Choosing an IVF clinic is one of the most important decisions you will make. At Spring Fertility Denver, your care is led by the physician you chose, not a rotating provider, and personalized around your unique fertility goals. Combining nationally recognized physicians, an advanced IVF laboratory, and compassionate, individualized care, Spring Fertility is bringing a new standard of fertility treatment to Denver.
Why Patients Choose Spring Fertility Denver
Spring Fertility Denver offers a full range of treatments for individuals and couples at every stage of family building. Services include:
Natalia M. Grob, MD, Medical Director, Spring Fertility Denver
Dr. Grob is a board-certified Reproductive Endocrinologist with dual ABOG certification in OBGYN and Reproductive Endocrinology and Infertility. She completed her REI fellowship at the University of Colorado Denver and brings nearly a decade of clinical experience in Colorado fertility care, most recently serving as Medical Director at Kindbody Denver.
Her work extends beyond the clinic. Dr. Grob is a published researcher and invited lecturer on the impact of environmental exposures on reproductive health, a focus that shapes how she approaches each patient’s unique situation. At Spring Fertility Denver, she brings that same depth of expertise to every consultation, retrieval, and transfer.
Spring Fertility proudly serves patients throughout Denver, Aurora, Lakewood, Littleton, Centennial, Highlands Ranch, Boulder, and surrounding Colorado communities.

At Spring Fertility Denver, we walk you through every step of IVF with transparency and care. There are no surprises. Just a clear plan built around your unique case.
Your first visit is a deep dive into your situation. Your physician reviews your medical history and family-building goals, and all initial visits include a pelvic ultrasound to assess your antral follicle count and uterine health. Most additional testing can be completed within one menstrual cycle of your initial consultation, so you’re not left waiting.
This phase typically runs 8–12 days and is the most time-intensive part of the cycle. You’ll self-administer 2–3 hormone injections per day using small needles, and come in for approximately 4–6 monitoring visits so we can track how your follicles are developing. We adjust your dosage based on your body’s response, because no two cycles are the same.
Once your eggs are ready, we retrieve them during a 20-minute procedure performed under anesthesia. You’ll check in about an hour beforehand, meet our anesthesiologist and embryologist, and wake up in our recovery area roughly 45 minutes later. Most patients return to normal activities the following day.
On retrieval day, sperm is processed in our Andrology lab, where embryologists select the healthiest, most motile sperm for fertilization. Depending on your situation, your physician may recommend conventional IVF or ICSI (intracytoplasmic sperm injection). We support all paths to parenthood, including coordinating donor sperm for LGBTQ+ family building. Embryos are monitored carefully over 5–6 days as they develop toward the blastocyst stage.
The final step is the transfer itself, timed precisely to your cycle and treatment plan. If preimplantation genetic testing (PGT) is performed, only chromosomally normal embryos are transferred. About 11–13 days after the transfer, you’ll return for a pregnancy blood test. We know the wait is hard. Our team is with you every step of the way.
Spring Fertility publishes its outcomes data annually through SART, because transparency is part of how we practice. Because Spring Fertility Denver is a new clinic, its outcomes data will be reported through SART after two full years of operation. In the meantime, you can view the most recent published success rates for Spring Fertility’s San Francisco clinic on our SART profile.

The $250 initial consultation is a thorough, personalized planning session. It includes a review of your medical history, a full fertility assessment with physical exam and pelvic ultrasound, and a customized treatment plan with transparent next steps. You’ll leave knowing your options and what comes next. The fee also includes a follow-up summary and the opportunity to ask additional questions after your visit.
Consultations, morning monitoring, and non-surgical assessments will take place at our Denver clinic, which features well-equipped exam rooms and an on-site phlebotomy lab. Egg retrievals and embryo transfers will be performed at a partner lab and surgery center located within 30 minutes of the clinic. We’ll share the exact address as we approach our opening date.
IVF may be the right path if you have been trying to conceive without success, have a diagnosed fertility condition such as blocked fallopian tubes, endometriosis, or low sperm count, or are building your family through donor sperm or eggs. Spring Fertility Denver also provides dedicated support for LGBTQ+ family planning. The best way to know if IVF is appropriate for your situation is to schedule a consultation with Dr. Grob, who will review your history and ovarian reserve before making any recommendation.
A typical IVF cycle at Spring Fertility takes approximately 4 to 6 weeks from initial consultation through embryo transfer. The stimulation phase runs 8 to 12 days. Most additional testing can be completed within one menstrual cycle of your first visit, so you are not waiting long before your cycle begins. Your physician will give you a personalized timeline based on your specific protocol.
Colorado’s fertility insurance law (SB 23-089), effective January 2025, requires large group health plans to cover fertility diagnosis and treatment, including IVF. If your employer-sponsored plan covers 100 or more employees, your insurance may cover part or all of your IVF cycle. Coverage varies by plan, and Spring Fertility’s dedicated financial navigator will review your specific benefits and map out your out-of-pocket costs before your first cycle.

If you have frozen embryos stored elsewhere and would like to continue your care at Spring Fertility Denver, our team can coordinate the transfer and review your embryo history before planning your next steps. Contact us to discuss your specific situation.
Yes. Spring Fertility welcomes patients seeking a second opinion on their fertility diagnosis or treatment plan. A second opinion consultation with Dr. Grob includes a full review of your prior testing, medical records, and any previous treatment cycles.

Spring Fertility Denver is designed to make every visit feel purposeful and unhurried. From your first consultation through monitoring, retrieval, and transfer, here is what patients can expect.
