our success to conceive.  We shared tears together, we shared laughs and when our hope seemed lost they never gave up on us & never lost hope with us. They treated us with kindness, and as humans tailoring a plan that worked for our story.

L & B, Fertility Patient

Listen to Dr. Peter Klatsky on the Progyny podcast. In this podcast, we speak with a patient who shares her story of a successful pregnancy with Spring after years of failed attempts at two other centers where she was told she needed donor eggs and a gestational carrier.  She ultimately conceived with her own eggs and carried her own baby after treatment with our team. 


Our Lab Recreates the Uterine Environment


Our IVF lab continues to produce exceptional live birth rates year after year, while developing patent pending technology and cutting-edge research. We’re the first fertility center in the country to create laboratory technology that replicates the atmospheric composition of a woman’s fallopian tubes through each stage of IVF — from egg collection, to fertilization, culture, and even embryo testing.

Our state-of-the-art lab is not only producing exceptional results, but also developing fertility preservation techniques unlike anyone else — we even have patents pending.

Individualized Protocols

A “one size fits all” approach doesn’t work in fertility care. We make every egg count, offering minimal stimulation protocols, fresh transfers and recommending egg or embryo banking cycles where appropriate. We never want our patients to feel like a number.

The Spring Promise


If our patients freeze a specific number of eggs at Spring (20 eggs before age 35 or 30 eggs before 38) and are unable to achieve a successful pregnancy with us in the future, we will refund all money paid to Spring directly for your egg freezing cycle*. No other clinic in the Bay Area offers a guarantee of this kind.

*IVF, anesthesia, and medications do not qualify for money back.


We want you to have the best care possible, from start to finish. We know a big part of  service is making treatment as easy and as convenient for you as possible. That’s why our locations offer extended hours, in-house services like HSGs, telehealth services, and dedicated care teams. We even offer espresso and warm robes – because we know the little things count.
