Embryo Banking

Embryo banking means creating embryos via IVF now, preserving them, and then using them when you’re ready. It offers a powerful way to reduce the impact of age-related fertility decline and gives you more control over your family-building timeline.

At Bay IVF, we guide you through each step—so you understand clearly what it involves, when it’s an appropriate option, and how it fits your goals.

Who Might Choose Embryo Banking?

You might consider embryo banking if you:

Want to delay pregnancy for career, education, travel, or personal reasons.
Are concerned about age or ovarian reserve and want to “get ahead” of decline.
Plan to have multiple children in the future and want to preserve options.
Wish to create a “fertility safety net” for peace of mind.

As always, we help you assess whether it’s a good fit based on your unique fertility profile and life plans.

Our Approach – Gentle, Expert, Personalized

Individualized stimulation: Our protocols are tailored to your body so you get “quality over quantity” of eggs and embryos, reducing unnecessary stress.

Minimized disruption: Many patients continue their everyday lives while undergoing banking cycles.

Clear timeline & cost: We outline how many cycles may be needed, what to expect, the costs involved, and what is included.

Storage & later use: Once embryos are frozen (vitrified) and stored, you can use them later when you’re ready to move forward. The embryo’s age at use has far less impact than the age at creation.

What the Embryo Banking Process Looks Like

Ovarian stimulation

A personalized stimulation schedule begins, with monitoring (blood work & ultrasounds) to optimize egg development.

Egg retrieval

A brief, outpatient procedure under sedation. Our team ensures comfort and safety.

Fertilization of eggs

Evidence of fertilization can be seen the next day. The fertilized eggs are then transferred into a growth medium and cultured in our laboratory.

Culture of embryos

Your eggs are retrieved, combined with sperm (or ICSI is done when indicated)

Embryo cryopreservation

High-quality embryos are vitrified (cryopreserved).

Embryo storage in liquid nitrogen

After cryopreservation, the embryos are transferred to a liquid nitrogen storage chamber at our Clinic.

Subsequent Frozen Embryo Transfer

When you’re ready, one or two embryos will be thawed and transferred with the same care as a fresh cycle (Frozen Embryo Transfer).

Below is an example of an Embryo Banking treatment cycle. Your individualized protocol may take less or more time to complete.

Key Considerations & Success Factors

Age at embryo creation matters most — Younger maternal age at creation generally improves outcomes.
The more quality embryos banked, the more flexibility you have for future family-building.
Storage fees and long-term planning — Cryopreservation works long term; we’ll review storage terms, what happens if you pause, etc.
Realistic expectations — Banking gives you options, not guarantees.
Ethical & personal reflection — Banking involves emotional, financial, and logistical decisions; we’ll support you through them.

Is Embryo Banking Right for You?

If you’re thinking ahead — rather than reacting to urgent fertility decline — embryo banking may be a wise strategy. At Bay IVF, we’ll help evaluate:

Your ovarian reserve, AMH, AFC, and partner’s fertility
Your timeline and family-building goals
How banking compares vs immediate transfer or other fertility preservation options (e.g., egg freezing)

Call us to explore your unique profile and decide what fits best.

Bay IVF Early Pregnancy Heartbeat

Treatment Prerequisites

Only a few treatment prerequisites are required before your treatment begins. They assess the egg and sperm quality and ensure that embryos can be accurately placed in a healthy uterus.

The probability of a successful IVF treatment declines sharply after age 44. You must be 43 and 11 months or younger at the time your IVF treatment begins. Patients who are 44 and older should strongly consider Donor Egg IVF as the most effective treatment option to achieve a successful pregnancy.

Your BMI must be no greater than 31 for an adequate ovarian response and safety during the egg retrieval procedure. If your BMI is higher, please follow the IVF Diet and Lifestyle (PDF) recommendations as closely as possible. By doing so, you can achieve weight loss at an optimal rate, which could significantly improve your chances of a successful pregnancy.

This testing is required by the State of California. You and your partner (if applicable) must be tested for Hepatitis B-Surface Antigen, Hepatitis C-Antibody, HIV I&II, HTLV I&II (male partner only), and RPR.

ORA assesses the likelihood of producing normal-quality eggs. It involves measuring Follicle Stimulating Hormone (FSH), estradiol (estrogen, E2), and Anti-Mullerian Hormone (AMH) levels in blood.

These test results are used to optimize ovarian stimulation.

The number of antral follicles (small fluid-filled sacs within the ovaries seen on ultrasound) in unstimulated ovaries is related to the quality of the eggs. Ideally, there should be approximately 20 antral follicles in both ovaries combined.

The male partner’s semen will be evaluated at Bay IVF to determine the best laboratory method for semen preparation for egg insemination.

All prospective parents should consider genetic screening for hundreds of the most common genetic diseases. Please inform us during your initial appointment at Bay IVF if you would like to have your blood sample sent for genetic screening.

Environmental factors significantly impact reproductive health. Please review the IVF Diet and Lifestyle document (PDF) for a comprehensive list of environmental reproductive health recommendations and a source for dietary supplements.
