Preserve Your Fertility. Protect Your Options.
Egg freezing is about preserving options.
If you’re focused on your career, waiting for the right partner, planning for the future, or facing a medical condition that could affect your fertility, egg freezing gives you the opportunity to preserve today’s eggs for tomorrow’s possibilities.
At Spring Fertility Denver, you’ll receive physician-led care from a deeply experienced fertility team with decades of experience caring for patients in Colorado, supported by a nationally recognized embryology laboratory and innovative programs designed to make fertility preservation more accessible. From your first consultation through egg retrieval, every step of your care is personalized around your health, your goals, and your future family-building plans.
If you’re ready to move forward or simply want to better understand your fertility, our team is here to provide clear answers, thoughtful guidance, and expert care every step of the way.
Choosing where you freeze your eggs is just as important as deciding when.
While many fertility clinics offer egg freezing, the quality of your physician, laboratory, clinical protocols, and overall patient experience can vary significantly. At Spring Fertility Denver, we’ve built one of the nation’s leading fertility preservation programs by combining exceptional clinical care with scientific innovation and a patient experience designed around continuity, transparency, and confidence.
Freezing your eggs is an investment in your future, and we believe you should feel confident making that investment.
The Spring Promise reflects the confidence we have in our physicians, our laboratory, and the care we provide every day. Eligible patients who freeze the recommended number of mature eggs may qualify for our money-back guarantee if those eggs do not ultimately result in a successful pregnancy, subject to program terms.
The Spring Promise isn’t simply a financial benefit. It’s an expression of our commitment to clinical excellence and our belief that patients deserve greater confidence as they preserve their fertility.
One of the biggest differences patients notice at Spring Fertility Denver is continuity of care.
At many fertility clinics, you may meet one physician during your initial consultation but see different doctors throughout monitoring appointments, procedures, and treatment. While every physician is qualified, constantly changing providers can make patients feel like they’re starting over at every visit.
At Spring Fertility Denver, your care is led by your physician from consultation through egg retrieval. You’ll continue working with the doctor who understands your medical history, developed your treatment plan, and will guide you throughout your fertility treatment.
Led by Dr. Natalia Grob, whose team has cared for fertility patients throughout Colorado for decades, Spring Fertility Denver combines trusted local expertise with nationally recognized clinical standards and one of the country’s leading fertility laboratories.
We believe continuity creates better communication, greater trust, and ultimately a better patient experience.
While patients naturally focus on choosing the right physician, fertility specialists know that the laboratory is equally important.
Every egg that is retrieved will be evaluated, frozen, stored, and eventually thawed at some point in the future inside the embryology laboratory. The quality of laboratory procedures, technology, and quality control can play an important role in protecting those eggs for future use.
Spring Fertility has long believed that laboratory excellence should be one of the defining characteristics of exceptional fertility care.
Our embryology laboratory pioneered the world’s first low-oxygen egg collection and embryo transfer program, helping create conditions that more closely resemble the body’s natural reproductive environment. Combined with rigorous quality standards, advanced cryopreservation techniques, and continuous investment in laboratory innovation, every step of the process is designed to maximize the opportunity for future success.
It’s one of the many reasons patients from across the country choose Spring Fertility for fertility preservation.
Every woman has a different ovarian reserve, medical history, timeline, and vision for building a family.
That’s why no two egg freezing cycles at Spring Fertility are exactly alike.
Before treatment begins, your physician carefully evaluates your age, hormone levels, ovarian reserve, ultrasound findings, medical history, and future family-building goals. Using that information, they’ll recommend a treatment protocol designed specifically for your body, not a standardized approach used for every patient.
Throughout treatment, your physician continues monitoring your response and adjusting medications as needed to help maximize the number of mature eggs retrieved while prioritizing your safety and comfort.
Our goal isn’t simply to freeze eggs.
It’s to help you make informed decisions and preserve the greatest number of healthy opportunities for your future.
We believe more women should have the opportunity to preserve their fertility when timing is on their side, not simply when finances allow.
Spring Fertility offers egg freezing for $9,995, including one year of storage.
We also offer:
Our philosophy is simple: fertility preservation should be transparent, understandable, and accessible.
Most people pursuing egg freezing are balancing busy careers, school, travel, relationships, and family responsibilities.
We’ve designed our program with that reality in mind.
Spring Fertility Denver offers weekend consultations and seven-day-a-week monitoring appointments, making it easier to receive the care you need while minimizing disruptions to your daily life.
Our team works closely with patients to coordinate appointments efficiently while maintaining the close clinical monitoring that’s essential for a successful egg freezing cycle.
Many people assume egg freezing is only for women who want to delay having children because of their careers.
In reality, patients choose fertility preservation for many different reasons, and every decision is deeply personal.
You may want to consider egg freezing if you:
There isn’t one perfect reason to freeze your eggs.
The right decision depends on your health, your timeline, and your future family-building goals.
Meeting with a fertility specialist can help you better understand your current fertility, estimate how your ovarian reserve compares with others your age, and determine whether egg freezing aligns with your plans for the future.
For many patients, one of the biggest sources of anxiety is simply not knowing what to expect.
Understanding each step of the process can make the experience feel much more manageable.
Most egg freezing cycles take approximately three to four weeks from your initial consultation through egg retrieval. Throughout treatment, your physician and care team will guide you through every step, answer your questions, and adjust your treatment plan based on how your body responds.
Your first appointment is designed to give you a clear picture of your fertility today.
During your consultation, your physician will review your medical history, discuss your future family-building goals, perform a pelvic ultrasound, and order fertility bloodwork to evaluate your ovarian reserve.
One important measurement is your Antral Follicle Count (AFC), the number of small follicles visible within your ovaries during an ultrasound. Combined with hormone testing, including Anti-Müllerian Hormone (AMH), AFC helps your physician estimate how many mature eggs you may be able to freeze during a cycle and how many cycles might be recommended to help you reach your goals.
Rather than simply delivering numbers, your physician will explain what your results mean, answer your questions, and help you understand the options available to you.
For many patients, this consultation alone provides valuable peace of mind, even if they ultimately decide not to move forward with egg freezing immediately.
After your evaluation, your physician will develop a medication protocol tailored specifically to your ovarian reserve and treatment goals.
Over approximately 10 to 12 days, you’ll take fertility medications that encourage multiple eggs to mature during a single menstrual cycle. Rather than releasing one egg naturally, the ovaries are gently stimulated to develop several mature eggs that can be safely retrieved.
During this phase, you’ll visit the clinic every few days for bloodwork and ultrasound examinations. These monitoring appointments allow your physician to evaluate how your follicles are developing and adjust medications if needed.
This individualized approach helps maximize the number of mature eggs retrieved while prioritizing both safety and comfort.
Most patients continue working and maintaining many of their normal daily activities throughout this portion of treatment, although strenuous exercise and certain high-impact activities are usually paused until after egg retrieval.
When your follicles have reached the appropriate stage of development, your physician will schedule your egg retrieval.
Egg retrieval is a minimally invasive outpatient procedure performed under IV sedation, allowing you to remain comfortable throughout the process. Using ultrasound guidance, your physician gently retrieves the mature eggs from your ovaries using a thin needle. The procedure itself typically takes about 20 to 30 minutes, and most patients return home the same day.
Some mild cramping, bloating, or fatigue is common for a few days after retrieval, but many patients return to work and most normal daily activities within one to two days. Your physician will provide individualized guidance regarding exercise and recovery.
Immediately after retrieval, your eggs are transferred to Spring Fertility’s embryology laboratory, where each egg is carefully evaluated for maturity.
Only mature eggs are frozen because they have the greatest potential to be successfully thawed and fertilized in the future.
Spring Fertility uses vitrification, an advanced flash-freezing technique that rapidly freezes eggs while minimizing the formation of damaging ice crystals. Compared with older slow-freezing methods, vitrification has dramatically improved egg survival after thawing and has become the standard of care in modern fertility medicine.
Once frozen, your eggs remain securely stored until you’re ready to use them. Research has shown that eggs frozen through vitrification can remain safely preserved for many years without evidence that storage time itself reduces egg quality.

One of the most common questions patients ask is: “How many eggs should I freeze?”
The answer depends on several factors, including:
There isn’t one number that’s right for everyone.
Someone hoping to have one child may have different recommendations than someone hoping to have two or three children. Likewise, recommendations for someone freezing eggs at age 30 will naturally differ from someone beginning treatment at age 37.
Rather than focusing on a single target number, your physician will help you understand how many mature eggs may provide the greatest opportunity for achieving your future family-building goals.
Many online egg freezing calculators rely primarily on published population averages.
Spring Fertility wanted to provide something more personalized.
That’s why we developed one of the industry’s first patient-facing Egg Freezing Calculators using data from more than:
combined with published medical research and clinical expertise.
Instead of relying solely on generalized estimates, the calculator provides a personalized projection based on your age and the number of children you hope to have, giving you a more meaningful starting point for conversations with your physician and helping you make more informed decisions about fertility preservation.
While no calculator can predict an individual outcome with certainty, it can meaningfully inform your planning.

One of the biggest advantages of egg freezing is that it allows you to preserve eggs at today’s age for use in the future.
While many women can and do have healthy pregnancies later in life, both the quantity and quality of eggs naturally decline over time.
This decline is gradual for some women and more rapid for others, which is why age is one of the most important factors physicians consider when discussing fertility preservation.
Freezing eggs at a younger age generally means more eggs are available and a greater percentage of those eggs are chromosomally normal, increasing the likelihood that they may result in a healthy pregnancy if used later.
That doesn’t mean there’s one perfect age to freeze your eggs.
Some women choose fertility preservation in their late twenties because they know they want children someday but aren’t ready today. Others decide in their early or mid-thirties after learning more about how fertility changes with age. Still others pursue egg freezing because of medical conditions or treatments that may affect fertility regardless of age.
The right time is highly personal.
Rather than relying on generalized advice or online information, meeting with a fertility specialist can provide individualized recommendations based on your ovarian reserve, hormone levels, medical history, and future family-building goals.
Even if you ultimately decide not to freeze your eggs, understanding your fertility today can help you make more informed decisions for tomorrow.
Spring Fertility Denver is led by Dr. Natalia Grob, a board-certified reproductive endocrinologist who has cared for fertility patients throughout Colorado for decades.
Dr. Grob believes exceptional fertility care begins with listening. She works closely with each patient to understand their goals, explain every available option, and develop a treatment plan that reflects their unique circumstances.
Supported by Spring Fertility’s nationally recognized laboratory and clinical standards, Dr. Grob and the Denver team provide fertility preservation, IVF, fertility testing, recurrent pregnancy loss evaluation, and other advanced reproductive services in a compassionate, physician-led environment.
At Spring Fertility, you’ll continue working with the physician who knows your history and understands your goals throughout your treatment.
Spring Fertility also serves egg freezing patients throughout the Denver metro area, including Aurora, Lakewood, and Boulder.
While every situation is different, egg quantity and quality are generally highest at younger ages. Many patients choose to freeze their eggs in their late twenties or early thirties, but the best time depends on your health, family-building goals, and personal circumstances.
Eggs preserved through vitrification can remain safely frozen for many years. Current research has not shown that storage time itself decreases egg quality.
No. Egg freezing does not reduce your ability to conceive naturally in the future. The eggs retrieved during treatment are part of a group of follicles that would naturally be lost during that menstrual cycle.
The procedure is performed under IV sedation, so most patients remain comfortable throughout egg retrieval. Mild cramping and bloating afterward are common but usually improve within a few days.
Most patients complete one egg freezing cycle in approximately three to four weeks, including consultation, ovarian stimulation, monitoring, and egg retrieval.
Yes. Many women with endometriosis, PCOS, diminished ovarian reserve, or other reproductive conditions successfully freeze their eggs. Your physician will recommend an individualized treatment plan based on your diagnosis and fertility evaluation.
